Angularjs中的下載文件無法正確保存

我的Web API方法要麼返回具有多個文件的單個文件或zip文件。這是Web API的實現。Angularjs中的下載文件無法正確保存

 public HttpResponseMessage Download([FromUri] List<string> fileNames) 
 
     { 
 
      try 
 
      { 
 
       HttpResponseMessage result = new HttpResponseMessage(HttpStatusCode.OK); 
 
       if (fileNames.Count > 1) 
 
       { 
 
        List<string> filePaths = new List<string>(); 
 
        
 
        MemoryStream memoryStreamOfFile = new MemoryStream(); 
 

 
        using (ZipFile zip = new ZipFile()) 
 
        { 
 
         foreach (var fileName in fileNames) 
 
         { 
 
          zip.AddFile(HttpRuntime.AppDomainAppPath + @"\Uploaded\" + fileName); 
 
         } 
 
         zip.Save(memoryStreamOfFile); 
 
         memoryStreamOfFile.Seek(0, SeekOrigin.Begin); 
 
         result.Content = new StreamContent(memoryStreamOfFile); 
 
         result.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment"); 
 
         result.Content.Headers.ContentDisposition.FileName = "files.zip"; 
 
         result.Content.Headers.ContentType = 
 
          new MediaTypeHeaderValue("application/octet-stream"); 
 
         return result; 
 
        } 
 
       } 
 

 
       if (!string.IsNullOrEmpty(fileNames[0])) 
 
       { 
 
        string filePath = HttpRuntime.AppDomainAppPath + @"\Uploaded\" + fileNames[0]; 
 
        
 
        var stream = new FileStream(filePath, FileMode.Open, FileAccess.Read); 
 
        result.Content = new StreamContent(stream); 
 
        result.Content.Headers.ContentType = 
 
         new MediaTypeHeaderValue("application/octet-stream"); 
 
        return result; 
 
       } 
 
       return this.Request.CreateResponse(HttpStatusCode.NotFound, "File not found."); 
 
      } 
 
      catch (Exception ex) 
 
      { 
 
       return this.Request.CreateResponse(HttpStatusCode.InternalServerError, ex); 
 
      } 
 
     }

這種方法完全正常工作，很好，我敢肯定，因爲當我要求通過「高級REST客戶端」，谷歌的Chrome擴展這種方法，文件被下載和完美的作品。

但是，當我通過Angularjs服務調用請求此方法時，文件無法打開。圖像文件給我下面的錯誤

以下爲PDF

，預計下對於ZIP

從Advance Rest Client行爲，但不能與Angularjs 。以下是我的角碼

"download": { 
 
     method: "GET", 
 
     url: "api/files/Download/", 
 
     params: { fileNames: "@fileNames" }, 
 
     responseType: "arraybuffer", 
 
     headers: { 
 
      'Content-Type': "application/octet-stream" 
 
     } 
 
}

return fileManagerClientService.download({ fileNames: fileName }) 
 
       .$promise 
 
       .then(function (data) { 
 
        
 
        console.log(data); 
 
        appInfo.setInfo({ message: "files downloaded successfully" }); 
 

 
        try { 
 
         var blob = new Blob([data]); 
 

 
         if (typeof (fileName) == "string") 
 
          FileSaver.saveAs(blob, fileName); 
 
         else 
 
          FileSaver.saveAs(blob, "AllFiles.zip"); 
 

 
        } catch (ex) { 
 
         console.log(ex); 
 
        } 
 
       },

請告訴我什麼，我缺少的角邊？我已經嘗試了很多代碼片段，但它們不起作用！

所以，夥計們，通過用$ http調用替換$ resource解決了這個問題。這裏是工作的代碼，

function download(fileName) { 
 
      appInfo.setInfo({ busy: true, message: "loading files" }); 
 
      
 

 
      return $http({ 
 
       method: "GET", 
 
       url: "api/files/Download/", 
 
       params: { fileNames: fileName }, 
 
       responseType: "arraybuffer" 
 
      }).then(function (data) { 
 
       appInfo.setInfo({ message: "files downloaded successfully" }); 
 

 
       try { 
 
        var blob = new Blob([data.data]); 
 

 
        if (typeof (fileName) == "string") 
 
         FileSaver.saveAs(blob, fileName); 
 
        else 
 
         FileSaver.saveAs(blob, "AllFiles.zip"); 
 

 
       } catch (ex) { 
 
        console.log(ex); 
 
       } 
 
      }, function (error) { 
 

 
      }); 
 
     }

這是工作的代碼，我希望有人會使用$資源有一個更好的解決方案，爲什麼它不與$資源工作呢。
