php curl 发送get或者post请求

akyou56

　　php可以扮演资料的发送者。

• 　　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($ch, CURLOPT_POST, true); // 啟用POST
curl_setopt($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 = 'http://127.0.0.1/accept.php';
        //This needs to be the full path to the file you want to send.
$file_name_with_full_path = realpath('./sample.jpeg');
        /* 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";
