java - RestEasy : How to send an easy POST request with parameters and api key -


i'm beginner , i'm little bit lost resteasy

i'd send post request url similar : http://myurl.com/options?value=3name=picture

string myvalue = "3"; string myname = "picture"; string key = "topsecret";

i'm not sure what's coming. i've seen several tutorial classes (not clear me) , way similar this

final multivaluedmap<string, object> queryparams = new multivaluedmapimpl<>(); queryparams.add("value", myvalue); queryparams.add("name", mypicture); final resteasyclient client = new resteasyclientbuilder().build(); final resteasywebtarget target = client.target(url).queryparams(queryparams);; final builder builder = target.request();

when write have loads of warning. right way ? api key ?

first of all, must check documentation of api want consume regarding how api key must sent server. not apis follow same approach.

for example purposes, let's assume api key must sent in x-api-key header. it's non standard , i've made demonstrate how use client api.

so can have following:

// create client client client = clientbuilder.newclient();  // define target webtarget target = client.target("http://myurl.com/options")                          .queryparam("value", "3")                          .queryparam("name", "picture");  // perform request target response response = target.request().header("x-api-key", "topsecret")                           .post(entity.text(""));  // process response // part  // close response response.close();  // close client client.close();

the above code uses jax-rs api, implemented resteasy. you'd better use client instead of resteasyclient whenever possible ensure portability other implementations.

the above code assumes want send empty text in request payload. modify accordingly.

response instances contain un-consumed entity input stream should closed. typical scenarios response headers , status code processed, ignoring response entity.

going beyond scope of question, bear in mind client instances heavy-weight objects manage underlying client-side communication infrastructure. hence initialization disposal of client instance may rather expensive operation.

the documentation advises create small number of client instances , reuse them when possible. states client instances must properly closed before being disposed avoid leaking resources.

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
