我正在尝试向后端服务器发出POST请求，但我一直收到SocketTimeOutExceptions或HTTP 500错误。 并且它随机地在这两个之间切换（即使具有相同的值）。
我已经尝试过的事情
Callback<Account>实施到班级而不是this，它还给了我比新版本更多的http500 以下是简单的代码
登入
public class SignIn extends Activity implements Callback<Account>{
private static final String TAG = "SignIn";
private ImageButton sign_in_backBtn;
private TextView sign_in_make_account;
private Button btn_SignIn;
private EditText email;
private EditText password;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.sign_in);
btn_SignIn = (Button) findViewById(R.id.sign_in_btnSignIn);
email = (EditText)findViewById(R.id.sign_in_email);
password = (EditText)findViewById(R.id.sign_in_password);
initListers();
}
private void initListers() {
btn_SignIn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String emailAdres = email.getText().toString();
String passWord = password .getText().toString();
if(emailAdresValidate == true && passWordValidate == true){
Account account = new Account(passWord,emailAdres);
login(account);
}
}
});
}
private void login(Account account){
JppApplication.getService().logIn(account,this);
}
@Override
public void success(Account account, Response response) {
Log.d(TAG,response.toString());
Log.d(TAG, "login success");
}
@Override
public void failure(RetrofitError retrofitError) {
Log.e(TAG,retrofitError.getKind().toString());
Log.d(TAG, "login failed");
}
}
服务
public interface Service {
@POST("/accounts/login")
void logIn(@Body Account account,Callback<Account> created);
}
帐户
public class Account {
@SerializedName("Email")
private String email;
@SerializedName("Password")
private String paswoord;
public Account(String paswoord, String email) {
this.paswoord = paswoord;
this.email = email;
}
}

答案 0 :(得分：0)
好的，所以证明错误是由于以下原因。我们学校使用了运行服务器的廉价VPN。我总是通过在物理设备上运行和调试它来测试这个应用程序，而不是在模拟器上运行它。
您必须使用VPN的应用程序才能连接到服务器，由于某种原因连接经常停止，因此每当我们遇到超时异常时，我们只需通过应用程序重新启动VPN连接我们肯定不会在大约一分钟左右收到任何超时异常。
这是学校在各处削减预算时所得到的。
当然，HTTP-500是因为我们的代码中出现了错误：）
