JSON 负载的 Python 字符串连接

Question

我正在尝试修改 Postman 生成的这段代码，以用字符串变量替换硬编码字符串，但我不断收到

KeyError: '\n\t"username"'

这是代码

username = "jose"

email = "some_email"

password = "1234"

url = "some_url"

payload = '{\n\t\"username\": {},\n\t\"email\": {},\n\t\"password\": {}\n}'.format(username, email, password)

headers = {

  'Content-Type': 'application/json'

}

response = requests.request("POST", url, headers=headers, data=payload)

print(response.text.encode('utf8'))

Answer 1

你可以这样正确地形成你的json：import jsonusername = "jose"email = "some_email"password = "1234"url = "some_url"payload = json.dumps({"username": username, "email":email, "password":password}, indent=4)headers = { 'Content-Type': 'application/json'}response = requests.request("POST", url, headers=headers, data=payload)print(response.text.encode('utf8'))

Answer 2

看看这里的例子：https ://requests.readthedocs.io/en/master/user/quickstart/>>> r = requests.post('https://httpbin.org/post', data = {'key':'value'})您可以只使用字典来获取数据。
