calling Bing

Question

Answer 1

Hello,

During PDC 2008, attendees could try building a client to Live Search APIs using WWSAPI. It is not exactly the same as Bing API, but the process is similar. These steps should work :

a) Get AppID from http://www.bing.com/developers/

b) Download metadata by running the command svcutil /t:metadata http://api.search.live.net/search.wsdl?AppID=<YourAppIDHere>, see API Basics for more details.

c) Create service Proxy using the pre-generated template _CreateServiceProxy

d) Fill out SearchRequest structure with a query for the information. Here is an example from PDC lab, change the parameters as needed
 

    // Form search request to Live Search

    SourceRequest srcRequest = { SourceTypeNews,

        0,

        100, // Specifies the number of results to be returned

        NULL,

        NULL,

        NULL,

        0,

        NULL};

 

    SearchRequest request =  { L"YOUR_APPLICATION_ID",

        queryString, // the actual query

        L"en-US",    // local

        SafeSearchOptionsModerate,

        NULL,

        NULL,

        1,

        &srcRequest};

 e) Call to function *_Search() using the structures you have formed
f) The result will be stored in SearchResponse* pointer, which you can parse out. Here is how it was done in the lab:

   // Initializing response structure to where results of the search will be saved

    SearchResponse* response;

 

    // Call operation MSNSearchService.Search

    hr = MSNSearchPortBinding_Search(m_serviceProxy, &request, &response, m_heap, NULL, 0, NULL, m_error);

 

   // Parsing and outputing results

    SourceResponse* srcResponse = response->Responses;

    for (unsigned int iResponse = 0; iResponse < response->ResponsesCount; iResponse ++)

    {

        Result* srchResults = srcResponse[iResponse].Results;

        for (unsigned int iResult =0; iResult < srcResponse[iResponse].ResultsCount; iResult ++)

        {

            WCHAR* szTitle = srchResults[iResult].Title;

            OutputSearchResult(szTitle);

        }

    }

Done. Give it a try and if it does not work out, just ask for help here.
