[Python知识库]学习笔记：百度和360关键字提交

2. 搜索引擎关键字提交接口

• 百度的关键词接口
  http://www.baidu.com/s?wd=关键字
• 360的关键词接口
  http://www.so.com/s?q=关键字

3. 实例代码

原理就是使用 requests.get函数，将url进行网址和搜索关键字的拼接。

其中python的字典可以理解为java中的键值对。学了几节课程，高频听到字典这个词。实际代码也经常出现。例如params = {‘params’: baidu}。 requests.get中的可选参数也是要求传入字典类型数据

import requests
def searchBaidu():
    try:
        # 百度搜索关键字的键值对
        baidu = {'wd': 'Python'}
        params = {'params': baidu}
        # 拼接字符串：http://www.baidu.com/s?wd=关键字
        r = requests.get("http://www.baidu.com/s", **params)
        r.raise_for_status()
        r.encoding = r.apparent_encoding
        print('searchBaidu')
        print(r.status_code)
        print(r.url)
        print(len(r.text))
    except:
        print("爬取失败:status_code", r.status_code, r.request.headers)

def search360():
    try:
        # 360搜索关键字的键值对
        s360 = {'q': 'Python'}
        params = {'params': s360}
        # 拼接字符串：http://www.so.com/s?q=关键字http://www.so.com/s?q=关键字
        r = requests.get("http://www.so.com/s", **params)
        r.raise_for_status()
        r.encoding = r.apparent_encoding
        print('search360')
        print(r.status_code)
        print(r.url)
        print(len(r.text))
    except:
        print("爬取失败:status_code", r.status_code, r.request.headers)

if __name__ == '__main__':
    searchBaidu()
    search360()
