pdfmake + AngularJS + Electron 创建 _blank pdf

Question

我在 AngularJS 和 Electron 中使用库 pdfmake 时遇到问题。 pdf保存为空白。

代码是：

.service('PDFService', function() {

   this.createPdfOne = function(data) {

    const {dialog} = require('electron').remote;
    const choice = dialog.showOpenDialog({ properties: [ 'createDirectory', 'openDirectory']});
    var docDefinition = {
        content: [
            'First paragraph',
            'Another paragraph, this time a little bit longer to make sure, this line will be divided into at least two lines'
        ]
    };

    var fs = require('fs');
    pdfMake.createPdf(docDefinition).getBuffer(function(result) {
        fs.writeFileSync(choice + '/sample.pdf', result);
    });
  };

});

更新：已修复问题

我使用：

pdfMake.createPdf(docDefinition).download()

代替：

 var fs = require('fs');
    pdfMake.createPdf(docDefinition).getBuffer(function(result) {
        fs.writeFileSync(choice + '/sample.pdf', result);
 });

repo documentation 没有提到这一点，但发现here 提出了同样的问题。关闭时说您可以执行以下操作：

pdfMake.createPdf(docDefinition).download('FILENAME.pdf');
