xmlhttprequest 无法加载响应 URL。对于预检，$http.delete 的 http 状态代码 405 无效

Question

我有网络 API 服务：

public void Delete(int id)
        {
}

Web api-Web.config

<httpProtocol>
      <customHeaders>
        <add name="Access-Control-Allow-Origin" value="*" />
        <add name="Access-Control-Allow-Headers" value="Content-Type" />
        <add name="Access-Control-Allow-Methods" value="GET, POST, PUT, DELETE, OPTIONS" />
      </customHeaders>
    </httpProtocol>
    <validation validateIntegratedModeConfiguration="false" />
    <directoryBrowse enabled="true" />
    <modules runAllManagedModulesForAllRequests="true" />
    <handlers>
      <remove name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" />
      <remove name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" />
      <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
      <add name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness32" responseBufferLimit="0" />
      <add name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness64" responseBufferLimit="0" />
      <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
    </handlers>

当我使用 Postman（Chrome 扩展名）使用它时。我将数据作为 'form data' 传递。我得到 200 return 代码。我已经使用 angularjs:

调用了这个方法

deletesurvey: function(surveyData) {
                var objFormData = new FormData();
                for (var key in surveyData)
                    objFormData.append(key, surveyData[key]);
                return $http.delete(configurationurl + 'Survey', objFormData, {
                    transformRequest: angular.identity,
                    headers: { 'Content-Type': undefined }
                });

我在 Web.Config 中设置了 headers:

<modules runAllManagedModulesForAllRequests="true" />
    <httpProtocol>
      <customHeaders>
        <add name="Access-Control-Allow-Origin" value="*" />
        <add name="Access-Control-Allow-Methods" value="GET,POST,PUT,HEAD,DELETE,OPTIONS" />
        <add name="Access-Control-Allow-Headers" value="Origin, X-Requested-With, Content-Type, Accept" />
        <add name="Access-Control-Request-Methods" value="*" />
        <add name="Access-Control-Max-Age" value="1728000" />

      </customHeaders>
    </httpProtocol>

调用 deletesurvey 函数后出现错误（浏览器是 Chrome） xmlhttprequest 无法加载响应 URL 预检具有无效的 http 状态代码 405

Answer 1

似乎正在发生的事情是 CORS 'preflight' 请求（使用 OPTIONS 方法）由服务器 not/incorrectly 处理。

xmlhttprequest 无法加载响应 URL。对于预检，$http.delete 的 http 状态代码 405 无效

xmlhttprequest cannot load response URL. for preflight has invalid http status code 405 for $http.delete
