很多站长朋友们都不太清楚php带参数get请求，今天小编就来给大家整理php带参数get请求，希望对各位有所帮助，具体内容如下：
本文目录一览： 1、 php get请求中的请求头应该如何设置 2、 怎么php发送get请求给Java，然后返回想要的具体参数 3、 php 中发送get请求，后台无法获取 php get请求中的请求头应该如何设置获取请求头信息，可以在curl_exec函数执行前，添加代码curl_setopt($ch,CURLINFO_HEADER_OUT,true);在curl_exec函数执行后，通过 curl_getinfo($ch,CURLINFO_HEADER_OUT) 来获取curl执行请求的请求数据。
获取响应头信息，可以在curl_exec函数执行前，添加代码 curl_setopt($ch, CURLOPT_HEADER, true);curl_setopt($ch, CURLOPT_NOBODY,true); 之后 通过curl_exec函数来获取响应头信息。获取设置 curl_setopt($ch, CURLOPT_NOBODY,false);然后对curl_exec获取的值通过\r\n\r\n进行分割截取第一部分即为响应头信息。
怎么php发送get请求给Java，然后返回想要的具体参数curl请求java接口，接口返回值后进行相关操作，给你贴一个curl的代码

php 中发送get请求，后台无法获取针对你说的方式，我分两个来回答，第一种方法，你把后台代码那个echo 'get ok'去掉，然后把前台发送的那个注释去掉，应该就能跳转了；第二种方法，你只是接收了参数，又没有返回任何值，当然判断不了是否又没有接收成功，你应该随便返回一个值，证明代码是能走通的，思路是这样，希望对你有帮助
