requests模塊報錯：Use body.encode('utf-8') if you want to send it encoded in UTF-8.

在做 企業向微信用戶個人付款  功能時，調用第三方sdk，在 進行 requests 的post請求時，

代碼如下

req = requests.post(url, data=data,cert(api_client_cert_path, api_client_key_path),)

報錯如下：

Process finished with exit code 1

主要原因是 請求body里面有 漢字，沒有進行untf-8編碼導致，解決方法，對data進行 encode()編碼 即可

req = requests.post(url, data=data.encode(),cert=(api_client_cert_path, api_client_key_path),)
