需要可配置bodyParser的limit

[qjekingstar]

默认的是100k， 希望能改成可配置的，谢谢

let bodyParserMethd = bodyParser.json({ limit });
const contentType = req.get('Content-Type');
if (contentType === 'text/plain') {
	bodyParserMethd = bodyParser.raw({limit,  type: 'text/plain' });
} else if (contentType === 'text/html') {
	bodyParserMethd = bodyParser.text({limit, type: 'text/html' });
} else if (contentType === 'application/x-www-form-urlencoded') {
	bodyParserMethd = bodyParser.urlencoded({ limit, extended: false });
}
