Best way to handle large JSON data? MAP still supported?


Recommended Posts

Hello.  I have a program that has used ADO database connection to return a query and then subsequently put the query results into an array using getrows.  See snippet below:

$constrim="DRIVER={SQL Server};SERVER=xxx-xxxxx\CSC;DATABASE=xxxxxxxxx;uid=xxxxxxxxxx;pwd=xxxxxxxxxxxx;"
$adCN = ObjCreate ("ADODB.Connection") ; <== Create SQL connection
$adCN.Open ($constrim) ;
local $sQuery = "select * from tbl_Apps"                     ; get all applications in the database
local $oAppRecordSet = $adCN.Execute($sQuery)
local $aAppsInDB = $oAppRecordSet.Getrows(5000)

With the code above I can perform array operations very efficiently. 

Now I need to get this data via JSON which is working (using Ward's JSON UDF)  but the data set returned is large (approx 4MB) and I'm wondering what is the most efficient way to get this data into an array.  

Dim $obj = ObjCreate ("WinHttp.WinHttpRequest.5.1")
$obj.Open("GET", $URL, false)
$obj.SetRequestHeader("Content-Type", "application/json")
$obj.Send()
$json = JSON_decode( $obj.ResponseText )

Any help would be appreciated!!

So what's your problem with Ward's UDF?
It seem to work for you but you search a faster solution - right?

Maybe my JSON-UDF is a good try for you.
This UDF convert a JSON-string into nested AutoIt-datastructures (strings, numbers, bools, arrays, dictionaries).

But it shouldn't be faster than Ward's because it's written in native AutoIt. Ward's based on a professional external JSON-parser.

Anyway - here's an example of how to use:

#include <JSON.au3>
Global $s_String = '[{"id":"4434156","url":"https://legacy.sky.com/v2/schedules/4434156","title":"468_CORE_1_R.4 Schedule","time_zone":"London","start_at":"2017/08/10 19:00:00 +0100","end_at":null,"notify_user":false,"delete_at_end":false,"executions":[],"recurring_days":[],"actions":[{"type":"run","offset":0}],"next_action_name":"run","next_action_time":"2017/08/10 14:00:00 -0400","user":{"id":"9604","url":"https://legacy.sky.com/v2/users/9604","login_name":"robin@ltree.com","first_name":"Robin","last_name":"John","email":"robin@ltree.com","role":"admin","deleted":false},"region":"EMEA","can_edit":true,"vm_ids":null,"configuration_id":"19019196","configuration_url":"https://legacy.sky.com/v2/configurations/19019196","configuration_name":"468_CORE_1_R.4"},{"id":"4444568","url":"https://legacy.sky.com/v2/schedules/4444568","title":"468_CORE_1_R.4 Schedule","time_zone":"London","start_at":"2017/08/11 12:00:00 +0100","end_at":null,"notify_user":false,"delete_at_end":false,"executions":[],"recurring_days":[],"actions":[{"type":"suspend","offset":0}],"next_action_name":"suspend","next_action_time":"2017/08/11 07:00:00 -0400","user":{"id":"9604","url":"https://legacy.sky.com/v2/users/9604","login_name":"robin@ltree.com","first_name":"Robin","last_name":"John","email":"robin@ltree.com","role":"admin","deleted":false},"region":"EMEA","can_edit":true,"vm_ids":null,"configuration_id":"19019196","configuration_url":"https://legacy.sky.com/v2/configurations/19019196","configuration_name":"468_CORE_1_R.4"}]'

      Hi friends,
      I'm using json.au3 to register some data in my server, everything work fine except the data that i send in utf8 format like names saved as ????? .
      i think something mess with inetget cause this problem
      can you help me please?
      $sAdditionalData = "secret_key=" & $secret_key_verify & "&slm_action=slm_check&license_key=" & $license_key&"&first_name="&$first_name $data = _INetGetSource($sDomain&'/?'&$sAdditionalData) $object = json_decode($data) Json_Dump($data) $response = json_get($object, '.first_name')

      I was searching for a way to highlight zones (regions, provinces, counties, etc) on a map, and I don't need  super precise maps so I wrote this script, based on picking up black and white maps (2 colors BW .png or .gif tested) and filling them with colors, writing down a sqlite database to associate zones with names (and other data as well), and reuse the map and the DB to display data, in my example reading a simple .txt file.
      It's all based on this thread  and this other thread.

      So I have two modes:
      The Map "creation mode" : you provide a map image and you start to pick up colors, set "upper level" region/state, and by clicking on a region you fill it and you name it, and all the data are saved on a sqlite DB (auto-created) when you have the map image and a DB with the correct associations, you can switch the "mode" to "show" (as by .ini file) and the script tries to read a "datafile" showing the zone names listed in datafile. The code:

      To test, copy all in a single folder and adjust the mapflooder.ini, also you can add to you includes the _gollog.au3 (used for log, you can avoid it deleting all Gollog() lines)

      Introduction
      JSON (Javascript Object Notation) is a popular data-interchange format and supported by a lot of script languages. On AutoIt, there is already a >JSON UDF written by Gabriel Boehme. It is good but too slow, and not supports unicode and control characters very well. So I write a new one (and of course, fast one as usual).

