Remove escaped whitespace characters from JSON bodies, in request code generator

[JP-from-Postman]

[User feedback, submitted by Postman Support]

Please read through the guidelines before creating a new issue.

Describe the bug
For some languages, the Generate Code Snippets tool includes newlines (\n) and tabs (\t) for JSON request body strings. User feedback is that these may be superfluous, and can be omitted from code generation. See screenshot below:

To Reproduce
Steps to reproduce the behavior:

1. Create a new request
2. Add a JSON body, (example below)

3. Open Code Generator for request, select a language where \n and \t show up:

• C (LibCurl)
• C# (RestSharp)
• Go
• Java OK HTTP
• Java Unirest
• JavaScript Jquery AJAX
• (Others)

4. Find request body string in generated code, see \n and \b escaped characters

Expected behavior
Newline and tab characters for JSON body strings these languages could be omitted (?

App information (please complete the following information):

• App Type: Native
• Postman Version: 6.7.1
• OS: Linux, Mac, (guessing Windows as well)

Relatedly: in languages that have "heavy" or "raw" strings like Go (``), Rust (r#" "#), and Python (''' '''), prefer to use those strings, so as to reduce the escaped double quotes in the JSON body.

This is affecting our documentation through postman as well.

user reports this is an issue as well.

It looks like this is still affecting documentation. Since the bug is still open, can it be addressed here?

I have created two PRs to fix this issue in Javascript/Nodejs and Python codegens.
Use proper indentation for JSON bodies in Javascript and Nodejs codegens
Use json.dumps in Python codegens if Content-Type is JSON

Hey @JP-from-Postman @stcalica @ryparker @Lucretiel !!

We have made some fixes around unwanted characters in JS/Node and Python codegens as mentioned above. Could you please try the latest version postman app and see if you still face these issues?

[ariellevi]

Thank you the fixes are working grate , did you continue to another language like C#?

Hi, this problem is still happening in version 8.10.0.

JSON body content in C# code includes new line characters in the code snippet. If I change the code snippet from C# - RestSharp to cURL, then the JSON content will be formatted correctly, without new line characters. This also affects the Postman documentation examples.

I'm facing a similar indentation problem while writing my API documentation.

Is there any solution of it?
