的Python的request.POST不接受解释

这是字典答案的印版：

{'Emails': set([u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected] ', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected] ', u' [email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u"elberta.o'[email protected]", u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u' [email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', None, u'[email protected] ', u'[email protected]']), '# of Emails per Domain': {u'@hotmail.com': 22, u'@yahoo.com': 18, u'@gmail.com': 18}, 'April Users': 70}

当我运行：

r = requests.post('https://9g9xhayrh5.execute-api.us-west-2.amazonaws.com/test/data', data = answers)

我收到此错误：

{"message": "Could not parse request body into json: Unrecognized token \'Emails\': was expecting (\'true\', \'false\' or \'null\')\n at [Source: [[email protected]; line: 1, column: 8]"}

不知道这是什么意思，我试图解析数据到JSON，为什么它不喜欢'电子邮件'字符串？

如果我添加那样json.dump代码我得到：

TypeError 

TypeError: set([u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected] ', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected] ', u' [email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u"elberta.o'[email protected]", u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u' [email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', u'[email protected]', None, u'[email protected] ', u'[email protected]']) is not JSON serializable

JSON不知道'set'。此外，你绝对不应该在这里发布这些电子邮件地址。 – L3viathan

我假设这些都是假的，但好的电话 –

试试'answers ['Emails'] = list（answers ['Emails']）'。 – L3viathan

TypeError: set([ ... ]) is not JSON serializable

集不是JSON序列化。您可以将所有的集合转换成列出了词典：

answers = {key: list(value) if isinstance(value, set) else value 
      for key, value in answers.items()}

^{（请注意，这不会对嵌套的字典上班的）。}

或者，使用将处理设置序列化的custom JSON encoder。

转储和装载它带回json通常有助于调试：

import json 

answers = json.loads(json.dumps(answers)) 
r = requests.post('https://9g9xhayrh5.execute-api.us-west-2.amazonaws.com/test/data', data=answers)

不错的建议，我试过这种方法，但我得到一个TypeError –

@AdamWeitzman请发布回溯，这可能会给我们一个线索是怎么回事。谢谢！ – alecxe

张贴在上面，我认为这是与该设置有关... ....但不知道 –

这工作：

import requests 
import json 
answers = {} #... 
url = "..." 
answers['Emails'] = list(answers['Emails']) 
r = requests.post(url, data=json.dumps(answers))

其他方式不工作的原因是，默认情况下请求使用内容类型application/x-www-form-urlencoded而不是JSON发送数据。使用请求库

r = requests.post(url, json=answers)

调试代码，你可以look at a prepared request发送之前：

要改变这种状况，你也可以使用json，而不是data参数。
