PHP上传URL地址网络文件到服务器 如何将一个URL地址的网络资源文件上传到服务器？首先考虑的方法是将文件下载到本地，然后进行上传操作，那有没有一个更方便的方法，将一个网络文件直接上传到服务器呢？是不是可以通过文件流的方式上传呢？我这里使用的是 Guzzle 三方库，将一张百度上的图片上传到其他服务器。use GuzzleHttp\Client; try { $file = fopen('https://t8.baidu.com/it/u=1484500186,1503043093&fm=79&app=86&size=h300&n=0&g=4n&f=jpeg', 'r'); $multipart = [ [ 'name' => 'file', 'contents' => $file ] ]; $client = new Client(['verify' => false]); $response = $client->request('POST', 'https://xx.com/upload', [ 'multipart' => $multipart ]); if ($response->getStatusCode() === 200) { $content = $response->getBody()->getContents(); $result = json_decode($content, true); } } catch (\Exception $exception) { echo $exception->getMessage(); } return $result;

PHP模拟浏览器上传文件(数据流形式上传) 用PHP上传文件基本都是临时存储，之后上传，怎么用PHP模拟浏览器以数据流形式上传文件思路及代码如下：//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; }请根据实际情况进行实际调用
