commons httpclient - Adding query string parameters to GET/POST request
Here is how you would add query string parameters using HttpClient 4.2 and later:
URIBuilder builder = new URIBuilder("http://example.com/");builder.setParameter("parts", "all").setParameter("action", "finish");HttpPost post = new HttpPost(builder.build());The resulting URI would look like:
http://example.com/?parts=all&action=finish
If you want to add a query parameter after you have created the request, try casting the HttpRequest to a HttpBaseRequest. Then you can change the URI of the casted request:
HttpGet someHttpGet = new HttpGet("http://google.de");URI uri = new URIBuilder(someHttpGet.getURI()).addParameter("q", "That was easy!").build();((HttpRequestBase) someHttpGet).setURI(uri);
The HttpParams interface isn't there for specifying query string parameters, it's for specifying runtime behaviour of the HttpClient object.
If you want to pass query string parameters, you need to assemble them on the URL yourself, e.g.
new HttpGet(url + "key1=" + value1 + ...);Remember to encode the values first (using URLEncoder).
