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
<?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';

发送POST请求
<?php
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
<?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
■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
■curl_setopt — 设置一个cURL传输选项
