如何在rust中解析 windows 的 lnk文件（快捷方式）

一、从标题二开始看😁

这些天在使用rust写一个pc端应用程序，需要解析lnk文件获取lnk的图标以及原程序地址，之前并没有过pc端应用程序开发的经验， 所以在广大的互联网上游荡了两天。额🥺

今天找到了这个库 lnk_parse很好的解决标题的这个问题。

二、文档及github地址

您可以在以下链接找到他：

• lib.rs（推荐）: https://lib.rs/crates/lnk_parser
• github（推荐）：https://github.com/abdulrhmanalfaifi/lnk_parser
• docs.rs（没有示例代码）: https://lib.rs/crates/lnk_parser

三、 使用

1. 在Cargo.toml文件中

   [dependencies]
   lnk_parser = "0.4.0" # 添加这行

2. 使用示例

use std::fs::File;
use std::io::Write;
use lnk_parser::LNKParser;

fn main() {
    let lnk_path = "example.lnk";
    let mut  file = File::open(lnk_path).unwrap();
    let lnk_file = LNKParser::from_reader(&mut file).unwrap();
    
    // 将结果转化成json文件输到./lnk.json中
    let json = serde_json::to_string(&lnk_file).unwrap();
    let mut output_file = File::create("./lnk.json").unwrap();
    output_file.write_all(json.as_bytes()).unwrap();
}

输出的json内容如下(这里复制的lnk_parse给出的示例)

                }
            }
        ]
    }
}

至于如何获取图标（看有注释那行）：

use std::fs::File;
use std::io::Write;
use lnk_parser::LNKParser;

fn main() {
    let lnk_path = "example.lnk";
    let mut  file = File::open(lnk_path).unwrap();
    let lnk_file = LNKParser::from_reader(&mut file).unwrap();
    let icon = lnk_file.get_icon_location(); // 使用这个方法就可以获取lnk的图标
    let mut icon_path:String;
    if let Some(path) = icon {
        icon_path = path.string.clone();
        println!("path: {:?}",  path.string);
    }
}
