PHP做接口中用到调用远程url的几种方法
来源:zhoz
上午终于把IF接口设计好了,加密与解密认证通过客户认定。主要通过三个参数来识别验证。
下面将用到向远程服务器提交参数,并获取结果来处理。
先收集几种远程执行URL并取得结果的方法。晚上有时间就完成这个功能。
方法1: 用file_get_contents 以get方式获取内容
- <?php
- $url='http://www.zhoz.com/';
- $html = file_get_contents($url);
- //print_r($http_response_header);
- ec($html);
- printhr();
- printarr($http_response_header);
- printhr();
- ?>
方法2: 用fopen打开url, 以get方式获取内容
我觉得这个方法比较常用。
- <?php
- $fp = fopen($url, 'r');
- printarr(stream_get_meta_data($fp));
- printhr();
- while(!feof($fp)) {
- $result .= fgets($fp, 1024);
- }
- echo "url body: $result";
- printhr();
- fclose($fp);
- ?>
方法3:用file_get_contents函数,以post方式获取url
- <?php
- $data = array ('foo' => 'bar');
- $data = http_build_query($data);
- $opts = array (
- 'http' => array (
- 'method' => 'POST',
- 'header'=> "Content-type: application/x-www-form-urlencodedrn" .
- "Content-Length: " . strlen($data) . "rn",
- 'content' => $data
- ),
- );
- $context = stream_context_create($opts);
- $html = file_get_contents('http://localhost/e/admin/test.html', false, $context);
- echo $html;
- ?>
方法4:用fsockopen函数打开url,以get方式获取完整的数据,包括header和body
- <?php
- function get_url ($url,$cookie=false) {
- $url = parse_url($url);
- $query = $url[path]."?".$url[query];
- ec("Query:".$query);
- $fp = fsockopen( $url[host], $url[port]?$url[port]:80 , $errno, $errstr, 30);
- if (!$fp) {
- return false;
- } else {
- $request = "GET $query HTTP/1.1rn";
- $request .= "Host: $url[host]rn";
- $request .= "Connection: Closern";
- if($cookie) $request.="Cookie: $cookien";
- $request.="rn";
- fwrite($fp,$request);
- while(!@feof($fp)) {
- $result .= @fgets($fp, 1024);
- }
- fclose($fp);
- return $result;
- }
- }
- //获取url的html部分,去掉header
- function GetUrlHTML($url,$cookie=false) {
- $rowdata = get_url($url,$cookie);
- if($rowdata)
- {
- $body= stristr($rowdata,"rnrn");
- $body=substr($body,4,strlen($body));
- return $body;
- }
- return false;
- }
- ?>
方法5:用fsockopen函数打开url,以POST方式获取完整的数据,包括header和body
- <?php
- function HTTP_Post($URL,$data,$cookie, $referrer="") {
- // parsing the given URL
- $URL_Info=parse_url($URL);
- // Building referrer
- if($referrer=="") // if not given use this script as referrer
- $referrer="111";
- // making string from $data
- foreach($data as $key=>$value)
- $values[]="$key=".urlencode($value);
- $data_string=implode("&",$values);
- // Find out which port is needed - if not given use standard (=80)
- if(!isset($URL_Info["port"]))
- $URL_Info["port"]=80;
- // building POST-request:
- $request.="POST ".$URL_Info["path"]." HTTP/1.1n";
- $request.="Host: ".$URL_Info["host"]."n";
- $request.="Referer: $referern";
- $request.="Content-type: application/x-www-form-urlencodedn";
- $request.="Content-length: ".strlen($data_string)."n";
- $request.="Connection: closen";
- $request.="Cookie: $cookien";
- $request.="n";
- $request.=$data_string."n";
- $fp = fsockopen($URL_Info["host"],$URL_Info["port"]);
- fputs($fp, $request);
- while(!feof($fp)) {
- $result .= fgets($fp, 1024);
- }
- fclose($fp);
- return $result;
- }
- printhr();
- ?>
方法6:使用curl库,使用curl库之前,你可能需要查看一下php.ini,查看是否已经打开了curl扩展
- <?php
- $ch = curl_init();
- $timeout = 5;
- curl_setopt ($ch, CURLOPT_URL, 'http://www.zhoz.com/');
- curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
- curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
- $file_contents = curl_exec($ch);
- curl_close($ch);
- echo $file_contents;
- ?>
关于curl库:
curl官方网站http://curl.haxx.se/
curl 是使用URL语法的传送文件工具,支持FTP、FTPS、HTTP HTPPS SCP SFTP TFTP TELNET DICT FILE和LDAP。curl 支持SSL证书、HTTP POST、HTTP PUT 、FTP 上传,k
erberos、基于HTT格式的上传、代理、cookie、用户+口令证明、文件传送恢复、http代理通道和大量其他有用的技巧,最近热门的SNS中也用到这个方法,取得MSN上的好友列表等,应用还是挺多的。只不过需要组件支持,开启方法我的技术圈中有说明:http://o.zhoz.com/
- <?php
- function printarr(array $arr)
- {
- echo "<br> Row field count: ".count($arr)."<br>";
- foreach($arr as $key=>$value)
- {
- echo "$key=$value <br>";
- }
- }
- ?>
