# VMNetFramework

#### 介绍
纯kotlin 结合 retrofit + okhttp + liveData + ViewModel 实现的开发模式加网络框架

#### 软件架构
采用activity、fragment 和 liveData 绑定的模式发起网络请求，并且业务逻辑部分写在viewModel 中，网络请求使用retrofit，异步线程使用的是kotlin的协程的方式去实现的。

#### 使用说明

接收回调方式 及调用方式


    private lateinit var cityViewModel: CityViewModel

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        cityViewModel = createViewModel()

        getCity.setOnClickListener {
            cityViewModel.queryCityData()
        }

        jumpTest.setOnClickListener {
            cityViewModel.queryCity1Data()
        }
    }

    private fun createViewModel() : CityViewModel {
        return LViewModelProviders.of(this, CityViewModel::class.java).apply {
            oneLiveData.observe(this@MainActivity, Observer {
                println("wo shi shen 请求回来")
                tvContent.text = "第一个${Gson().toJson(it)}"
            })
            twoLiveData.observe(this@MainActivity, Observer {
                println("wo shi shen 请求回来")
                tvContent.text = "第二个${Gson().toJson(it)}"
            })
            errorLiveData.observe(this@MainActivity, Observer {
                if(it == true){
                    Toast.makeText(this@MainActivity, "服务异常", Toast.LENGTH_SHORT).show()
                } else {
                    Toast.makeText(this@MainActivity, "网络异常", Toast.LENGTH_SHORT).show()
                }
            })
        }
    }


viewModel 代码如下


    val oneLiveData: MutableLiveData<TestData> by lazy {
        MutableLiveData<TestData>()
    }

    val twoLiveData: MutableLiveData<TestData> by lazy {
        MutableLiveData<TestData>()
    }

    val errorLiveData: MutableLiveData<Boolean> by lazy {
        MutableLiveData<Boolean>()
    }

    fun queryCityData() {
        call {
            queryData(getDService().queryCity("1", "1.1.0"), object : RequestMultiplyCallback<TestData> {
                override fun onFail(e: BaseException) {
                    errorLiveData.value = e is ConnectionException
                }

                override fun onSuccess(t: TestData) {
                    oneLiveData.value = t
                }
            },true)
        }
    }

    fun queryCity1Data() {
        call {
            queryData(getDService().queryCity("1", "1.1.0"), object : RequestCallback<TestData> {
                override fun onSuccess(t: TestData) {
                    twoLiveData.value = t
                }
            })
        }

    }
