requests模块报错：Use body.encode('utf-8') if you want to send it encoded in UTF-8.

在做 企业向微信用户个人付款  功能时，调用第三方sdk，在 进行 requests 的post请求时，

代码如下

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

报错如下

Process finished with exit code 1

主要原因是 请求body里面有 汉字，没有进行untf-8编码导致，解决方法，对data进行 encode()编码 即可

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