新窗口显示PDF的仅控制 ）

任何想法，为什么PDF的内容没有显示？

code：

  $ http.post（'/ fetchBlobURL'，{myParams}）。成功（功能（数据）{

您需要设置的responseType 到 arraybuffer 如果你想创建一个一滴

  $ http.post（'/ fetchBlobURL'，{myParams}，{responseTyp的：arraybuffer'}）
   .success（功能（数据）{
       var文件=新的Blob（[数据] {类型：应用程序/ PDF'}）;

I have been working on this problem for the last few days. With no luck on trying to display the stream on <embed src> tag, I just tried to display it on a new window.

The new window shows pdf controls only )

Any idea why the content of the pdf is not showing?

CODE:

$http.post('/fetchBlobURL',{myParams}).success(function (data) {
    var file = new Blob([data], {type: 'application/pdf'});
    var fileURL = URL.createObjectURL(file);
    window.open(fileURL);
});

解决方案

You need to set the responseType to arraybuffer if you would like to create a blob from your response data:

$http.post('/fetchBlobURL',{myParams}, {responseType: 'arraybuffer'})
   .success(function (data) {
       var file = new Blob([data], {type: 'application/pdf'});
       var fileURL = URL.createObjectURL(file);
       window.open(fileURL);
});
