[ERROR] - JSON POST BODY

Is this a question?

When using it with express server and trying to post json body, it seems like anything above 1KB since request fails. I tried using express.json() middle also body parser but it does not seem to go along smoothly with the proxy middleware. Any help regarding this issue would be helpful. Thanks in advance for the time.

this.app .use(this.parseRequestBody.bind(this)) .use(‘*’, apiProxy) .use(express.json()) .listen(proxyPort);

Is this a bug report?

Yes

Is this a feature request?

No

• http-proxy-middleware: 1.0.4
• http-proxy-middleware configuration { // This value is not used but this is mandatory. target: proxyPort.toString(), changeOrigin: true, followRedirects: true, preserveHeaderKeyCase: true, pathRewrite: this.rewritePath.bind(this), router: this.rewriteHost.bind(this), onError: function onError(err, _req, _res) { // TODO: In future expose it as a callback. }, onProxyReq: this.onProxyReq.bind(this) }
• server: express
• other relevant modules

(Paste the link to an example project and exact instructions to reproduce the issue.)

I tried this from https://github.com/chimurai/http-proxy-middleware/issues/320#issuecomment-600470764 and it worked for me.

You just need to reorder the middlewares; put bodyParser after all proxy middlewares and routes without proxy after bodyParser ex:

app.use('/proxy/routex', myProxy);
app.use('/proxy/routey', myProxy);

... //then, after all proxys
app.use(bodyParser.json());

//and now, all no proxy routes
app.use('/api', (req,res)=>{
//TODO
});

app.get('/api/test', (req,res)=>{
//TODO
});

@chimurai @geoangelotti Sorry for the delay in responding. Back i already had in that order even after that it was causing me issues, for me it was a specific issue of post body being greater than 1KB. For some reason something was adding a header i had to delete below headers before passing the request object to the proxy middleware and everything worked fine after that. delete req.headers[‘expect’] delete req.rawHeaders[‘expect’]
