CI(2.2) 配置 jquery的上传插件Uploadify(v3.2) 上传文件
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($strError, false); } } /** * 应用apk包存放目录 * @return string */ private function getSelfUploadDir() { return ToolsHelper::getSelfUploadDir(); }
基本配置完成,但是由于是在管理后台上传文件,所以flash 没有上传session需要手工配置下CI(uploadify配置本身简单,就是再配置后台登录上传的session的时候我花费了很长 时间所以跟大家分享出来)
修改system\libraries下面的Session.php文件:
修改sess_read函数:修改了2处
1 function sess_read() 2 { 3 // Fetch the cookie 4 //$session = $this->CI->input->cookie($this->sess_cookie_name); 5 //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) 6 if($this->CI->input->post(‘session_tmp‘)){ 7 $session = $this->CI->input->post(‘session_tmp‘); 8 }else{ 9 $session = $this->CI->input->cookie($this->sess_cookie_name); 10 } 11 //修改结束 12 13 // No cookie? Goodbye cruel world!... 14 if ($session === FALSE) 15 { 16 log_message(‘debug‘, ‘A session cookie was not found.‘); 17 return FALSE; 18 } 19 20 // HMAC authentication 21 $len = strlen($session) - 40; 22 23 if ($len <= 0) 24 { 25 log_message(‘error‘, ‘Session: The session cookie was not signed.‘); 26 return FALSE; 27 } 28 29 // Check cookie authentication 30 $hmac = substr($session, $len); 31 $session = substr($session, 0, $len); 32 33 // Time-attack-safe comparison 34 $hmac_check = hash_hmac(‘sha1‘, $session, $this->encryption_key); 35 $diff = 0; 36 37 for ($i = 0; $i < 40; $i++) 38 { 39 $xor = ord($hmac[$i]) ^ ord($hmac_check[$i]); 40 $diff |= $xor; 41 } 42 43 if ($diff !== 0) 44 { 45 log_message(‘error‘, ‘Session: HMAC mismatch. The session cookie data did not match what was expected.‘); 46 $this->sess_destroy(); 47 return FALSE; 48 } 49 50 // Decrypt the cookie data 51 if ($this->sess_encrypt_cookie == TRUE) 52 { 53 $session = $this->CI->encrypt->decode($session); 54 } 55 56 // Unserialize the session array 57 $session = $this->_unserialize($session); 58 59 // Is the session data we unserialized an array with the correct format? 60 if ( ! is_array($session) OR ! isset($session[‘session_id‘]) OR ! isset($session[‘ip_address‘]) OR ! isset($session[‘user_agent‘]) OR ! isset($session[‘last_activity‘])) 61 { 62 $this->sess_destroy(); 63 return FALSE; 64 } 65 66 // Is the session current? 67 if (($session[‘last_activity‘] + $this->sess_expiration) < $this->now) 68 { 69 $this->sess_destroy(); 70 return FALSE; 71 } 72 73 // Does the IP Match? 74 if ($this->sess_match_ip == TRUE AND $session[‘ip_address‘] != $this->CI->input->ip_address()) 75 { 76 $this->sess_destroy(); 77 return FALSE; 78 } 79 //为了能够在各大浏览器支持falsh上传文件,对199行处进行以下修改 (修改第二处) 80 if (stristr($this->CI->input->user_agent(),‘shockwave‘)) 81 { 82 $this->sess_match_useragent = FALSE; 83 } 84 //修改结束 85 86 // Does the User Agent Match? 87 if ($this->sess_match_useragent == TRUE AND trim($session[‘user_agent‘]) != trim(substr($this->CI->input->user_agent(), 0, 120))) 88 { 89 $this->sess_destroy(); 90 return FALSE; 91 } 92 93 // Is there a corresponding session in the DB? 94 if ($this->sess_use_database === TRUE) 95 { 96 $this->CI->db->where(‘session_id‘, $session[‘session_id‘]); 97 98 if ($this->sess_match_ip == TRUE) 99 { 100 $this->CI->db->where(‘ip_address‘, $session[‘ip_address‘]); 101 } 102 103 if ($this->sess_match_useragent == TRUE) 104 { 105 $this->CI->db->where(‘user_agent‘, $session[‘user_agent‘]); 106 } 107 108 $query = $this->CI->db->get($this->sess_table_name); 109 110 // No result? Kill it! 111 if ($query->num_rows() == 0) 112 { 113 $this->sess_destroy(); 114 return FALSE; 115 } 116 117 // Is there custom data? If so, add it to the main session array 118 $row = $query->row(); 119 if (isset($row->user_data) AND $row->user_data != ‘‘) 120 { 121 $custom_data = $this->_unserialize($row->user_data); 122 123 if (is_array($custom_data)) 124 { 125 foreach ($custom_data as $key => $val) 126 { 127 $session[$key] = $val; 128 } 129 } 130 } 131 } 132 133 // Session is valid! 134 $this->userdata = $session; 135 unset($session); 136 137 return TRUE; 138 }
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
