Description

We are doing upgrade from httpclient (4.5.13) to httpclient5 (5.2.1).

And after the upgrade, we found when use following sample code to create a post request, the request execution will fail with 400 Bad Request error, because the character "~" in parameter string is not encoded into %7E. If we set the charset for UrlEncodedFormEntity to UTF-8, still hit same issue.

HttpPost request = new HttpPost(strUrl);
List<NameValuePair> parameters = new ArrayList<NameValuePair>();
parameters.add(new BasicNameValuePair("name", "a~b"));
HttpEntity postParams = new UrlEncodedFormEntity(parameters);
request.setEntity(postParams); 

 

While the encoding was working correctly with httpclient (4.5.13).
