Android okhttp网络请求封装 结合协程简单使用Kotlin版（2）
直接上代码：
OkhttpUtils：
class OkhttpUtils {
companion object{
private var instance:OkhttpUtils? = null
private var okhttp:OkHttpClient? = null
@Synchronized
fun getInstance():OkhttpUtils{
if (instance == null) instance = OkhttpUtils()
okhttp = OkHttpClient().newBuilder()
.retryOnConnectionFailure(true)
.connectTimeout(10000, TimeUnit.SECONDS) //连接超时
.readTimeout(10000, TimeUnit.SECONDS) //读取超时
.writeTimeout(10000, TimeUnit.SECONDS) //写超时
.build()
return instance!!
}
}
/**
* Get请求
* @map 请求参数 map的key必须不同
* @url 请求地址
* @httpCallBack 回调
*/
fun getRequest(map:HashMap,url:String,httpCallBak:HttpCallBack){
if (TextUtils.isEmpty(url)){ return }
var urlRequest:String = ""
var urlL:String = ""
if (map.size > 0){
val list = ArrayList(map.keys)
urlL = "$url?"
for (key in map.keys){
urlRequest += if (list[map.size - 1].equals(key)){
key + "=" + map[key]
}else{
key + "=" + map[key] + "&"
}
}
urlL += urlRequest
}
val request: Request = Request.Builder().url(urlL).build()
val call: Call? = okhttp?.newCall(request)
call?.enqueue(object : Callback {
override fun onFailure(call: Call, e: IOException) {
val error:String = e.printStackTrace().toString();
//一定要Dispatchers.Main 不然协程不会切换线程
GlobalScope.launch(Dispatchers.Main) {
httpCallBak.onError(error)
}
}
override fun onResponse(call: Call, response: Response) {
val body: String? = response.body?.string();
response.body?.let {
//一定要Dispatchers.Main 不然协程不会切换线程
GlobalScope.launch(Dispatchers.Main) {
body?.let { it1 ->
httpCallBak.onSuccess(it1)
}
}
}
}
})
}
/**
* Post请求
* @map 请求参数
* @url 请求地址
* @httpCallBack 回调
*/
fun postRequest(map:HashMap,url:String,httpCallBak:HttpCallBack){
if (TextUtils.isEmpty(url)){ return }
var builder: FormBody.Builder = FormBody.Builder();
if (map.size > 0){
for (key in map.keys){
key.let {
builder.add(it, map[it].toString())
}
}
}
val formBody:FormBody = builder.build()
val request: Request = Request.Builder().url(url)
.post(formBody)
.build()
val call: Call? = okhttp?.newCall(request)
call?.enqueue(object : Callback {
override fun onFailure(call: Call, e: IOException) {
val error:String = e.printStackTrace().toString();
//一定要Dispatchers.Main 不然协程不会切换线程
GlobalScope.launch(Dispatchers.Main) {
httpCallBak.onError(error)
}
}
override fun onResponse(call: Call, response: Response) {
val body: String? = response.body?.string();
response.body?.let {
//一定要Dispatchers.Main 不然协程不会切换线程
GlobalScope.launch(Dispatchers.Main) {
body?.let { it1 ->
httpCallBak.onSuccess(it1)
}
}
}
}
})
}
}
gradle引入：
//引入json解析框架
implementation ‘com.alibaba:fastjson:1.1.72.android’
//协程
implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-core:1.3.2'
implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-android:1.3.2'
JsonUtils：
class JsonUtils {
companion object {
/**
* 解析json写法
*/
fun getJson(json: String?, clazz: Class?): RequestBodyContent? {
return JSONObject.parseObject(json, object : TypeReference
}
/**
*实际使用方法解析json
*/
fun getJsonContent(json: String?,clazz: Class?):RequestBodyContent?{
if (!TextUtils.isEmpty(json)){
return getJson(json,clazz)
}
return null
}
}
}
使用方法：PeopleBean是实体类最里面一层 RequestBodyContent是最外面一层
with(OkhttpUtils) {
getInstance().postRequest(map, “https://www.baidu.com/”, object : HttpCallBack {
override fun onError(errorLog: String) {
Toast.makeText(getApplication(),errorLog,Toast.LENGTH_SHORT).show()
}
override fun onSuccess(message: String) {
var content: ? = JsonUtils.getJson(message,PeopleBean::class.java)
Toast.makeText(getApplication(),message,Toast.LENGTH_SHORT).show()
}
})
}
