Mudlet无插件看图功能

abcabc

Mudlet 4.10.1 (Deepin 20.1 Linux)，没有可用插件，只能自己解决，还好很容易实现，困扰好几个月的切换浏览器打开看图的问题，终于解决。

下面贴出代码。

1. function hidepiclabel(current_pic_labelName, evt)
   
2.   if evt == nil or evt.button == "RightButton" then
   
3.     local ln = current_pic_labelName and current_pic_labelName or getProfileName()
   
4.     hideWindow(ln)
   
5.   end
   
6. end
   
7. 
   
8. function showpic(_, filename)
   
9.   
   
10.   if string.ends(filename, ".html") then
    
11.     -- read the contents of the webpage in
    
12.     local f, s, webpage = io.open(filename)
    
13.     if f then webpage = f:read("*a"); io.close(f) end
    
14.     -- delete the file on disk, don't clutter
    
15.     os.remove(filename)
    
16.    
    
17.     -- parse our downloaded file for the player count
    
18.     -- src="./b2evo_captcha_tmp/b2evo_captcha_CBC7910861405F533B8858798683C6B2.jpg"
    
19.     local imgUrl = "http://fullme.pkuxkx.net/".. webpage:match([[src="([^"]+)"]])
    
20.     current_pic_filepath = getMudletHomeDir().."/codepic/"..current_html_labelName..".jpg"
    
21.     downloadFile(current_pic_filepath, imgUrl)
    
22.    
    
23.   else
    
24.     createLabel(current_html_labelName, codepic[current_html_labelName].x, codepic[current_html_labelName].y, codepic[current_html_labelName].w, codepic[current_html_labelName].h, 1)
    
25.     showWindow(current_html_labelName)
    
26.    
    
27.     setBackgroundImage(current_html_labelName, current_pic_filepath)
    
28.    
    
29.     setLabelDoubleClickCallback(current_html_labelName, "downloadpic", codepic[current_html_labelName].html, current_html_labelName)
    
30.    
    
31.     setLabelClickCallback(current_html_labelName, "hidepiclabel", current_html_labelName)
    
32.         
    
33.     cecho("\n双击刷新图片，右键单击隐藏图片！！！")
    
34.   end
    
35.   
    
36. end
    
37. 
    
38. -- 调用入口
    
39. function downloadpic(htmlUrl, labelName)
    
40.   if not io.exists(getMudletHomeDir().."/codepic/") then
    
41.     os.execute("mkdir -p "..getMudletHomeDir().."/codepic/")
    
42.   end
    
43.   local ln = labelName or getProfileName()
    
44.   --debugc("当前labelname.."..ln)
    
45.   codepic[ln].html = htmlUrl
    
46.   current_html_url = htmlUrl
    
47.   current_html_labelName = ln
    
48.   current_html_filepath = getMudletHomeDir().."/codepic/"..ln..".html"
    
49.   --debugc("图片下载路径1"..current_html_filepath)
    
50.   downloadFile(current_html_filepath, htmlUrl)
    
51. end
    
52. 
    
53. 
    
54. function showpicfail(evt, errorFound)
    
55.   cecho("\n下载图片失败，尝试用浏览器打开！")
    
56.   openUrl(current_html_url)
    
57. end
    
58. 
    
59. 
    
60. registerAnonymousEventHandler("sysDownloadDone", "showpic")
    
61. --registerAnonymousEventHandler("sysDownloadError", "showpicfail")

预定义的变量：

1. codepic = {
   
2.   fullme_xkx = {x = 1000, y = 500, w = 900, h = 110, html = ""},
   
3.   xkx = {x = 400, y = 350, w = 1500, h = 110, html = ""}
   
4. }
