Javascript 保存PDF响应的原始响应/二进制数据

我在node中得到一个响应，以获取一个PDF，我希望保存二进制数据并将其上载到S3，然后出于历史目的，我可以随心所欲地提取它。现在我在尝试提取PDF原始数据/二进制数据时遇到了问题，因此我可以将其保存为PDF并上传，我想我离此越来越近了。这是我得到的回应。身体

这是我的代码：

platform.on(platform.events.loginSuccess, async function(e) {
    let resp = await platform.get('/restapi/v1.0/account/~/extension/'+accountId+'/message-store', {
        messageType: ['Fax'],
        dateFrom: ['2021-05-01'],
        dateTo: ['2021-05-16']


    })
    let jsonObj = await resp.json()
    let attachId = jsonObj.records[0].id

    let getMessageContent = await platform.get('/restapi/v1.0/account/~/extension/'+accountId+'/message-store/'+attachId+'/content/'+attachId, {
        contentDisposition: ['Inline']
    })

我知道我得到的回复是正确的，因为如果我在postman中运行该URL并使用预览选项，我可以看到pdf（参见屏幕截图）。我错过了什么

这对我来说很合适。response.body是一个包含二进制数据的可读文件，我猜Postman会自动读取此流并显示结果

好消息是，这种类型的流正是S3在上传文件时作为请求主体所需要的，这意味着您无需将其保存在任何地方—您只需将其直接传递给S3即可。根据您的实现，您的代码可能如下所示：

const result=wait s3Client.upload({
水桶：“我的水桶”，
关键字：“myfilename.pdf”，
Body:response.Body，
}).promise（）
