我正在尝试向我们的后端服务器发出 POST 请求，但我不断收到 SocketTimeOutExceptions 或 HTTP 500 错误。它会在这两者之间随机切换（即使值相同）。
我已经尝试过的事情
- 出于某种原因添加 OkHttp 库（v2.4.0）我收到错误，尽管改造说它支持 v2.0.0+源，但它可能不受支持
- 实施
Callback<Account>到班级而不是这个，它也给了我比新版本更多的http500 - 对此，我添加了 UrlFactory 和 OkHttp 库并按照这些步骤操作，但随后整个应用程序崩溃（日志和更改）
下面是简化的代码
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;
}
}
