在macOS命令行工具项目中读取文件 [英] Read a file in a macOS Command Line Tool project

问题描述

我已经在我的macOS命令行工具项目中添加了一些JSON文件，但似乎无法以通常的方式找到它们。

I've added a few JSON files to my macOS Command Line Tool project, but I can't seem to find them the usual way.

if let path = Bundle.main.path(forResource: "Data", ofType: "json")
{
    if let contents = try? String(contentsOfFile: path)
    {
        print (contents)
    }
    else { print("Could not load contents of file") }
}
else { print("Could not find path") }

此代码在一个基于View的应用程序，但始终在命令行工具中显示找不到路径。

This code works absolutely fine when used in a View based application, but always prints "Could not find path" in the command line tool.

有人知道我在做什么吗？

Does anyone know what I'm doing wrong?

PS：完全意识到我应该为此使用 guard 语句，但是代码不在函数中，只是让人迷惑不解

P.S: Fully aware that I should be using guard statements for this, but the code isn't in a function, just faffing about in main.swift till I figure this out.

推荐答案

没有用于命令行工具的应用包。只是二进制文件。

There is no app bundle for a command-line tool. Just a binary.

您需要将JSON文件放在已知位置（当前目录？）并自己构建路径

You need to put the JSON file in a known location (current directory?) and construct the path yourself
