CocoaHttpServer使用

我是怎么开始接触它的&＃xff1f;

公司前两天要做个项目类似于PP红包App Store应用刷榜项目&＃xff0c;需求是用户在safari中操作&＃xff0c;并且支持一下几点功能&＃xff1a;

1. 判断设备是否安装某app
2. 如果安装启动app
3. 获取到设备和网络信息
4. ...

很遗憾这些功能前端都做不了&＃xff0c;只能我开发一个助手&＃xff0c;帮助他完成以上功能。 大致的实现思路就是&＃xff0c;我把功能开发好&＃xff0c;在app启动时开启http服务&＃xff0c;他在safari中调用127.0.0.1:端口号/功能&＃xff0c;这种请求&＃xff0c;由我来执行相应的操作。 说明&＃xff1a;以上的1、2两点都是通过bundle id处理&＃xff0c;而非URL Scheme。

学习它能做啥&＃xff1f;

1. app开服务供本地的其他项目访问&＃xff08;例如&＃xff1a;safari&＃xff09;
2. 局域网内传文件
3. ...

怎么用&＃xff1f;

1. 下载CocoaHTTPServer

2. 导入CocoaHTTPServer-master目录下的Core、Vendor文件夹

3. 编辑如下代码&＃xff1a;

   let localHttpServer &＃61; HTTPServer()
localHttpServer.setType("_http.tcp")
// 设置端口
localHttpServer.setPort(53246)
localHttpServer.setConnectionClass(HTTPConnection.classForCoder())
do {try localHttpServer.start()print("开启成功")print(localHttpServer.listeningPort())
} catch {printLog(error)print("开启失败")
}


   现在是可以访问了&＃xff0c;那么怎么处理请求呢&＃xff1f;

处理本地请求

1. 创建HTTPConnection子类

2. 在子类中实现如下方法

   override func supportsMethod(_ method: String!, atPath path: String!) -> Bool {print("supportsMethod - method:\(method!) - path:\(path!)")return true
}override func expectsRequestBody(fromMethod method: String!, atPath path: String!) -> Bool {print("expectsRequestBody - method:\(method!) - path:\(path!)")return true
}override func httpResponse(forMethod method: String!, uri path: String!) -> (NSObjectProtocol & HTTPResponse)! {// 获取应用信息if path.hasPrefix("/getAppInfo") {do {let respDic &＃61; ["bundleIdentifier": Bundle.main.bundleIdentifier,"version": shortVersionString,"build": versionString,"appName": displayName] // 应用信息let respData &＃61; try JSONSerialization.data(withJSONObject: respDic, options: JSONSerialization.WritingOptions.init(rawValue: 0))return LYHTTPDataResponse(data: respData)} catch {}}return httpResponse(forMethod: method, uri: path)
}


注意&＃xff1a;

如果访问时出现跨域问题&＃xff0c;尝试添加如下代码&＃xff1a;

override func httpHeaders() -> [AnyHashable : Any]! {return ["Content-type": "*","Access-Control-Allow-Origin": "*","Access-Control-Allow-Credentials": "true","Access-Control-Allow-Methods": "POST, GET, OPTIONS","Access-Control-Max-Age": "3600","Access-Control-Allow-Headers": "Origin, Referer, User-Agent, Accept"]
}
