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"}"
