curl
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
例子1
<?php
$uri = "http://tanteng.duapp.com/test.php";
// 参数数组
$data = array (
‘name‘ => ‘tanteng‘
// ‘password‘ => ‘password‘
);
$ch = curl_init ();
// print_r($ch);
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($_POST[‘name‘])){
if(!empty($_POST[‘name‘])){
echo ‘您好，‘,$_POST[‘name‘].‘！‘;
}
}
?>
例子2
用CURL模拟POST请求抓取邮编与地址
完整代码：
#!/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); // 发送一个常规的Post请求
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‘;
?>
例子3
模拟POST请求 提交数据或上传文件 .
http://www.a.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);
//启用时会发送一个常规的POST请求，类型为：application/x-www-form-urlencoded，就像表单提交的一样。
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 函数介绍
■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
■curl_multi_exec — 运行当前 cURL 句柄的子连接
■curl_multi_getcontent — 如果设置了CURLOPT_RETURNTRANSFER，则返回获取的输出的文本流
■curl_multi_info_read — 获取当前解析的cURL的相关传输信息
■curl_multi_init — 返回一个新cURL批处理句柄
■curl_multi_remove_handle — 移除curl批处理句柄资源中的某个句柄资源
■curl_multi_select — 等待所有cURL批处理中的活动连接
■curl_setopt_array — 为cURL传输会话批量设置选项
