3. 数据获取与解析
注意:当然也可不用建立数据模型,没有数据模型时数据获取与解析可参考使用Alamofire与SwiftyJSON框架实现网络数据的获取与处理
import Just
var devices:[Device] = []
func getListByJust() {
let paras = ["userId":"128","companyId":"50"]
Just.post("https://api.uchat.com.cn/test/app", params: paras) { (r) in
guard let json = r.json as? NSDictionary else{
print("返回")
return
}
//let res = RootClass(fromDictionary: json).res!
let machineList = RootClass(fromDictionary: json).res.machineList!
//数组转换:map方法接受一个闭包作为参数, 然后它会遍历整个数组,并对数组中每一个元素执行闭包中定义的操作,相当于对数组中的所有元素做了一个映射.
self.devices = machineList.map{ (machi) -> Device in
return Device(deviceId: machi.machine.sn, deviceName: machi.machine.name, deviceStatus: machi.machine.status, deviceCount: "", deviceImage: machi.machine.image, date: machi.machine.addTime)
}
dump(self.devices)//打印
}
}
struct Device:Codable {
var deviceId:String
var deviceName:String
var deviceStatus:String
var deviceCount:String
var deviceImage:String
var date:String
}
