騰訊雲對象存儲

公司需要把軟體日志檔案傳到服務端

對于 Qt 開發者來說當然不會用它們的 SDK 了，用是不可能用的，又不是不會coding

2021-01-27 看的文檔開始開發

上傳檔案

對，沒錯，上傳檔案用的叫 put object

上傳檔案到存儲桶，對沒錯，這個名字很 OK

put object:https://cloud.tencent.com/document/product/436/7749

為了搞這個上傳檔案 api, 搞了一天半才測試成功，一直吐槽文檔寫的跟奧利給一樣，氣的不行，第一天下班我還送出了工單，騰訊雲小姐姐還電話給我問我要錯誤傳回的參數，後來我自己調通了。

putUrl(“1.txt”)

注意把裡面的 xxxx 都換成你自己申請的參數
