我使用以下代码发送REST请求,请求失败(401错误),因为它需要用户名和密码。
如何将它们添加到网址?即使我在浏览器中复制网址并在其末尾添加用户名和密码,浏览器也会弹出登录页面,所以我想在代码中我应该添加用户名和密码参数但是如何?
URL url = new URL("www.example.com/user?ID=1234");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setDoOutput(true);
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type", "application/json");
if (conn.getResponseCode() != HttpURLConnection.HTTP_CREATED) {
throw new RuntimeException("Failed : HTTP error code : "
+ conn.getResponseCode());
}
我在代码中添加了以下内容,但仍然遇到401错误。
conn.setRequestProperty("username", "myusername");
conn.setRequestProperty("password", "mypassword");
答案 0 :(得分:1)
试试这个:
String params="username=myusername&password=mypassword";
conn.getOutputStream().write(params.getBytes());
conn.getOutputStream().flush();
conn.getOutputStream().close();
或许你需要编码params:
DataOutputStream dos = new DataOutputStream(conn.getOutputStream());
String postContent = URLEncoder.encode("username", "UTF-8") + "=" +
URLEncoder.encode(myusername, "UTF-8") + "&" +
URLEncoder.encode("password", "UTF-8") + "=" +
URLEncoder.encode(mypassword, "UTF-8") ;
dos.write(postContent.getBytes());
dos.flush();
dos.close();
String userPassword = username + ":" + password;
String encoding = new sun.misc.BASE64Encoder().encode(userPassword.getBytes());
URLConnection uc = url.openConnection();
uc.setRequestProperty("Authorization", "Basic " + encoding);
uc.connect();
