无法打印json值

Question

我用python编写了这段代码，其目的是通过websocket发送一个文本文件.c.txt（不管怎样，我一直在发送一个helloworld.c）

问题是当我测试它时，代码没有超出print("I'm here!")

 def onMessage_function(self, client_id, message): 
        print("Here's the message I received " + message + "\n\n\n")
        dumpedMSG = json.dumps(message)
        loadedMSG = json.loads(dumpedMSG)
        if 'file_name' in loadedMSG:
            print("I'm here!")
            print(loadedMSG['file_name'])
        else:
        # do something else here.

谢谢大家!

很难说，但这有用吗

def onMessage_function(self, client_id, message): 
    print("Here's the message I received " + message + "\n\n\n")
    loadedMSG = json.loads(message)
    if 'file_name' in loadedMSG:
        print("I'm here!")
        print(loadedMSG['file_name'])
    else:
    # do something else here.

在原始版本中loadedMSG将与message相同，因此'file_name' in loadedMSG将是子字符串检查，而不是字典键检查。“我在这儿！”后面的字然后将抛出一个异常，如果您只接收通过套接字发送的内容，则可能看不到该异常
