如何在Retrofit库中设置超时？-Java 学习之路

137

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？

我这样设置Retrofit：

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 . 如果您未指定客户端，则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OkHttp客户端，也来自Square .

1. Add the library dependency

在build.gradle中，包含以下行：
```
compile 'com.squareup.okhttp:okhttp:x.x.x'
```
x.x.x 是所需的库版本 .

2. Set the client

例如，如果要将超时设置为60秒，请对版本2之前的Retrofit和版本3之前的Okhttp（ FOR THE NEWER VERSIONS, SEE THE EDITS ）执行此操作：
```
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();
}
```
EDIT 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();
```

EDIT 2

自 2.x.x 以来的改造版本也使用构建器模式，因此将上面的返回块更改为：
```
return new Retrofit.Builder()
    .baseUrl(BuildConfig.BASE_URL)
    .addConverterFactory(GsonConverterFactory.create())
    .client(okHttpClient)
    .build();
```
如果使用类似我的 providesRestAdapter 方法的代码，则将方法返回类型更改为Retrofit .

ps：如果你的minSdkVersion大于8，你可以使用 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 .

这些答案对我来说已经过时了，所以这就是它如何解决的问题 .

添加OkHttp，在我的情况下版本是 3.3.1 ：

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

然后在构建您的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();

我正在使用 Retrofit 1.9 获取 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文件中 .

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())

这将是设置每个服务超时的最佳方法（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 .

private static OkHttpClient getUnsafeOkHttpClient(int serviceTimeout) {
        try {
            // Create a trust manager that does not validate certificate chains
            final TrustManager[] trustAllCerts = new TrustManager[] {

                        @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) {
