我在我的应用程序中使用 Retrofit 库，并且我想设置一个60秒的超时时间。Retrofit有没有一些方法可以实现这个？
我是这样设置Retrofit的：
这是我设置Retrofit的方式：
RestAdapter restAdapter = new RestAdapter.Builder()
.setServer(BuildConfig.BASE_URL)
.setConverter(new GsonConverter(gson))
.build();
我如何设置超时时间？
您可以在底层的HTTP客户端上设置超时时间。如果您没有指定客户端，Retrofit将创建一个默认连接和读取超时时间的客户端。要设置自己的超时时间，您需要配置自己的客户端并将其提供给RestAdapter.Builder。
一个可选方案是使用Square提供的OkHttp客户端。
1. 添加库依赖项
在build.gradle中，包含以下行：
compile 'com.squareup.okhttp:okhttp:x.x.x'
其中x.x.x是所需库的版本。
2. 设置客户端
例如，如果您想设置60秒的超时时间，在Retrofit 2之前和Okhttp 3之前这样做（对于更新版本，请参见编辑部分）：
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();
}

从 3.x.x 版本开始，您需要以这种方式设置依赖关系：
compile 'com.squareup.okhttp3:okhttp:x.x.x'
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();
更多信息请参见超时

2.x.x以后的Retrofit版本也使用了构建器模式，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();
providesRestAdapter方法一样的代码，则将该方法的返回类型更改为Retrofit。有关更多信息，请参见Retrofit 2 ——从1.9升级指南
附：如果您的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，请参见TimeUnit。
这些答案对我来说已经过时了，所以这是它的解决方法。
添加OkHttp，我的情况下版本是3.3.1：
compile 'com.squareup.okhttp3:okhttp:3.3.1'
在构建Retrofit之前，请执行以下操作：
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 ApiClient {
private static Retrofit retrofit = null;
private static final Object LOCK = new Object();
public static void clear() {
synchronized (LOCK) {
retrofit = null;
}
}
public static Retrofit getClient() {
synchronized (LOCK) {
if (retrofit == null) {
Gson gson = new GsonBuilder()
.setLenient()
.create();
OkHttpClient okHttpClient = new OkHttpClient().newBuilder()
.connectTimeout(40, TimeUnit.SECONDS)
.readTimeout(60, TimeUnit.SECONDS)
.writeTimeout(60, TimeUnit.SECONDS)
.build();
retrofit = new Retrofit.Builder()
.client(okHttpClient)
.baseUrl(Constants.WEB_SERVICE)
.addConverterFactory(GsonConverterFactory.create(gson))
.build();
}
return retrofit;
}
}
public static RequestBody plain(String content) {
return getRequestBody("text/plain", content);
}
public static RequestBody getRequestBody(String type, String content) {
return RequestBody.create(MediaType.parse(type), content);
}
}
@FormUrlEncoded
@POST("architect/project_list_Design_files")
Call<DesignListModel> getProjectDesign(
@Field("project_id") String project_id);
@Multipart
@POST("architect/upload_design")
Call<BoqListModel> getUpLoadDesign(
@Part("user_id") RequestBody user_id,
@Part("request_id") RequestBody request_id,
@Part List<MultipartBody.Part> image_file,
@Part List<MultipartBody.Part> design_upload_doc);
private void getMyProjectList()
{
ApiInterface apiService = ApiClient.getClient().create(ApiInterface.class);
Call<MyProjectListModel> call = apiService.getMyProjectList("",Sorting,latitude,longitude,Search,Offset+"",Limit);
call.enqueue(new Callback<MyProjectListModel>() {
@Override
public void onResponse(Call<MyProjectListModel> call, Response<MyProjectListModel> response) {
try {
Log.e("response",response.body()+"");
} catch (Exception e)
{
Log.e("onResponse: ", e.toString());
}
}
@Override
public void onFailure(Call<MyProjectListModel> call, Throwable t)
{
Log.e( "onFailure: ",t.toString());
}
});
}
// file upload
private void getUpload(String path,String id)
{
ApiInterface apiService = ApiClient.getClient().create(ApiInterface.class);
MultipartBody.Part GalleryImage = null;
if (path!="")
{
File file = new File(path);
RequestBody reqFile = RequestBody.create(MediaType.parse("multipart/form-data"), file);
GalleryImage = MultipartBody.Part.createFormData("image", file.getName(), reqFile);
}
RequestBody UserId = RequestBody.create(MediaType.parse("text/plain"), id);
Call<uplod_file> call = apiService.geUplodFileCall(UserId,GalleryImage);
call.enqueue(new Callback<uplod_file>() {
@Override
public void onResponse(Call<uplod_file> call, Response<uplod_file> response) {
try {
Log.e("response",response.body()+"");
Toast.makeText(getApplicationContext(),response.body().getMessage(),Toast.LENGTH_SHORT).show();
} catch (Exception e)
{
Log.e("onResponse: ", e.toString());
}
}
@Override
public void onFailure(Call<uplod_file> call, Throwable t)
{
Log.e( "onFailure: ",t.toString());
}
});

