Angular2 http.post gets executed twice

Question

I came across a weird issue where the Angular2\'s (RC1) Http service executes the http.post call twice. I\'ve debugged my app and I know for a fact this is not a click event

Answer 1

The http service returns a cold observable that get executed on every subscribe, you want to convert it to a hot observable that get only executed on the first subscribe and share the same value for subsequent subscribes.

To convert it all you have to do is share it:

return this._http.post(this.createURL(this.getCreateURL(), [], params), body, options)
.map(res => this.handleObjectResponse(res))
.share();
