老哥，我不是要抬杠哈，比如我輸入了一串英文，獲取字符集結(jié)果為ASCII,然后通過iconv轉(zhuǎn)成utf-8了，后面應該返回utf-8才對。為什么還是返回的ASCII呢?我是比較疑惑的這一點。

$sql = "select count(*) as userNum from ajax_test1 where userName='$uName'";

$result = mysqli_query($con, $sql);
$res = mysqli_fetch_array($result);
//print_r($res);
echo $res['userNum'];

帶變量，將流程經(jīng)過的節(jié)點寫在變量中？
或者直接在數(shù)據(jù)庫中標記流程經(jīng)過的每一個節(jié)點，到達節(jié)點的時候根據(jù)流程id去判斷就可以了。

Authorization 了解一下

我在首頁的組件中打印了

會重復打印

可以在server_name下面這行這個試試

server {
  listen 443;
  # server_name *.ht920.com ht920.com;
  server_name www.ht920.com;
  server_name_in_redirect off;
  ssl on;
  ssl_certificate   cert/1523974750873.pem;
  ssl_certificate_key  cert/1523974750873.key;
  ssl_session_timeout 5m;
  ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
  ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
  ssl_prefer_server_ciphers on;
  location / {
    index index.html index.htm index.php;
    proxy_redirect off;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass https://localhost:8443;
  }
  access_log logs/ht920.com_access.log;
}

應該是你的解析json數(shù)據(jù)出錯導致的

這里的this指向的是fn這個構(gòu)造函數(shù)

進入webapps文件夾下面的ROOT目錄，看一下有沒有index.jsp和其他文件，用localhost:8082就可以直接訪問到index.jsp

因為源碼那里，作者使用的defineproperty(),只監(jiān)控了外部data傳進來的list,而沒有監(jiān)控list里面的每一個下標對象

1. 重新安裝依賴的那個不是錯誤，是一個warn（警告），提示你的系統(tǒng)是windows不支持可選的模塊fsevent，這并不是錯誤；
2. 執(zhí)行run dev的時候，提示資源優(yōu)化失敗，你可以刪除node_module，重新安裝一下，在天朝，建議你使用cnpm來（npm的淘寶鏡像）安裝，安裝的更快，更容易安裝成功
3. 在做2之前先把.gitignore文件加進去，里面寫一行 node_module 然后保存，commit進倉庫，然后在重新安裝node_module

再不行，再來貼圖問吧

請問樓主有沒有最后解決調(diào)這個問題？

不會，不太明白你的意思

雖然不知道你為什么要下載那么古老的 2.0.5 的版本，但是 composer 官網(wǎng)上的 yiisoft/yii2-app-advanced 包并沒 2.0.5 版本。

現(xiàn)在 yiisoft/yii2-app-advanced 的最新版本是 2.0.14，可以使用如下命令進行下載：

composer create-project yiisoft/yii2-app-advanced advanced 2.0.14

實際上，到目前為止，yii2框架核心的版本已經(jīng)是 2.0.15.1，安裝時composer 會自動將其升級為最新版本。

異常分 3 種情況:

1. 協(xié)調(diào)者不宕機，參與者宕機；
2. 協(xié)調(diào)者宕機，參與者不宕機；
3. 協(xié)調(diào)者宕機，參與者也宕機；

對于（1），當在事務(wù)進行過程中，有參與者宕機時，他重啟以后，可以通過詢問其他參與者或者協(xié)調(diào)者，從而知道這個事務(wù)到底提交了沒有。

對于（2），協(xié)調(diào)者宕機后，可以起新的協(xié)調(diào)者，然后查詢所有參與者的狀態(tài)是否有 commit 的，如果有，則繼續(xù) commit，如果都沒有，則 abort。

對于（3），是唯一 2PC 不能解決的：當協(xié)調(diào)者在發(fā)出 commit 消息后宕機了，而唯一收到這條命令的一個參與者也宕機了，這個時候這個事務(wù)就處于一個未知的狀態(tài)，沒有人知道這個事務(wù)到底是提交了還是未提交，從而需要數(shù)據(jù)庫管理員的介入，防止數(shù)據(jù)庫進入一個不一致的狀態(tài)。當然，如果有一個前提是：所有節(jié)點或者網(wǎng)絡(luò)的異常最終都會恢復，那么這個問題就不存在了，協(xié)調(diào)者和參與者最終會重啟，其他節(jié)點也最終也會收到commit T的信息。

要補充具體環(huán)境：

PC端的瀏覽器、版本
移動端是否是微信自帶瀏覽器、瀏覽器、版本

而且你也沒說具體怎么不行了，怎么講。

1. 圖片上傳前壓縮可以借助Cavas，然后再轉(zhuǎn)成Base64存儲在你Editor中。 具體方法可以參考 《前端圖片壓縮上傳(純js的質(zhì)量壓縮，非長寬壓縮)》 中的 canvasDataURL方法
2. 關(guān)于Emoji亂碼問題，請參考 《推送emoji表情亂碼的解決方法》
3. 視頻類的我沒有用過，不過問題不大，原理都是將視頻地址寫到是個視頻播放器中，然后貼到Editor中。

devServer 和 熱更新沒關(guān)系哦，建議你試試重新 run dev
