我正在AWS Lambda函数中将html转换为docx。将其转换为docx之后，我想将其下载为文件并作为附件发送。但是我无法下载正确的文件。每当我到达终点时。文件已下载，但已损坏。
示例文件下载文件
function htmlToDoc(html) {
const docx = require('html-docx-js').asBlob(html,{
orientation: 'portrait',margins: {
top: 3.17 * 567,right: 1.9 * 567,bottom: 1.9 * 567,left: 1.9 * 567,header: 720 * 567,footer: 1.27 * 567,gutter: 0
}
});
return docx;
}
module.exports.handler = (event,context,callback) => {
try {
const html = `
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Example file</title>
</head>
<body>
All example content goes here
</body>
</html>`;
Promise.resolve(true)
.then(() => {
console.log(html) // It is printing correct html here
return htmlToDoc(html);
})
.then((docx) => {
return callback(null,{
statusCode: 200,headers: {
'access-control-allow-origin': '*','access-Control-Allow-Credentials': true,'Content-type':
'application/vnd.openxmlformats-officedocument.wordprocessingml.document','Content-Disposition': 'attachment; filename="report.docx"'
},isBase64Encoded: true,body: Buffer.from(docx).toString('base64')
});
});
} catch (error) {
console.log('error 1',error);
return createErrorResponse(500);
}
};
