fastify-multipart crashes服务

Question

我正在尝试让一个多部分POST与fastify-multipart一起工作，但每当我将一个多部分文件发布到端点时，我的服务就会崩溃，并显示以下错误：

req.raw[kMultipart] = true
                      ^

TypeError: Cannot set property 'Symbol(multipart)' of undefined
    at Parser.setMultipart [as fn] (/service/node_modules/fastify-multipart/index.js:24:23)
    at ContentTypeParser.run (/service/node_modules/fastify/lib/contentTypeParser.js:103:27)
    at handleRequest (/service/node_modules/fastify/lib/handleRequest.js:35:39)
    at onRunMiddlewares (/service/node_modules/fastify/lib/middleware.js:22:5)

    at xXssProtection (/service/node_modules/x-xss-protection/dist/index.js:47:13)
    at Holder.done (/service/node_modules/middie/middie.js:112:11)

    at Holder.done (/service/node_modules/middie/middie.js:112:11)
    at xDownloadOptionsMiddleware (/service/node_modules/ienoopen/index.js:5:5)

我是不是遗漏了一个依赖项或类似的东西？

"fastify": "^2.0.0",
"fastify-multipart": "^4.0.6",

在index.js中，代码如下：

const kMultipart = Symbol('multipart')

function setMultipart (req, payload, done) {
  // nothing to do, it will be done by the Request.multipart object
  req.raw[kMultipart] = true
  done()
}

req.raw似乎是未定义的。

只有fastify-multipart v1与fastify v2兼容

请注意，v3和更高版本的API完全不同，因此您需要更新您的fastify版本或降级您的插件，并更改有效负载管理。
