 RxAlamofire是包装，它围绕Swift 的优雅HTTP网络进行了。
将RxSwift包裹在Alamofire周围，使处理网络请求变得更加顺利和顺畅。 Alamofire是一个非常强大的框架，RxSwift添加了以简单有效的方式编写响应的功能。
 一个基本用法是（考虑一个简单的货币转换器）：
 let formatter = NSNumberFormatter ()
formatter. numberStyle = . currencyStyle
formatter. currencyCode = " USD "
if let fromValue = NSNumberFormatter (). numberFromString ( self . fromTextField . text ! ) {
RxAlamofire. requestJSON (.
				
使用Alamofire上传图片到阿里OSS时会发现有的时候上传失败，原因是因为Alamofire拼接form-data的时候顺序会出错，所以需要自己使用URLRequest自己进行拼接就可以。

IOS的Alamofire5.4高版本上传图片
Alamofire框架上传图片是比较冷门的知识。经常性报错，也找不到相关解释，或者其他低版本的写法，令开发者很是头疼。低版本的写法，在5.4.4API已经过期了。不在适用。我只用高版本的软件和最新软件。其他一概不用的。
那么5.4.4版本的Alamofire高版本的图片上传如何去写。我用springBoot后端去接受图片的上传的。swift是最新语法。把传入进来的图片转化成二进制。具体url是否传参，以及成功后是否搞一个回调函数通知调用者。自己完善一下。通过点
let image = UIImage(named: "xxx")
//将图片转化为JPEG类型的data 后面的参数是压缩比例
let jpegImage = UIImageJPEGRepresentation(image!, 0.5)
//要传的参数（比如我们带用户的加密uid）
 let u...

  public IHttpActionResult Upload()
            //   return Ok(new ApiRequestResult { ErrorCode = 1, Data = 0, ErrorMessage = "Return result Is fasle" });

Package.swift 是在 Swift Package Manager 中使用的一个文件，它用来描述一个 Swift 包的元数据，包括包的名称、版本、依赖等信息。在使用 SPM 创建、管理和使用 Swift 包时，通常需要在项目目录中创建一个 Package.swift 文件。
一个简单的 Package.swift 文件可能包含如下内容:
// swift-tools-version:5.3
import PackageDescription
let package = Package(
    name: "MyPackage",
    platforms: [
        .iOS(.v13),
        .macOS(.v10_15),
        .watchOS(.v6),
        .tvOS(.v13)
    products: [
        .library(
            name: "MyPackage",
            targets: ["MyPackage"]),
    dependencies: [
        // Dependencies declare other packages that this package depends on.
        // .package(url: /* package url */, from: "1.0.0"),
    targets: [
        // Targets are the basic building blocks of a package. A target can define a module or a test suite.
        // Targets can depend on other targets in this package, and on products in packages which this package depends on.
        .target(
            name: "MyPackage",
            dependencies: []),
        .testTarget(
            name: "MyPackageTests",
            dependencies: ["MyPackage"]),
在 Package.swift 文件中配置完成后,使用 swift package 相关命令就可以管理这个包了, 如 swift package init, swift package update, swift package generate-xcodeproj等
