以下代码段引发了错误

    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

参数为Make_Payment_params = {“ debitAccountNumber”：12003189487，“ creditAccountNumber”：12065812627，“ amount”：100，“ requestedExecutionDate”：“ 2019-03-09”}

并引发错误TypeError（“ quote_from_bytes（）预期字节”）TypeError：quote_from_bytes（）预期字节

非常感谢帮助
