PHP模拟浏览器上传(数据流形式上传)文件

记录

上传文件的时候,发现new \CURLFile(realpath($file)); 这种形式不可以.原来他是以文件流形式上传

记录一下代码,以后用到好找:

//网址 参数 文件
function upload($url, $p, $file) {
	$param = [
		//此处根据实际文件的上传的 name 填写
		'fileData' => file_get_contents(realpath($file)),
	];
	if (!empty($p)) {
		arrary_merge($p, $param);
	}
	$delimiter = uniqid();
	$data = '';
	$eol = "\r\n";
	$upload = $param['fileData'];
	unset($param['fileData']);
	foreach ($param as $name => $content) {
		$data .= "--" . $delimiter . "\r\n"
			. 'Content-Disposition: form-data; name="' . $name . "\"\r\n\r\n"
			. $content . "\r\n";
	}
	// 拼接文件流  name="fileData"; filename="1.png"' 根据实际的文件 name 和名字填写 或写个变量
	//'Content-Type: image/gif'可改为'Content-Type:application/octet-stream' 由于我是测试的网站必须为 gif 所以就这样吧先
	$data .= "--" . $delimiter . $eol
		. 'Content-Disposition: form-data; name="fileData"; filename="1.png"' . "\r\n"
		. 'Content-Type: image/gif' . "\r\n\r\n";

	$data .= $upload . "\r\n";
	$data .= "--" . $delimiter . "--\r\n";
	$post_data = $data;
	$curl = curl_init($url);
	curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
	curl_setopt($curl, CURLOPT_POST, true);
	curl_setopt($curl, CURLOPT_POSTFIELDS, $post_data);
	curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
	curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
	curl_setopt($curl, CURLOPT_HTTPHEADER, [
		"Content-Type: multipart/form-data; boundary=" . $delimiter,
		"Content-Length: " . strlen($post_data),
	]);
	$response = curl_exec($curl);
	curl_close($curl);
	return $response;
}

大概就是这个意思. 有几处需要根据实际环境来操作.我这里就是记录一下思路而已.
