Handling file uploads
Body handler is also used to handle multi-part file uploads.

If a body handler is on a matching route for the request, any file uploads will be automatically streamed to the uploads directory, which is file-uploads by default.

Each file will be given an automatically generated file name, and the file uploads will be available on the routing context with fileUploads.

Here’s an example:

router.route().handler(BodyHandler.create());

router.post("/some/path/uploads").handler(routingContext -> {

Set<FileUpload> uploads = routingContext.fileUploads();
// Do something with uploads....

});
Each file upload is described by a FileUpload instance, which allows various properties such as the name, file-name and size to be accessed.

請問一下你用的ZXing是哪個版本，具體是用了哪個幾個模塊？？？

電腦端瀏覽器可以拖動大小，手機(jī) pad上也有可能分屏，所以不能直接用屏幕大小

我們公司命名上都是加前綴或者后綴，action: ACT_getList,mutation: MUT_getList。
再詳細(xì)一點的，還需要加上對應(yīng)的分組名稱： action: ACT_MENU_getList，僅供參考吧。

1. 可以嘗試一下動態(tài)設(shè)置MaxHeight
2. 調(diào)試一下UI，看看最大化后window的高度和寬度的值，與系統(tǒng)屏幕的值，哪里不一樣。

這里有參考的鏈接https://stackoverflow.com/que...，但是不能解決問題

一般是iterm2+zsh 你應(yīng)該是沒有安裝字體 https://www.jianshu.com/p/7de...

修改下notebook的配置

from my jupyter_notebook_config.py file:

# c.NotebookApp.mathjax_url = ''
c.NotebookApp.enable_mathjax = True

digraph startgame {
    node [fontname="SimHei"];  // 設(shè)置節(jié)點屬性，這里設(shè)置字體為黑體
    n1[label="TCP Socket" shape=box];
    n2[label="Data" shape=diamond];
    n3[label="h2\nParse Data" shape=ellipse];
    n4[label="h2\nEvents" shape=diamond];
    n5[label="gethy\nUpdate\nBuffers" shape=ellipse];
    n6[label="gethy\nUParse\nBuffers" shape=ellipse];
    n7[label="gethy\nEvents" shape=diamond];
    n8[label="External\nHandlers" shape=box];

    rankdir=TB;    
    {
        rank=same;
        n1 -> n2 [arrowhead="none"];
        n2 -> n3;
        n3 -> n4 [arrowhead="none"];
    }
    {        
        rank=same;
        n8 -> n7[dir="back"];
        n7 -> n6[arrowhead="none"];
        n6 -> n5[dir="back"];
    }    
    n4 -> n5;
}

1. 可以綁定傳入的this，也就是context；
2. 調(diào)用bind返回的函數(shù)可以接收參數(shù)，也就是arguments

IE8 has virtually no ES5 support, but does support Object.defineProperty, Object.getOwnPropertyDescriptor, JSON parsing & Property access on strings.

來源: Can I use

IE8 實現(xiàn)了 Object.defineProperty() 方法，但 只能在 DOM 對象上使用

來源: MDN

直接把.htaccess放到public不行嗎

你 post 的參數(shù)不是json格式啊，postman都給你提示錯誤了......

將后臺回調(diào)的時間轉(zhuǎn)換再渲染。this.form.record.endTime = new Date(endTime * 1000);//時間戳為10位需乘1000，時間戳為13位的話不需乘1000。

使用rxjava吧
線程操作比較方便

簡單寫了個demo
項目地址

這里用JSoup爬數(shù)據(jù)
然后Rxjava返回數(shù)據(jù)流處理結(jié)果的img src的集合的Observable

在實際Activity中同時獲得兩個Observable,使用zip操作符組合,然后在主線程中將圖片添加到list
刷新adapter

使用Glide加載圖片

不要修改你依賴庫的東西（node_modules 這里面的所有文件），這個路徑為了在項目中使用時正確的找到第三方模塊的位置，是 npm 工作時自動加上的，對你項目沒有任何影響。

...你這個代碼真是...差點繞進(jìn)去了

while (FilesList.SelectedItems.Count>0) //原因未知的死循環(huán)
    {
        FilesList.Items.Remove(FilesList.SelectedItem);
    }

while (1>0){}本來就是死循環(huán)

this的綁定取決于調(diào)用的模式，JavaScript 中一共有4種調(diào)用模式：

• 函數(shù)調(diào)用模式
• 構(gòu)造器調(diào)用模式
• apply/call 調(diào)用模式
• 方法調(diào)用模式

function a(){
   console.log(this)
};

a.prototype.testThis = function() {
    console.log("a.prototype == this:"+(a.prototype == this)); // false
    console.log("a == this:"+(a == this)); // false
    console.log("b == this:"+(b == this)); // true
};

a()              // 函數(shù)調(diào)用模式，this綁定到全局對象

var b = new a(); // 構(gòu)造器調(diào)用模式， 通過new 來調(diào)用， this 會被綁定到新對象上，即 b
b.testThis(); //所以 此時 this指向 b 

a.prototype.testThis.call(a);// apply/call 調(diào)用模式， apply 方法接收的第一個參數(shù)就是要綁定給this的值。

a.prototype.testThis();// 方法調(diào)用模式，綁定發(fā)生在調(diào)用的時候，延遲綁定，此時 this指向a.prototype

上面都是從《JavaScript 語言精粹》里面函數(shù)一章可以找到
