我跑的时候：
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: [B@311a7237; line: 1, column: 8]"}
不确定这意味着什么，我已经尝试将数据解析为json，为什么它不像“电子邮件”那样？字符串？
如果我添加json.dump代码，我会得到：

答案 0 :(得分：1)
TypeError: set([ ... ]) is not JSON serializable
集不是JSON可序列化的。您可以将所有集合转换为字典中的列表：
answers = {key: list(value) if isinstance(value, set) else value
for key, value in answers.items()}
（请注意，这不适用于嵌套字典）。
或者，使用可处理设置序列化的custom JSON encoder。
使用json转储并加载它通常有助于调试：
import json
answers = json.loads(json.dumps(answers))
r = requests.post('https://9g9xhayrh5.execute-api.us-west-2.amazonaws.com/test/data', data=answers)
答案 1 :(得分：1)
这有效：
import requests
import json
answers = {} #...
url = "..."
answers['Emails'] = list(answers['Emails'])
r = requests.post(url, data=json.dumps(answers))
另一种方式不起作用的原因是默认情况下请求使用Content-Type application/x-www-form-urlencoded而不是JSON发送数据。
要更改此设置，您还可以使用json代替data参数：
r = requests.post(url, json=answers)
要使用请求库调试代码，您可以在发送之前look at a prepared request。
