android - 将 Curl Post 与请求队列 Kotlin Android 相结合

Question

以下适用于 REST api，但是我现在正试图在 Android Kotlin 中实现相同的效果

curl -X POST \
    -H 'content-type:application/json' \
    -d '{"userid":"testid","first_name":"test_first_name"}' \
    http://localhost:5000/users

我尝试在 kotlin 中调用相同的 curl：

    fun submit_new_user(view: View) {
        val textView = findViewById<TextView>(R.id.textView111)
        // ...
        // Instantiate the RequestQueue.
        val queue = Volley.newRequestQueue(this)
        //build the curl
        val requestBody = "userid=testid" + "&first_name=test_first_name"
        // Request a string response from the provided URL.
        val url = "http://localhost:5000/users?" + requestBody
        val stringRequest = StringRequest(
            Request.Method.POST, url,
            Response.Listener<String> { response ->
                // Display the first 500 characters of the response string.
                textView.text = "Response is: ${response.substring(0, 20)}"
            },
            Response.ErrorListener { textView.text = "That didn't work!" } )
        // Add the request to the RequestQueue.
        queue.add(stringRequest)
    }

任何人都可以解释一些安全问题

通过使用另一个问题的这个解决方案让它工作，

        val textView = findViewById<TextView>(R.id.textView111)
        val url = "http://localhost:5000/users"
        val sr: StringRequest = object : StringRequest(
            Method.POST, url,
            Response.Listener { response -> textView.text = "Response is: ${response.substring(0, 20)}" },
            Response.ErrorListener { error -> textView.text = "That didn't work!"  }) {
            @Throws(AuthFailureError::class)
            override fun getBody(): ByteArray {
                val params2 = HashMap<String?, String?>()
                params2["userid"] = "testid"
                params2["email_address"] = "[e-mail]"
                return JSONObject(params2 as Map<*, *>).toString().toByteArray()
            }
            override fun getBodyContentType(): String {
                return "application/json"
            }
        }
        // Add the request to the RequestQueue.
        Volley.newRequestQueue(this).add(sr)
