angularJS经过post方法下载excel文件

exportData: function (templateId, rowId) {
                var config = {
                    headers: {
                        'Content-Type': 'application/json'
                    },
                    responseType: 'arraybuffer'
                };
                return $http.post(commonSvc.baseURlForDCBulk + 'api/export/' + templateId, rowId, config).then(
                    function (response) {
                        var blob = new Blob([response.data], {type: "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet

"}); var objectUrl = URL.createObjectURL(blob); return objectUrl } ).catch(commonSvc.translateHttpError) }

1.post的方法里要加responseType: 'arraybuffer'参数，否则下载的excel会乱码

2.使用{type: "application/vnd.ms-excel"}的写法，能够保存为xls格式的excel文件（兼容老版本）。而使用“application/vnd.openxmlformats-officedocument.spreadsheetml.sheet”则会保存为xlsx

3.返回结果为下载excel文档连接，使用window.open(result)便可

指定文件名的方法：

var saveExcelFile = (function () {
                        var a = document.createElement("a");
                        document.body.appendChild(a);
                        a.style = "display: none";
                        return function (data, fileName) {
                            var blob = new Blob([data], {type: "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"}),
                                url = window.URL.createObjectURL(blob);
                            a.href = url;
                            a.download = fileName;
                            a.click();
                            window.URL.revokeObjectURL(url);
                        };
                    }());
                    var fileName = self.exportTableDataList.DisplayName;
                    saveExcelFile(result, fileName);
