November 19, 2022 by Tarik

Another way to solve this is to do the following: controller.Request = new HttpRequestMessage(); controller.Request.Properties.Add(HttpPropertyKeys.HttpConfigurationKey, new HttpConfiguration()); If you are upgrading to webapi 5.0, then you’ll need to change this to: controller.Request = new HttpRequestMessage(); controller.Request.SetConfiguration(new HttpConfiguration()); The reason why you need to do this is because you have to have Request populated on the … Read more

What does it mean when an HTTP request returns status code 0?

November 13, 2022 by Tarik

Many of the answers here are wrong. It seems people figure out what was causing status==0 in their particular case and then generalize that as the answer. Practically speaking, status==0 for a failed XmlHttpRequest should be considered an undefined error. The actual W3C spec defines the conditions for which zero is returned here: https://fetch.spec.whatwg.org/#concept-network-error As … Read more

Difference between Pragma and Cache-Control headers?

October 18, 2022 by Tarik

Pragma is the HTTP/1.0 implementation and cache-control is the HTTP/1.1 implementation of the same concept. They both are meant to prevent the client from caching the response. Older clients may not support HTTP/1.1 which is why that header is still in use.

October 6, 2022 by Tarik

I did not know the answer so asked the ASP.NET team here. So the trick is to change the signature to HttpResponseMessage and use Request.CreateResponse.

You can however adapt HttpResponseMessage to IHttpActionResult using the canned response of ResponseMessage. It took me a while to figure this out, so I wanted to post it showing that you don’t necesarily … Read more

Proper way to return JSON using node or Express

September 12, 2022 by Tarik

That response is a string too, if you want to send the response prettified, for some awkward reason, you could use something like JSON.stringify(anObject, null, 3) It’s important that you set the Content-Type header to application/json, too. var http = require(‘http’); var app = http.createServer(function(req,res){ res.setHeader(‘Content-Type’, ‘application/json’); res.end(JSON.stringify({ a: 1 })); }); app.listen(3000); // > … Read more
