在c#项目中部署CasperJS

本文关键字：部署 CasperJS 项目 | 更新日期: 2023-09-27 18:15:24

Tl:dr -我如何从c#项目文件夹中引用CasperJS和PhantomJS ?

当我手动解压缩CasperJS和PhantomJS的二进制文件到C:驱动器时，我已经得到了从c#项目运行CasperJS脚本的工作代码。(请看这里有一个简单的指南和下面标有工作代码的工作代码:)

由于不需要安装，我认为将这些移动到c#项目文件夹而不是'tools'casperjs和'tools'phantomjs会很容易。此外，我需要使用p.StartInfo.EnvironmentVariables["PATH"] = EnvPath;

更新代码中的PATH变量

我尝试的所有路径组合，我一直得到以下错误"Fatal: [Errno 2] No such file or directory; did you install phantomjs?"

所有文件都明确包含在文件路径中。我错过了什么明显的东西吗?

非工作代码: [fileppaths 'tools'casperjs， 'tools'phantomjs &C: ' Python34]

casper.thenOpen('http://phantomjs.org', function() {

搞定了。只要确保所有必需的资产都被正确地复制过来。我错过了文件路径C:'casperjs'n1k0-casperjs-4f105a9
