关于使用rust调用c++静态库并编译nodejs包的问题

2024-10-15 23:06:34

在项目上经常要用到身份证阅读器、护照阅读仪、指纹仪等各种品牌硬件，假如每套系统的都做集成开发那代码的维护成本将变得很高，为此采用rust来调用厂家提供的sdk c++开发包并封装成nodejs包，用fastify来开发成web api独立的服务形式。这样我们开发系统时只需调用web接口即可，跨平台又可共用，方便快捷，话不多说来看代码如何实现。

一、创建项目

安装rust后，打开vs新建一个工程目录，我们通过cargo new创建的一个package项目，加上--lib参数后创建的项目就是库项目（library package）。
cargo new --lib reader
package 就是一个项目，因此它包含有独立的 Cargo.toml 文件，用于项目配置。库项目只能作为三方库被其它项目引用，而不能独立运行，即src/lib.rs。
典型的package
如果一个 package 同时拥有 src/main.rs 和 src/lib.rs，那就意味着它包含两个包：库包和二进制包，这两个包名也都是 test_math —— 都与 package 同名。
一个真实项目中典型的 package，会包含多个二进制包，这些包文件被放在 src/bin 目录下，每一个文件都是独立的二进制包，同时也会包含一个库包，该包只能存在一个 src/lib.rs：
.
├── Cargo.toml
├── Cargo.lock
├── src
│ ├── main.rs
│ ├── lib.rs
│ └── bin
│ └── main1.rs
│ └── main2.rs
├── tests
│ └── some_integration_tests.rs
├── benches
│ └── simple_bench.rs
└── examples
└── simple_example.rs

唯一库包：src/lib.rs
默认二进制包：src/main.rs，编译后生成的可执行文件与package同名
其余二进制包：src/bin/main1.rs 和 src/bin/main2.rs，它们会分别生成一个文件同名的二进制可执行文件
集成测试文件：tests 目录下
性能测试benchmark文件：benches 目录下
项目示例：examples 目录下
这种目录结构基本上是 Rust 的标准目录结构，在 github 的大多数项目上，你都将看到它的身影。
运行Cargo build命令，我们在target\debug目录下可以看到编译后的结果。

二、Cargo.toml

[package]
name = "reader"
version = "0.1.0"
edition = "2018"
exclude = ["reader.node"]
# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
libc = "0.2.9"
libloading = "0.7"
once_cell = "1.8"
serde = { version = "1.0", features = ["derive"] }
widestring = "0.5.1"
serde_json = "1.0"
base64 = "0.13"
hex="0.4.2"
encoding = "0.2"
tokio={version="1.18.0",features = ["full"]}

[dependencies.neon]
version = "0.9"
default-features = false
features = ["napi-5", "channel-api"]

[lib]
crate-type = ["cdylib"]

三、package.json

{
  "name": "reader",
  "version": "0.1.0",
  "description": "",
  "main": "index.node",
  "scripts": {
    "build": "cargo-cp-artifact -nc index.node -- cargo build --message-format=json-render-diagnostics",
    "build-debug": "npm run build --",
    "build-release": "npm run build -- --release",
    "build_win32": "npm run build -- --release --target=i686-pc-windows-msvc",
    "test": "cargo test",
    "run": "cargo run"
  },
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "cargo-cp-artifact": "^0.1"
  },
  "dependencies": {
    "express": "^4.17.3"
  }
}

我们可以打印rust看看编译输出支持哪些架构
rustc --print target-list
//添加 x86编译链接器
rustup target add i686-pc-windows-msvc

C++的替代：微软如何使用rust？

微软拥有世界上最大的C/C++代码库之一.从Windows.Office到Azure云,微软的所有核心产品都在该代码库上运行.但因为C++不是内存安全的语言,代码库中自然频频出现内存漏洞,大量的时间被耗费在修补漏洞上. 微软自去年开始寻找用以替代的编程语言来解决内存安全问题,寻找终有所得--微软开始尝试使用Rust,并在一些情境下将其集成进代码库中.Rust是一种相对较新的编程语言,具有与C和C++相同的底层性能,并具备现代编程语言应有的功能集. 微软认为Rust颇具潜力,本文就将介绍微软将其用

如何正确使用Nodejs 的 c++ module 链接到 OpenSSL

事情的起因是这样的, 因为某些原因, 最近在写 Nodejs 的 c++ module, 然后在js这边调用. 网络通信自然离不开ssl, 于是需要链接到Openssl的库. 我们本来的期望是,需要用户安装有Openssl的运行库, 然后我们的c++ module 动态链接到Openssl的so库上来运行. 起初一切看起来还不错,直到我们发现这个openssl的函数不能工作: PKCS7_sign() PKCS7_sign ( ) 我们发现: 如果我们的 c++ 模块与Openssl库动态链接

iOS创建与使用静态库

在日常项目开发中,不论是为了两个公司项目上的业务交流还是为了减少项目的编译时间,有的时候我们会把项目中的私密内容打包成静态库,或者是把项目中变动较少一部分打包成静态库以便提高编译效率,那么下面我们就来学习一下"iOS-静态库的创建与使用": (一)iOS静态库.动态库与Framework静态库与动态库的区别 (1)什么是库? 库(Library)直白一点说就是一段编译好的二进制代码,加上头文件就可以供别人使用;(例如: iOS中Objective-C编译下的.h和.m文件,打包静态库后
