Double-Quotes in start line of Windows Batch script
提问by Anthony
I have looked at the answers already provided, but I'm still stuck. Here is what I currently have:
我已经查看了已经提供的答案，但我仍然被卡住了。这是我目前拥有的：
start "" "C:\Program Files (x86)\Spark\Spark.exe"
echo Spark started
This works fine. But now I want to pass parameters to the client, which must be wrapped in quotes. I can do the following on the command line:
这工作正常。但是现在我想将参数传递给客户端，必须用引号括起来。我可以在命令行上执行以下操作：
"C:\Program Files (x86)\Spark\Spark.exe" "user=%USERNAME%&server=example.org"
And it starts up with the user and server fields filled in.
它以填充的用户和服务器字段启动。
But when I try to edit the batch script to add those quote-wrapped parameters, I get a variety of errors depending on how I try to add double-quotes and where, etc.
但是当我尝试编辑批处理脚本以添加那些引号包裹的参数时，根据我尝试添加双引号的方式和位置等，我会收到各种错误。
So how would I add a quote-wrapped parameter to the start line?
那么我如何将引号包裹的参数添加到起始行？
Update:
更新：
I accidentally got it to work, but haven't been able to reproduce it. But it didn't work exactly right. The user name was still blank, but the server was filled in. I forgot to mention that I am using an environment variable for the user name: %USERNAME%
我不小心让它工作了，但一直无法重现它。但它并没有完全正确。用户名还是空的，但是服务器是填的。 忘了说我用的用户名是环境变量： %USERNAME%
So it might be my problem is that I can't escape quotes and use environment variables?
所以可能是我的问题是我无法转义引号并使用环境变量？
Final Answer:
最终答案：
It turns out that part of the problem was that I was using the wrong parameter, but originally I had been using the right one, so I didn't notice. From the command line, I should have:
原来问题的一部分是我使用了错误的参数，但最初我一直在使用正确的参数，所以我没有注意到。从命令行，我应该有：
"C:\Program Files (x86)\Spark\Spark.exe" "username=%USERNAME%&server=example.org"
and so from the batch file, the following works:
因此从批处理文件中，以下工作：
start "" "C:\Program Files (x86)\Spark\Spark.exe" "username=%USERNAME%&server=example.org"
echo Spark started
Much thanks and points to dcp for getting me to the right answer.
非常感谢并指出 dcp 让我得到正确答案。

Did you try this?
你试过这个吗？
"C:\Program Files (x86)\Spark\Spark.exe" "\"user=foo&server=example.org\""
This worked when I tried a simple command line test and c++ program (I could see the quotes when I printed the argv[1] argument).
当我尝试一个简单的命令行测试和 c++ 程序时（当我打印 argv[1] 参数时我可以看到引号），这很有效。
UPDATE:If %USERNAME% has spaces in it, then you need to quote it like this (see below). I think you can remove the other quotes.
更新：如果 %USERNAME% 中有空格，那么您需要像这样引用它（见下文）。我认为您可以删除其他引号。
"C:\Program Files (x86)\Spark\Spark.exe" user="%USERNAME%"&server=example.org
