如何在 Retrofit 库中设置超时?

How to set timeout in Retrofit library?

我在我的应用程序中使用 Retrofit 库,我想将超时设置为 60 秒。 Retrofit 有办法做到这一点吗?

我是这样设置Retrofit的:

RestAdapter restAdapter = new RestAdapter.Builder()
    .setServer(BuildConfig.BASE_URL)
    .setConverter(new GsonConverter(gson))
    .build();

如何设置超时?

您可以在底层 HTTP 客户端上设置超时。如果您不指定客户端,Retrofit 将创建一个具有默认连接和读取超时的客户端。要设置自己的超时,您需要配置自己的客户端并将其提供给 RestAdapter.Builder.

一个选项是使用同样来自 Square 的 OkHttp 客户端。

1.添加库依赖

在 build.gradle 中包含此行:

compile 'com.squareup.okhttp:okhttp:x.x.x'

其中 x.x.x 是所需的库版本。

2。设置客户端

例如,如果你想设置 60 秒的超时,对版本 2 之前的 Retrofit 和版本 3 之前的 Okhttp 这样做(对于较新的版本,请参见编辑):

public RestAdapter providesRestAdapter(Gson gson) {
    final OkHttpClient okHttpClient = new OkHttpClient();
    okHttpClient.setReadTimeout(60, TimeUnit.SECONDS);
    okHttpClient.setConnectTimeout(60, TimeUnit.SECONDS);

    return new RestAdapter.Builder()
        .setEndpoint(BuildConfig.BASE_URL)
        .setConverter(new GsonConverter(gson))
        .setClient(new OkClient(okHttpClient))
        .build();
}

编辑 1

对于自 3.x.x 以来的 okhttp 版本,您必须以这种方式设置依赖关系:

compile 'com.squareup.okhttp3:okhttp:x.x.x'

并使用构建器模式设置客户端:

final OkHttpClient okHttpClient = new OkHttpClient.Builder()
        .readTimeout(60, TimeUnit.SECONDS)
        .connectTimeout(60, TimeUnit.SECONDS)
        .build();

Retrofit 版本因为 2.x.x 也使用构建器模式,所以将上面的 return 块更改为:

return new Retrofit.Builder()
    .baseUrl(BuildConfig.BASE_URL)
    .addConverterFactory(GsonConverterFactory.create())
    .client(okHttpClient)
    .build();

如果使用像我的 providesRestAdapter 方法这样的代码,则将方法 return 类型更改为 Retrofit

Retrofit 2 中的更多信息 — 从 1.9 升级指南


ps:如果你的minSdkVersion大于8,可以使用TimeUnit.MINUTES:

okHttpClient.setReadTimeout(1, TimeUnit.MINUTES);
okHttpClient.setConnectTimeout(1, TimeUnit.MINUTES);

有关单位的更多详细信息,请参阅 TimeUnit

我正在使用 Retrofit 1.9 来获得 XML.

public class ServicioConexionRetrofitXML {

    public static final String API_BASE_URL = new GestorPreferencias().getPreferencias().getHost();
    public static final long tiempoMaximoRespuestaSegundos = 60;
    public static final long tiempoMaximoLecturaSegundos = 100;
    public static final OkHttpClient clienteOkHttp = new OkHttpClient();


    private static RestAdapter.Builder builder = new RestAdapter.Builder().
            setEndpoint(API_BASE_URL).
            setClient(new OkClient(clienteOkHttp)).setConverter(new SimpleXMLConverter());


    public static <S> S createService(Class<S> serviceClass) {
        clienteOkHttp.setConnectTimeout(tiempoMaximoRespuestaSegundos, TimeUnit.SECONDS);
        clienteOkHttp.setReadTimeout(tiempoMaximoLecturaSegundos, TimeUnit.SECONDS);
        RestAdapter adapter = builder.build();
        return adapter.create(serviceClass);
    }

}

如果您使用的是 Retrofit 1.9.0 和 okhttp 2.6.0,请添加到您的 Gradle 文件。

    compile 'com.squareup.retrofit:retrofit:1.9.0'
    compile 'com.squareup.okhttp:okhttp:2.6.0'
    // Librería de retrofit para XML converter (Simple) Se excluyen grupos para que no entre
    // en conflicto.
    compile('com.squareup.retrofit:converter-simplexml:1.9.0') {
        exclude group: 'xpp3', module: 'xpp3'
        exclude group: 'stax', module: 'stax-api'
        exclude group: 'stax', module: 'stax'
    }

注意:如果您需要获取 JSON,只需从上面的代码中删除即可。

.setConverter(new SimpleXMLConverter())

这些答案对我来说已经过时了,所以结果是这样的。

添加OkHttp,我的版本是3.3.1:

compile 'com.squareup.okhttp3:okhttp:3.3.1'

然后在构建 Retrofit 之前,执行以下操作:

