Writing some Robot Framework tests.
Using RIDE to test some Restful Web services.
For simplicity this is the basic JSON
${Rlist} {"list" : []}
The code will generate a random number, and I need to store that in the list.
The best I think I have gotten is create a list, and try to store that value back into the JSON.
${listValue} Create List ${num}
${Rlist} Set Json Value ${Rlist} /list ${listValue}
I just get a
TypeError: expected string or buffer
I have tried to convert the JSON to a dictionary, but I can't get that working either.
Converting the list to String and removing unnecessary chars before parsing it to JSON will save your problem. Here is the complete code for your reference.
${Rlist} Set Variable {"list":[]}
${listValue} Create List
:FOR ${index} IN RANGE 5
\ ${random_number} Generate Random String 8 [NUMBERS]
\ Append To List ${listValue} ${random_number}
${string_list} Convert To String ${listValue}
${string_list} Remove String ${string_list} u
${string_list} Replace String ${string_list} ' "
${Rlist} Set Json Value ${Rlist} /list ${string_list}
Log Json ${Rlist}
Hope this helps.

A small question: i'm using JsonConverter from Github.
(https://github.com/VBA-tools/VBA-JSON/blob/master/JsonConverter.bas)
Code is working on most of the "GET" request.
Only when the same 'column' is accuring multiple times in the 'ResponseText' then it's not. (like "imei" in the example)
So I need a way to handle a long 'Responsetext' to fill multiple rows in an access db.
Dim Json As Object
Set Json = JsonConverter.ParseJson(xmlhttp.ResponseText)
MsgBox (Json("imei")) 'temp
Error 5: Invalid Procedure or Call Argument.
Any ideas?
Many thanks,
I can only provide a part of the answer, because I cannot recreate it, without the full JSON Response Text:
The response with mutliple values in JSON returns an Object of the type Collection. Hence you have to use a loop to iterate through all responses. Like this:
Dim Json As Object
Set Json = JsonConverter.ParseJson(xmlhttp.ResponseText)
For Each singleJsonItem In Json
'What object type is singleJsonItem? To find out, maybe use:
'MsgBox singleJsonItem("imei")
Next singleJsonItem
You have to find out the object type of the collectionentries to extract the JSON Entry.
Solved like this:
used : https://github.com/VBA-tools/VBA-JSON
and named the module: 'mdl_JsonConverter'
Set Json = mdl_JsonConverter.ParseJson(xmlhttp.ResponseText)
For Each item In Json
input_1 = item("input_1")
input_2 = item("input_2")
'THEN DO SOMETHING WITH VALUES F.E. ADDING THEM IN A TABLE
Next
If you responseText contains a searchRecords list then filter by searchRecords before for each
Set Json = JsonConverter.ParseJson(strResponse)
For Each singleJsonItem In Json("searchRecords")
'What object type is singleJsonItem? To find out, maybe use:
Msgbox singleJsonItem("Name")
Next singleJsonItem
So I have some json that looks like this, which I got after taking it out of some other json by doing response.body.to_json:
{\n \"access_token\": \"<some_access_token>\",\n \"token_type\": \"Bearer\",\n \"expires_in\": 3600,\n \"id_token\": \<some_token>\"\n}\n"
I want to pull out the access_token, so I do
to_return = {token: responseJson[:access_token]}
but this gives me a
TypeError: no implicit conversion of Symbol into Integer
Why? How do I get my access token out? Why are there random backslashes everywhere?
to_json doesn't parse JSON - it does the complete opposite: it turns a ruby object into a string containing the JSON representation of that object is.
It's not clear from your question what response.body is. It could be a string, or depending on your http library it might have already been parsed for you.
If the latter then
response.body["access_token"]
Will be your token, if the former then try
JSON.parse(response.body)["access_token"]
Use with double quotes when calling access_token. Like below:
to_return = {token: responseJson["access_token"]}
Or backslashes are escaped delimiters and make sure you first parse JSON.
I'm testing data lake for an application I am developing. I'm new to U-SQL and data lake and am just trying to query all records in a JSON file. Right now, It's only returning one record and I'm not sure why because the file has about 200.
My code is:
DECLARE #input string = #"/MSEStream/output/2016/08/12_0_fc829ede3c1d4cf9a3278d43e7e4e9d0.json";
REFERENCE ASSEMBLY [Newtonsoft.Json];
REFERENCE ASSEMBLY [Microsoft.Analytics.Samples.Formats];
#allposts =
EXTRACT
id string
FROM #input
USING new Microsoft.Analytics.Samples.Formats.Json.JsonExtractor();
#result =
SELECT *
FROM #allposts;
OUTPUT #result
TO "/ProcessedQueries/all_posts.csv"
USING Outputters.Csv();
Data Example:
{
"id":"398507",
"contenttype":"POST",
"posttype":"post",
"uri":"http://twitter.com/etc",
"title":null,
"profile":{
"#class":"PublisherV2_0",
"name":"Company",

"longitude":-31.432},
"quadKey":"000000000000000"},

"externalId":"00000000000"},
"source":{

"id":"18",
"param":"Twitter"},
"content":{
"text":"Description of post"},
"language":{
"name":"English",

