如何使用AngularJS下载二进制文件

下载二进制文件时，设置responseType：

非常重要

app.service('dataService',['$http',function($http) {

    this.downloadFile = function(url) {

        var config = {      
            //SET responseType
            responseType: 'blob',
        };

        return $http.get(url, config);
    } 
]);

如果省略responseType，则XHR API默认将UTF-8编码文本转换为DOMString (UTF-16)，这会损坏PDF，图像和其他二进制文件。

有关详细信息，请参阅MDN Web API Reference - XHR ResponseType

angularjs有一些像fetch（）。blob这样的技术
