【问题描述】:
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 应用程序通信。在那,我需要先点击一个带有请求正文参数JSON类型的链接,以在我的cookie中获取JWTauth-token。
我已经在Postman 中测试了连接,我收到了正确的JSON 响应。但是当我在我的 android 应用程序中尝试相同时,它会返回 Bad Request 错误。
对于 Postman 测试:
用于登录并在 cookie 存储中获取 auth-token:
- 发帖,网址:
http://iitjeeacademy.com/iitjeeacademy/api/v1/login - 标题:
Content-Type:application/json - 请求正文(原始):
{"password":"123","type":"student","email":"shobhit@gmail.com"}
登录后使用:
- 获取,网址:
http://iitjeeacademy.com/iitjeeacademy/api/v1/student/me
以下是我在 android 中的HttpURLConnection 请求代码:
“Post”方法,此连接用于获取auth-token。 此方法返回 200 响应。
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,会话 cookie 中必须有 auth-token 才能获得响应。 此方法会产生 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:
如何使用HttpURLConnectionandroid中cookies中存储的JWT Token来获取Web服务的响应。
