我无法手动解析此JSONObject。

val client = OkHttpClient()
val mediaType = "application/x-www-form-urlencoded".toMediaTypeOrNull()
val body = RequestBody.create(mediaType, "query=${listItemName}")

val request = Request.Builder()
    .url("https://trackapi.nutritionix.com/v2/natural/nutrients")
    .method("POST", body)
    .build()

    val response = client.newCall(request).enqueue(object: Callback {
        override fun onFailure(call: Call, e: IOException) {
            println("Failed to execute request")
        }

        override fun onResponse(call: Call, response: Response) {
            val bodys = response.body?.string()
            println(bodys)

            val food = JSONObject(bodys)
            val foodName = food.getString("food_name")
          
        }


    })

system.out显示了JSONObject字符串，并且有一个“food_name”，但是我一直收到下面的错误

JSON响应为herex 1c 0d1x

val food = JSONObject(bodys).getJSONObject("foods")

这导致了错误
