PHP uses CURL to set header header parameters and set Content-Type: Background data reception of application/json type

CURL function

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;
}

There is a problem here. If you are using nginx, if the parameters in the header are underlined (such as: client_secret), it seems that the parameter cannot be received when using $_SERVER. You need to configure nginx.conf and add underscores_in_headers on; configure

file_get_contents(&#39;php://input&#39;)

to receive parameters and receive them in the form of a stream

string(40) "{"accountid":"34","option":"chat_index"}"
