创建AFHTTPSessionManager管理者对象

let afnManager = AFHTTPSessionManager()

Get请求

func getRequest() {

    afnManager.get("http://120.25.226.186:32812/login?username=520it&pwd=520it&type=JSON", parameters: nil, progress: { (progress:Progress) in
        print(progress)
    }, success: { (task:URLSessionDataTask, resposeObject:Any?) in
        print(task)
        print(resposeObject ?? "no respose object")
        print(Thread.current)
    }) { (task:URLSessionDataTask?, error:Error) in
        print(task ?? "no task")
        print(error)
        print(Thread.current)
    }

}

Post请求

func postRequest() {

let param = [
    "username" : "520it",
    "pwd" : "520it",
    "type" : "JSON"
]
afnManager.post("http://120.25.226.186:32812/login", parameters: param, progress: { (progress:Progress) in
    print(progress)
}, success: { (task:URLSessionDataTask, resposeObject:Any?) in
    print(task)
    print(resposeObject ?? "no respose object")
    print(Thread.current)
}) { (task:URLSessionDataTask?, error:Error) in
    print(task ?? "no task")
    print(error)
    print(Thread.current)
}

}

Download下载

func download() {

    let request = URLRequest(url: URL(string: "http://120.25.226.186:32812/resources/videos/minion_01.mp4")!)

    //从afnManager中得到一个URLSessionDownloadTask任务对象
    let downloadTask = afnManager.downloadTask(with: request, progress: { (progress:Progress) in

        //监视进度，progress.completedUnitCount：已下载数据大小，progress.totalUnitCount文件总数据大小
        print("\(Int(CGFloat(progress.completedUnitCount) * 1.0 / (CGFloat(progress.totalUnitCount) * 1.0) * 100))%")

    }, destination: { (targetPath:URL, response:URLResponse) -> URL in
        //如果不指定存储目录，下载的数据会被当做是一个临时对象缓存在tmp目录下，随时可能被系统清理
        print(targetPath)

        print(response)

        //所以我们要重新指定目录Document，如果希望文件长久保留。可以使用响应对象response中建议的文件名，
        let downloadPath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true).last?.appending("/\(response.suggestedFilename!)")

        //然后把这个重新指定的目录告诉AFN，文件就会指定存在这里了
        return URL(fileURLWithPath: downloadPath!)
    }) { (response:URLResponse, url:URL?, error:Error?) in
        print(response)
        print(url ?? "no url")
        if error != nil {
            print(error!)
        }
    }

    //最后记得让任务执行哦
    downloadTask.resume()
}

upload上传

func upload(){

    afnManager.post("http://120.25.226.186:32812/upload", parameters: nil, constructingBodyWith: { (formData:AFMultipartFormData) in
        //constructingBodyWith是一个AFMultipartFormData对象，可以将要上传的文件放在这里，比如一个文件或是一个二进制数据等
        try? formData.appendPart(withFileURL: URL.init(fileURLWithPath: "/Users/zhangfan/Pictures/2.jpg"), name: "file")
    }, progress: { (progress:Progress) in
        print("\(Int(CGFloat(progress.completedUnitCount) * 1.0 / (CGFloat(progress.totalUnitCount) * 1.0) * 100))%")
    }, success: { (task:URLSessionDataTask, responseObject:Any?) in
        print(task)
        print(responseObject ?? "no respose object")
        print((responseObject as! [String : Any])["success"]!)
        print(Thread.current)
    }) { (task:URLSessionDataTask?, error:Error) in
        print(task ?? "no task")
        print(error)
        print(Thread.current)
    }
