把php表达上传文件转化成libcrul 的curl_formadd实现，代码通过，发币！谢谢朋友们帮帮忙吧，总是对应不上！ 有更好的例子也可以！
问题描述：
<?php
$header_prefix = 'file';
$slots = 6;
?>
<html>
<head>
<title>Test upload</title>
</head>
<body>
<?php
if ($_POST){
echo "<h2>Uploaded files:</h2>";
echo "<table border=\"2\" cellpadding=\"2\">";
echo "<tr><td>Name</td><td>Location</td><td>Content type</td><td>MD5</td><td>Size</td><td>Scp Command</td><td>Wget Command</tr>";
for ($i=1;$i<=$slots;$i++){
$key = $header_prefix.$i;
if (array_key_exists($key."_name", $_POST) && array_key_exists($key."_path",$_POST)) {
$tmp_name = $_POST[$key."_path"];
$name = $_POST[$key."_name"];
$content_type = $_POST[$key."_content_type"];
$md5 = $_POST[$key."_md5"];
$size = $_POST[$key."_size"];
$final_path = "/export/share/upload";
if (copy($tmp_name, "$final_path/$name")) {
echo "SUCCESS!";
} else {
echo "FAIL!";
}
$scp_cmd = "scp team@***:/export/share/upload/$name .";
$wget_cmd = "wget http://***/files/upload/$name";
echo "<tr><td>$name</td><td>$final_path</td><td>$content_type</td><td>$md5</td><td>$size</td><td>$scp_cmd</td><td>$wget_cmd</td>";
}
}
echo "</table>";
}else{?>
<h2>Select files to upload</h2>
<form name="upload" method="POST" enctype="multipart/form-data" action="/upload">
<input type="file" name="file1"><br>
<input type="file" name="file2"><br>
<input type="file" name="file3"><br>
<input type="file" name="file4"><br>
<input type="file" name="file5"><br>
<input type="file" name="file6"><br>
<input type="submit" name="submit" value="Upload">
<input type="hidden" name="test" value="value">
</form>
<?php
}
?>
</body>
</html>
把以上的PHP动态提交表单的行为，用libcurl 中 curl_formadd 实现，感谢路过的大神伸出智慧之手！需要使用C++完成上面的实现
答
// form.php
/**
* curl Post文件，php5以下版本可用
*
* @param $action (处理上传文件的url，form表单的action)
* @param $path (文件路径)
**/
function upload_file($action, $path){
$data = array(
// 需要注意的是，在路径前必须带上@，不然只会当做是简单的键值对
'pic' => '@'.realpath($path)
'name' => 'issac'
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $action);
curl_setopt($ch, CURLOPT_POST, true );
curl_setopt($ch, CURLOPT_POSTFIELDS, $data); //该curl_setopt可以向header写键值对
curl_setopt($ch, CURLOPT_HEADER, false); // 不返回头信息
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec($ch);
curl_close($ch);
return $output;
}
// 调用
upload_file('accrpt.php', '/files/img.png');
