如何在Retrofit-2.0 + android中设置超时

Question

我提到了这个链接,但我似乎无法为我实施

我在用

 compile 'com.squareup.retrofit2:retrofit:2.0.2'
 compile 'com.squareup.retrofit2:converter-gson:2.0.2'

我使用下面的代码,如何为此设置超时!

public class ApiClient {

    public static final String BASE_URL = Constants.BaseURL;
    private static Retrofit retrofit = null;

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

Answer 1

配置OkHttpClient以获取超时选项.然后使用它作为客户端Retrofit.Builder.

final OkHttpClient okHttpClient = new OkHttpClient.Builder()
    .connectTimeout(20, TimeUnit.SECONDS)
    .writeTimeout(20, TimeUnit.SECONDS)
    .readTimeout(30, TimeUnit.SECONDS)
    .build();

将此okHttpClient用于Retrofit#Builder

Retrofit.Builder()
    .client(okHttpClient);

有关超时的官方OkHttp文档就在这里

Answer 2

尝试下面的代码,它timeout是20秒,readTimeout是30秒

 private OkHttpClient getRequestHeader() {
        OkHttpClient httpClient = new OkHttpClient();
        httpClient.setConnectTimeout(20, TimeUnit.SECONDS);
        httpClient.setReadTimeout(30, TimeUnit.SECONDS);

        return httpClient;
    }

然后

public class ApiClient {

    public static final String BASE_URL = Constants.BaseURL;
    private static Retrofit retrofit = null;

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