      I use a machine code version of JSON parser called "jsmn". jsmn not only supports standard JSON, but also accepts some non-strict JSON string. See below for example.
       
      Important Update!!
      I rename the library from jsmn.au3 to json.au3. All function names are changed, too.
       
      Decoding Function
      Json_Decode($Json) $Json can be a standard or non-standard JSON string. For example, it accepts:
      { server: example.com port: 80 message: "this looks like a config file" } The most JSON data type will be decoded into corresponding AutoIt variable, including 1D array, string, number, true, false, and null. JSON object will be decoded into "Windows Scripting Dictionary Object" retuned from ObjCreate("Scripting.Dictionary"). AutoIt build-in functions like IsArray, IsBool, etc. can be used to check the returned data type. But for Object and Null, Json_IsObject() and Json_IsNull() should be used.

      If the input JSON string is invalid, @Error will be set to $JSMN_ERROR_INVAL. And if the input JSON string is not finish (maybe read from stream?), @Error will be set to $JSMN_ERROR_PART.

      Encoding Function
      Json_Encode($Data, $Option = 0, $Indent = "\t", $ArraySep = ",\r\n", $ObjectSep = ",\r\n", $ColonSep = ": ") $Data can be a string, number, bool, keyword(default or null), 1D arrry, or "Scripting.Dictionary" COM object. Ptr will be converted to number, Binary will be converted to string in UTF8 encoding. Other unsupported types like 2D array, dllstruct or object will be encoded into null.

      $Option is bitmask consisting following constant:
      $JSON_UNESCAPED_ASCII ; Don't escape ascii charcters between chr(1) ~ chr(0x1f) $JSON_UNESCAPED_UNICODE ; Encode multibyte Unicode characters literally $JSON_UNESCAPED_SLASHES ; Don't escape / $JSON_HEX_TAG ; All < and > are converted to \u003C and \u003E $JSON_HEX_AMP ; All &amp;amp;amp;amp;s are converted to \u0026 $JSON_HEX_APOS ; All ' are converted to \u0027 $JSON_HEX_QUOT ; All " are converted to \u0022 $JSON_PRETTY_PRINT ; Use whitespace in returned data to format it $JSON_STRICT_PRINT ; Make sure returned JSON string is RFC4627 compliant $JSON_UNQUOTED_STRING ; Output unquoted string if possible (conflicting with $JSMN_STRICT_PRINT) Most encoding option have the same means like PHP's json_enocde() function. When $JSON_PRETTY_PRINT is set, output format can be change by other 4 parameters ($Indent, $ArraySep, $ObjectSep, and $ColonSep). Because these 4 output format parameters will be checked inside Jsmn_Encode() function, returned string will be always accepted by Jsmn_Decode(). $JSON_UNQUOTED_STRING can be used to output unquoted string that also accetped by Jsmn_Decode().

      $JSON_STRICT_PRINT is used to check output format setting and avoid non-standard JSON output. So this option is conflicting with $JSON_UNQUOTED_STRING.

      Get and Put Functions
      Json_Put(ByRef $Var, $Notation, $Data, $CheckExists = False) Json_Get(ByRef $Var, $Notation) These functions helps user to access object or array more easily. Both dot notation and square bracket notation can be supported. Json_Put() by default will create non-exists objects and arrays. For example:
      Local $Obj Json_Put($Obj, ".foo", "foo") Json_Put($Obj, ".bar[0]", "bar") Json_Put($Obj, ".test[1].foo.bar[2].foo.bar", "Test") Local $Test = Json_Get($Obj, '["test"][1]["foo"]["bar"][2]["foo"]["bar"]') ; "Test" Object Help Functions
      Json_ObjCreate() Json_ObjPut(ByRef $Object, $Key, $Value) Json_ObjGet(ByRef $Object, $Key) Json_ObjDelete(ByRef $Object, $Key) Json_ObjExists(ByRef $Object, $Key) Json_ObjGetCount(ByRef $Object) Json_ObjGetKeys(ByRef $Object) Json_ObjClear(ByRef $Object) These functions are just warps of "Scripting.Dictionary" COM object. You can use these functions if you are not already familiar with it.
       
      == Update 2013/05/19 ==
       
      * Add Jsmn_Encode() option "$JSMN_UNESCAPED_ASCII". Now the default output of Json_Encode() is exactly the same as PHP's json_encode() function (for example, chr(1) will be encoded into u0001).
      $JSON_UNESCAPED_ASCII ; Don't escape ascii charcters between chr(1) ~ chr(0x1f)  
      == Update 2015/01/08 ==
      * Rename the library from jsmn.au3 to json.au3. All function names are changed, too.
      * Add Json_Put() and Json_Get()
      * Add Null support
      * Using BinaryCall.au3 to loading the machine code.
       
