我必须制作一个能够将 Bing 搜索 API（SOAP 服务）与 java 一起使用的应用程序。它必须对单词进行特定搜索。这是我的代码：
import com.google.code.bing.search.client.BingSearchClient;
import com.google.code.bing.search.client.BingSearchServiceClientFactory;
import com.google.code.bing.search.client.BingSearchClient.SearchRequestBuilder;
import com.google.code.bing.search.schema.AdultOption;
import com.google.code.bing.search.schema.SearchOption;
import com.google.code.bing.search.schema.SearchRequest;
import com.google.code.bing.search.schema.SearchResponse;
import com.google.code.bing.search.schema.SourceType;
import com.google.code.bing.search.schema.web.WebResult;
import com.google.code.bing.search.schema.web.WebSearchOption;
public class MyApp {
String apikey = "****************";
String searchword="google";
public static void main(String[] args){
BingSearchServiceClientFactory factory = BingSearchServiceClientFactory.newInstance();
BingSearchClient client = factory.createBingSearchClient();
SearchRequestBuilder builder = client.newSearchRequestBuilder();
builder.withAppId(apikey);
builder.withQuery(searchword);
builder.withSourceType(SourceType.WEB);
builder.withVersion("2.0");
builder.withMarket("en-us");
builder.withAdultOption(AdultOption.MODERATE);
builder.withSearchOption(SearchOption.ENABLE_HIGHLIGHTING);
builder.withWebRequestCount(10L);
builder.withWebRequestOffset(0L);
builder.withWebRequestSearchOption(WebSearchOption.DISABLE_HOST_COLLAPSING);
builder.withWebRequestSearchOption(WebSearchOption.DISABLE_QUERY_ALTERATIONS);
SearchResponse response = client.search(builder.getResult());
for (WebResult result : response.getWeb().getResults()) {
System.out.println(result.getTitle());
System.out.println(result.getDescription());
System.out.println(result.getUrl());
System.out.println(result.getDateTime());
}
}
}
我找到了这个http://code.google.com/p/bing-search-java-sdk/网站。我从 Azure MarketPlace 获得我的 appkey。我收到一个错误：java.lang.NullPointerException 在将显示响应的 for 循环行。这意味着响应为空。我不明白我错过了什么。
