Python JSON内容中的虚幻换行符

背景

我使用Python请求将数据发布到google电子表格。由于意外的令牌“\n”，请求失败。但是，据我所知，我发送的JSON内容中没有换行符。这些换行符来自哪里？也许我需要在标题中定义内容长度。这里的任何方向都会有帮助

Python代码

def appendData(self, sheetName, rowData):

        rangeName = sheetName+"!A1"
        url = self.baseUrl+"/"+self.spreadsheetId+"/values/"+rangeName+":append?valueInputOption=RAW"

        requestBody = {
            'values': rowData
        }

        print("\n\nREQUEST BODY\n\n "+str(requestBody))

        try:
            response, content = self.service.request(url,
                                        method="POST",
                                        headers=self.headers,
                                        body=str(requestBody))
        except:
            print("Failed appending data")

        print("\n\nRESPONSE\n"+str(response))
        print("\n\nCONTENT\n"+str(content))

输出

REQUEST BODY

标题

远程API不是抱怨换行符，而是抱怨unicode前缀：

>>> print("Invalid JSON payload received. Unexpected token.\n'], ['Lower Limit', u'4.9', u'4.9', u'4.\n                    ^")
Invalid JSON payload received. Unexpected token.
'], ['Lower Limit', u'4.9', u'4.9', u'4.
                    ^

要将类似JSON的字典转换为JSON字符串，请使用

JSON.dumps

：

from json import dumps
body = dumps(requestBody)
