http.post return 307 error code in flutter

Question

I am using http client for flutter network call.

1. My request working on postman getting response properly,
2. But while trying with http.post it returns error code 307-Temporary Redirect,

Method Body:

static Future<http.Response> httpPost(
  Map postParam, String serviceURL) async {
Map tempParam = {"id": "username", "pwd": "password"};
var param = json.encode(tempParam);
serviceURL = "http:xxxx/Login/Login";

// temp check
Map<String, String> headers = {
  'Content-Type': 'application/json',
  'cache-control': 'no-cache',
};
await http.post(serviceURL, headers: headers, body: param).then((response) {
  return response;
});
}

Also, the same code returns a proper response to other requests and URLs. First I trying with chopper client but had same issue.

I am unable to detect that issue from my end of from server-side.

Any help/hint will be helpful

Answer 1

Try to put a slash / at the end of the serviceUrl. So, serviceUrl is serviceURL = "http:xxxx/Login/Login/" instead of serviceURL = "http:xxxx/Login/Login".

This works for me.

Answer 2

You need to find a way to follow redirect.

Maybe postman is doing that.

Read this >> https://api.flutter.dev/flutter/dart-io/HttpClientRequest/followRedirects.html

Can you try with using get instead of post? At least to try and see what happend

In the documentation said:

Automatic redirect will only happen for "GET" and "HEAD" requests
only for the status codes 

HttpStatus.movedPermanently (301), 
HttpStatus.found (302), 
HttpStatus.movedTemporarily (302, alias for HttpStatus.found), 
HttpStatus.seeOther (303),
HttpStatus.temporaryRedirect (307)