OkHttpClient okHttpClient = new OkHttpClient().newBuilder()
    .connectTimeout(60, TimeUnit.SECONDS)
    .readTimeout(60, TimeUnit.SECONDS)
    .writeTimeout(60, TimeUnit.SECONDS)
    .build();
return new Retrofit.Builder()
    .baseUrl(baseUrl)
    .client(okHttpClient)
    .addConverterFactory(GsonConverterFactory.create())
    .build();
public class ApiModule {
    public WebService apiService(Context context) {
        String mBaseUrl = context.getString(BuildConfig.DEBUG ? R.string.local_url : R.string.live_url);

        HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor();
        loggingInterceptor.setLevel(BuildConfig.DEBUG ? HttpLoggingInterceptor.Level.BODY : HttpLoggingInterceptor.Level.NONE);

        OkHttpClient okHttpClient = new OkHttpClient.Builder()
                .readTimeout(120, TimeUnit.SECONDS)
                .writeTimeout(120, TimeUnit.SECONDS)
                .connectTimeout(120, TimeUnit.SECONDS)
                .addInterceptor(loggingInterceptor)
                //.addNetworkInterceptor(networkInterceptor)
                .build();

        return new Retrofit.Builder().baseUrl(mBaseUrl)
                .client(okHttpClient)
                .addConverterFactory(GsonConverterFactory.create())
                .addCallAdapterFactory(RxJavaCallAdapterFactory.create())
                .build().create(WebService.class);

    }
}

这将是为每个服务设置超时的最佳方法(将超时作为参数传递)

public static Retrofit getClient(String baseUrl, int serviceTimeout) {
        Retrofit retrofitselected = baseUrl.contains("http:") ? retrofit : retrofithttps;
        if (retrofitselected == null || retrofitselected.equals(retrofithttps)) {
            retrofitselected = new Retrofit.Builder()
                    .baseUrl(baseUrl)
                    .addConverterFactory(GsonConverterFactory.create(getGson().create()))
                    .client(!BuildConfig.FLAVOR.equals("PRE") ? new OkHttpClient.Builder()
                            .addInterceptor(new ResponseInterceptor())
                            .connectTimeout(serviceTimeout, TimeUnit.MILLISECONDS)
                            .writeTimeout(serviceTimeout, TimeUnit.MILLISECONDS)
                            .readTimeout(serviceTimeout, TimeUnit.MILLISECONDS)
                            .build() : getUnsafeOkHttpClient(serviceTimeout))
                    .build();
        }
        return retrofitselected;
    }

不要错过 OkHttpClient 的这个。

private static OkHttpClient getUnsafeOkHttpClient(int serviceTimeout) {
        try {
            // Create a trust manager that does not validate certificate chains
            final TrustManager[] trustAllCerts = new TrustManager[] {
                    new X509TrustManager() {
                        @Override
                        public void checkClientTrusted(java.security.cert.X509Certificate[] chain, String authType) throws CertificateException {
                        }

                        @Override
                        public void checkServerTrusted(java.security.cert.X509Certificate[] chain, String authType) throws CertificateException {
                        }

                        @Override
                        public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                            return new java.security.cert.X509Certificate[]{};
                        }
                    }
            };

            // Install the all-trusting trust manager
            final SSLContext sslContext = SSLContext.getInstance("SSL");
            sslContext.init(null, trustAllCerts, new java.security.SecureRandom());
            // Create an ssl socket factory with our all-trusting manager
            final SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();

            OkHttpClient.Builder builder = new OkHttpClient.Builder();
            builder.sslSocketFactory(sslSocketFactory);
            builder.hostnameVerifier(new HostnameVerifier() {
                @Override
                public boolean verify(String hostname, SSLSession session) {
                    return true;
                }
            });

            OkHttpClient okHttpClient = builder
                    .addInterceptor(new ResponseInterceptor())
                    .connectTimeout(serviceTimeout, TimeUnit.MILLISECONDS)
                    .writeTimeout(serviceTimeout, TimeUnit.MILLISECONDS)
                    .readTimeout(serviceTimeout, TimeUnit.MILLISECONDS)
                    .build();
            return okHttpClient;
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }

希望这对任何人都有帮助。

对于Retrofit1.9 和OkHttp3 用户,这里是解决方案,

.setClient(new Ok3Client(new OkHttpClient.Builder().readTimeout(60, TimeUnit.SECONDS).build()))

在 Kotlin 中:

首先你应该创建一个 OkHttp client 并添加 Retrofit builder

fun create(): Retrofit { 

        val client = OkHttpClient.Builder()
            .readTimeout(60,TimeUnit.SECONDS)
            .build()


        return Retrofit.Builder()
            .baseUrl(BASE_URL)
            .client(client)
            .addConverterFactory(GsonConverterFactory.create())
            .build()
    }
}
