json - 如何在 Kotlin 的 Volley 请求中在 Url 中添加正文？

Question

这是我用于 Volley 请求的代码:-

    val searchRequest = object : JsonArrayRequest(Request.Method.GET,url,
            Response.Listener { response ->

                val result = response.toString()


            },
            Response.ErrorListener { error ->
                Toast.makeText(activity, "Error!",Toast.LENGTH_LONG)
                        .show()
                Log.d("ERROR",error.toString())
            })
    {
        override fun getBody(): ByteArray {

           //   TODO add Body, Header section works  //////////

            return super.getBody()
        }

        override fun getBodyContentType(): String {
            return "application/json"
        }


        override fun getHeaders() : Map<String,String> {
            val params: MutableMap<String, String> = HashMap()
            params["Search-String"] = songName
            params["Authorization"] = "Bearer ${accessTx.text}"
            return params
        }
    }
    AppController.instance!!.addToRequestQueue(searchRequest)

我想在正文部分添加此信息

video_id = "BDJIAH",
音频质量=“256”

这是在以下部分中添加上述信息的示例。

{
"video_id":"ABCDE",
“音频质量”:“256”
}

基本上，我在 ByteArray 部分遇到了问题。那对我不起作用。

我创建的这个函数是为了向服务器发送调用，这就是您在调用中添加正文的方式。

    fun sendcall() {
            //RequestQueue initialized
            mRequestQueue = Volley.newRequestQueue(this)

           //String Request initialized
            mStringRequest = object : StringRequest(Request.Method.POST, url, Response.Listener { response ->
                Toast.makeText(applicationContext, "Logged In Successfully", Toast.LENGTH_SHORT).show()


            }, Response.ErrorListener { error ->
                Log.i("This is the error", "Error :" + error.toString())
                Toast.makeText(applicationContext, "Please make sure you enter correct password and username", Toast.LENGTH_SHORT).show()
            }) {
                override fun getBodyContentType(): String {
                    return "application/json"
                }

                @Throws(AuthFailureError::class)
                override fun getBody(): ByteArray {
                    val params2 = HashMap<String, String>()
                    params2.put("Login","your credentials" )
                    params2.put("Password", "your credentials")
                    return JSONObject(params2).toString().toByteArray()
                }

            }
            mRequestQueue!!.add(mStringRequest!!)
        }
