如何使用JWT令牌从android中的cookie存储发送HTTP请求

Question

到目前为止我做了什么:

我正在尝试与具有自定义身份验证的Java Web应用程序进行通信.在那里,我需要首先点击一个带有请求体参数JSON类型的链接,以便在我的cookie中获取JWT auth-token.

我在Postman测试了连接,我收到了正确的JSON回复.但是当我在我的Android应用程序中尝试相同时它返回Bad Request错误.

对邮差测试:

登录和进入auth-tokencookie存储:

• 发布,网址: http://iitjeeacademy.com/iitjeeacademy/api/v1/login
• 头: Content-Type:application/json
• 请求正文(原始): {"password":"123","type":"student","email":"shobhit@gmail.com"}

登录后获取响应使用:

以下是我HttpURLConnection在android中的请求代码:

"Post"方法,此连接用于获取auth-token.此方法返回200 Response.

HttpURLConnection connection = null;
try {
        // Created URL for connection.
        URL url = new URL(link);

        // Input data setup
        byte[] postData = request.getBytes(StandardCharsets.UTF_8);
        int postDataLength = postData.length;

        // Created connection
        connection = (HttpURLConnection) url.openConnection();
        connection.setDoOutput(true);
        connection.setInstanceFollowRedirects(false);
        connection.setRequestMethod("POST");
        connection.setRequestProperty("Content-Type", "application/json");
        connection.setRequestProperty("charset", "utf-8");
        connection.setRequestProperty("Content-Length", Integer.toString(postDataLength));
        connection.setUseCaches(false);

        // loaded inputs
        DataOutputStream wr = new DataOutputStream(connection.getOutputStream());
        wr.write(postData);
        wr.flush();
        wr.close();

        // getting a response
        int responseCode = connection.getResponseCode();
        if (responseCode == HttpURLConnection.HTTP_OK){
            // Read response
            response = convertToString(connection.getInputStream());
            return response;
        }else{
            // Read Error
            String response = connection.getResponseMessage();
            return response;
        }
    } catch (MalformedURLException e) {
        e.printStackTrace();
        Log.v("MalformedURL ---> ", e.getMessage());
    } catch (ProtocolException p) {
        p.printStackTrace();
        Log.v("Connection ---> ", p.getMessage());
    } catch (IOException i) {
        i.printStackTrace();
        Log.v("IO Exception ---> ", i.getMessage());
    } finally {
        connection.disconnect();
    }

"获取"方法,必须auth-token在会话cookie中获得响应.此方法提供401 Unauthorized Error.

HttpURLConnection connection = null;
try{
        // Created URL for connection
        URL url = new URL(link);

        // Created connection
        connection = (HttpURLConnection) url.openConnection();
        connection.setInstanceFollowRedirects(false);
        connection.setRequestMethod("GET");
        connection.setRequestProperty("Content-Type", "application/json");
        connection.setRequestProperty("charset", "utf-8");

        // getting a response
        int responseCode = connection.getResponseCode();
        if (responseCode == HttpURLConnection.HTTP_OK){
            response = convertToString(connection.getInputStream());
            return response;
        }else{
            // Read Error
            String response = connection.getResponseMessage();
            return response;
        }
    } catch (MalformedURLException e) {
        e.printStackTrace();
    } catch (ProtocolException p) {
        p.printStackTrace();
    } catch (IOException i) {
        i.printStackTrace();
    } finally {
        connection.disconnect();
    }

问题: 如何在HttpURLConnectionandroid中使用存储的JWT Token 来获取Web服务的响应.

Answer 1

我相信你已经继续前进,但......

对于JWT auth,我将发送一个HTTP Request 标头格式为:

授权: Bearer jwtHeader.jwtPayload.jwtSignature

例:

Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiYWRtaW4iOnRydWV9.TJVA95OrM7E2cBab30RMHrHDcEfxjoYZgeFONFh7HgQ
