在 uiThread 中获取燃料结果

Question

我使用一个名为"Fuel"的库从服务器获取数据，这是我的代码：

button1.setOnClickListener {
val jb = "{......}"
Fuel.post("server_url")
.header(Headers.CONTENT_TYPE, "application/json")
.body(jb)
.response { request, response, result ->
Log.d("test", request.toString())
Log.d("test", response.toString())
val (bytes, error) = result
if (bytes != null) {
val e = JsonParser().parse(String(bytes))
val obj = e.asJsonObject
val rm = obj.get("rm").asString
}
}
}

但问题是：如何获得"rm"的值？

它是在燃料函数中定义的，我无法从燃料之外获得它的值......

有人可以帮我如何获得它吗？

您可以在响应对象外部声明var并设置值

var globalRM : String? = null;
button1.setOnClickListener {
val jb = "{......}"
var rm : String? = null;
Fuel.post("server_url")
.header(Headers.CONTENT_TYPE, "application/json")
.body(jb)
.response { request, response, result ->
Log.d("test", request.toString())
Log.d("test", response.toString())
val (bytes, error) = result
if (bytes != null) {
val e = JsonParser().parse(String(bytes))
val obj = e.asJsonObject
globalRM = obj.get("rm").asString
rm = obj.get("rm").asString
}
}
}

您可能还想在获取值后立即执行某些操作，在这种情况下，请创建一个方法并使用它：

onCreate(...){
button1.setOnClickListener {
val jb = "{......}"
var rm : String? = null;
Fuel.post("server_url")
.header(Headers.CONTENT_TYPE, "application/json")
.body(jb)
.response { request, response, result ->
Log.d("test", request.toString())
Log.d("test", response.toString())
val (bytes, error) = result
if (bytes != null) {
val e = JsonParser().parse(String(bytes))
val obj = e.asJsonObject
globalRM = obj.get("rm").asString
rm = obj.get("rm").asString
onFuelFetched(rm)
}
}
}
}
fun onFuelFetched(val rm:String?){
// do anything you wish to do with this value here
}
