如标题中所述，我正尝试使用以下命令在批处理文件中下载jdk安装程序：
wget --verbose --show-progress --referer="https://download.oracle.com" --no-cookies --no-check-certificate --header "Cookie: oraclelicense=accept-securebackup-cookie" "https://download.oracle.com/otn-pub/java/jdk/15.0.1%2B9/51f4f36ad4ef43e39d0dfdbaf6549e32/jdk-15.0.1_windows-x64_bin.exe"我从批处理文件中得到以下错误：

当我在cli中直接使用此命令行（更改wget.exe文件所在的cd）时，它会正确下载安装程序，如下所示：

Saving to: 'jdk-15.0.1_windows-x64_bin.exe'我真的需要用这个命令一个脚本。
如果有人知道批处理文件和cli之间可能出了什么问题，我将非常感谢您的帮助。

比较输出中的URL。
cli url包含百分号
%2B作为url编码字母的一部分。但是批处理脚本输出缺少这个百分号，因此导致错误的url。cli输出
15.0.1%2B9批量输出15.0.1B9因为批处理使用百分号%要识别变量，你必须转义它，如果你想按字面意思使用它。因此，请尝试在批处理脚本中使用两个百分号
%%. 这将导致一个（正确的）单一的%在您的url中。
