使用 Kotlin 将参数放入请求 volley android

Question

我需要向 Volley 和 kotlin 提出请求，我的 cod 是

val stringReq = StringRequest(
Request.Method.GET, url,
Response.Listener<String> { response ->

var strResp = response.toString()
            val jsonObj: JSONObject = JSONObject(strResp)
            val jsonArray: JSONArray = jsonObj.getJSONArray("curso")

for (i in 0 until jsonArray.length()) {

                var jsonInner: JSONObject = jsonArray.getJSONObject(i)
                listGeral.add(jsonInner.get("interpret").toString());
                listGeral2.add(jsonInner.get("titel").toString());
                listGeral3.add(jsonInner.get("id").toString());

            }

},
        Response.ErrorListener {

        })
    queue.add(stringReq)

现在我需要为 php 发送 3 个参数。发送参数的指令怎么写？

你可以在Response.ErrorListener后面写下面的代码

      val sr: StringRequest = object : StringRequest(Method.POST, "url",
                Response.Listener { response -> 

                     //your response
              },
                Response.ErrorListener { error -> 
                     //your error
              }) {
            override fun getParams(): Map<String, String> {
                val params: MutableMap<String, String> = HashMap()
                params["user"] = "YOUR USERNAME"
                params["pass"] = "YOUR PASSWORD"
                return params
            }

            @Throws(AuthFailureError::class)
            override fun getHeaders(): Map<String, String> {
                val params: MutableMap<String, String> = HashMap()
                params["Content-Type"] = "application/x-www-form-urlencoded"
                return params
            }
        }
        queue.add(sr)
