我试图从Web API获取PDF文档,并希望在Angular App中显示.获取“无法加载PDF文档错误”.
我跟着
“ AngularJS: Display blob (.pdf) in an angular app”发布.
然而,我可以通过关注“ Download file from an ASP.NET Web API method using AngularJS”帖子成功下载相同的文件.

看起来我得到的文件是“Chunked Transfer Encoded”.不知何故,当尝试在角度应用程序中显示时,这不会被解码.请指教.
Web API代码:
HttpResponseMessage result = null; var localFilePath = @"C:\Test.pdf"; if (!File.Exists(localFilePath)) { result = Request.CreateResponse(HttpStatusCode.Gone); } else {// serve the file to the client result = Request.CreateResponse(HttpStatusCode.OK); result.Content = new StreamContent(new FileStream(localFilePath,FileMode.Open,FileAccess.Read)); result.Content.Headers.ContentDisposition = new System.Net.Http.Headers.ContentDispositionHeaderValue("attachment"); result.Content.Headers.ContentType = new MediaTypeHeaderValue("application/pdf"); result.Content.Headers.ContentDisposition.FileName = "Test.pdf"; result.Content.Headers.Add("x-filename","Test.pdf"); } return result;
角度控制器:
myModule.controller("pdfviewerController",function ($scope,$http,$log,$sce) { $http.post('/api/Sample/GetTestFile',{responseType:'arraybuffer'}) .success(function (response) { var file = new Blob([response],{ type: 'application/pdf' }); var fileURL = URL.createObjectURL(file); $scope.content = $sce.trustAsResourceUrl(fileURL); }); });
HTML模板:
<embed ng-src="{{content}}" style="width:200px;height:200px;"></embed>
控制器中存在问题.
{responseType:’arraybuffer’}非常需要.
对于$http.get – 它应该是第二个参数.
对于$http.post – 它应该是第三个参数.

在上面的例子中,我使用$http.post并且我已经通过{responseType:’arraybuffer’}作为第二个参数.
$http.post(‘/ api / Sample / GetTestFile’,{responseType:’arraybuffer’})
更正了代码
$http.post(‘/ api / Sample / GetTestFile’,”,{responseType:’arraybuffer’})
