AngularJS使用webApi导出数据

 /////导出功能
 self.importExcel = function () {
 var dataUrl = "http://103.233.7.38:8090/API/_oa/ProjectInfo.asmx/Export";
 $http({
 method: 'post',
 url: dataUrl,
 data: { },
 transformRequest: function (data) {
 return $.param(data);
 },
 headers: {
 'Content-Type': 'application/x-www-form-urlencoded'
 },
 responseType: 'arraybuffer'
 }).success(function (data) {
 var blob = new Blob([data], { type: "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" });
 var da = new Date();
 var fileName = "数据导出" + da.getFullYear() + '-' + (da.getMonth() + 1) + "-" + da.getDate();
 self.saveas(blob, fileName);
 });
 };
 self.saveas = function (blob, fileName) {
 if (window.navigator.msSaveOrOpenBlob) { // For IE:
 navigator.msSaveBlob(blob, fileName+".xlsx");
 } else { // For other browsers:
 var link = document.createElement('a');
 link.href = window.URL.createObjectURL(blob);
 link.download = fileName + ".xlsx";
 link.click();
 window.URL.revokeObjectURL(link.href);
 }
 }
