android kotlin retrofit https post请求json参数请求服务器 rxjava+retrofit2
楼主心累呀，自己写了个项目玩都是get请求，还没玩过post，还要json参数。现在补充上来，坑都一个个填了
然后出现请求服务器一直404，各种找代码，各种看文档，各种走debug，最后发现是地址有问题。
“404，不是服务器问题么？”
此处省略一万字。。。。。
android kotlin retrofit https post请求json参数请求服务器 rxjava+retrofit2
1.配置环境
//配置Retrofit
compile 'com.google.code.gson:gson:2.2.4'
compile 'com.squareup.retrofit2:retrofit:2.1.0'
compile 'com.squareup.retrofit2:converter-gson:2.1.0'
//rxjava+retrofit2
compile 'io.reactivex:rxjava:1.3.0'
compile 'io.reactivex:rxandroid:1.2.1'
compile 'com.squareup.retrofit2:adapter-rxjava:2.1.0'
2.重点来了===上代码====
参数：{"service":"login","phoneNum":"17xxxxx2918"}
{
"service": "login",
"phoneNum": "17xxxxx2918"
}
val mMMService: MMMService
init {
val retrofit = Retrofit.Builder()
.baseUrl("http://192.168.18x.0x:8080/xxx/";)
.addConverterFactory(GsonConverterFactory.create())
.addCallAdapterFactory(RxJavaCallAdapterFactory.create())
.build()
mMMService = retrofit.create(MMMService::class.java!!)
}
#封装json数据 方法1#
val parm = JSONObject()
parm.put("service", "login")
parm.put("phoneNum", phone)
val requestBody = RequestBody.create(MediaType.parse("application/json"),
parm.toString())
// val paramBody = RequestBody.create(MediaType.parse("application/json;charset=UTF-8"),
// parm.toString())//将参数包装成RequestBody
val phoneCode = mMMService.getPhoneCodes(requestBody)
phoneCode.enqueue(callback)@Headers("Content-Type: application/json", "Accept: */*")//需要添加头
@POST("user.do")
fun getPhoneCodes(@Body route: RequestBody): Call //传入的参数为RequestBody
#封装json数据 创建bean 方法2#

override fun toString(): String {
return "LogonNetBean(service='$service', phone='$phoneNum')"
}
}

val gson = Gson()
val route = gson.toJson(bean)//通过Gson将Bean转化为Json字符串形式
val paramBody = RequestBody.create(MediaType.parse("application/json;charset=UTF-8"),
route)//将参数包装成RequestBody
val phoneCode = mMMService.getPhoneCodes(paramBody)
phoneCode.enqueue(callback)
#附加第二种请求方法#
