Python Server和Java Client:奇怪的行為接收數據

[英]Python Server and Java Client: Weird behaviour receiving data

我正在使用python創建服務器,並使用Java(Android)創建客戶端。 我面臨的問題是將數據正確地從一個獲取到另一個。

我讓Java客戶端嘗試這樣的登錄:

SettingsManager settingsman = SettingsManager.getInstance(params[0]);
                int port = Integer.parseInt(settingsman.getPort());
                String ip = settingsman.getIp();
                server = new Socket(ip, port);
                input = new DataInputStream(server.getInputStream());
                output = new DataOutputStream(server.getOutputStream());
                output.writeChars(LOGIN_REQ);
                output.writeChars(settingsman.getUserName());
                output.writeChars(settingsman.getPassword());
                String token = Integer.toString(input.read());
                //Check if the login has failed
                if(token == "0"){
                    token = null;
                }
                return token;

Python服務器接收到的是這樣的:

    opcode = c.recv(2)
    opcode  = opcode.decode('utf-8')
    print("OPCODE:" + opcode + str(type(opcode)))
    if(opcode == "0"):
        "Login action"
        print("STARTING TO RECV!")
        login = c.recv(1024).decode('utf-8')
        print("RECEIVED LOGIN: " + login)
        password = c.recv(1024).decode('utf-8')
        print("PASSWORD: " + password)
        print("USERNAME: " + username)
        setman = SettingsManager()
        setuser = setman.seccam_user()
        setpass = setman.seccam_password()

        if login == setuser & password == setpass:
            print("Login is good!")
            """Generate random token and save it to the settings file"""
    elif(opcode == "1"):
        pass
    else:
        print("OTHER!")

這是輸出:

OPCODE:0<class 'str'>
OTHER!

即使操作碼似乎是一個字符串並且是正確的值,該程序仍無法正確輸入If語句

誰能告訴我我在做什么錯?

謝謝

好吧,我解決了我的問題。 在我的Java代碼中使用WriteBytes效果更好!
