    copied!<p>I'm having trouble using Google's freebase API in my java code. As it appears, my query is too large to send it in a GET method but I couldn't find a way to send it as a POST.</p> <p>This is the error I'm getting:</p> <pre><code> com.google.api.client.googleapis.json.GoogleJsonResponseException: 414 Request-URI Too Large &lt;!DOCTYPE html&gt; &lt;html lang=en&gt; &lt;meta charset=utf-8&gt; &lt;meta name=viewport content="initial-scale=1, minimum-scale=1, width=device-width"&gt; &lt;title&gt;Error 414 (Request-URI Too Large)!!1&lt;/title&gt; &lt;style&gt; *{margin:0;padding:0}html,code{font:15px/22px arial,sans-serif}html{background:#fff;color:#222;padding:15px}body{margin:7% auto 0;max-width:390px;min-height:180px;padding:30px 0 15px}* &gt; body{background:url(//www.google.com/images/errors/robot.png) 100% 5px no-repeat;padding-right:205px}p{margin:11px 0 22px;overflow:hidden}ins{color:#777;text-decoration:none}a img{border:0}@media screen and (max-width:772px){body{background:none;margin-top:0;max-width:none;padding-right:0}} &lt;/style&gt; &lt;a href=//www.google.com/&gt;&lt;img src=//www.google.com/images/errors/logo_sm.gif alt=Google&gt;&lt;/a&gt; &lt;p&gt;&lt;b&gt;414.&lt;/b&gt; &lt;ins&gt;That’s an error.&lt;/ins&gt; &lt;p&gt;The requested URL &lt;code&gt;/freebase/v1/mqlread&lt;/code&gt;... is too large to process. &lt;ins&gt;That’s all we know.&lt;/ins&gt; at com.google.api.client.googleapis.json.GoogleJsonResponseException.from(GoogleJsonResponseException.java:143) at com.google.api.client.googleapis.json.GoogleJsonResponseException.execute(GoogleJsonResponseException.java:187) at com.google.api.client.googleapis.services.GoogleClient.executeUnparsed(GoogleClient.java:279) at com.google.api.client.http.json.JsonHttpRequest.executeUnparsed(JsonHttpRequest.java:207) at com.huawei.mdf.MQLReadService.doMqlRead(MQLReadService.java:67) at com.huawei.mdf.MQLReadService.main(MQLReadService.java:82) </code></pre> <p>Here's the code:</p> <pre><code>public void doMqlRead(String id, QueryType queryType) { HttpTransport httpTransport = new NetHttpTransport(); JsonFactory jsonFactory = new JacksonFactory(); HttpRequestInitializer httpRequestInitializer = new HttpRequestInitializer() { @Override public void initialize(HttpRequest arg0) throws IOException { // TODO Auto-generated method stub } }; JsonHttpRequestInitializer requestInitializer = new JsonHttpRequestInitializer() { public void initialize(JsonHttpRequest jsonHttpRequest) throws IOException { FreebaseRequest freebaseRequest = (FreebaseRequest) jsonHttpRequest; freebaseRequest.setPrettyPrint(true); freebaseRequest.setKey(API_KEY); } }; Freebase.Builder fbb = new Freebase.Builder(httpTransport, jsonFactory, httpRequestInitializer); Freebase freebase = fbb.setJsonHttpRequestInitializer( requestInitializer).build(); List&lt;String&gt; queryList = QueryUtil.getQuery(queryType); for (String query : queryList) { query = query.replace("idreplace", id); System.out.println(query.length()); try { Mqlread mqlread = freebase.mqlread(query); mqlread.setIndent(indentation); HttpResponse executeUnparsed = mqlread.executeUnparsed(); String parseAsString = executeUnparsed.parseAsString(); System.out.println(parseAsString); } catch (Exception e) { e.printStackTrace(); } } } </code></pre> <p>I have also tried to change this part in Freebase class (line 450) by switching the <strong>HttpMethod.GET</strong> part into <strong>HttpMethod.POST</strong>, but I'm sure that it's not correct way:</p> <pre><code>/** * Internal constructor. Use the convenience method instead. */ Mqlread(String query) { super(Freebase.this, HttpMethod.GET, REST_PATH, null); this.query = Preconditions.checkNotNull(query, "Required parameter query must be specified."); } </code></pre> <p>Is there a way of doing this?</p>
 

Querying!
