我正在向 Rest Api 发送 Put 请求，以根据用户名更新用户信息，但出现以下错误
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<title>400 Bad Request</title>
<h1>Bad Request</h1>
<p>The browser (or proxy) sent a request that this server could not understand.</p>
API简介如下
/api/users/username GET, PUT Token
我创建我的请求如下，
headers = {'Content-Type': 'application/json',
'Token': token}
datap = [{'firstname': 'aaa1',
'lastname': 'aaa1',
'phone': '222222'}]
r = requests.put('http://127.0.0.1:8080/api/users/user1a', data=datap, headers=headers)
print(r.text)
如果需要更多信息，我可以提供，这里是其余 api 的代码片段
@bp.route('/users/<username>', methods=(['GET', 'PUT']))
@token_required
def username(username):
if request.method == 'GET':
return get_specific_user(username)
if request.method == 'PUT':
return put_specific_user(username, request)
def put_specific_user(username, request):
allowed_fields = ('firstname', 'lastname', 'phone')
if not request.is_json:
return jsonify({'status': 'FAILURE',
'message': 'Bad Request'}), 400
将 json 封装到 [] 后，现在我收到以下错误，因此它不再是错误的请求
File "C:\Python27\lib\site-packages\requests\api.py", line 131, in put
return request('put', url, data=data, **kwargs)
File "C:\Python27\lib\site-packages\requests\api.py", line 60, in request
return session.request(method=method, url=url, **kwargs)
File "C:\Python27\lib\site-packages\requests\sessions.py", line 519, in request
prep = self.prepare_request(req)
File "C:\Python27\lib\site-packages\requests\sessions.py", line 462, in prepare_request
hooks=merge_hooks(request.hooks, self.hooks),
File "C:\Python27\lib\site-packages\requests\models.py", line 316, in prepare
self.prepare_body(data, files, json)
File "C:\Python27\lib\site-packages\requests\models.py", line 507, in prepare_body
body = self._encode_params(data)
File "C:\Python27\lib\site-packages\requests\models.py", line 97, in _encode_params
for k, vs in to_key_val_list(data):
ValueError: too many values to unpack
最佳答案
更改如下
requests.put('http://127.0.0.1:8080/api/users/user1a', data=datap, headers=headers)
至
requests.put('http://127.0.0.1:8080/api/users/user1a', data=json.dumps(datap), headers=headers)
PS:我不知道为什么有人会给我-1 这个问题可以请一些mod 看看它。这样我就不会再这样做了。
