Bad json format when loading data from file-CodePudding

I try to create an azure ad b2c user flow using microsoft graph API :

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" } } }

But if I hardcode the json as follow, it works :

    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())

Could someone explain me what I am doing wrong while loading my json from a file ?

CodePudding user response：

json.load creates a new dictionary with the key-value pairs of the JSON string and it returns this new dictionary.

You can read the data as a string and send it in the request

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())

or call json.dumps for load JSON dictionary.

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())
