Paynow API运行良好，但当它重定向到/真实路由时，会给出错误
｛quot；statusCode"：415，"code"："FST_ERR_CTP_INVALID_MEDIA_TYPE"，"error"："不支持介质类型"消息"："不支持的媒体类型：application/x-www-form-urlencoded"｝
我认为这与fastify有关，真的不知道，因为这是我与fastify的第一个项目。任何帮助都将通知
Fastify，开箱即用，只解析application/json负载。
要管理表单，您需要将这些插件添加到您的项目中
- 快速表单体管理
application/x-www-form-urlencoded - fastify multipart管理
multipart/form-data(又称文件上传(
为了完整性，我需要除这两个之外的东西(我需要multipart/related(。您可以在Fastify实例上使用"addContentTypeParser"添加自己的内容类型解析器。

Fastify推荐@Fastify/formbody-plugin解析x-www-form-urlencoded实体。
通过npm安装：
npm i @fastify/formbody
ES6
import fastify from 'fastify'
import formbody from '@fastify/formbody'
const app = fastify({ logger: false });
app.register(formbody)
ES5
const fastify = require('fastify')()
fastify.register(require('@fastify/formbody'))
