我使用 html、js 和 css 构建了一个应用程序。 Web 应用程序的输出是文本或 yaml 文件。我正在输入数据并尝试收集到 yaml 文件中。代码如下:-例如，我希望下载文件中的“PDU”数据是这样的
PDU: PDU_IP: 10.235.250.49 (this is just a sample IP)
当我尝试执行此操作时，它显示[object Object]。我尝试使用 stringify 将对象转换为字符串，但未能实现以下功能。谁能帮我格式化下载的数据。基本上我希望数据采用 YAML 文件中的格式。

看一下这个片段。这主要是您的代码，但我更改了您创建有效负载的部分。
我用 MY CHANGE BEGINS HERE 和 MY CHANGE ENDS HERE 注释标记了我的更改。
它动态添加空格，因此格式如下所示:
PDU:
PDU TEST: BFT
PDU_IP: 185.237.96.51
Product Type:
Protocol Type: iSCSI
Chasis Inputs:
但是，它不适用于您的其余字段，但也许您可以通过创建普通对象并将它们添加到您的数据中来使用它来替换您的黑客空白。

const file = 'formData.yaml';
像这样:
let file = 'test_' + data.PDU['PDU TEST'];
file += '_controller_' + data['Product Type'];
file += '_' + new Date().toISOString().substr(0, 10); // '2020-05-02'
file += '.yaml';
file = prompt('Filename:', file); // to edit manually
