我用資料將資料從客戶端發送到服務器。

我嘗試使用客戶端中的執行緒將連續資料從客戶端發送到服務器，但出現 Abort 錯誤。

我在 on_connect 方法上嘗試了執行緒，并且每次都會像下面的代碼一樣添加資料。

我當時在 sendData 函式上嘗試了執行緒，也出現了 Abort 錯誤。

**如果我想從客戶端向服務器發送連續資料，有什么方法。

**發送資料后關閉客戶端并再次連接服務器，可以嗎？

**不關閉服務器從客戶端到服務器的連續發布請求資料？

uj5u.com熱心網友回復：

因此，您的代碼不完整，包含大量不需要的依賴項，并且沒有顯示您要執行的操作。

這是自包含的代碼，請從這里開始并保持自包含以說明您遇到的問題。
