koa-wechat-xml-body

为 koa 解析 xml 请求

Usage

const koa = require('koa')
const xmlParser = require('koa-wechat-xml-body')

const app = koa()
app.use(xmlParser())

app.use(function(ctx, next) {
    // the parsed body will store in this.request.body
    // if nothing was parsed, body will be undefined
    ctx.body = ctx.request.body
    return next()
})

Options

• encoding: requested encoding. Default is utf8. If not set, the lib will retrive it from content-type(such as content-type:application/xml;charset=gb2312).
• limit: limit of the body. If the body ends up being larger than this limit, a 413 error code is returned. Default is 1mb.
• length: length of the body. When content-length is found, it will be overwritten automatically.
• onerror: error handler. Default is a noop function. It means it will eat the error silently. You can config it to customize the response.
• xmlOptions: options which will be used to parse xml. Default is {}. See xml2js Options for details.
• key: A chance to redefine what the property name to use instead of the default body (ctx.request.body).

app.use(xmlParser({
    limit: 128,
    encoding: 'utf8', // lib will detect it from `content-type`
    xmlOptions: {
        explicitArray: false
    },
    key: 'xmlBody', // lib will check ctx.request.xmlBody & set parsed data to it.
    onerror: (err, ctx) => {
        ctx.throw(err.status, err.message);
    }
}))