}
}
Thank you for the help in advance
The JsonExtractor takes an argument that allows you to specify which items or objects are being mapped into rows using a JSON Path expression. If you don’t specify anything it will take the top root (which is one row).
You want every one of the items in the array, so you specify it as:
USING new Microsoft.Analytics.Samples.Formats.Json.JsonExtractor("[*]");
Where [*] is the JSON Path expression that says give me all the elements of the array which in this case is the top-level array.
If you have a JSON node in your field called id, your original script posted in the question would return the node with name "id" under the rootnode. To get all the nodes, your script will be structured as
#allposts =
EXTRACT
id string,
contenttype string,
posttype string,
uri string,
title string,
profile string
FROM #input
USING new Microsoft.Analytics.Samples.Formats.Json.JsonExtractor();
Please let us know if it works. The alternative would be to extract it using a native extractor to read it all in a string (as MRys mentioned, as long as your JSON is under 128 KB this would work).
#allposts =
EXTRACT
json string
FROM #input
USING Extractors.Text(delimiter:'\b', quoting:false);
i have a json object which contains json data with a key. now i want to extract value from that json object like name, address etc and store them to variables.
controller
json_arr = new JSONArray(j_str);
int count = json_arr.length();
json_o.put("user", json_arr);
j_str contains following data
[{"Bollywood":[{"actor":[{"name":"AA","gender":"Male"},{"name":"BB","gender":"Male"}]}]},{"Hollywood":[{"actor":[{"name":"CC","gender":"Male"},{"name":"DD","gender":"Male"}]}]}]
now it is converted to json object -- json_o ,, putting a key --- "user". now how can get a specific data such as 2nd actor name from hollywood. (i.e value DD). after then store that to a string.
Short answer: Use Jackson to map the json string to a java object, and then extract that value as a variable.
Here is a quick guide on doing this with jackson: http://www.mkyong.com/java/how-to-convert-java-object-to-from-json-jackson/
I have a Json file in which there is a field which I need to edit and save the file for next usage.
But the field which I need to edit is as shown below,
The value I need to assign fr the field is generated Randomly in run time which i'll be capturing in a variable and pass it to this json specific key "dp" then save the json.
The saved json will be used for REST POST url.
{
"p": "10",
"v": 100,
"vt": [
{
"dp": "Field to be edited"(integer value) ,
]
}
The simplest solution would be to write a python keyword that can change the value for you. However, you can solve this with robot keywords by performing the following steps:
convert the JSON string to a dictionary
modify the dictionary
convert the dictionary back to a JSON string
Convert the JSON string to a dictionary
Python has a module (json) for working with JSON data. You can use the evaluate keyword to convert your JSON string to a python dictionary using the loads (load string) method of that module.
Assuming your JSON data is in a robot variable named ${json_string}, you can convert it to a python dictionary like this:
${json}= evaluate json.loads('''${json_string}''') json
With the above, ${json} now holds a reference to a dictionary that contains all of the json data.
Modify the dictionary
The Collections library that comes with robot has a keyword named set to dictionary which can be used to set the value of a dictionary element. In this case, you need to change the value of a dictionary nested inside the vt element of the JSON object. We can reference that nested dictionary using robot's extended variable syntax.
For example:
set to dictionary ${json["vt"]} dp=the new value
With that, ${json} now has the new value. However, it is still a python dictionary rather than JSON data, so there's one more step.
Convert the dictionary back to JSON
Converting the dictionary back to JSON is the reverse of the first step. Namely, use the dumps (dump string) method of the json module:
${json_string}= evaluate json.dumps(${json}) json
With that, ${json_string} will contain a valid JSON string with the modified data.
Complete example
The following is a complete working example. The JSON string will be printed before and after the substitution of the new value:

Library Collections
*** Test Cases ***
Example
${json_string}= catenate
... {
... "p": "10",
... "v": 100,
... "vt": {
... "dp": "Field to be edited"
... }
... }
log to console \nOriginal JSON:\n${json_string}
${json}= evaluate json.loads('''${json_string}''') json
set to dictionary ${json["vt"]} dp=the new value
${json_string}= evaluate json.dumps(${json}) json
log to console \nNew JSON string:\n${json_string}
For reading and writing data to and from file I am using OperatingSystem library
${json} Get Binary File ${json_path}nameOfJsonFile.json
It works for me on API testing, to read .json and POST, like here
*** Settings ***
Library Collections
Library ExtendedRequestsLibrary
Library OperatingSystem
*** Variables ***
${uri} https://blabla.com/service/
${json_path} C:/home/user/project/src/json/
*** Test Cases ***
Robot Test Case
Create Session alias ${uri}
&{headers} Create Dictionary Content-Type=application/json; charset=utf-8
${json} Get Binary File ${json_path}nameOfJsonFile.json
${resp} Post Request alias data=${json} headers=${headers}
Should Be Equal As Strings ${resp.status_code} 200
For integer values in JSON, the other answers did not work for me.
This worked:
${json}= Catenate { "p": "10", "v": 100, "vt": { "dp": "Field to be edited" } }
${value} Set Variable 2 #the value you want
${value} Convert To Integer ${value}
${json}= Evaluate json.loads('''${json}''') json
Set To Dictionary ${json["vt"]} dp=${value}
${json}= Evaluate json.dumps(${json}) json
Log ${json}
Convert To Integer was required, otherwise the value is still in string "${value}"
