How does php curl only get data?

php uses CURL to obtain data

The first one, merge POST and GET

function http_curl($url, $type = 'get', $data = ''){
  $cl = curl_init();  //初始化
  curl_setopt($cl, CURLOPT_URL, $url);  //设置 cURL 传输选项
  curl_setopt($cl, CURLOPT_RETURNTRANSFER, 1);  // 将curl_exec()获取的信息以字符串返回,而不是直接输出。
  curl_setopt($cl, CURLOPT_SSL_VERIFYPEER, false);
  curl_setopt($cl, CURLOPT_SSL_VERIFYHOST, false);
  if($type == 'post'){
    curl_setopt($cl, CURLOPT_POST, 1);    //发送 POST 请求,类型为:application/x-www-form-urlencoded
    curl_setopt($cl, CURLOPT_POSTFIELDS, $data);
  }
  $output = curl_exec($cl);  //执行 cURL 会话
  curl_close($cl);
  return $output;
}
Copy after login

The second one is to separate POST and GET

POST

$url = "http://localhost/web_services.php";
  $post_data = array ("username" => "bob","key" => "12345");  
   $ch = curl_init(); 
   curl_setopt($ch, CURLOPT_URL, $url);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  // post数据
  curl_setopt($ch, CURLOPT_POST, 1);
  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
  curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
  // post的变量
  curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data); 
   $output = curl_exec($ch);
  curl_close($ch); 
   //打印获得的数据
  print_r($output);
Copy after login

GET

  //初始化
  $ch = curl_init();  
   //设置选项,包括URL
  curl_setopt($ch, CURLOPT_URL, "http://www.jb51.net");
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_HEADER, 0); 
      curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
      curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
   //执行并获取HTML文档内容
  $output = curl_exec($ch); 
   //释放curl句柄
  curl_close($ch); 
   //打印获得的数据
  print_r($output);
Copy after login

The data obtained in the above method is in json format

Use json_decode($output,true) to parse it into an array; use json_decode($output) to Parsed into an object
