如何让while循环和json响应工作?

第一次使用输入userid运行脚本时,如果用户在线,它将正常运行,直到打印(f'{username}, {userid}' + '仍然在线…')卡住。 当用户离线时,当userid == str(ps['user_id']):不再为真时,程序不会继续执行else操作。 它类似于str(ps['user_id']):在调用脚本时从不更新。

userid = input('Input userID: ')
response = requests.post('website.com/api', headers=headers, data=data)
json_data = json.dumps(response.json(), indent=2)
data = json.loads(json_data)

while True: # Main loop to run if a user is online
    for ps in data['result']['page']['list']:
        if userid == str(ps['user_id']): # If a user is online print details
            username = ps['nick_name']
            print('Username: ' + ps['nick_name'])
            print('UserID: ' + str(ps['user_id']))           
            while userid == str(ps['user_id']): # Look if the user is still online (is in the json response)
                print(f'{username}, {userid}' + ' is still online...')
                time.sleep(3)
        else: # If user go offline(is not in the json response), break and restart main loop(first while loop).
            break

        print('Waiting for ' + f'{userid}' + ' to get online...') # Message until user go online again (is found in the json response).
        time.sleep(5)

  • 您不会在循环的任何地方更新数据,因此每次迭代都使用相同的陈旧数据。您可以在time.sleep(5)之前将生成数据的三行代码添加到循环中。这将给你更新的数据,并应解决你的问题。

    userid = input('Input userID: ')
    response = requests.post('website.com/api', headers=headers, data=data)
    json_data = json.dumps(response.json(), indent=2)
    data = json.loads(json_data)
    userList = data['result']['page']['list']
    isOnline = 0
    
    while True: # Main loop to run if a user is online
        hasLoggedIn = 0
        for user in userList:
    
            if str(user['user_id']) == userid and isOnline == 0: # If a user is online print details
                username = user['nick_name']
                print('Username: ' + user['nick_name'])
                print('UserID: ' + str(user['user_id']))
                print(f'{username}, {userid}' + ' is now online...')
                isOnline = 1
                hasLoggedIn = 1
                time.sleep(3)
    
            elif str(user['user_id']) == userid and isOnline == 1:       
                print(f'{username}, {userid}' + ' is still online...')
                hasLoggedIn = 1
                time.sleep(3)
    
        if hasLoggedIn == 0:    
            print('Waiting for ' + f'{userid}' + ' to get online...') # Message until user go online again (is found in the json response).
            isOnline = 0
            time.sleep(5)
    
        response = requests.post('website.com/api', headers=headers, data=data)
        json_data = json.dumps(response.json(), indent=2)
        data = json.loads(json_data)
        userList = data['result']['page']['list']
