php可以扮演资料的发送者。

1. 简单的get
   

$ch = curl_init();curl_setopt($ch, CURLOPT_URL, "http://SomeDomain/SamplePath?SomeVar=test");curl_exec($ch);curl_close($ch);

2. 简单的post

$ch = curl_init();curl_setopt($ch, CURLOPT_URL, "http://SomeDomain/SamplePath");curl_setopt($ch, CURLOPT_POST, true); // 啟用POSTcurl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query( array( "a"=>"123", "b"=>"321") )); curl_exec($ch); curl_close($ch);

3. 高级的post，可设置多个参数

$toURL = "http://SomeDomain/SamplePath?SomeVar=XX";$post = array(  "a"=>"123",  "b"=>"321",);$ch = curl_init();$options = array(  CURLOPT_URL=>$toURL,  CURLOPT_HEADER=>0,  CURLOPT_VERBOSE=>0,  CURLOPT_RETURNTRANSFER=>true,  CURLOPT_USERAGENT=>"Mozilla/4.0 (compatible;)",  CURLOPT_POST=>true,  CURLOPT_POSTFIELDS=>http_build_query($post),);curl_setopt_array($ch, $options);// CURLOPT_RETURNTRANSFER=true 会返回服务器响应代码,// false 时只返回成功与否；$result = curl_exec($ch); curl_close($ch);echo $result;

4. post 发送文件

发送端代码：

$target_url = 'https://cache.yisu.com/upload/information/20200310/52/110483.jpg');        /* curl will accept an array here too.         * Many examples I found showed a url-encoded string instead.         * Take note that the 'key' in the array will be the key that shows up in the         * $_FILES array of the accept script. and the at sign '@' is required before the         * file name.         */        $post = array('extra_info' => '123456','file_contents'=>'@'.$file_name_with_full_path);                 $ch = curl_init();        curl_setopt($ch, CURLOPT_URL,$target_url);        curl_setopt($ch, CURLOPT_POST,1);        curl_setopt($ch, CURLOPT_POSTFIELDS, $post);        curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);        $result=curl_exec ($ch);        curl_close ($ch);        echo $result;      

接收端代码：

$uploaddir = realpath('./') . '/';$uploadfile = $uploaddir . basename($_FILES['file_contents']['name']);echo '
';        if (move_uploaded_file($_FILES['file_contents']['tmp_name'], $uploadfile)) {            echo "File is valid, and was successfully uploaded.\n";        } else {            echo "Possible file upload attack!\n";        }        echo 'Here is some more debugging info:';        print_r($_FILES);        echo "\n
\n";        print_r($_POST);print "\n";
