在 Windows 10 上尝试获取默认 Web 浏览器路径失败 [英] Trying to get default web browser path fails on Windows 10

问题描述

我正在我的应用安装程序中执行以下操作(请注意，此项目的安装程序只是一个 Windows 可执行文件 (setup.exe) 而不是 MSI.)

I'm doing the following in my app's installer (note that the installer for this project is just a Windows executable (setup.exe) and not an MSI.)

首先我需要检查 .htm 和 .html 文件类型是否存在文件关联.我已经这样做了.然后，如果没有关联，我需要添加它们以通过网络浏览器打开.

First I needed to check if there're file associations for .htm and .html file types. I did so already. And then if there's no association I needed to add them to be opened by a web browser.

为了减少对用户系统的影响，我想使用用户的默认网络浏览器.问题是如何找到它的路径?

To make a lesser of an impact on a user's system, I thought to go with the user's default web browser. The question is how to find its path?

所以我是这样做的:

//Get default web browser path
WCHAR wbuffPath[MAX_PATH] = {0};
DWORD dwszBuffPath = MAX_PATH;
::AssocQueryStringW(0, ASSOCSTR_EXECUTABLE, L"http", L"open", wbuffPath, &dwszBuffPath);

这似乎有效，除非我在 Windows 10 上运行它时我得到这个路径(当默认为 Edge 浏览器时):

which seems to work, except when I run it on Windows 10 I get this path (when default is the Edge browser):

C:\WINDOWS\system32\LaunchWinApp.exe

C:\WINDOWS\system32\LaunchWinApp.exe

那么我如何重置参数以启动它?

So how do I get the reset of the parameters to start it?

推荐答案

尝试使用 ASSOCSTR_COMMAND 而不是 ASSOCSTR_EXECUTABLE.通过使用ASSOCSTR_EXECUTABLE，您要求只是 可执行文件本身，这正是您要返回的内容.ASSOCSTR_COMMAND 应该为您提供可执行文件的整个命令行.

Try using ASSOCSTR_COMMAND instead of ASSOCSTR_EXECUTABLE. By using ASSOCSTR_EXECUTABLE, you are asking for just the executable by itself, which is exactly what you are getting back. ASSOCSTR_COMMAND should give you the whole command line for the executable.
