In Postman, I use {{$randomUUID}} as a parameter, but I need to pass it as string (text) in the request. However, there is no convert function in Postman and I could not found any proper way to convert this generated UUID to string. So, how can I convert it to string in Postman and pass it as string?
I also tried something like "menuId": {{"" + $randomUUID}},, but is does not work.
{
"menuId": "{{$randomUUID}}"
}
you just have to enclose it with double quotes
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 have the following string:
"{\"headers\":[\"CNPJ\",\"PDF\",\"error\"],\"rows\":[[\"17192451000170\",\"FILE:application/pdf;170286;\",null],[\"234566767544\",\"FILE:application/pdf;456378;\",null],[\"233456767544\",\"FILE:application/pdf;456378;\",null]]}"
how do I parse it to a normal Json format?
meaning:
{"rows" :[
{"CNPJ":"17192451000170","PDF":"FILE:application/pdf;170286;","error":null},
{"CNPJ":"17192451000170","PDF":"FILE:application/pdf;170286;","error":null},
{"CNPJ":"17192451000170", "PDF":"FILE:application/pdf;170286;,"error":null"}
]}
or any other json format
This is already a valid JSON format.
If you just want to strip \ then you can simply:
(hbd#crayon2.yoonka.com)31> JsonOrg = <<"{\"headers\":[\"CNPJ\",\"PDF\",\"error\"],\"rows\":[[\"17192451000170\",\"FILE:application/pdf;170286;\",null],[\"234566767544\",\"FILE:application/pdf;456378;\",null],[\"233456767544\",\"FILE:application/pdf;456378;\",null]]}">>.
<<"{\"headers\":[\"CNPJ\",\"PDF\",\"error\"],\"rows\":[[\"17192451000170\",\"FILE:application/pdf;170286;\",null],[\"234566767544\",\"FI"...>>
(hbd#crayon2.yoonka.com)32> io:format("~s~n", [binary_to_list(JsonOrg)]).
{"headers":["CNPJ","PDF","error"],"rows":[["17192451000170","FILE:application/pdf;170286;",null],["234566767544","FILE:application/pdf;456378;",null],["233456767544","FILE:application/pdf;456378;",null]]}
ok
You can also parse back and forth between Json and Erlang. I tested that with the yajler decoder:
(hbd#crayon2.yoonka.com)43> {ok, Parsed} = yajler:decode(<<"{\"headers\":[\"CNPJ\",\"PDF\",\"error\"],\"rows\":[[\"17192451000170\",\"FILE:application/pdf;170286;\",null],[\"234566767544\",\"FILE:application/pdf;456378;\",null],[\"233456767544\",\"FILE:application/pdf;456378;\",null]]}">>).
{ok,[{<<"headers">>,[<<"CNPJ">>,<<"PDF">>,<<"error">>]},
{<<"rows">>,
[[<<"17192451000170">>,<<"FILE:application/pdf;170286;">>,
undefined],
[<<"234566767544">>,<<"FILE:application/pdf;456378;">>,
undefined],
[<<"233456767544">>,<<"FILE:application/pdf;456378;">>,
undefined]]}]}
(hbd#crayon2.yoonka.com)44> Json = binary:list_to_bin(yajler:encode(Parsed)).
<<"{\"headers\":[\"CNPJ\",\"PDF\",\"error\"],\"rows\":[[\"17192451000170\",\"FILE:application/pdf;170286;\",\"undefined\"],[\"2345667675"...>>
Yajler is an Erlang NIF so it is using a C library, in this case called yajl, to do the actual parsing, but I imagine a similar result you would get from other Erlang applications that can parse JSON.
I've 2 json feeds in payload (using Gather), i planned on using a groovy script to make it into a single json (I expected something like:
{key:value}{key:value})
<scripting:transformer doc:name="Groovy">
<scripting:script engine="Groovy"><![CDATA[return '{"data":['+payload.toString().replace("}{","},{"+']}']]></scripting:script>
</scripting:transformer>
(expected output: {"data":[{key:value},{key:value}]}
But i get:
{"data":[[org.glassfish.grizzly.utils.BufferInputStream#102e37e, org.glassfish.grizzly.utils.BufferInputStream#a569d1]]}
W/O groovy script:
[org.glassfish.grizzly.utils.BufferInputStream#102e37e, org.glassfish.grizzly.utils.BufferInputStream#a569d1]
an array of inputstream
I tried using byte array to string, and object to string but it doesnt work, I dont figure out how can i solve this
Replace:
payload.toString().replace("}{","},{")
with:
payload.collect { it.text }.join(',')
Explanation: .text deserializes an input stream to a string, so payload.collect { it.text } will yield a collection of strings. Then join(',') takes care of concatenating these strings, separating them with ,
How can I convert string with format like:
{Param1: "Value", Param2: "value2", Param3: "value3"}
to JSON string for my Post query?
Thanks in advance.
This is already a JSON string just send it appended with the headers.
If you need to access these values, then you need to use something like swiftyJSON or JSONswift.
What you have posted appears to be a JSON string containing a dictionary.
