远程服务器返回意外响应：(405) Method Not Allowed

Question

我有以下代码：

返回以下异常：

ProtocolException was unhandled by user code

The remote server returned an unexpected response: (405) Method Not Allowed.

我尝试使用以下命令（在命令提示符中使用 Administrator）：

C:\Windows\Microsoft.NET\Framework\v3.0\Windows Communication Foundation>ServiceModelReg.exe -i

然后出现以下内容：

但是，异常仍然存在！

感谢任何建议。

（会不会是 .NET Framework 的原因？）

我尝试了以下方法：

C:\Windows\Microsoft.NET\Framework\v4.0.30319>ServiceModelReg.exe -i

但它返回给我以下内容：

[Error]Switch '-c' requires a component to be specified for installation or uninstallation. Please specify which components to install or uninstall.

感谢任何有用的建议。

添加信息

Customers.aspx.cs

public partial class Services_Customers : System.Web.UI.Page
{

    private System.Data.DataTable countryDataTable = null;

    protected void Page_Load(object sender, EventArgs e)
    {
        // Retrieve DataTable from cache
        countryDataTable =
        (System.Data.DataTable)Cache["Countries"];

    }
    protected void GetCountriesButton_Click(object sender, EventArgs e)
    {

        // Does cached item exist?
        if (countryDataTable == null)
        {

            CustomersClient customersService = new CustomersClient();
            // Retrieve DataTable from WCF Service
            countryDataTable = customersService.GetCountries(StartingLettersTextBox.Text);

            // Save DataTable to cache
            Cache["Countries"] = countryDataTable;

        }

        // Set GridView DataSource
        CustomersGridView.DataSource = countryDataTable;
        CustomersGridView.DataBind();
    }
}

web.config

以下代码在 web.config 文件中的<configuration> 内：

<bindings>
  <basicHttpBinding>
    <binding name="BasicHttpBinding_ICustomers" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true">

尝试将以下行添加到您的 web.config 中。

  <webHttpBinding>
    <binding name="crossDomain" crossDomainScriptAccessEnabled="true" />
  </webHttpBinding>

最终结果如下：

<system.serviceModel>
<bindings>
  <webHttpBinding>
    <binding name="crossDomain" crossDomainScriptAccessEnabled="true" />
  </webHttpBinding>
  <basicHttpBinding>
    <binding name="BasicHttpBinding_ICustomers" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true">
      <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" />
      <security mode="None">
        <transport clientCredentialType="None" proxyCredentialType="None" realm="" />
        <message clientCredentialType="UserName" algorithmSuite="Default" />
      </security>
    </binding>
  </basicHttpBinding>
</bindings>
<client>
  <endpoint address="http://localhost:1112/Services/Customers.svc" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_ICustomers" contract="CustomersService.ICustomers" name="BasicHttpBinding_ICustomers" />
</client>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
</system.serviceModel>

Answer 2

错误是不允许的方法。我在您的代码中没有看到您在代理上设置用户名/密码组合的任何地方......可能就是这样吗？
