NSIS自动更新安装程序本身的示例？

nsis

NSIS自动更新安装程序本身的示例？,nsis,Nsis,我正在寻找一个NSIS的例子，能够更新自己的最新版本的安装程序 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 主要是像wget-timestamp URL这样的东西，但到目前为止，我找不到任何NSIS文件下载扩展名，只有在文件较新时才能下载文件。：：head将只从服务器获取HTTP头，但IMHO从服务器下载带有版本信息的.ini文件更好…我写了一些东西那可能对你有帮助。我还没有彻底测试过它，但在我运行的前几次测试中它确实起了作用。这只是我为一个项目准备

我正在寻找一个NSIS的例子，能够更新自己的最新版本的安装程序

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

主要是像wget-timestamp URL这样的东西，但到目前为止，我找不到任何NSIS文件下载扩展名，只有在文件较新时才能下载文件。

：：head将只从服务器获取HTTP头，但IMHO从服务器下载带有版本信息的.ini文件更好…

我写了一些东西那可能对你有帮助。我还没有彻底测试过它，但在我运行的前几次测试中它确实起了作用。这只是我为一个项目准备的一个例子。希望对你有用
