Http post请求Python失败。（必填字段）

我一直在尝试在该网站的API上执行HTTP post请求：

但它总是给我一个错误，说一个字段是必需的，即使我提到了键：

import requests

url = 'http://text-processing.com/api/sentiment/'
myobj = {'text  ': 'I am feeling reat'}

x = requests.post(url, data = myobj)

print(x.text)

答复：

<Response [200]>
Form Validation Errors
text: This field is required.

答复：

{"probability": {"neg": 0.30135019761690551, "neutral": 0.27119050546800266, "pos": 0.69864980238309449}, "label": "pos"}

删除“文本”后的空格，这样做有效

import requests

url = 'http://text-processing.com/api/sentiment/'
myobj = {'text': 'I am feeling reat'}

x = requests.post(url, data = myobj)

print(x.text)

用这样一个拼写错误发布一个问题真是太可惜了！谢谢

import requests

url = 'http://text-processing.com/api/sentiment/'
myobj = {'text': 'I am feeling reat'}

x = requests.post(url, data = myobj)

print(x.text)
