OkHttp并没有内置的请求重试机制,但我们可以通过自定义Interceptor来实现请求的重试机制。
以下是一个简单的示例代码:
public class RetryInterceptor implements Interceptor { private int maxRetry; private int retryCount = 0; public RetryInterceptor(int maxRetry) { this.maxRetry = maxRetry; } @Override public Response intercept(Chain chain) throws IOException { Request request = chain.request(); Response response = chain.proceed(request); while (!response.isSuccessful() && retryCount < maxRetry) { retryCount++; response = chain.proceed(request); } return response; } }
在使用OkHttp时,我们可以创建一个OkHttpClient并添加上述的RetryInterceptor:
OkHttpClient client = new OkHttpClient.Builder() .addInterceptor(new RetryInterceptor(3)) .build();
这样设置后,每次请求失败时,RetryInterceptor会尝试重新发起请求,最多重试3次。这样就实现了简单的请求重试机制。
