php越来越前端化,大型系统中的php经常是调用后端服务的接口,这里分享一个函数。希望对大家有用。
/** * [http 调用接口函数] * @Date 2016-07-11 * @Author GeorgeHao * @param string $url [接口地址] * @param array $params [数组] * @param string $method [GETPOSTDELETEPUT] * @param array $header [HTTP头信息] * @param integer $timeout [超时时间] * @return [type] [接口返回数据] */ function http($url, $params, $method = 'GET', $header = array(), $timeout = 5) { // POST 提交方式的传入 $set_params 必须是字符串形式 $opts = array( CURLOPT_TIMEOUT => $timeout, CURLOPT_RETURNTRANSFER => 1, CURLOPT_SSL_VERIFYPEER => false, CURLOPT_SSL_VERIFYHOST => false, CURLOPT_HTTPHEADER => $header ); /* 根据请求类型设置特定参数 */ switch (strtoupper($method)) { case 'GET': $opts[CURLOPT_URL] = $url . '?' . http_build_query($params); break; case 'POST': $params = http_build_query($params); $opts[CURLOPT_URL] = $url; $opts[CURLOPT_POST] = 1; $opts[CURLOPT_POSTFIELDS] = $params; break; case 'DELETE': $opts[CURLOPT_URL] = $url; $opts[CURLOPT_HTTPHEADER] = array("X-HTTP-Method-Override: DELETE"); $opts[CURLOPT_CUSTOMREQUEST] = 'DELETE'; $opts[CURLOPT_POSTFIELDS] = $params; break; case 'PUT': $opts[CURLOPT_URL] = $url; $opts[CURLOPT_POST] = 0; $opts[CURLOPT_CUSTOMREQUEST] = 'PUT'; $opts[CURLOPT_POSTFIELDS] = $params; break; default: throw new Exception('不支持的请求方式!'); } /* 初始化并执行curl请求 */ $ch = curl_init(); curl_setopt_array($ch, $opts); $data = curl_exec($ch); $error = curl_error($ch); return $data; }
这个函数缺少验证调用权限,改天有空了完善。
