I'm trying to send a POST request to my server (using Apache HTTPClient 4.5) with a set list of JSON parameters. I've followed some SO questions, but am running into problems.
When I use a javascript console to send the request, it works! Like this:
//Using JS console, I send a POST request and it works.
$.post('/createConfigData', {
"tailSign": "A7ALE",
"active": "Y"
});
//Get back 201
When I use Apache HTTPClient 4.5 to try to do the same thing as above, I get back 415 unsupported media type:
HttpPost httppost = new HttpPost('/createConfigData');
String jsondata = "{\"tailSign\": \"A7ALE\",\"active\": \"Y\"}";
StringEntity jsonparam = new StringEntity(jsondata);
jsonparam.setContentType("application/json;charset=utf-8");
jsonparam.setChunked(true);
httppost.addHeader("content-type", "application/x-www-form-urlencoded;charset=UTF-8");
httppost.setEntity(jsonparam);
httpresponse = httpclient.execute(target, httppost);
The data I have from the working request is:
- Request Headers:
- Host: "mysite.com"
- User-Agent: "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:25.0) Gecko/20100101 Firefox/25.0"
- Accept:
"*/*" - Accept-Language: "en-US,en;q=0.5"
- Accept-Encoding: "gzip, deflate"
- Content-Type: "application/x-www-form-urlencoded; charset=UTF-8"
- Referer: "mysite.com/index.html"
- Content-Length: "288"
- Cookie: "JSESSIONID=..."
- Proxy-Authorization: "Basic ..."
- Connection: "keep-alive"
- Pragma: "no-cache"
- Cache-Control: "no-cache"
- Response Headers:
- Age: "0"
- Connection: "Keep-Alive"
- Content-Type: "application/json;charset=UTF-8"
- Date: "Wed, 19 Oct 2016 17:57:34 GMT"
- Server: "Apache-Coyote/1.1"
- Transfer-Encoding: "chunked"
I'm a bit confused on where to set the content type, whether it be the entity or the httppost
=======================
More test cases
Setting httpost's content type to json gives me 400
HttpPost httppost = new HttpPost('/createConfigData');
String jsondata = "{\"tailSign\": \"A7ALE\",\"active\": \"Y\"}";
StringEntity jsonparam = new StringEntity(jsondata);
jsonparam.setChunked(true);
httppost.addHeader("content-type", "application/json;charset=UTF-8");
httppost.setEntity(jsonparam);
httpresponse = httpclient.execute(target, httppost);
Setting httpost's content type to x-www-form-urlencoded gives me 415
HttpPost httppost = new HttpPost('/createConfigData');
String jsondata = "{\"tailSign\": \"A7ALE\",\"active\": \"Y\"}";
StringEntity jsonparam = new StringEntity(jsondata);
jsonparam.setChunked(true);
httppost.addHeader("content-type", "application/x-www-form-urlencoded;charset=UTF-8");
httppost.setEntity(jsonparam);
httpresponse = httpclient.execute(target, httppost);
I also tried adding this line:
httppost.addHeader("Accept", "*/*");
==================
SOLUTION
Using wireshark I was able to figure out that there was an error message that goes along with the 400 bad request! It was just my JSON wasn't correct.
