编写一个自定义的协议处理程序，可移植到在Firefox上运行的Firefox，Chrome和IE [英] Writing a custom protocol handler portable on Firefox, Chrome and IE running on Window

问题描述

我正在编写一个协议处理程序来启动一个Java应用程序，调用一个像java -jar myApp'％1'这样的命令。目前我已经实现了它的Chrome浏览器，它看起来工作正确。不幸的是我没有相同的行为Firefox和IE（怪异的？！X-D）

在这里我的实现。

该协议名为dgh。
在第一次安装过程中，我的应用程序在Windows注册表中设置了下列键值：

$ p code $ Windows注册表编辑器版本5.00

[HKEY_CLASSES_ROOT\dgh]
@ =URL：DgHome Protocol
URL Procol=

[HKEY_CLASSES_ROOT\dgh\DefaultIcon]
@ =C：/DGHOME/IPlusConf.exe,1

[HKEY_CLASSES_ROOT \dgh\shell]

[HKEY_CLASSES_ROOT\dgh\ shell \open]

[HKEY_CLASSES_ROOT\dgh\shell\open\command]
@ =java -jar C：/DGHOME/Pch/lib/pch.teleconsulto .jar \％1 \

在Firefox上，我必须在 about：config 中添加一些配置。在Firefox上的MDN之后，我设置了以下内容：

  network.protocol-handler.expose.dgh; true 
 network.protocol-handler.external.dgh; true 
 network.protocol-handler.warn-external.dgh; false 
  

通过这种方式，firefox至少会询问我是否需要启动应用程序并请求我选择其中之一：我不希望这样，我会打电话给我设置的命令，并建议第一次用户有关：

IE浏览器没有任何反应，它说不能通过我的链接打开网页引用。

这里是我用作测试的一组链接

 < a href =dgh：// call / open？id ='kit1.teleconsulto'>打开调用kit1.teleconsulto< / a> 
< a href =dgh：// teleconsult / start？id ='kit1.teleconsulto'> 
打开teleconsult to kit1.teleconsulto< / a> 
< a href =dgh：// call / close>关闭通话< / a> 
< a href =dgh：// call / end>关闭客户端< / a> 
< a href =dgh：// stethoscope / start> On Phonendo< / a>

解决方案

你遇到的问题是你直接在协议处理程序中调用jar。您需要使用-jar参数调用java.exe
$ b $ p您的注册表项应该像这样

<$ p $ Windows注册表编辑器版本5.00

[HKEY_CLASSES_ROOT\digitalmgi]
@ =URL：digitalmgi协议
URL协议=

[HKEY_CLASSES_ROOT\digitalmgi\DefaultIcon]
@ =C：\\myCoolIcon.ico

[HKEY_CLASSES_ROOT\digitalmgi\Shell ]

[HKEY_CLASSES_ROOT\digitalmgi\Shell\Open】

[HKEY_CLASSES_ROOT\digitalmgi\Shell\Open\Command]
@ = \C：\\ Program Files \\Java\\jre7\\\\\\\\\\\-jar \C：\\\\\\\\\\\\\\\\ \\\myJar.jar\\％1 \

I am writing a protocol handler to launch a java application, calling a command like java -jar myApp '%1'. Currently I have implemented it for Chrome and it looks work correcly. Unfortunately I don't have the same behavior for Firefox and IE (weird uh?! X-D )

Here my implementation.

The protocol is named dgh. During the first installation my application set the following keys in windows registry

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\dgh]
@="URL:DgHome  Protocol"
"URL Procol"=""

[HKEY_CLASSES_ROOT\dgh\DefaultIcon]
@="C:/DGHOME/IPlusConf.exe,1"

[HKEY_CLASSES_ROOT\dgh\shell]

[HKEY_CLASSES_ROOT\dgh\shell\open]

[HKEY_CLASSES_ROOT\dgh\shell\open\command]
@="java -jar C:/DGHOME/Pch/lib/pch.teleconsulto.jar \"%1\""

On chrome this is enough. On Firefox, I had to add some configurations in about:config.Following MDN on Firefox I set the following

network.protocol-handler.expose.dgh;true
network.protocol-handler.external.dgh;true
network.protocol-handler.warn-external.dgh;false

In this way firefox at least ask to me if I want launch an application and ask to me to select one: I don't want that, I would it call the command I set and advise the first time the user about that:

On IE nothing happens, it says can't open the web page reference by my link.

Here a set of link I used as test

<a href="dgh://call/open?id='kit1.teleconsulto'">Open call to kit1.teleconsulto</a>
<a href="dgh://teleconsult/start?id='kit1.teleconsulto'">
   Open teleconsult to kit1.teleconsulto</a>
<a href="dgh://call/close">Close call</a>
<a href="dgh://call/end">Close client</a>
<a href="dgh://stethoscope/start">On Phonendo</a>

here some references: Installing and Registering Protocol Handlers http://msdn.microsoft.com/en-us/library/aa767916%28VS.85%29.aspx

I hope sincerely someone can help me

解决方案

The problem you're having is that the you're calling the jar directly in your protocol handler. You need to invoke java.exe with the -jar parameter

Your registry key should look like this

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\digitalmgi]
@="URL:digitalmgi protocol"
"URL Protocol"=""

[HKEY_CLASSES_ROOT\digitalmgi\DefaultIcon]
@="C:\\myCoolIcon.ico"

[HKEY_CLASSES_ROOT\digitalmgi\Shell]

[HKEY_CLASSES_ROOT\digitalmgi\Shell\Open]

[HKEY_CLASSES_ROOT\digitalmgi\Shell\Open\Command]
@="\"C:\\Program Files\\Java\\jre7\\bin\\java.exe\" -jar \"C:\\MyPath\\myJar.jar\" \"%1\""
