PHP 实现get 和 Post 请求

1 get

get请求比较简单，file_get_contents()；即可实现

$tmpUrl = "http://测试url";
# get方法获取信息
$rawGetData = file_get_contents($tmpUrl);
# 如果file_get_contents 获取的数据是json格式，可以将json 转换成数组,方便后续解析
$dataArr =  json_decode($rawGetData, true);

2 Post

    class http_Method{
       # 发送post请求
       # $url post请求的地址，$postData array
       public static function httpPost($postData,$url){
           $tmpData='';
           foreach ($postData as $k=>$v)
           {
               $tmpData .= "$k=".urlencode($v)."&";
           }

         $data=substr($tmpData,0,-1);
         $ch=curl_init();
         curl_setopt($ch, CURLOPT_POST, 1);
         curl_setopt($ch, CURLOPT_HEADER, 0);
         curl_setopt($ch, CURLOPT_URL,$url);
         curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
         $result = curl_exec($ch);
         return $result;

       }
}
