It's a dumb coding mistake.
HttpResponse response = new DefaultHttpClient().execute(new HttpGet(targeturl));
should be
HttpResponse response = new DefaultHttpClient().execute(htg);
Question
I need to use Apache HttpComponents
for its HttpMime
multipart libs. However, when making apparently exactly the same call with HttpComponents
and stock java.net
classes, HttpComponents
fails:
private void getUrl(URI targeturl, String token) throws IOException {
String AUTH = "Authorization";
String OAUTH = "OAuth ";
System.out.println("Impl1:");
HttpGet htg = new HttpGet(targeturl);
htg.addHeader(AUTH, OAUTH + token);
HttpResponse response = new DefaultHttpClient().execute(new HttpGet(targeturl));
System.out.println(response);
String resp = EntityUtils.toString(response.getEntity());
System.out.println(resp);
System.out.println("\nImpl 2:");
HttpURLConnection conn = (HttpURLConnection) uriToUrl(targeturl).openConnection();
conn.setDoOutput(true);
conn.setRequestMethod("GET");
conn.setRequestProperty(AUTH, OAUTH + token);
System.out.print(conn.getResponseCode());
System.out.println(" " + conn.getResponseMessage());
StringWriter writer = new StringWriter();
IOUtils.copy(conn.getInputStream(), writer);
System.out.println(writer.toString());
}
//for known good uris ONLY
private URL uriToUrl(URI uri) {
try {
return uri.toURL();
} catch (MalformedURLException mue) {
throw new Error(mue); //something is seriously fuxxored
}
}
The resulting output is:
Impl1:
HTTP/1.1 401 Unauthorized [Access-Control-Allow-Headers: Authorization, Access-Control-Allow-Methods: POST, GET, PUT, DELETE, OPTIONS, Access-Control-Allow-Origin: *, Content-Length: 51, Content-Type: application/json, Date: Sat, 20 Jul 2013 00:03:42 GMT]
{"status":401,"data":null,"error":["Unauthorized"]}
Impl 2:
200 OK
{"status":200,"data":{...},"error":null}
HttpComponents is client 4.2.5, core 4.2.4, java is 1.6.0-24. The setup appears identical to me, but there must be some difference. What is it?
Solution
It's a dumb coding mistake.
HttpResponse response = new DefaultHttpClient().execute(new HttpGet(targeturl));
should be
HttpResponse response = new DefaultHttpClient().execute(htg);