Kotlin中的做法：
首先，您应该创建一个OkHttp客户端并将其添加到Retrofit构建器中。
fun create(): Retrofit {
val client = OkHttpClient.Builder()
.readTimeout(60,TimeUnit.SECONDS)
.build()
return Retrofit.Builder()
.baseUrl(BASE_URL)
.client(client)
.addConverterFactory(GsonConverterFactory.create())
.build()
}
}
retrofit2的超时时间：创建OkHttpClient对象（默认超时时间为10秒）。
val okHttpClient = OkHttpClient.Builder()
.connectTimeout(30, TimeUnit.SECONDS)
.writeTimeout(30, TimeUnit.SECONDS)
.readTimeout(30, TimeUnit.SECONDS)
.build()
然后将这个对象添加到你的Retrofit构建器中。
val retrofit = Retrofit.Builder()
.addConverterFactory(ScalarsConverterFactory.create())
.client(okHttpClient)
.baseUrl(BASE_URL)
.build()
从这个包中导入TimeUnit
import java.util.concurrent.TimeUnit
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);
}
}

在这里，我们在构建API rest服务实现之前设置自定义URL客户端连接客户端。
import com.google.gson.Gson
import com.google.gson.GsonBuilder
import retrofit.Endpoint
import retrofit.RestAdapter
import retrofit.client.Request
import retrofit.client.UrlConnectionClient
import retrofit.converter.GsonConverter
class ClientBuilder {
public static <T> T buildClient(final Class<T> client, final String serviceUrl) {
Endpoint mCustomRetrofitEndpoint = new CustomRetrofitEndpoint()
Gson gson = new GsonBuilder().excludeFieldsWithoutExposeAnnotation().create()
RestAdapter.Builder builder = new RestAdapter.Builder()
.setEndpoint(mCustomRetrofitEndpoint)
.setConverter(new GsonConverter(gson))
.setClient(new MyUrlConnectionClient())
RestAdapter restAdapter = builder.build()
return restAdapter.create(client)
}
}
public final class MyUrlConnectionClient extends UrlConnectionClient {
@Override
protected HttpURLConnection openConnection(Request request) {
HttpURLConnection connection = super.openConnection(request);
connection.setConnectTimeout(15 * 1000);
connection.setReadTimeout(30 * 1000);
return connection;
}
}
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);
}
}
public class ApiClient {
private static Retrofit retrofit = null;
private static final Object LOCK = new Object();
public static void clear() {
synchronized (LOCK) {
retrofit = null;
}
}
public static Retrofit getClient() {
synchronized (LOCK) {
if (retrofit == null) {
Gson gson = new GsonBuilder()
.setLenient()
.create();
OkHttpClient okHttpClient = new OkHttpClient().newBuilder()
.connectTimeout(40, TimeUnit.SECONDS)
.readTimeout(60, TimeUnit.SECONDS)
.writeTimeout(60, TimeUnit.SECONDS)
.build();
// Log.e("jjj", "=" + (MySharedPreference.getmInstance().isEnglish() ? Constant.WEB_SERVICE : Constant.WEB_SERVICE_ARABIC));
retrofit = new Retrofit.Builder()
.client(okHttpClient)
.baseUrl(Constants.WEB_SERVICE)
.addConverterFactory(GsonConverterFactory.create(gson))
.build();
}
return retrofit;
}`enter code here`
}
public static RequestBody plain(String content) {
return getRequestBody("text/plain", content);
}
public static RequestBody getRequestBody(String type, String content) {
return RequestBody.create(MediaType.parse(type), content);
}
}

gson对象是从哪里获取的？我按照教程走到了这一步，使用RestAdapter restAdapter = new RestAdapter.Builder().setEndpoint(url).build();创建了RestAdapter。但是我的类中没有任何Gson对象，尽管我已经在项目中包含了 gson 和 converter-gson 库。 - Solacepublic Gson providesGson() { return new GsonBuilder().create(); }. 所以我做了这个：Gson gson = module.providesGson(); RestAdapter adapter = module.providesRestAdapter(gson);。其中，module是一个合适的类的实例，该类拥有所有这些方法。 - androidevilcompile 'com.squareup.okhttp3:okhttp:3.x.x'，就像Teo在下面的答案中所示。 - NineToeNerd
