获取谷歌搜索结果的数量 [英] get number of google search results

问题描述

我经常搜索使用java检索谷歌搜索结果的数量，但没有任何效果。
我也尝试过Google Custom Search API。
我不想要结果的标题/网址，只是找到的总结果数。
有人可以指导我吗？

I searched a lot to retrieve the number of search results in google using java, but nothing worked. I have tried Google Custom Search API aswell. I don't want the title/url of results, just number of total results found. Can some one please guide me?

推荐答案

使用自定义搜索API，你就是正确的方式。

By using the Custom Search API, you're on the right way.

totalResults 键您从查询中获得的custom-search / v1 / using_rest #WorktingResultsrel =noreferrer>响应JSON 。只需抓住它的价值即可。

There's a totalResults key in the response JSON that you get from your query. Just grab it's value and you're done.

如果您希望JSON仅包含该值，请添加 fields 您的查询参数如下：

If you want your JSON to only contain that value, add the fields parameter to your query like that:

https://www.googleapis.com/customsearch/v1?key={YOUR_API_KEY}&cx={YOUR_SEARCH_ENGINE_ID}
    &q={YOUR_SEARCH_STRING}&alt=json&fields=queries(request(totalResults))
