如何禁用与OkHttp的一个连接的重试? [英] How to disable retries for one connection with OkHttp?

问题描述

我正在使用OkHttp，并且想在特定的api调用上禁用连接重试.这是正确的方法吗?:

I'm using OkHttp and want to disable connection retries on a particular api call. Is this the correct way to do it?:

mMyGlobalClient = new OkHttpClient();

....

public void makeConnection(...) {

    OkHttpClient client = null;
    if (disableRetries) {
        OkHttpClient clone = mMyGlobalClient.clone();
        clone.setRetryOnConnectionFailure(false);
        client = clone;
    } else {
        client = mMyGlobalClient;
    }

    client.newCall(...);
}

这个想法来自这篇文章:

The idea comes from this post:

https://github.com/square/okhttp/pull/1259#问题53157152

大多数应用程序都不想全局禁用重试.相反，使用 clone()为特定的非幂等请求获取OkHttpClient， 然后使用该设置配置该客户端.

Most applications won't want to disable retry globally. Instead, use clone() to get an OkHttpClient for a specific, non-idempotent request, then configure that client with the setting.

我要对此一次呼叫禁用重试的原因是，如果它被我的服务器处理两次，则可能具有破坏性:

The reason I want to disable retries for this one call is because it can be destructive if it gets handled twice by my server:

谢谢

推荐答案

是的，这是正确的方法.

Yes, this is the right way.

顺便说一句，如果您不介意的话，可以写得简单些

By the way, if you don't mind, you could write it a little simpler

mMyGlobalClient = new OkHttpClient();

....

public void makeConnection(...) {

    OkHttpClient client = null;
    if (disableRetries) {
        client = mMyGlobalClient.clone();
        client.setRetryOnConnectionFailure(false);
    } else {
        client = mMyGlobalClient;
    }

    client.newCall(...);
}
