在 http-POST 上改造 SocketTimeoutException（and/or http 500 错误）
Retrofit SocketTimeoutException (and/or http 500 error) on http-POST
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。
它不断地在这两个之间随机切换（即使具有相同的值）。
我已经尝试过的东西
- 添加 OkHttp 库 (v2.4.0) 出于某种原因我得到了它可能不受支持的错误，尽管改造说它支持 v2.0.0+ source
- 将
Callback<Account> 实施到 class 而不是 this，它还给了我比新版本更多的 http500
- this, I've added the UrlFactory and OkHttp libraries and followed these steps but then the entire app crashes (log & changes)
下面是简单的代码
登录
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);
}
账户
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;
}
}
可能log/error我得到

好的，原来错误是由于以下原因造成的。我们学校使用的是服务器 运行 上的廉价 VPN。我总是通过 运行 测试这个应用程序并在物理设备上调试它而不是 运行 在模拟器上调试它。
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，连接经常断开，所以每当我们遇到超时异常时，我们只需要通过应用程序重新启动 VPN 连接，然后我们我们确定在大约一分钟左右的时间内没有收到任何超时异常。
这就是当学校试图到处削减预算时你得到的结果..
当然，HTTP-500 显然是因为我们的代码中存在错误:)
