OkHttp并沒有內(nèi)置的請(qǐng)求重試機(jī)制,但我們可以通過自定義Interceptor來實(shí)現(xiàn)請(qǐng)求的重試機(jī)制。
以下是一個(gè)簡(jiǎn)單的示例代碼:
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時(shí),我們可以創(chuàng)建一個(gè)OkHttpClient并添加上述的RetryInterceptor:
OkHttpClient client = new OkHttpClient.Builder()
.addInterceptor(new RetryInterceptor(3))
.build();
這樣設(shè)置后,每次請(qǐng)求失敗時(shí),RetryInterceptor會(huì)嘗試重新發(fā)起請(qǐng)求,最多重試3次。這樣就實(shí)現(xiàn)了簡(jiǎn)單的請(qǐng)求重試機(jī)制。
