我是 Java 和 Android 编程的新手,我试图在我的服务器上获取 PHP 文件的结果,但出现以下异常:
java.net.ProtocolException: Unexpected status line: <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">

这是异常来自的代码(在LoginActivity.java中):
Thread loginCheckThread = new Thread(new Runnable() {
public void run() {
String result = "", dataObj = "";
TextView username = (TextView) findViewById(R.id.login_mail);
TextView password = (TextView) findViewById(R.id.login_password);
JSONObject jsonObj = new JSONObject();
try {
jsonObj.put("loginMail", username.getText());
jsonObj.put("loginPassword", password.getText());
dataObj = jsonObj.toString(0);
} catch (JSONException e) {
e.printStackTrace();
}
try {
URL url = new URL("http://myserver.it/testandroid.php?data=" + dataObj);
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
try {
/* line #49 */ InputStream in = new BufferedInputStream(urlConnection.getInputStream());
ByteArrayOutputStream bo = new ByteArrayOutputStream();
int i = in.read();
while (i != -1) {
bo.write(i);
i = in.read();
}
result = bo.toString();
} catch (IOException e) {
result = "Exception: Class::IOStream Related";
e.printStackTrace();
} finally {
urlConnection.disconnect();
}
} catch (IOException e) {
result = "Exception: Class::URL Related";
}
System.out.println(result);
}
});
loginCheckThread.start();
导致异常的行是第#49行:
InputStream in = new BufferedInputStream(urlConnection.getInputStream());
PHP 文件现在只是一个测试文件,应该返回<input_username> - <input_password>
从data
查询字符串中的变量检索到的结果:
$jsonObj = json_decode($_GET["data"], TRUE);
echo $jsonObj["loginMail"] . " - " . $jsonObj["loginPassword"];
这个问题阻止了我大约两天,我该怎么做才能解决这个问题?