      == Update 2018/01/13==   (Jos)
      * Add JsonDump() to list all Json Keys and their values to easily figure out what they are.
      == Update 2018/10/01==  (Jos)
      * Fixed JsonDump() some fields and values were not showing as discussed here  - tnx @TheXman .

      This UDF brings the power and flexibility of jq to AutoIt scripts.  jq is an open-source, powerful, and flexible command-line based JSON processor.  As it says on their website, jq is like 'sed' for JSON.  jq can be used for the simplest of tasks like retrieving JSON objects and values (parsing), to very advanced JSON processing using its numerous built-in functions and conditional processing.  Its built-in functions can handle math, selection, conditional processing, mapping, object and array manipulation, flattening, reduction, grouping, and much more.  You can even create your own jq functions.  You can learn more about jq and even play with it in real-time, using jq's online jq playground, all on their website.
      Here and some helpful links to get you more familiar with jq, what can be done with it, its built-in functions, and its syntax.
      jq Website: https://stedolan.github.io/jq/ jq Manual: https://stedolan.github.io/jq/manual/ jqWiki (FAQ, Cookbook, Advanced Topics) https://github.com/stedolan/jq/wiki jq Online Testing Playground: https://jqplay.org/ jq is a single 32 or 64 bit executable that has no other dependencies.  Just like using the SQLite UDF, the only requirement to use this UDF is that the jq executable reside in a location in which the UDF can execute it.  The latest win32 & win64 versions have been included in the UDF download.  You can always get newer versions from the jq website.
      I don't consider this UDF as a replacement for some of the other JSON UDFs like the one based on JSMN.  If speed and simple JSON parsing are your primary goals, then other UDFs may be a better choice.  However, if you like having the power to do just about anything related to JSON processing/manipulation, using a single UDF, then jq may be worth checking out.  It can be used by novices and experts alike.  Below, is a brief explanation of how jq works, how to use the jq UDF, and a few examples of how to do some simple tasks.  If you want to learn more about jq and what it can do, I would highly suggest checking out the jq website and some of the other resources listed above.
      jq at a high level
      Like 'sed', jq reads JSON in, either through STDIN or one or more files, processes it thru one or more "filters", and outputs the results.  You can, optionally, supply "options" that affect how it reads the input, where it gets its "filters", and how it writes its output.  It looks a little like this:
      JSON ---> jq processor (using supplied filters and options) ---> Output
      So in jq lingo, you basically use "Filters" to tell jq what you want it to do.  So in the UDF file, that is why the main functions ( _jqExec() and _jqExecFile() ) refer to filters and options.  Please make note that jq works with relatively strict JSON.  This means that all JSON read must be conform to the standard.  Luckily, jq is pretty good at identifying where a format error exists in non standard JSON.
      The jq UDF
      There are 2 main funtions in the UDF file, _jqExec and jqExecFile.  With these 2 functions, you can pretty much do anything that jq can do.  The only difference between to two functions is whether the JSON is supplied by a string or a file.  The 2 primary functions simply call the jq executable with the supplied information, after properly formatting the parameters.  There are additional functions in the UDF to easily pretty-print your json, compact-print your json, dump the json data with its associated paths, and see if specific JSON keys exist, but they all just execute the _jqExec or _jqExecFile function with the proper filter.  There are also a couple of extra functions to display what version of the UDF and jq executable you are currently using.  There are also a couple of functions to enable and disable logging of jq information for debugging purposes.  Most of the jq UDF file functions return an @error if unsuccessful.  Some also include @extended info.  Please see the actual function headers for more information on their usage and return values.
      The 2 primary functions below just format your jq request and pass it on the jq executable.  The functions will also properly escape double quotes (") that are used in the filter.  For most simple tasks, you just need to supply the JSON source and a filter.
      _jqExec($sJson, $sFilter, $sOptions = Default, $sWorkingDir = Default) Or _jqExecFile($sJsonFile, $sFilter, $sOptions = Default, $sWorkingDir = Default) Using jq in your script
      As stated earlier, the jq executable must reside somewhere where the script can locate and execute it.  The _jqInit() function always has to be executed before any jq processing occurs.  _jqInit() merely locates the executable or uses the supplied path.  It also clears any previous debug log.  The jq UDF folder contains a jq example script that has several examples to how to do some of the most common JSON processing tasks.  Here are a few examples to get you started:

      How to pretty-print some JSON

      The examples above, and the ones in the example files, merely scratch the surface of what jq can do.  It may look intimidating at first but it really isn't that bad once you start playing with it.
      If you have any questions regarding the UDF, or how to perform a certain task using jq, I'll try my best to answer them.  Since jq has been around for a while now, there's also several jq-related questions and answers on StackOverflow.
      If you work with JSON, I hope you find this UDF useful as I do.
