在Java中進行api調用時，出現“Exception in thread "main" java.net.SocketTimeoutException: timeout”，“Caused by: java.net.SocketTimeoutException: Read timed out”的錯誤

在本地使用 OkHttpClient 創建請求客戶端，調試api接口時，出現了表示中所述的錯誤，先貼出完整錯誤代碼

問題在於api里面處理的時間比較久，而我所創建的 OkHttpClient 客戶端並沒有給足夠的時間取處理，因此需要設置更長的連接和讀取時間，延長至50秒，可順利通過。代碼如下所示：

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

網上有說通過下面代碼設置超時時間，但是沒有找到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
