1、下载uploadify, 我的是v3.2
2、模板页面引入：
<base href='{base_url()}' />
<script type="text/javascript" src="/public/admin/js/jquery.js"></script>
<script type="text/javascript" src="/public/js/ajaxfileupload.js"></script>
<script type="text/javascript" src="/public/js/uploadify/jquery.uploadify.min.js"></script>
<link rel="stylesheet" type="text/css" href="/public/js/uploadify/uploadify.css" />
3、模板页面使用：
<tr>
<td style="text-align:center;padding-top:10px;"><span class="red"> * </span>上传并扫描应用：</td>
<td>
<input id="uploadApk" name="uploaApk" type="file" />
<span id="upload_note">
{if $edit}<font color='red'>已上传应用“{$apply['name']}” </font>{else}<font color='red'>建议应用包100M以内</font>{/if}
</span>
</td> </tr>
4、js code:
<script>
window.apk_uploading_flag = 0;
$(function() {
var seid = '{$seid}' ;
var type = '' ;
var vid = "{$apply['vid']}";
$("#uploadApk").uploadify({
height : 30,
swf : '/public/js/uploadify/uploadify.swf',//Uploadify 自带的flash
uploader : '/admin/ajaxSelfUpload',//ajax提交页面
width : 120,
buttonText : '上传应用',
method : 'post',
debug : false,
fileTypeExts : '*.apk',
sizeLimit : 512000,
fileObjName : 'uploadApk',
progressData : 'speed' ,
formData : { 'session_tmp': '' },
onUploadStart:function(){
window.apk_uploading_flag = 1;
$("#uploadApk").uploadify('settings','formData',{ 'session': seid});
},
onUploadComplete:function(){
window.apk_uploading_flag = 0;
},
onUploadSuccess:function(file,data,response){
var data = JSON.parse(data)
if(data.status){
$("#upload_note font").html('应用上传并扫描成功');
}else{
$("#upload_note font").html(data.info);
}
}
}); </script>
5、controller中代码
1、seid取值
$this->assign('seid', $this->input->cookie($this->config->item('cookie_prefix') . $this->config->item('sess_cookie_name')));
2、上传函数
/**
* 上传应用本身并扫描
*/
public function ajaxSelfUpload() { $strError = '';
$this->load->library("MyUpload");//上传类
$tmpFile = $_FILES['uploadApk'];
$editId = $this->input->get('vid');
$apkSize = $tmpFile['size'];
$apkName = $tmpFile['name'];
//判断文件格式、大小、判断包名是否已经存在
//通过aapt获得apk的所有信息，将上传的apk解压到临时目录
$upload = new MyUpload($tmpFile);
$upload->setFileExt(array('apk'));
$upload->setMaxsize(1024 * 1024 * 500); //reset upload path with category
$uploadApkDir = $this->getSelfUploadDir();
$upload->setUploadPath($uploadApkDir);
if (!$upload->isAllowedTypes()) {
$strError = '上传文件不是有效的apk文件';
} elseif ($upload->isBigerThanMaxSize()) {
$strError = '上传文件最大不能超过 ' . intval($upload->getMaxsize() / 1024) . 'KB';
} //保证上传的生成的文件唯一而不覆盖其他文件
if (empty($strError) and $upload->upload(false, FALSE)) { $uploadApkFilePath = $upload->getUplodedFilePath();
$this->load->library('ParseApkInfo');
$ParseApkInfo = new ParseApkInfo($uploadApkFilePath);
$apkInfoArray = $ParseApkInfo->getApkMoreInfo(); if (!$ParseApkInfo->getErrorMessage() && $apkInfoArray) { $apkInfoArray['icon'] = $ParseApkInfo->createApkIcon('/auto/apply/img/', '/auto/apply/img/');
if (!$ParseApkInfo->getErrorMessage()) {
$apkInfoArray['size'] = $apkSize;
$apkInfoArray['size_mb'] = round($apkSize / 1024 / 1024, 2);
$apkInfoArray['apk'] = ToolsHelper::getFileAccessUrl($uploadApkFilePath);
$apkInfoArray['icon_url'] = ToolsHelper::getFileAccessUrl($apkInfoArray['icon']);
ajaxReturn("OK", true, $apkInfoArray);
}
}
ajaxReturn($ParseApkInfo->getErrorMessage(), false);
} else {
ajaxReturn($strError, false);
}
} /**
* 应用apk包存放目录
* @return string
*/
private function getSelfUploadDir() {
return ToolsHelper::getSelfUploadDir();
}
基本配置完成，但是由于是在管理后台上传文件，所以flash 没有上传session需要手工配置下CI（uploadify配置本身简单，就是再配置后台登录上传的session的时候我花费了很长 时间所以跟大家分享出来）
修改system\libraries下面的Session.php文件：
修改sess_read函数：修改了2处
function sess_read()
{
// Fetch the cookie
//$session = $this->CI->input->cookie($this->sess_cookie_name);
//为了能够在各大浏览器支持falsh上传文件，对140行处进行以下修改 （修改第一处）
if($this->CI->input->post('session_tmp')){
$session = $this->CI->input->post('session_tmp');
}else{
$session = $this->CI->input->cookie($this->sess_cookie_name);
}
//修改结束 // No cookie? Goodbye cruel world!...
