我是新来的角的js，我希望在浏览器的新窗口中打开PDF文档后pressing一个按钮。

I'm new to angular js and I wish to open a PDF document in a new window of the browser after pressing a button.

我做与 $ http.get（）在前端的GET请求，在后端有一个Java休息服务，以响应GET并生成一个PDF文件。我想打开这个PDF浏览器。

I make a GET request with $http.get() at front end, at backend there is a Java rest service that respond to the GET and generates a PDF. I wish to open this PDF on the browser.

如果无法打开这样的PDF则至少打开带有AngularJs任何PDF，我怎么能这样做呢？

If is not possible to open the PDF in this way then at least open any PDF with AngularJs, how could I do this?

@GET
@Path("/printPdf")
public Response printService(){

//generates the pdf

File reportFile = new File(filePath);
String name = reportName + "." + "pdf";
ResponseBuilder response = Response.ok(new     TemporaryFileInputStream(reportFile));
response.header("Content-Disposition", "attachment; filename=" + name);
response.header("Content-Type", "application/pdf");
response.header("Access-Control-Expose-Headers", "x-filename");
response.header("x-filename", name);

return response.build();
}

这是什么有一个在后台生成在休息服务的响应。

this is what there is at backend to generate the response in the rest service.

推荐答案

如果你有这样的事情：

var myPdfUrl = 'something'
$http.get(myPdfUrl);

做到这一点，而不是：

Do this instead:

var myPdfUrl = 'something'  
$window.open(myPdfUrl);

如果相反，你有这样的事情：

If instead you have something like this:

$http
    .get(generatePdfUrl)
    .success(function(data){
        //data is link to pdf
    });     

做到这一点：

$http
    .get(generatePdfUrl)
    .success(function(data){
        //data is link to pdf
        $window.open(data);
    });
