Firefox扩展自动更新功能 [英] Firefox extension automatic update feature

问题描述

我正在学习 http://www.borngeek.com / firefox / automatic-firefox-extension-updates / ，使我的FF扩展可以自动更新到用户，但我坚持最后一部分托管更新清单，因为我使用Tomcat服务，我没有想法如何设置.htaccess（.h​​taccess文件是否与配置服务器方面的WEB-INF目录类似）

到目前为止，我已经做了，

创建密钥对：公钥和私钥

计算sha256：b3290c69a1 ...

创建update.rdf

 
 <？xml version =1.0？> 
  xmlns =http：// www。 mozilla.org/2004/em-rdf#\"> 
 
< r：说明about =urn：mozilla：extension：[e-mail]> 
<更新> 
< r：Seq> 
< r：li> 
< r：说明> 
< version> 1.0.1< / version> 
< targetApplication> 
< r：说明> 
< id> {ec8030f7-c20a-464f-9b0e-13a3a9e97384}< / id> 
< minVersion> 3.5< / minVersion> 
< maxVersion> 5.0。*< / maxVersion> 
< updateLink> http：// localhost：8080 / myextension / pluginupdate / myextension.xpi< / updateLink> 
< updateHash> 
 sha256：b3290c69a1 ... 
< / updateHash> 
< / r：说明> 
< / targetApplication> 
< / r：说明> 
< / r：li> 
< / r：Seq> 
< / updates> 
< / r：说明> 
 
< / r：RDF> 
 

使用Key签署update.rdf

放置单独的update.rdf和myextension pluginupdate目录下的.xpi，其中pluginupdate与WEB-INF在同一级别。

我的install.rdf

 
<？xml version =1.0？> 
 
  
 xmlns：em = http://www.mozilla.org/2004/em-rdf#\">

当我重启FF浏览器时，没有任何反应。
当我使用带有选项-console的命令行启动FF Browser时b
$ b

 
 *** LOG addons.xpi：startup 
 *** LOG addons.xpi：checkForChanges 
 *** LOG addons.xpi：找不到更改
 *** LOG addons.xpi：打开数据库
 

那么，如何托管和配置Tomcat来托管更新清单呢？谢谢

更新

嗨弗拉基米尔，

在web.xml的MIME类型中定义后，还有一些与-console选项一起提供的信息。

并重新安装它，日志是

 
 *** LOG addons.xpi：启动
 *** LOG插件。 xpi：checkForChanges 
 *** LOG addons.xpi：找不到更改
 *** addons.xpi：打开数据库
 *** LOG addons.repository：请求https：//服务.addons.mozilla.org / en-GB / firefox / api / 1.5 / search / guid：myextension％40mozilla.myextension.org？src = firefox&appOS = Linux&appVersion = 5.0&tMain = 23&tFirstPaint = 1641&tSessionRestored = 1042

Frome行

我们可以看到Update Manager（？）正在通过https://services.addons.mozilla.org/en-GB/firefox/api/1.5/search/guid:myextension%40mozilla.myextension.org?src向存储库发出请求另外，在启动后

pre>
*** LOG addons.xpi：在app-profile
中找到[e-mail]的更新清单LOG addons.xpi：处理myextension @ mozilla的安装.myextension.org in app-profile

这意味着找到了更新。但是我没有看到浏览器上的通知，告诉我有一个新版本的myextension，更新？。


我错过了什么？

解决方案

.htaccess文件的要点是确保服务器知道MIME类型。看来你可以通过改变conf / web.xml文件来做到这一点：

 < mime-mapping> 
< extension> xpi< / extension> 
< mime-type> application / x-xpinstall< / mime-type> 
< / mime-mapping> 
< mime-mapping> 
< extension> rdf< / extension> 
< mime-type> application / rdf + xml< / mime-type> 
< / mime-mapping> 
  

我查看了update.rdf和install.rdf文件，但没有看到任何明显的问题 - 它应该工作。您可能想要转到 about：config ，然后切换 extensions.logging.enabled 首选项，但这样可以确保（Ctrl-Shift-J打开或在命令行中使用 -jsconsole ）。

I am following the tutorial at http://www.borngeek.com/firefox/automatic-firefox-extension-updates/ to make my FF extension can be updated automatically to users, but I stuck at the last part "Hosting an Update Manifest" as I am using Tomcat serve and I have no ideas how to set up the .htaccess (Is the .htaccess file similar with WEB-INF directory in terms of configure server?)

