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'; ?>
模拟POST请求 提交数据或上传文件 .

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
■curl_version — 获取cURL版本信息
