Hi there, in my project blueprint I’m trying to use Google Natural Language APIs but can’t find a way to serialize a correct json.
I need a json like this:
{
“document”: {
“type”: “PLAIN_TEXT”,
“language”: “it”,
“content”: “domanda da analizzare”
},
“encodingType”: “UTF8”
}
Where “content” is a string type variable in my blueprint.
How can I make this JSON using VaRest to send to to the service?
Thanks in advance
Danilo
Thanks for your help but “content” should be a variable.
I’m trying something here
But in print string i got the json like this:
{“document”:“{"type":"PLAIN_TEXT","language":"it","content":"ciao! oggi sono stato molto bene e sono molto contento"}”,“encodingType”:“UTF8”}
And it can’t read it properly.
Decode to json object creates the valid json object without the need for specific nesting
{
"document": {
"type": "PLAIN_TEXT",
"language": "it",
"content": "domanda da analizzare"
},
"encodingType": "UTF8"
}
The problem is probably with your double quotation marks. They are invalid.
You seem to have “ and ” instead of just "
Once the quotation marks are corrected it validates
Thanks for your answer but I don’t know how to change this because VaRest is doing all the job.
This is the full setup for this JSON i need:
In the first “Print String” node the string from “Encode JSON to single string” is:
{"type":"PLAIN_TEXT","language":"it","content":"ciao, oggi sono stato molto bene e sono molto contento"}
In the second “Print String” node the string from “Encode JSON to single string” is:
{"document":"{\"type\":\"PLAIN_TEXT\",\"language\":\"it\",\"content\":\"ciao, oggi sono stato molto bene e sono molto contento\"}","encodingType":"UTF8"}
The JSON should be like this:
{
"document": {
"type": "PLAIN_TEXT",
"language": "it",
"content": "ciao, oggi sono stato molto bene e sono molto contento"
},
"encodingType": "UTF8"
}
I tried other nodes and functions but nothing is changing something so I think the problem could be in “Encode JSON to single string” node, but I am not a pro so I really don’t know.
May there is another way to setup a JSON like this with VaRest but I don’t know about it.
I showed you how to get it working by using Decode Json Object. It takes the direct string and convets it to a json object that varest uses directly.
Just make sure the information in the literal string has the correct quotation marks.
It seems that is not working with “decote json object”.
I tryed to clean the string replacing "" with " " but even if in “print string” I see it correctly when I try to post it to google service there are "" in the string again.
I don’t know.
Maybe I placed “decode” in the wrong position idk.
Even if I clean the string like this:
Providing this string:
{"document":{ "type ": "PLAIN_TEXT ", "language ": "it ", "content ": "ciao, oggi sono stato molto bene e sono molto contento "},"encodingType":"UTF8"}
Google Natural Language response is:
LogVaRest: Request (json): POST https://language.googleapis.com/v1beta2/documents:analyzeSentiment?key=***** (check bExtendedLog for additional data)
LogVaRest: Response (400):
