比如：
curl_setopt($ch, CURLOPT_HTTPHEADER, 'Content-Type: application/json');
封装CURL函数
public function CurlRequest($url,$data=null,$header=null){
//初始化浏览器
$ch = curl_init();
//设置浏览器，把参数url传到浏览器的设置当中
curl_setopt($ch, CURLOPT_URL, $url);
//以字符串形式返回到浏览器当中
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
//禁止https协议验证域名，0就是禁止验证域名且兼容php5.6
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
//禁止https协议验证ssl安全认证证书
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
//判断data是否有数据，如果有data数据传入那么就把curl的请求方式设置为POST请求方式
if ( !empty($data) ) {
//设置POST请求方式
@curl_setopt($ch, CURLOPT_POST, true);
//设置POST的数据包
@curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
}
//设置header头
if ( !empty($header) ) {
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
}
//让curl发起请求
$str = curl_exec($ch);
//关闭curl浏览器
curl_close($ch);
//把请求回来的数据返回
return $str;
}
函数调用
$url = "http://www.xiaoerhu.com/test";
$jsonArr = [
'accountid' => '34',
'option' => 'chat_index',
];
$jsonStr = json_encode($jsonArr); //设置了Content-Type: application/json，传参要转化为JSON，否则后台接收不到数据
//header头设置
$headers = array(
"Content-Type: application/json",
"Content-Length: " . strlen($jsonStr) . "",
"Accept: application/json",
"client-id:5K8264ILTKCH16CQ2502SI8ZNMTM67VS", //自定义参数
"client-secret:C380BEC2BFD727A4B6845133519F3AD6" //自定义参数
);
$data = $this->CurlRequest($url,$jsonStr,$headers);
后台接收
json_encode($_SERVER)
使用$_SERVER能接收到header头的信息，在header头里面设置的自定义参数会在这里面体现
结果
{
"USER": "www",
"HOME": "/home/www",
"HTTP_CLIENT_SECRET": "C380BEC2BFD727A4B6845133519F3AD6", //这是自定义的参数，跟上面传的参数相对于，会自动转化为大写跟下划线
"HTTP_CLIENT_ID": "5K8264ILTKCH16CQ2502SI8ZNMTM67VS", //这是自定义的参数，跟上面传的参数相对于，会自动转化为大写跟下划线

}
这里有一个问题，如果使用的是nginx的话，header头里的参数如果有下划线（如：client_secret），使用$_SERVER貌似会接收不到该参数，需要配置nginx.conf，在里面添加 underscores_in_headers on; 配置
file_get_contents('php://input')
接收参数，以流的形式接收
