flutter 中的未授权即使我通过了授权令牌

Question

我有登录屏幕，它将包含几个字段并返回响应。

login

  login(String phn, String password) async {
    final prefs = await SharedPreferences.getInstance();
    await getLocation();
    String uri = "$baseUrl/User_Login";
    try {
      http.Response response = await http.post(Uri.parse(uri), headers: {
        'Accept': 'application/json'
      }, body: {
        "number": phn,
        "password": password,
        "long": long,
        "lati": lati
      });
      prefs.setString('cookie', response.headers['set-cookie']!);
      return json.decode(response.body);
    } catch (e) {
      return e;
    }
  }

它会回来

{status: success, Login_Key: f1278a9e15f48866beaeae2503f9b6d4, SESSION_ID: w00mRWDkIpGpz46WrilQ9mhRDyFEon8i0Zuqo89O}

在主页中我正在获取数据

 getData() async {
    final prefs = await SharedPreferences.getInstance();
    String cookie = prefs.getString('cookie').toString();
    String key = prefs.getString('authKey').toString(); // Login_key
    String session = prefs.getString('sessionKey').toString(); // SESSION_KEY
    String uri = "$baseUrlUser/user_bal";
    var headers = {
      'Accept': 'application/json',
      'Authorization': 'Bearer $key',
      'Cookie': cookie,
      // 'Token': session,
    };
    print(headers); // shown
    try {
      http.Response response = await http.get(Uri.parse(uri), headers: headers);
      return response.body;
    } catch (e) {
      return e;
    }
  }

甚至在那之后getdata正在返回对登录页面的响应。 它在 Postman 中运行良好，这就是print(Headers)的作用：

{Accept: application/json, Authorization: Bearer f1278a9e15f48866beaeae2503f9b6d4, Cookie: XSRF-TOKEN=eyJpdiI6ImZKRnJnZ090a3ZDUWw0UHhrbUpudXc9PSIsInZhbHVlIjoiNUFWVXNteFRqRE5FWjRRK3luN0xQNWpDa2FtRW5yN2dBRitSeDRaSkZzaGJsN29yZ0swcitSNFR2eWFVM1o3a044UTdFajg0a3NFSzdRbWFuc09qSXl5aFJiOXk4UzR0RTEraVd2THA2YytmRGVxVldla0JFdWhjWGdjVkpaeGwiLCJtYWMiOiI5YzFjZWM2YzBjMzk5ZWUyMjM5MjAzMWZmYTE4ZDY3MTBiMzMwMzU4MzY5MGVhODU5MzllNGIwZDQ1ODRjZTdmIiwidGFnIjoiIn0%3D; expires=Tue, 02-Aug-2022 12:14:43 GMT; Max-Age=7200; path=/; samesite=lax,laravel_session=eyJpdiI6ImhabnFOb0VHbzdCU0ExdzFHSis2UHc9PSIsInZhbHVlIjoiS0dXdTlZenQxVEdVTTd1NzRXdnE3UjBLSitKY1IrVE5FU2FvSXpxSEx2ZzBxVnJZRWhpbUx0UGZ0bklHVExiK3VDVVlSUFFHd3h6aUZQaWYybUg5RG45b0kzKzJmSEFFTERYajVXWUYycU1nWnVOa25zWnVGU0hhSzVPZXhzakYiLCJtYWMiOiJhN2VkZmUzZmIyMWQ4Zjg5MGMyY2MyMmY5ZTc3ZjhhZDhmMGVmYmJlMTkzMGZjZjBmMmFkMmFkY2NkOTNhN2QyIiwidGFnIjoiIn0%3D; path=/; httponly; samesite=lax}

Answer 1

要调试 API 响应，您首先需要知道服务器返回的内容。

步骤1

使用下面添加的行打印错误

try {
      http.Response response = await http.get(Uri.parse(uri), headers: headers);
      return response.body;
    } catch (e) {
      print(e); // add this and update your question
      return e;
    }
  }

第2步

检查 URL String uri = "$baseUrlUser/user_bal"; ，在您的 Postman 中，正确的 URL 是User_Bal （可能区分大小写）

Answer 2

在您的 header 中，您得到的是Cookie而不是set-cookie ，因此您的代码应该是。

prefs.setString('cookie', response.headers['Cookie']!);
