从文件加载数据时格式错误 json

Question

我尝试使用 microsoft graph API 创建 azure ad b2c 用户流：

user_flow.json

{
    "id": "Customer",
    "userFlowType": "signUpOrSignIn",
    "userFlowTypeVersion": 3
}

main.py

    def create_user_flow(jsonConfigFile, msgraph_token):
        url = "https://graph.microsoft.com/beta/identity/b2cUserFlows/"
        headers = {
        'Content-Type': 'application/json',
        'Authorization': 'Bearer ' + msgraph_token
        }     
        with open(jsonConfigFile) as data :
            payload = (json.load(data))
            data.close()
        
        r = requests.request("POST", url, headers=headers, data=payload)
        return r.json()

print(create_user_flow("user_flow.json",get_graph_token())

{ "error": { "code": "BadRequest", "message": "Unable to read JSON request payload. Please ensure Content-Type header is set and payload is of valid JSON format.", "innerError": { "date": "2022-04-13T13:09:00", "request-id": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx", "client-request-id": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" } } }

但是如果我按如下方式硬编码 json，它就可以工作了：

    def create_user_flow(jsonConfigFile, msgraph_token):
        url = "https://graph.microsoft.com/beta/identity/b2cUserFlows/"
        headers = {
        'Content-Type': 'application/json',
        'Authorization': 'Bearer ' + msgraph_token
        }     
        payload = json.dumps({
            "id": "Customer",
            "userFlowType": "signUpOrSignIn",
            "userFlowTypeVersion": 3
        })
        
        r = requests.request("POST", url, headers=headers, data=payload)
        return r.json()

print(create_user_flow("user_flow.json",get_graph_token())

有人可以解释一下我在从文件加载 json 时做错了什么吗？

json.load 使用 JSON 字符串的 key-value 对创建一个新字典，它 returns 这个新字典。

您可以将数据作为字符串读取并在请求中发送

def create_user_flow(jsonConfigFile, msgraph_token):
        url = "https://graph.microsoft.com/beta/identity/b2cUserFlows/"
        headers = {
        'Content-Type': 'application/json',
        'Authorization': 'Bearer ' + msgraph_token
        }     
        with open(jsonConfigFile) as data :
            payload = data.read()
            data.close()
        
        r = requests.request("POST", url, headers=headers, data=payload)
        return r.json()

print(create_user_flow("user_flow.json",get_graph_token())

或调用 json.dumps 加载 JSON 字典。

def create_user_flow(jsonConfigFile, msgraph_token):
        url = "https://graph.microsoft.com/beta/identity/b2cUserFlows/"
        headers = {
        'Content-Type': 'application/json',
        'Authorization': 'Bearer ' + msgraph_token
        }     
        with open(jsonConfigFile) as data :
        payload = (json.load(data))
        data.close()
        
        r = requests.request("POST", url, headers=headers, data=json.dumps(payload))
        return r.json()

print(create_user_flow("user_flow.json",get_graph_token())