if ($session === FALSE)
{
log_message('debug', 'A session cookie was not found.');
return FALSE;
} // HMAC authentication
$len = strlen($session) - 40; if ($len <= 0)
{
log_message('error', 'Session: The session cookie was not signed.');
return FALSE;
} // Check cookie authentication
$hmac = substr($session, $len);
$session = substr($session, 0, $len); // Time-attack-safe comparison
$hmac_check = hash_hmac('sha1', $session, $this->encryption_key);
$diff = 0; for ($i = 0; $i < 40; $i++)
{
$xor = ord($hmac[$i]) ^ ord($hmac_check[$i]);
$diff |= $xor;
} if ($diff !== 0)
{
log_message('error', 'Session: HMAC mismatch. The session cookie data did not match what was expected.');
$this->sess_destroy();
return FALSE;
} // Decrypt the cookie data
if ($this->sess_encrypt_cookie == TRUE)
{
$session = $this->CI->encrypt->decode($session);
} // Unserialize the session array
$session = $this->_unserialize($session); // Is the session data we unserialized an array with the correct format?
if ( ! is_array($session) OR ! isset($session['session_id']) OR ! isset($session['ip_address']) OR ! isset($session['user_agent']) OR ! isset($session['last_activity']))
{
$this->sess_destroy();
return FALSE;
} // Is the session current?
if (($session['last_activity'] + $this->sess_expiration) < $this->now)
{
$this->sess_destroy();
return FALSE;
} // Does the IP Match?
if ($this->sess_match_ip == TRUE AND $session['ip_address'] != $this->CI->input->ip_address())
{
$this->sess_destroy();
return FALSE;
}
//为了能够在各大浏览器支持falsh上传文件，对199行处进行以下修改 （修改第二处）
if (stristr($this->CI->input->user_agent(),'shockwave'))
{
$this->sess_match_useragent = FALSE;
}
//修改结束 // Does the User Agent Match?
if ($this->sess_match_useragent == TRUE AND trim($session['user_agent']) != trim(substr($this->CI->input->user_agent(), 0, 120)))
{
$this->sess_destroy();
return FALSE;
} // Is there a corresponding session in the DB?
if ($this->sess_use_database === TRUE)
{
$this->CI->db->where('session_id', $session['session_id']); if ($this->sess_match_ip == TRUE)
{
$this->CI->db->where('ip_address', $session['ip_address']);
} if ($this->sess_match_useragent == TRUE)
{
$this->CI->db->where('user_agent', $session['user_agent']);
} $query = $this->CI->db->get($this->sess_table_name); // No result? Kill it!
if ($query->num_rows() == 0)
{
$this->sess_destroy();
return FALSE;
} // Is there custom data? If so, add it to the main session array
$row = $query->row();
if (isset($row->user_data) AND $row->user_data != '')
{
$custom_data = $this->_unserialize($row->user_data); if (is_array($custom_data))
{
foreach ($custom_data as $key => $val)
{
$session[$key] = $val;
}
}
}
} // Session is valid!
$this->userdata = $session;
unset($session); return TRUE;
}
疑问：刚开始配置完仍然上传不成功，后来排查原因，什么也没改动，然后不小心试了试就好了……所以如有问题@me
