请求失败，HTTP 状态为 404：未找到

Question

我正在尝试从 .Net 客户端调用 php soap web 服务，但出现以下错误：

System.Net.WebException was unhandled by user code
  Message="**The request failed with HTTP status 404: Not Found**."
  Source="System.Web.Services"
  StackTrace:

       at System.Web.UI.Control.LoadRecursive()
       at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)
  InnerException: 

我无法得到问题是 php Soap 服务器端或 .Net 客户端。我是 php 新手。

请帮助任何人。

以下是 SOAP 服务器代码：

ini_set("soap.wsdl_cache_enabled", "0");
$server = new SoapServer("http://10.20.1.161/api/soap/report.wsdl");
$server->addFunction("testServer");
$server->handle();

以下是 SOAP .Net 客户端代码：

 protected void Page_Load(object sender, EventArgs e)
        {
            try
            {
                MyService ms = new MyService(); 
                Object ac = ms.testServer();
            }
            catch (Exception ae)
            {
                Response.Write(ae);
            }
        }

我想分享我的 WSDL，就是这样......

请帮忙..

Answer 1

您收到 404 响应，404 或 Not Found 错误消息是 HTTP 标准响应代码，表示客户端能够与服务器通信，但服务器找不到请求的内容。

确保您的网址有效，尝试将您的链接放在浏览器中，看看是否正确，如果您请求的网址有特殊的标题 谷歌浏览器上有一个有用的扩展名为 PostMan 您可以根据需要添加标题并测试 url

使用 IIS 附加所有权限。 控制面板 -> 打开和关闭 Windows 功能
