1.建立Custom Search Engine

2.到API key网站 获取 api key

3.测试 api key 搜索

4.搜索参数列表

--------------------

### 1.建立Custom Search Engine ###

得到search engine ID,必须先建立 Custom Search Engine。

我们连到Custom Search Engine control panel 建立Search Engine。

取得Search Engine ID , 把值复制下来

### 2.到API key网站 获取 api key ###

### **3.测试 api key 搜索** ###

有了search engine ID & API key，我们将可采用以下网址搜寻Google 上丰富资料。

网址至少要包含以下三个参数:

key: API key

cx: search engine ID

q: 搜寻的文字

接下来我们就可以在浏览器输入要查询的资料,之后就可以在App中放入查询的API

get 搜索 实例：

[https://www.googleapis.com/customsearch/v1?key=INSERT\_YOUR\_API\_KEY&cx=017576662512468239146:omuauf\_lfve&q=lectures][https_www.googleapis.com_customsearch_v1_key_INSERT_YOUR_API_KEY_cx_017576662512468239146_omuauf_lfve_q_lectures]

其中 [INSERT\_YOUR\_API\_KEY][https_www.googleapis.com_customsearch_v1_key_INSERT_YOUR_API_KEY_cx_017576662512468239146_omuauf_lfve_q_lectures] 换成自己 api key
