我遇到问题,我无法从$ http响应的标头中获取文件名

HTTP/1.1 200 OK
Content-Length:121257
Content-Type:application/pdf
服务器:Microsoft-HTTPAPI/2.0
Access-Control-Allow-Origin:*
Access-Control-Expose-Headers:*
Content-Disposition:attachment; filename = Order-414.pdf
日期:星期三,2015年2月11日05:32:25 GMT

我只想在下载时获取文件名(Order-414.pdf)作为pdf名称.但是在这个代码块中:

   $http.get(httpPath, { responseType: 'arraybuffer' })
            .success(function (data, status, headers) {
                debugger;
                // just return content-type
                var header = headers();

header对象只包含content-type.

Object {content-type: "application/pdf"}

我在某处读到我们需要为WebAPI配置CORS:

  private static void RegisterCorsConfig(HttpConfiguration config)
    {
        var cors = new EnableCorsAttribute("*", "*", "*", "*");
        //var cors = new EnableCorsAttribute("*", "*", "*", "DataServiceVersion, MaxDataServiceVersion");
        //cors.ExposedHeaders.Add("*");
        //cors.ExposedHeaders.Add("filename");
        config.EnableCors(cors);
    }

但它仍然无效.请帮我.提前致谢.

我有这样的Odata结果

        {"odata.metadata":"https://localhost/DocTalkMobileWebApiOData/odata/$metadata#MasterPatient/@Element","PatUniqueId":"39e713db-6a0e-4e59-bf7b-033f4fc47ad5",  "PatID":null,
"pat_lname":"White","pat_fname":"Peter","pat_mi":"     ","pat_ssn":"270787655","pat_dob":"08/07/1973","pat_sex":"M","pat_status":null,"priInsID":2,"secInsID":1,"PCPID":1,"InternalDrID":1,"EXPID":1,"EXPDate":"","pat_phone":null,"isNew":true,"imported":true,"byWhom":"dt","lastUpdate":"2011-03-30T09:41:57.36","changeStamp":"AAAAAAAAIUE=","address":"","city":"","state":"","zip":"","currentMcp":"","currentVisitCount":-2,"otherId":"543674","pcpName":null,"hasChanges":true,"ProgramSource":null,"mrnID":"","createdBy":null,"createdDate":"2007-10-26T10:16:15","expLocation":null,"ethnicId":1,"prefLanguageId":1,"raceId":1
    }

我试图通过kendo.ui.datasource得到这个结果:

 newPatient = new kendo.data.DataSource({
        type: 'odata', // <-- Include OData style params on query string.
        transport: {
            read: {
                url: url + '/MasterPatient(guid\'00000000-0000-0000-0000-000000000000\')', // <-- Get data from here
                dataType: "json" // <-- The default was "jsonp"
            },

            parameterMap: function (options, type) {
                var paramMap = kendo.data.transports.odata.parameterMap(options);

                delete paramMap.$inlinecount; // <-- remove inlinecount parameter.
                delete paramMap.$format; // <-- remove format parameter.

                return paramMap;
            }
        },
        schema: {
            data: function (data) {                 
                return data; …

我是Xamarin的新手,在尝试使用Android Emulator运行Xamarin App时遇到困难.

这是我的AVD:

我可以运行这个AVD很好但很慢,如果我检查使用主机GPU,它要快得多,但需要很长时间才能启动模拟器.但是当我在Xamrin上调试时,它总是在模拟器中显示此错误:

unfortunately launcher3 has stopped

或只是加载,永远不会像这样完成:

请帮我.
