php - Android Kotlin Volley Post String具有多个变量

Question

我想使用POST方法将用户名和密码字符串发布到php页面，但找不到解决方案。因此，我尝试使用JSONRequest方法，但它始终为我提供Response.ErrorListener的结果。请帮助解决。

StringRequest的代码:

UserNamePassword =“名称= aaa＆密码= bbb”

val queue = Volley.newRequestQueue(this)

val stringRequest = StringRequest(Request.Method.POST, url,
        Response.Listener<String> { response ->
        // Display the first 500 characters of the response string.
           println(response.toString())
        }, Response.ErrorListener { println("That didn't work!") })

// Add the request to the RequestQueue.
queue.add(stringRequest)

JSONRequest的代码:

val jsonobj = JSONObject()

jsonobj.put("Name", "aaa")
jsonobj.put("Password", "bbb")

val que = Volley.newRequestQueue(this)
val req = JsonObjectRequest(Request.Method.POST,url,jsonobj,
            Response.Listener {
                response ->
                //println(response["msg"].toString())
                println("oooooooooooooookkkkkkkkkkkkkkkkkk")
            }, Response.ErrorListener {
                println("Error rrrrrrrrrrrrrrr")
            }
        )
que.add(req)

Answer 1

尝试一下

...
}, Response.ErrorListener { error: VolleyError ->
    println("Error $error.message")
}
...

正如您所说，我们收到了以下错误消息

06-07 20:46:17.317 10064-10064/com.gph.radiobutton I/Choreographer: Skipped 47 frames!  The application may be doing too much work on its main thread.

然后我们可以看到问题是另一个问题，例如，您的Web服务上确实发生了错误，并且 您没有将它们作为有效json再次发送给应用程序。
