UnityWebRequest.Post(url, jsonData) sending broken Json

@Sir-Gatlin I tried this exact code it's sending the request to the server. But the post is empty and has no files? Any idea what's causing this? This is my stackoverflow post https://stackoverflow.com/questions/58486388/unity3d-post-is-empty-when-doing-a-unitywebrequest

 

ok code runs perfectly in Windows but when i use it in android apk i get error Bad Request again.put is not working as well. any idea to fix this bug?
version: 2019.1.9f1
android version 7.0

 

It has already sometime I don't use the POST method in my projects, but I know that Unity changed a little bit the UnityWebRequest and added a new method only for Post. Here you are the Documentation about it:
https://docs.unity3d.com/ScriptReference/Networking.UnityWebRequest.Post.html

 

Happy it was useful.

 

Hello,
I don’t use UnityWebRequest for call rest, I use the classic c# implemetation (HttpClient) who works fine, you need to choose Net Standard for use it.

 

hi.sorry for late response.
i installed unity 2019.2.10f1 and its working.thank you

 

For those of you looking to offload the boilerplate of a C# solution. You can just force Unity to send utf-8 escaped data by setting the content-type to application/nothing (which is nonsense), then on the javascript backend decode it to JSON. Code below.

Client: Minimal boilerplate, could even wrap
UnityWebRequest www = UnityWebRequest.Post(path, jsonString);
www.uploadHandler.contentType = "application/nothing";

Backend: In some express middlware
var decode_utf8 = function decode_utf8(s) {
return decodeURIComponent(unescape(s));
};

req.body = decode_utf8(req.body);
req.body = JSON.parse(req.body);
return next();

 

Working Perfectly to mine alos man. thank you

 

Nice to know it worked.
It has already some time I don't use the POST method in my projects, but I know that Unity changed a little bit the UnityWebRequest and added a new method only for Post. Here you are the Documentation about it:

You saved me the life again. 5 years later haha Thank you. (this is the second time you saved me)

 

Hello from the year 2021 The UnityWebRequest.Post with JSON data still doesn't work. This answer with small alterations does. Thank you!

Code (CSharp):

1. using var postRequest = new UnityWebRequest();
2.         postRequest.url = PostUri; // PostUri is a string containing the url
3.         postRequest.method = "POST";
4.         postRequest.uploadHandler = new UploadHandlerRaw(Encoding.UTF8.GetBytes(postData)); // postData is Json file as a string
5.         postRequest.downloadHandler = new DownloadHandlerBuffer();
6.         postRequest.SetRequestHeader("Content-Type", "application/json");
7.         postRequest.SendWebRequest();
