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。
