// handle err
console.log(err)
}
if (data.status == 'verified') {
// mark payment done in your db
}
});
});
Paynow API is working fine but when it redirects to /true route it giving error Paynow API 工作正常，但是当它重定向到 /true 路由时出现错误
{"statusCode":415,"code":"FST_ERR_CTP_INVALID_MEDIA_TYPE","error":"Unsupported Media Type","message":"Unsupported Media Type: application/x-www-form-urlencoded"}
I think it is related to fastify really don't know as it is my first project with fastify.我认为它与 fastify 有关真的不知道，因为这是我第一个使用 fastify 的项目。 Any help will be appricated任何帮助将被应用

For completeness, I needed something other than those two (I needed multipart/related).为了完整起见，我需要这两个以外的东西（我需要多部分/相关）。 You can add your own content type parser using 'addContentTypeParser' on the Fastify instance.你可以在 Fastify 实例上使用 'addContentTypeParser' 添加你自己的内容类型解析器。
