python - 故障排除引发 TypeError ("quote_from_bytes() expected bytes")

Question

以下代码引发了我的错误

    def __to_canonical_querystring_post(self, params):
    canonical_querystring = ""
    # parameters have to be sorted alphabetically for the signing part
    for param_key, param_value in sorted(params.items()):
        if canonical_querystring != "":
            canonical_querystring += "&"
        canonical_querystring += param_key + "=" + urllib.parse.quote(param_value)
    return canonical_querystring

参数是
Make_Payment_params = {
"debitAccountNumber": 12003189487,
"creditAccountNumber": 12065812627,
“金额”:100，
"requestedExecutionDate": "2019-03-09"
}

并且错误是 raise TypeError("quote_from_bytes() expected bytes")
类型错误:quote_from_bytes() 预期字节数

非常感谢帮助

urllib.parse.quote 的参数必须是字符串，但您的代码有时会传递整数。将调用更改为类似 urllib.parse.quote(str(param_value)) 的内容应该解决问题。
