3 句代码调用 GitHub API，以及各种表格组件用法展示

科技 09-01 来源： aardio

编程调用 GitHub API 搜索开源项目示例：

import web.rest.github;
var http = web.rest.github(); 
var result = http.api().search.repositories.get(
  sort = "stars";order = "desc";q = "aardio NOT xra stars:>50";
)

很简单吧，只需要 3 句 aardio 代码。
实际上 web.rest.github 的关键源代码也只有 2 句。

下面我们再添加几句代码，将返回结果输出到控制台：

import web.rest.github;
var http = web.rest.github(); 
var result = http.api().search.repositories.get(
  sort = "stars";order = "desc";q = "aardio NOT xra stars:>50";
) 

//在控制台显示
import console; 
console.dumpJson(result); 
console.pause(true);

下面我们再改进一下，用 aardio 编写一个简单的窗口程序显示数据：

源代码：

import win.ui;
/*DSG{{*/
var winform = win.form(text="调用 GitHub API";right=873;bottom=603)
winform.add(
button={cls="button";text="点这里搜索 aardio 开源项目";left=562;top=554;right=855;bottom=596;color=14120960;db=1;dr=1;font=LOGFONT(h=-14);z=2};
richedit={cls="richedit";left=6;top=6;right=868;bottom=545;autohscroll=false;db=1;dl=1;dr=1;dt=1;edge=1;link=1;multiline=1;vscroll=1;z=1}
)
/*}}*/

winform.button.oncommand = function(id,event){
  winform.button.disabledText = {"✶";"✸";"✹";"✺";"✹";"✷"}
  
  thread.invoke( 
    function(winform){
  
      import web.rest.github;
      
      var http = web.rest.github()
      var github = http.api();
      
      var result = github.search.repositories.get(
        sort = "stars";
        order = "desc";
        q = "aardio NOT xra stars:>50";
      )
      
      var items = result.items;
      
      for i,v in table.eachIndex(items){
        winform.richedit.print(v.html_url);
        winform.richedit.print(v.description);
        winform.richedit.print();
      }
      
      winform.button.disabledText = null;
    },winform
  )
}

winform.richedit.onHyperlink =function(message,href){

  if( message = 0x202/*_WM_LBUTTONUP*/ ) {
    import process;
    process.openUrl(href);
  }
}

winform.show();
win.loopMessage();

下面我们再改进一下，调用表格控件 win.ui.grid 显示数据，源码如下：

import win.ui;
/*DSG{{*/
var winform = win.form(text="简单数据视图";right=1031;bottom=712)
winform.add(
listview={cls="listview";left=24;top=27;right=996;bottom=679;edge=1;z=1}
)
/*}}*/

import win.ui.grid;
var grid = win.ui.grid(winform.listview);
grid.setColumns({"名称";"网址";"描述"});

import web.rest.github;
var http = web.rest.github(); 
var dataTable = http.api().search.repositories.get(
  sort = "stars";order = "desc";q = "aardio NOT xra stars:>50";
).items;

//设置要显示的数据列
dataTable.fields = {"name","html_url","description"};

//直接让 listview 控件显示数据库的查询结果
grid.setTable(dataTable)

winform.show() 
win.loopMessage();

下面再改为 aardio 调用 JavaScript ( React，antd ) 表格组件显示数据：

import win.ui;
/*DSG{{*/
var winform = win.form(text="搜索开源项目";right=1111;bottom=709)
winform.add()
/*}}*/

import web.view;
var wb = web.view(winform);

wb.export(
  getData = function(){
    import web.rest.github;

    var http = web.rest.github()
    var github = http.api();
    
    var result = github.search.repositories.get(
      sort = "stars";
      order = "desc";
      q = "aardio NOT xra stars:>50";
    )
    
    return result.items;
  };
)

wb.html = /**


  
  
  
  
  
   
  
  

  




 
**/

winform.show(3/*_SW_MAXIMIZE*/);
win.loopMessage();

下面我们再改用 aardio 调用操作系统自带的 .NET 表格控件显示数据：

import win.ui;
/*DSG{{*/
var winform = win.form(text="嵌入 .Net 控件";right=860;bottom=519)
winform.add(
custom={cls="custom";left=25;top=25;right=840;bottom=497;db=1;dl=1;dr=1;dt=1;z=1}
)
/*}}*/

import System.Type;
import System.Data;
import System.Windows.Forms;
var Forms = System.Windows.Forms;

//嵌入 .Net 表格控件
var dataGridView = Forms.CreateEmbed("DataGridView",winform.custom); 
dataGridView.ColumnHeadersHeightSizeMode = 2; //避免在高分屏下错乱 
dataGridView.AutoSizeRowsMode  = 11/*DisplayedCells*/ //修正部分高分屏下不显示复选框
  
//添加数据列
var dataTable = System.Data.DataTable("DT"); 
dataTable.Columns.Add("名称");
dataTable.Columns.Add("网址");
dataTable.Columns.Add("描述");

//绑定数据源到视图
var dataView = System.Data.DataView(dataTable);
dataGridView.DataSource = dataView;
dataGridView.EditMode = 2; 

//描述列改为自适应宽度
dataGridView.Columns[3].AutoSizeMode = Forms.DataGridViewAutoSizeColumnMode.AllCells;
  
//先移除自动生成的列
dataGridView.Columns.Remove("网址"); 

//添加一个列用于显示超链接
var links = Forms.DataGridViewLinkColumn();
links.DataPropertyName = "FlightLink";
links.ActiveLinkColor = 0xFF00FFFF;
links.LinkBehavior = Forms.LinkBehavior.SystemDefault;
links.LinkColor = 0xFF0000FF;
links.TrackVisitedState = true;
links.VisitedLinkColor = 0xFFFFFF00;
links.Width = 250;
links.DataPropertyName  = "网址";
links.HeaderText = "网址";
links.DisplayIndex = 1;
dataGridView.Columns.Add(links);  

//响应.NET 控件点击表格列事件
dataGridView.CellContentClick = function(sender,e){
  //如果是第 2 列
  if (e.ColumnIndex == 2){
    //取出网址
    var url = dataGridView.Rows[e.RowIndex+1].Cells[e.ColumnIndex+1].Value;
    
    //打开网址
    process.openUrl(url);
  }
}
import process;

import web.rest.github;
var http = web.rest.github()
var github = http.api();

//调用 GitHub API 
var result = github.search.repositories.get(
  sort = "stars";
  order = "desc";
  q = "aardio NOT xra stars:>50";
)

//获取搜索到的开源项目列表
var items = result.items;
for i,v in table.eachIndex(items){
  //添加到表格中
  var row = dataTable.NewRow(); 
  row.ItemArray = {v.name,v.html_url, v.description}
  dataTable.Rows.Add(row);   
}

winform.show();
win.loopMessage();
