Retrofit中的SocketTimeoutException

Question

我试图向服务器POST请求获取数据,但有时它发生了SocketTimeoutException!

我曾经Ok3Client解决它,但我面临同样的例外如何解决它？

我的代码如下

public void getNormalLogin() {
        if (mProgressDialog == null) {
            mProgressDialog = ViewUtils.createProgressDialog(mActivity);
            mProgressDialog.show();
        } else {
            mProgressDialog.show();
        }

        if (Build.VERSION.SDK != null && Build.VERSION.SDK_INT > 13) {
            restadapter = new RestAdapter.Builder().setEndpoint(HOST).setLogLevel(RestAdapter.LogLevel.FULL).setClient(new Ok3Client(new OkHttpClient())).build();
            mApi = restadapter.create(Api.class);
            mApi.SignIn(etEmail.getText().toString(), etPassword.getText().toString(), new Callback<ArrayList<SignUpMainBean>>() {
                @Override
                public void success(ArrayList<SignUpMainBean> signUpMainBeen, Response response) {
                    mProgressDialog.dismiss();
                    LOGD("Status:: ::", String.valueOf(response.getStatus()));
                    LOGD("Code:: ::", String.valueOf(signUpMainBeen.get(0).getCode()));
                    if (signUpMainBeen != null && signUpMainBeen.size() > 0) {
                        if (signUpMainBeen.get(0).getCode() == 1) {

                            for (int i = 0; i < signUpMainBeen.size(); i++) {
                                for (int j = 0; j < signUpMainBeen.get(i).getResult().size(); j++) {
                                    showToast(mActivity, getString(R.string.you_have_successfully_login), Toast.LENGTH_SHORT);
                                    LOGD("Success", "Success");                                                                         
                                   finish();
                                    SignIn.mActivity.finish();
                                }
                            }

                        } else if (signUpMainBeen.get(0).getCode() == 0) {
                            mProgressDialog.dismiss();
                            showToast(mActivity, getString(R.string.invalid_email_password), Toast.LENGTH_SHORT);
                            LOGD("Invalid email or password", "Invalid email or password");
                        } else if (signUpMainBeen.get(0).getCode() == -1) {
                            mProgressDialog.dismiss();
                            showToast(mActivity, getString(R.string.your_account_is_inactive), Toast.LENGTH_SHORT);
                            LOGD("Your account is inactive", "Your account is inactive");
                        }
                    }
                }

                @Override
                public void failure(RetrofitError error) {
                    mProgressDialog.dismiss();
                    showToast(mActivity, getString(R.string.can_not_connect_to_server), Toast.LENGTH_SHORT);
                    LOGD("Failure", "Failure");
                }
            });
        }
    }

Answer 1

如果提取花费更多时间,请增加时间,使用它为我工作的代码

 OkHttpClient client = new OkHttpClient.Builder()
            .connectTimeout(100, TimeUnit.SECONDS)
            .readTimeout(100,TimeUnit.SECONDS).build();
    Retrofit retrofit = new Retrofit.Builder()
            .baseUrl("yourbaseurl").client(client)
            .addConverterFactory(GsonConverterFactory.create(new  Gson())).build();

干草这是不是最好的做法这个评论下来后端不应该这么长,用户必须通知错误或再试一次消息

预防SocketTimeoutException超出了我们的极限......有效处理它的一种方法是定义一个connection timeout

示例

改造1.9.0

restadapter = new RestAdapter.Builder().setEndpoint(HOST).setLogLevel(RestAdapter.LogLevel.FULL).setClient(new OkHttpClient()
                .setReadTimeout(30, TimeUnit.SECONDS)
                .setConnectTimeout(30, TimeUnit.SECONDS)).build();

改造2.0.0

OkHttpClient client = new OkHttpClient();
client.setConnectTimeout(10, TimeUnit.SECONDS);
client.setReadTimeout(30, TimeUnit.SECONDS);
retrofit = new Retrofit.Builder()
        .baseUrl(BASE_URL)
        .addConverterFactory(GsonConverterFactory.create())
        .client(client)
        .build();

改造2.4.0

// setting custom timeouts
    OkHttpClient.Builder client = new Builder();
    client.connectTimeout(15, TimeUnit.SECONDS);
    client.readTimeout(15, TimeUnit.SECONDS);
    client.writeTimeout(15, TimeUnit.SECONDS);

    if (retrofit == null) {
      retrofit = new Retrofit.Builder()
          .baseUrl(BASE_URL)
          .addConverterFactory(GsonConverterFactory.create())
          .client(client.build())
          .build();
    }
    return retrofit;
  }

Answer 3

我在某些请求中遇到了同样的问题。通常在有活动请求并且SocketTimeoutException由于与网络断开连接而得到时得到这个。之后，相同的请求总是抛出SocketTimeoutException。

我OkHttpClient按照“ java.net.SocketTimeoutException from HTTP/2 connection leave dead okhttp clients in pool ”中的建议使用下面的代码构建了我的代码：

val builder = OkHttpClient.Builder()
    .cache(cache)
    .readTimeout(READ_TIMEOUT, TimeUnit.SECONDS)
    .connectTimeout(CONNECT_TIMEOUT, TimeUnit.SECONDS)
    .connectionPool(ConnectionPool(0, 5, TimeUnit.MINUTES))
    .protocols(listOf(Protocol.HTTP_1_1))

设置connectionPool和protocols将修复SocketTimeoutException由超时引起的。

这是一个临时修复，希望能在OkHttpused by 的未来版本中得到解决Retrofit。
