Getting the number of google search hits with google api - api

Question

I am trying to get the number of search results with a custum search engine. I tried the following code:
String charset = "UTF-8";
String google = "https://www.googleapis.com/customsearch/v1?key={mykey}" +
"&cx={mycxcode}&q=" +URLEncoder.encode(searchString, charset) +
")&fields=queries(request(totalResults)";
String userAgent = "Mozilla/5.0 (Windows; U; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 2.0.50727)";
String totalResultsElementText = Jsoup.connect(google).userAgent(userAgent).ignoreContentType(true).get().text();
For this code i get the following error message:
org.jsoup.HttpStatusException: HTTP error fetching URL. Status=400, URL={myurl}
What am i doing wrong?

Answer 1

The url you are creating has error. You should change parameter fields to
&fields=queries/request(totalResults), because request is a field of queries, but not an array.
More about partial selectors can be found here.
String charset = "UTF-8";
String google = "https://www.googleapis.com/customsearch/v1?key={mykey}" +
"&cx={mycxcode}&q=" +URLEncoder.encode(searchString, charset) +
"&fields=queries/request(totalResults)";
String userAgent = "Mozilla/5.0 (Windows; U; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 2.0.50727)";
String totalResultsElementText = Jsoup.connect(google).userAgent(userAgent).ignoreContentType(true).get().text();
Your result is in form of JSON so you can extract final value like that:
JSONObject json = new JSONObject(totalResultsElementText);
System.out.println(json.getJSONObject("queries").getJSONArray("request").getJSONObject(0).get("totalResults"));
