http - 颤动 http.post 给出 500 错误，而 api 在邮递员中工作正常

问题描述

此登录 API 在邮递员中运行良好，但我在颤振中收到500状态代码错误。

以下是调用 api 的服务代码：

import 'dart:convert';
import 'package:http/http.dart' as http;
...

class AuthService {
  static const API_URL =
      "http://ec2-15-185-73-129.me-south-1.compute.amazonaws.com";
  static const headers = {
    'Content-Type': 'application/json'
  };
  Future<APIResponse<AuthResponse>> signIn() async {
    var body = jsonEncode({"username": "username", "password": "password"});
    var response =
        await http.post(API_URL + "/api-token-auth", headers: headers, body: body)));
    print(response.body.toString());
    print(response.request.toString());
    if (response.statusCode == 200) {
      // not reaching here
    } else {
      print(handleError(response.statusCode));
      // response.statusCode is **500**

    }
  }
}

print(response.body.toString()) 给出以下输出：

print(response.request.toString()) 给出以下输出：

POST http://ec2-15-185-73-129.me-south-1.compute.amazonaws.com/api-token-auth

请帮忙 邮递员请求输出

标签： httpflutter

解决方案

替换网址：

API_URL + "/api-token-auth"

和

API_URL + "/api-token-auth/"

它有点奇怪。您的服务器端路由可能有问题，但尾随/其工作。
