ファイル添付とかmultipartで送信されてくることがあるので、そのパース方法。
busboyというライブラリを次のように使うことで実現可能。
eventはlambda関数の入力。
if (event.headers['content-type'] && (event.headers['content-type'] as string).includes('multipart/form-data')) {
console.log('IT IS MULTIPART');
const input: CreateMeProfileInput = {};
const busboy = new Busboy({
headers: event.headers,
defCharset: 'utf8'
});
return new Promise((resolve, reject) => {
busboy.on('file', (fieldname: any, file: any, filename: any, encoding: any, mimetype: any) => {
console.log('File [' + fieldname + ']: filename: ' + filename + ', encoding: ' + encoding + ', mimetype: ' + mimetype);
file.on('data', function (data: any) {
util.inspect(data);
console.log(typeof data);
console.log('File [' + fieldname + '] got ' + data.length + ' bytes');
});
file.on('end', function () {
console.log('File [' + fieldname + '] Finished');
});
});
busboy.on('field', function (fieldname: string, value: any, fieldnameTruncated: any, valTruncated: any, encoding: any, mimetype: any) {
console.log(util.inspect(value));
console.log(value.toString('utf8'));
console.log('Field [' + fieldname + ']: value: ' + util.inspect(value) + ` encoding:${encoding}, valTruncated:${valTruncated}, mimetype:${mimetype}`);
});
busboy.on('finish', () => {
console.log('Done parsing form!');
console.log(input);
resolve(input);
});
// @ts-ignore
busboy.on('error', (err) => {
console.log('busboy parse error');
console.log(input);
reject(err);
});
busboy.write(event.body); // 第二引数いらない
busboy.end();
});
}
