1、用file_get_contents()函數(shù)

$params = array('key' => '8d284859d04cfeeea6b0771f754adb49',    'location' => $_COOKIE["lng"].",".$_COOKIE["lat"]);  $url3 = "http://restapi.amap.com/v3/geocode/regeo";  if (strripos('?', $url3)) {  $url4 = $url3 . http_build_query($params); } else {  $url4 = $url3 . '?' . http_build_query($params); }  $ret2 = json_decode(file_get_contents($url4));  var_dump($ret);

2、用php的curl拓展

$url2 = 'http://www.sojson.com/open/api/weather/json.shtml';     $params = array('city' => '長沙');    if (strripos('?', $url2)) {     $url = $url2 . http_build_query($params);      } else {     $url = $url2 . '?' . http_build_query($params);      }      $data = 'city=長沙';      $curlobj = curl_init();         curl_setopt($curlobj, CURLOPT_URL, $url);       curl_setopt($curlobj, CURLOPT_HEADER, 0);      curl_exec($curlobj);
