Gruntjs 如何将参数传递给grunt任务？

我想重构我的grunt复制任务，以避免在多个子任务中重复相同的文件。现在看起来是这样的：

    "copy":
    {
        "web-debug":
        {
            files:
            [
                { src: "libs/1st/**/*", dest: config.buildWebDebugOutPath },
                { src: "libs/3rd/**/*", dest: config.buildWebDebugOutPath },
                { src: "assets/**/*", dest: config.buildWebDebugOutPath },
                { src: "shared/**/*", dest: config.buildWebDebugOutPath },
                { src: "client/**/*", dest: config.buildWebDebugOutPath },
            ]
        },     
        "web-release":
        {
            files:
            [
                { src: "libs/1st/**/*", dest: config.buildWebReleaseOutPath },
                { src: "libs/3rd/**/*", dest: config.buildWebReleaseOutPath },
                { src: "assets/**/*", dest: config.buildWebReleaseOutPath },
                { src: "shared/**/*", dest: config.buildWebReleaseOutPath },
                { src: "client/**/*", dest: config.buildWebReleaseOutPath },
            ]
        },        

理想情况下，我只有一个复制任务，它接受一个路径参数，我可以通过别名任务传递给它，如下所示：

//
// Let's assume I renamed "web-debug" to "web-files"
//
grunt.registerTask("web-debug", ["web-files:<some debug path>"]);
grunt.registerTask("web-release", ["web-files:<some release path>"]);

"copy":
{
    "web-files":
    {
        files:
        [
            { src: "libs/1st/**/*", dest: "<%= grunt.task.current.args[0] %>" },
            { src: "libs/3rd/**/*", dest: "<%= grunt.task.current.args[0] %>" },
            { src: "assets/**/*", dest: "<%= grunt.task.current.args[0] %>" },
            { src: "shared/**/*", dest: "<%= grunt.task.current.args[0] %>" },
            { src: "client/**/*", dest: "<%= grunt.task.current.args[0] %>" },
        ]
    }

//
//假设我将“web调试”重命名为“web文件”
//
registerTask（“web调试”，“web文件：”）；
registerTask（“web发布”，“web文件：”）；

最简单的方法是什么

如何访问任务本身中传入的参数？

您可以使用模板，如本文所述。在代码的上下文中，它可能如下所示：

//
// Let's assume I renamed "web-debug" to "web-files"
//
grunt.registerTask("web-debug", ["web-files:<some debug path>"]);
grunt.registerTask("web-release", ["web-files:<some release path>"]);

"copy":
{
    "web-files":
    {
        files:
        [
            { src: "libs/1st/**/*", dest: "<%= grunt.task.current.args[0] %>" },
            { src: "libs/3rd/**/*", dest: "<%= grunt.task.current.args[0] %>" },
            { src: "assets/**/*", dest: "<%= grunt.task.current.args[0] %>" },
            { src: "shared/**/*", dest: "<%= grunt.task.current.args[0] %>" },
            { src: "client/**/*", dest: "<%= grunt.task.current.args[0] %>" },
        ]
    }

“复制”：
{
“web文件”：
{
文件夹：
[
{src:“libs/1st/***”，dest:“}，
{src:“libs/3rd/***”，dest:“}，
{src:“资产/****”，目标：}，
{src:“shared/***”，dest:}，
{src:“client/***”，dest:}，
]
}

您可以传入完整路径，也可以只传入部分“调试”或“发布”路径段