What I have done so far,

Create a key pair: Public-Key and Private-Key

Calculate sha256: b3290c69a1...

Create update.rdf

<?xml version="1.0"?>
<r:RDF xmlns:r="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
        xmlns="http://www.mozilla.org/2004/em-rdf#">

        </targetApplication>
    </r:Description>
    </r:li>
    </r:Seq>
    </updates>
</r:Description>

</r:RDF>

Sign update.rdf using Key

Place singed update.rdf and myextension.xpi under pluginupdate directory, where pluginupdate is on the same level with WEB-INF.

My install.rdf

When i restart FF Browser, nothing happens. When I start FF Browser using command line with option -console

*** LOG addons.xpi: startup
*** LOG addons.xpi: checkForChanges
*** LOG addons.xpi: No changes found
*** LOG addons.xpi: Opening database

So, how can I host and configure Tomcat to host the update manifest? Thanks

Update

Hi Wladimir,

After define in the MIME type in the web.xml, there are some more information given with the -console option.

I removed the extension and re-installed it, the logs are

*** LOG addons.xpi: startup
*** LOG addons.xpi: checkForChanges
*** LOG addons.xpi: No changes found
*** LOG addons.xpi: Opening database
*** LOG addons.repository: Requesting https://services.addons.mozilla.org/en-GB/firefox/api/1.5/search/guid:myextension%40mozilla.myextension.org?src=firefox&appOS=Linux&appVersion=5.0&tMain=23&tFirstPaint=1641&tSessionRestored=1042
*** LOG addons.xpi: Starting install of file:///home/me/browserplugindev/firefox/test/myextension.xpi
*** LOG addons.xpi: Addon [e-mail] will be installed as a packed xpi
*** LOG addons.xpi: Install of file:///home/me/browserplugindev/firefox/test/myextension.xpi completed.
NOTE: child process received `Goodbye', closing down
*** LOG addons.xpi: shutdown
*** LOG addons.xpi: startup
*** LOG addons.xpi: checkForChanges
*** LOG addons.xpi: Found updated manifest for [e-mail] in app-profile
*** LOG addons.xpi: Processing install of [e-mail] in app-profile
*** LOG addons.xpi: Opening database
*** LOG addons.xpi: New add-on [e-mail] installed in app-profile
*** LOG addons.xpi: Updating database with changes to installed add-ons
*** LOG addons.xpi: Updating add-on states
*** LOG addons.xpi: Writing add-ons list

Frome line

LOG addons.repository: Requesting https://services.addons.mozilla.org/en-GB/firefox/api/1.5/search/guid:myextension%40mozilla.myextension.org?src=firefox&appOS=Linux&appVersion=5.0&tMain=23&tFirstPaint=1641&tSessionRestored=1042

we can see that Update Manager (?) is making request to repository at https://services.addons.mozilla.org/en-GB/firefox/api/1.5/search/guid:myextension%40mozilla.myextension.org?src=firefox&appOS=Linux&appVersion=5.0&tMain=23&tFirstPaint=1641&tSessionRestored=1042

Also, after the startup

*** LOG addons.xpi: Found updated manifest for [e-mail] in app-profile
*** LOG addons.xpi: Processing install of [e-mail] in app-profile

So does it mean that the update is found. But I did not see the notification on the Browser that tell me something like "there is a new version of myextension, update?".

Did i miss anything?

解决方案

The point of the .htaccess file is simply ensuring that the server knows the MIME types. It seems that you can do that for Tomcat by changing conf/web.xml file:

<mime-mapping>
  <extension>xpi</extension>
  <mime-type>application/x-xpinstall</mime-type>
</mime-mapping>
<mime-mapping>
  <extension>rdf</extension>
  <mime-type>application/rdf+xml</mime-type>
</mime-mapping>

I looked through your update.rdf and install.rdf files and I don't see any obvious issues - it should work. You might want to go to about:config and switch on extensions.logging.enabled preference however, this will make sure that additional information is sent to the Error Console (press Ctrl-Shift-J to open or use -jsconsole on the command line).
