在Java中进行api调用时，出现“Exception in thread "main" java.net.SocketTimeoutException: timeout”，“Caused by: java.net.SocketTimeoutException: Read timed out”的错误

在本地使用 OkHttpClient 创建请求客户端，调试api接口时，出现了表示中所述的错误，先贴出完整错误代码

问题在于api里面处理的时间比较久，而我所创建的 OkHttpClient 客户端并没有给足够的时间取处理，因此需要设置更长的连接和读取时间，延长至50秒，可顺利通过。代码如下所示：

OkHttpClient client = new OkHttpClient().newBuilder().connectTimeout(50000, TimeUnit.MILLISECONDS)
                .readTimeout(50000, TimeUnit.MILLISECONDS)
                .build();

网上有说通过下面代码设置超时时间，但是没有找到set的方法，有知情的小伙伴告知一下吧。

OkHttpClient client = new OkHttpClient();
client.setConnectTimeout(30, TimeUnit.SECONDS); // connect timeout
client.setReadTimeout(30, TimeUnit.SECONDS);    // socket timeout
