批处理脚本选择分支未执行问题咨询：请求排查语法错误

Let's walk through the key syntax and logic problems that are preventing your if blocks from running correctly:

1. Variable Definition Has Extra Spaces #

Your line set /P var = "What is your option a or b" has a critical issue: the space between var and = means the actual variable name created is var (with a trailing space), not var. When you reference %var% later, it's empty—so your if conditions never match "A" or "B".

Fix: Remove the spaces around the equals sign:

set /P var="What is your option a or b: "

2. Invalid Command Parameter in the Second if Block #

You have a misplaced space in - mode:edit—the hyphen and mode should be joined together as -mode:edit. Extra spaces here will confuse the infordbcl.exe command and cause it to fail (or not run as intended).

3. Working Directory Mismatch #

The first if block changes directories to C:\Program Files\Infor\Mongoose\Tools, but the second if block doesn't. If infordbcl.exe isn't in your system's PATH, the second command won't find the executable.

Fix: Move the cd command outside both if blocks to ensure both operations run in the correct directory:

cd /d "C:\Program Files\Infor\Mongoose\Tools"

(The /d flag ensures it switches drives if needed.)

4. Case Sensitivity for User Input #

Right now, your script only recognizes uppercase "A" or "B"—if the user enters lowercase "a" or "b", the conditions won't trigger.

Fix: Add the /i flag to your if statements to make matches case-insensitive:

if /i "%var%" == "A" (...)

Full Corrected Script #

Here's the revised version with all fixes applied, plus a basic invalid input check:

@echo off
setlocal enabledelayedexpansion
echo What operation would you like to perform?
echo a: Create a new web server
echo or
echo b: Edit root URL for an existing web server
set /P var="Enter your option (a/b): "

:: Handle invalid input
if /i not "%var%"=="a" if /i not "%var%"=="b" (
    echo Invalid option! Please run the script again and enter 'a' or 'b'.
    pause
    exit /b 1
)

cd /d "C:\Program Files\Infor\Mongoose\Tools"
if /i "%var%" == "A" (
    infordbcl.exe addwebserver -name:sample -product:Mongoose -rooturl:https://uscovwmongoose3
)
if /i "%var%" == "B" (
    infordbcl.exe addwebserver -name:sample -product:Mongoose -rooturl:https://mongoose.com -mode:edit
)
endlocal
