PHP主干源码就集成了对libcurl的接口扩展php-src/ext/curl.http://php.net/curlFirefox和Chrome也都提供了对curl的支持,F12开发者工具的网络请求里可以直接把请求复制为cURL命令,主要就是一些头,关键如Cookie信息:curl \u0026#39;https://www.zhihu.com/topic/19552910/newest\u0026#39; \\-H \u0026#39;Host: www.zhihu.com\u0026#39; \\-H \u0026#39;User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:50.0) Gecko/20100101 Firefox/50.0\u0026#39; \\-H \u0026#39;Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8\u0026#39; \\-H \u0026#39;Accept-Language: zh-CN,zh;q=0.8,en-US;q=0.5,en;q=0.3\u0026#39; \\-H \u0026#39;Accept-Encoding: gzip, deflate, br\u0026#39; \\-H \u0026#39;Cookie: name1=value1; name2=value2\u0026#39; \\-H \u0026#39;Connection: keep-alive\u0026#39; \\-H \u0026#39;Upgrade-Insecure-Requests: 1\u0026#39;要实现PHP编程(爬虫,自动化测试),你还可以根据浏览器里得到的命令参数转换为PHP curl代码:http://php.net/curl_setoptCURLOPT_COOKIEFILE:包含 cookie 数据的文件名，cookie 文件的格式可以是 Netscape 格式，或者只是纯 HTTP 头部风格，存入文件。如果文件名是空的，不会加载 cookie，但 cookie 的处理仍旧启用。 CURLOPT_COOKIEJAR:连接结束后，比如，调用 curl_close 后，保存 cookie 信息的文件。使用PHP curl,单进程也可以并行发起多个请求:接口1: php -S 127.0.0.1:8080 -t /home/eechen/www接口2: php -S 127.0.0.2:8080 -t /home/eechen/www/home/eechen/www/index.php:\u0026lt;?phpheader(\u0026#39;Content-Type: application/json; charset=utf-8\u0026#39;);echo json_encode(array(\u0026#39;SERVER_NAME\u0026#39; =\u0026gt; $_SERVER));//串行访问需要sum(2,1)秒,并行访问需要max(2,1)秒.($_SERVER == \u0026#39;127.0.0.1\u0026#39;) ?
