Why are my post requests sended twice?
See original GitHub issueI send post request like:
Vue.http.post(url, {}, {params:data}).then(callback)
I make the second param in post method a empty object because I don’t want to send JSON data.
In chrome’s devtool, I record the network data, and I notice that there are two requests sended when I called post method. One of them has a ‘Request Method’ attribute whose value is ‘OPTIONS’.

That’s called a preflight request that allows the server to specify what is required for that request to be fulfilled.
It’s CORS related and is not an issue.
Is there any explanation for as to why the pre-flight request also registers as a normal request to the server and overall the process of sending a request to the server via Vue JS method registers as 2 requests on the server and a request sent via jQuery ajax or separately via Postman registers as 1 request?
