php curl设置header的方法：首先初始化浏览器；然后设置浏览器，并把参数url传到浏览器的设置当中；接着以字符串形式返回到浏览器当中，并判断data是否有数据；最后通过“curl_setopt”方法设置header头即可。
PHP使用CURL设置header头传参以及设置Content-Type: application/json类型的后台数据接收
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
$url = "http://desk.yunindex.cn/test";$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);
后台接受
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"HTTP_ACCEPT": "application\/json", "HTTP_CONTENT_LENGTH": "40","HTTP_CONTENT_TYPE": "application\/json","HTTP_HOST": "desk.yunindex.cn","SCRIPT_FILENAME": "\/workspace\/php\/index_desk\/htdocs\/index.php","REDIRECT_STATUS": "200","SERVER_NAME": "desk.yunindex.cn","SERVER_PORT": "80","SERVER_ADDR": "192.168.1.90","REMOTE_PORT": "64524","REMOTE_ADDR": "192.168.1.113","SERVER_SOFTWARE": "nginx\/1.15.2","GATEWAY_INTERFACE": "CGI\/1.1","REQUEST_SCHEME": "http","SERVER_PROTOCOL": "HTTP\/1.1","DOCUMENT_ROOT": "\/workspace\/php\/index_desk\/htdocs","DOCUMENT_URI": "\/index.php","REQUEST_URI": "\/test","SCRIPT_NAME": "\/index.php","CONTENT_LENGTH": "40","CONTENT_TYPE": "application\/json","REQUEST_METHOD": "POST","QUERY_STRING": "","FCGI_ROLE": "RESPONDER","PHP_SELF": "\/index.php","REQUEST_TIME_FLOAT": 1557025085.410574,"REQUEST_TIME": 1557025085}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
结果
string(40) "{"accountid":"34","option":"chat_index"}"
