php 上传文件到服务器

/客户端代码

function upload()

{                      

 $file = $this->upload->data();

$file_name = $file['file_name'];

$filepath = getcwd().'/assets/android/'.$file_name;

读取文件内容

$handle = fopen($filename, "r");//读取二进制文件时，需要将第二个参数设置成'rb'

$contents = fread($handle, filesize ($filepath));//通过filesize获得文件大小，将整个文件一下子读到一个字符串中

fclose($handle);

删除本地刚上传此文件

unlink($filepath);

//客户端

文件内容转换成base64

$this->data['filecontent']=base64_encode($contents);

SERVER_BASE_URL="http://192.168.1.104:8080/ucenter";

$url_active = SERVER_BASE_URL."/index.php?/api/apns/upload";

$response = $this->curl_post ( $url_active, $this->data );

}

function curl_post($url, $vars) {

    $ch = curl_init();

    curl_setopt($ch,CURLOPT_RETURNTRANSFER, 1);

    curl_setopt($ch, CURLOPT_URL,$url);

    curl_setopt($ch, CURLOPT_POST, 1 );

    curl_setopt($ch, CURLOPT_HEADER, 0 ) ;

    curl_setopt($ch, CURLOPT_POSTFIELDS, $vars);

    $response = curl_exec($ch);

    curl_close($ch);

    if ($response)

    {

    return $response;

    }

    else

    {

    return false;
