如何在 Kotlin 中使用 volley 将标题放在 url 中？

Question

我的代码-

val accessTokenRequest: JsonObjectRequest = JsonObjectRequest(Request.Method.GET, url,
            Response.Listener { response ->
            },
            Response.ErrorListener { error ->
                Toast.makeText(activity,error.toString(), Toast.LENGTH_LONG).show()
            }
    )

    AppController.instance!!.addToRequestQueue(accessTokenRequest)

我想放的标题 - “搜索”＆ “授权”

尝试使用以下代码添加标题

val accessTokenRequest: JsonObjectRequest = object : JsonObjectRequest(
    Request.Method.GET, "", JSONObject(),
    Response.Listener<JSONObject?> {
        TODO("not implemented") //To change body of created functions use File | Settings | File Templates.
    }, Response.ErrorListener {
    TODO("not implemented") //To change body of created functions use File | Settings | File Templates.
}) {
    @Throws(AuthFailureError::class)
    override fun getHeaders(): Map<String, String> {
        var params: MutableMap<String, String>? = super.getHeaders()
        if (params == null) params = HashMap()
        params["Authorization"] = "Your authorization"
        //..add other headers
        return params
    }
}

注意：要从 java 生成 kotlin 代码，请尝试使用 Ctrl + Shift + Alt + K 或简单地将其复制粘贴到 kotlin 文件中。
