我正在尝试从ONVIF IP摄像机获取运动检测器事件。我可以获取订阅的主题地址，但是当我尝试从中提取消息时，会收到错误消息：
Error 401 fault detected[no subcode]

<html><head><title>Document Error: Unauthorized</title></head>
<body><h2>Access Error: 401 -- Unauthorized</h2>

我创建了多个代理，例如DeviceProxy，EventsProxy，PullPointProxy，并为每个请求添加了安全标头和时间戳，但只有PullPointProxy无法授权它们。

请帮助您理解为什么只有PullMessages返回错误以及正确验证需要哪些特定参数？
答案 0 :(得分：0)
可以向谁考虑...
问题出在WS-Addressing标头中： https://www.w3.org/Submission/ws-addressing/ https://www.genivia.com/doc/wsdd/html/wsa_0.html
我将其添加到我的PullMessage请求中，并得到了摄像头的响应。
代码应为：
