Question

将单个参数传递给我的Windows安装程序时，

MyApplication.exe CLIENT="Your Mom"

我可以使用GetParameters和GetOptions正确阅读，如下所示：

${GetParameters} $0
${GetOptions} "$0" "CLIENT=" $CLIENT

但是一旦我尝试传递多个参数

MyApplication.exe CLIENT="Your Mom" NAME="Jill" LOCATION="Da Yard" TEL="0221456789"

并试着像这样阅读

${GetParameters} $0
${GetOptions} "$0" "CLIENT=" $CLIENT 
${GetOptions} "$0" "NAME=" $NAME 
${GetOptions} "$0" "LOCATION=" $LOCATION 
${GetOptions} "$0" "TEL=" $TEL

$CLIENT，$NAME和$TEL的值是正确的，但$LOCATION将包含

Da Yard TEL=0221456789

如果我添加更多参数，同样的情况会发生，前两个参数总是正确的，但两者之间的参数总是包含传递给安装程序的字符串的子字符串。

我正确使用GetOptions吗？

Answer 1

如果您更改了所有参数，以便它们以/开头，那么它可以正常运行！（ MyApplication.exe / CLIENT =“你的妈妈”/ NAME =“Jill”/ LOCATION =“Da Yard”/ TEL =“0221456789”和${GetOptions} "$0" "/LOCATION=" $LOCATION）

如果你不能使用/ switch前缀，那么你必须自己重写$ {GetOptions}或等到下一个NSIS版本，希望它能被修复。

如果你想自己修一下它，那就看起来像这样：

!include FileFunc.nsh

!macroundef GetOptionsBody

!macro GetOptionsBody _FILEFUNC_S
Exch $1 ; Prefix
Exch
Exch $0 ; String
Exch
ClearErrors

; Parse $0 here and look for $1 and store the suffix in $0...


FileFunc_GetOptions${_FILEFUNC_S}_notfound:
    SetErrors
    StrCpy $0 ''

FileFunc_GetOptions${_FILEFUNC_S}_end:

Pop $1
Exch $0
!macroend

似乎这可能是设计上的，帮助文件包含这个有点破碎的英文小贴士：

第一个选项符号是分隔符

我从头开始创建一个新的GetOptions，它只支持双引号，并且可能在各种方式上有所不同。我没有测试太多，但似乎工作正常：

Outfile "Test.exe"

!include FileFunc.nsh
