我正在寻找一个能够使用最新版本的安装程序进行自我更新的 NSIS 示例。

逻辑很简单：检查发布 URL 是否比当前可执行文件更新，然后下载它并使用相同的参数调用它自己。

主要是我会像“wget --timestamp URL”这样的东西，但到目前为止，我还没有找到任何 NSIS 文件下载扩展，它只有在更新文件时才能下载文件。

INetC::head will grab just the HTTP headers from the server but IMHO downloading a .ini file with version info from the server is better...

这是我写的一些东西，可能对你有帮助。我没有彻底测试过这个，但它在我运行的前几个测试中确实有效。这只是我为我正在从事的项目拼凑的一个例子。希望对你有用。=)
