import requestsif __name__ == ‘__main__‘:    #基本用法    #response = requests.get("http://httpbin.org/get")    #print(response.text)    #帶參數的get    #data = {    #    "name":"wu",    #    "age":21    #}    #response = requests.get("http://httpbin.org/get",params=data)    #print(response.text)    #解析json    #print(response.json)    #擷取二進位資訊    #response = requests.get("http://github.com/favicon.ico")    #print(response.content)    #with open("favicon.ico","wb") as f:    #    f.write(response.content)    #    f.close()    #添加headers    #headers = {    #    "User-Agent":"Mozilla/5.0 (Windows NT 10.0; Win64; x64)"    #}    #response = requests.get("http://www.zhihu.com/explore",headers = headers)    #print(response.text)    #post請求    #data = {    #    "name":"wu",    #    "age":21    #}    #headers = {    #    "User-Agent":"Mozilla/5.0 (Windows NT 10.0; Win64; x64)"    #}    #response = requests.post("http://www.httpbin.org/post",data = data,headers = headers)    #狀態代碼判斷    #response = requests.get("http://www.baidu.com")    #exit() if not response.status_code == requests.codes.ok else print("OK")    #檔案上傳    #...    #cookie    #...    #會話維持(類比登陸驗證)    #s = requests.Session() #相當於在一個瀏覽器中    #s.get("http://httpbin.org/cookies/set/number/123456789")    #response = s.get("http://httpbin.org/cookies")    #print(response.text)    #認證驗證(https)    #response = get("http://www.12306.cn",verify = False)    #print(response.status_code)    #指定認證...    #代理    #proxies = {    #    "http":    #    "https"    #}    #response = requests.get("http://www.12306.cn",proxies = proxies)    #逾時設定    #認證設定
