Okhttp 自定义重试次数

Okhttp通过自定义,可以通过拦截器的方式

使用Rxjava 实现

/**
 * @params maxRetry 最大次数
 */
  private class InterceptorRetryOkhttp(private val maxRetry: Long) : Interceptor, KoinComponent {
        override fun intercept(chain: Interceptor.Chain): Response {

            return try {
                Single.create{ it.onSuccess(chain.proceed(chain.request())) }.retry(maxRetry-1).blockingGet()
            } catch (e: Exception) {
                chain.proceed(chain.request())
            }
        }

    }

使用递归实现

private class InterceptorRetryOkhttp(private val maxRetry: Long) : Interceptor, KoinComponent {
    override fun intercept(chain: Interceptor.Chain): Response {

        return retry(chain=chain,retryCount = 0)
    }
    private fun retry(chain: Interceptor.Chain,retryCount:Long):Response{
        val request =chain.request()
        var response:Response? =null

        try {
            response =chain.proceed(request)
        }catch (e:Exception){
            if (retryCount<maxRetry){
                retry(chain, retryCount+1)
            }
        }
        return  response?: chain.proceed(request)
    }

}

```kotlin
OkHttpClient.Builder().addInterceptor(InterceptorRetryOkhttp(maxRetry=3))
