使用相同的命令可以正常下载其他文件...
这是我试过的
"%~dp0wget" -c --show-progress --progress=bar:force:noscroll --no-check-certificate "https://download.microsoft.com/download/E/A/E/EAE6F7FC-767A-4038-A954-49B8B05D04EB/ExpressAdv%2064BIT/SQLEXPRADV_x64_ENU.exe" -P C:\Temp
..和..
"%~dp0wget" -c --show-progress --progress=bar:force:noscroll --no-check-certificate https://download.microsoft.com/download/E/A/E/EAE6F7FC-767A-4038-A954-49B8B05D04EB/ExpressAdv%2064BIT/SQLEXPRADV_x64_ENU.exe -P C:\Temp
我希望这是处理链接中 % 的报价问题，但没有成功。我也试过单引号，并在 % 前面放一个\来转义字符。
总是同样的错误。我想知道这个站点上的 wget 请求是否有一些服务器端限制。我可以绕过它吗？也许我需要一些其他开关？提前致谢。
最佳答案
当简单地从 cmd 运行时，您的命令可以工作，但是由于您是从批处理文件中运行它，您需要通过将百分号加倍来转义百分号，即:% → %%
这给出了:
"%~dp0wget" -c --show-progress --progress=bar:force:noscroll --no-check-certificate "https://download.microsoft.com/download/E/A/E/EAE6F7FC-767A-4038-A954-49B8B05D04EB/ExpressAdv%%2064BIT/SQLEXPRADV_x64_ENU.exe" -P C:\Temp
引用ss64.com :
Many characters such as \ = ( ) do not need to be escaped when they are used within a "quoted string" typically these are charcters you might find in a filename/path. The percent character is one exception to this rule, even though under NTFS % is a valid filename character.
