php curl模拟post请求提交数据例子总结
在php中要模拟post请求数据提交我们会使用到curl函数,下面我来给大家举几个curl模拟post请求提交数据例子有需要的朋友可参考参考.
注意:curl函数在php中默认是不被支持的,如果需要使用curl函数我们需在改一改你的php.ini文件的设置,找到php_curl.dll去掉前面的";"就行了.
例1,代码如下:
- <?php
- $uri = "http://tanteng.duapp.com/test.php";
-
- $data = array (
- 'name' => 'tanteng'
-
- );
-
- $ch = curl_init ();
-
- curl_setopt ( $ch, CURLOPT_URL, $uri );
- curl_setopt ( $ch, CURLOPT_POST, 1 );
- curl_setopt ( $ch, CURLOPT_HEADER, 0 );
- curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 );
- curl_setopt ( $ch, CURLOPT_POSTFIELDS, $data );
- $return = curl_exec ( $ch );
- curl_close ( $ch );
-
- print_r($return);
- ?>
接受php页面远程服务器:
- <?php
- if(isset($_POST['name'])){
- if(!emptyempty($_POST['name'])){
- echo '您好,',$_POST['name'].'!';
- }
- }
- ?>
例2,用CURL模拟POST请求抓取邮编与地址,完整代码如下:
- #!/usr/local/php/bin/php
- <?php
- $runtime = new runtime ();
- $runtime->start ();
-
- $cookie_jar = tempnam('/tmp','cookie');
-
- $filename = $argv[1];
- $start_num= $argv[2];
- $end_num = $argv[3];
-
- for($i=$start_num; $i<$end_num; $i++){
- $zip = sprintf('6s',$i);
- $fields_post = array(
- 'postcode' => $zip,
- 'queryKind' => 2,
- 'reqCode' => 'gotoSearch',
- 'search_button.x'=>37,
- 'search_button.y'=>12
- );
-
- $fields_string = http_build_query ( $fields_post, '&' );
- $ch = curl_init();
- curl_setopt($ch, CURLOPT_URL, "URL?reqCode=gotoSearch&queryKind=2&postcode=".$zip);
- curl_setopt($ch, CURLOPT_HEADER, true);
- curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
- curl_setopt($ch, CURLOPT_POST, true);
- curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 120 );
- curl_setopt($ch, CURLOPT_REFERER, $refer );
- curl_setopt($ch, CURLOPT_HTTPHEADER, $headers_login );
- curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_jar );
- curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_jar );
- curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
- curl_setopt($ch, CURLOPT_POST, 1);
- curl_setopt($ch, CURLOPT_POSTFIELDS, $fields_string );
-
- $data = curl_exec($ch);
- preg_match_all('/id="table1">[s]*?<tr>[s]*?<td class="maintext">[sS]*?</td>[s]*?</tr>/', $data, $matches);
- if (!$handle = fopen($filename, 'a+')) {
- echo "不能打开文件 $filename";
- echo "n";
- exit;
- }
-
-
- if (fwrite($handle, $matches[0][1]) === FALSE) {
- echo "不能写入到文件 $filename";
- echo "n";
- exit;
- }
-
- echo "成功地将 $somecontent 写入到文件$filename";
- echo "n";
-
- fclose($handle);
- curl_close($ch);
- }
-
- class runtime
- {
- var $StartTime = 0;
- var $StopTime = 0;
- function get_microtime()
- {
- list($usec,$sec)=explode(' ',microtime());return((float)$usec+(float)$sec);
- }
- function start()
- {
- $this->StartTime=$this->get_microtime();
- }
- function stop(){
- $this->StopTime=$this->get_microtime();
- }
- function spent()
- {
- return ($this->StopTime-$this->StartTime);
- }
- }
- $runtime->stop ();
- $con = 'Processed in'.$runtime->spent().'seconds';
- echo 'Processed in'. $runtime->spent().'seconds';
- ?>
模拟POST请求,提交数据或上传文件,代码如下:
http://www.phpfensi.com/a.php
发送POST请求:
- function execUpload(){
- $file = '/doucment/Readme.txt';
- $ch = curl_init();
- $post_data = array(
- 'loginfield' => 'username',
- 'username' => 'ybb',
- 'password' => '123456',
- 'file' => '@d:usrwwwtranslatedocumentReadme.txt'
- );
- curl_setopt($ch, CURLOPT_HEADER, false);
-
- curl_setopt($ch, CURLOPT_POST, true);
- curl_setopt($ch,CURLOPT_BINARYTRANSFER,true);
- curl_setopt($ch, CURLOPT_POSTFIELDS,$post_data);
- curl_setopt($ch, CURLOPT_URL, 'http://www.b.com/handleUpload.php');
- $info= curl_exec($ch);
- curl_close($ch);
-
- print_r($info);
-
- }
2.http://www.b.com/handleUpload.php
- function handleUpload(){
- print_r($_POST);
- echo '===file upload info:';
- print_r($_FILES);
- }
■cURL 函数
■curl_close — 关闭一个cURL会话
■curl_copy_handle — 复制一个cURL句柄和它的所有选项
■curl_errno — 返回最后一次的错误号
■curl_error — 返回一个保护当前会话最近一次错误的字符串
■curl_exec — 执行一个cURL会话
■curl_getinfo — 获取一个cURL连接资源句柄的信息
■curl_init — 初始化一个cURL会话
■curl_multi_add_handle — 向curl批处理会话中添加单独的curl句柄
■curl_multi_close — 关闭一组cURL句柄
