自定义协议从浏览器中启动本地应用程序

1. 需要启动的本地应用程序为:

e:\SRC\Test\MyApp\bin\Debug\MyApp.exe

2. 编辑注册表导入文件: MyApp_Disk_D.reg

内容如下:

[plain] view plain copy

Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\myapp]
@="URL:AutoHotKey myapp Protocol"
"URL Protocol"=""
[HKEY_CLASSES_ROOT\myapp\DefaultIcon]
@="myapp.exe,1"
[HKEY_CLASSES_ROOT\myapp\shell]
[HKEY_CLASSES_ROOT\myapp\shell\open]
[HKEY_CLASSES_ROOT\myapp\shell\open\command]
@="\"e:\\SRC\\Test\\myapp\\bin\\Debug\\myapp.exe\" \"%1\""

3. 将上面的文件导入到注册表.

4. 在IE中输入如下内容,即可启动应用程序myapp.exe

[plain] view plain copy

myapp://parameter

5. 至此在大多数浏览器中,已经能够通过自定义的协议启动指定应用程序了.

6. 对于Chrome浏览器,若不能启动指定的应用,请查看如下几点

6.1 自定义协议后的参数不能太短,最好超过三个字符,并且最好不要用一些常用的关键字.

6.2 配置Chrome的阻止的协议列表, 配置文件路径如下,不用的安装路径,还不用的用户,路径稍有不同:

C:\Users\liu\AppData\Local\Google\Chrome\User Data\Local State

打开此文件后,找到如下内容:

[plain] view plain copy

"protocol_handler":
{
"excluded_schemes":
{
"afp":true,
"data":true,
"disk":true,
"disks":true,
"file":true,
"hcp":true,
"iview":false,
"javascript":true,
"mailto":false,
"ms-help":true,
"ms-windows-store":false,
"myapp":false,
"news":false,
"nntp":true,
"shell":true,
"snews":false,
"tencent":false,
"vbscript":true,
"view-source":true,

确保我们自己定义的协议 myapp 后面的值为"false", 即不在被排除的列表中.

7. 通过网页中的连接打开本地相关应用程序的示例如下

[html] view plain copy

<!DOCTYPE html>
<html>
<head>
<title>Web Automation</title>
<script type="text/javascript">
function dicom() {
var ret = confirm('Start Dicom Search？');
var aetitle = document.getElementById("txtAETitle").value;
var patientid = document.getElementById("txtPatientId").value;
var accessnumber = document.getElementById("txtAccessionNumber").value;
var local = document.getElementById("cbLocal").checked;
if (ret == true) {
window.location = 'myapp://,query,' + aetitle + ',' + patientid + ',' + accessnumber + ',' + local;
}
return;
};
function study() {
var ret = confirm('Open Study？');
var aetitle = document.getElementById("txtAETitle").value;
var studyInstanceUId = document.getElementById("txtStudyInstanceUId").value;
if (ret == true) {
window.location = 'myapp://,study,' + aetitle + ',' + studyInstanceUId;
}
return;
};
function LaunchApp() {
try {
var ret = confirm('Start myapp？');
if (ret == true) {
window.location = 'myapp://,start';
}
}
catch (ex) {
errMsg = "启动 myapp 报错.\n\n";
alert(errMsg);
}
return;
};
</script>
<style type="text/css">
#txtAccessionNumber
{
width: 191px;
}
#txtStudyInstanceUId
{
width: 901px;
}
</style>
</head>
