問題描述

使用Workerman\Mqtt\Client連接mqtt服務(wù)器就報錯 "Mqtt client: Connection Refused, bad user name or password"，去掉賬號密碼 然后去掉mqtt服務(wù)的賬號密碼認證就能正常連接。

程序代碼或配置

# mqtt.php配置（這個是通過process.php方式的配置）
return [
    // 'broker' => 'mqtt://106.53.125.85:1883',  # MQTT 服務(wù)器地址
    'broker' => 'mqtt://iot.yuanqq.net:1883',  # MQTT 服務(wù)器地址
    'client_id' => 'eatsplus_mqtt_' . bin2hex(random_bytes(4)),
    'username' => "Firstsensor",      // 新增用戶名
    'password' => "*******",       // 新增密碼
    'keepalive' => 60,
    'protocol' => 4,
    'clean_session' => true,
    'topics' =>  [
        ['topic' => 'test_topic', 'qos' => 1],
        ['topic' => 'fst_data_report/#', 'qos' => 1],
        ['topic' => 'fst_para_report/#', 'qos' => 1],
    ]
];

# composer.json配置

重現(xiàn)問題的步驟

1、首選確認一點 username,password是沒有問題的，因為使用mqtt工具可以正常連接并接收數(shù)據(jù)（看圖）。

2、去掉mqtt服務(wù)的賬號密碼認證，然后刪除配置文件中的username,password就可以正常連接接收數(shù)據(jù)。
3、調(diào)整過workerman/mqtt的版本，之前是2.1降級到2.0
4、也通過控制器中簡易調(diào)用還是同樣報錯（特意新加的用戶名和密碼），如圖

結(jié)果如圖：

還有一點就是 通過mqtt客戶端連接的時候,mqtt服務(wù)器能正常收到連接請求，且能看到傳遞的用戶名，如圖：


但我使用webman連接時的日志中好像根本看不到用戶名

操作系統(tǒng)環(huán)境及workerman/webman等具體版本

本地環(huán)境：win10,
mqtt客戶端：MQTTX Version: v1.11.1
mqtt服務(wù)端：Node 'emqx@172.23.0.8' 5.8.5 is started
