凌空GSON - 发送使用JSONObjectRequest POST请求 [英] Volley and Gson -Sending a POST request using JSONObjectRequest
问题描述
我是新来的，我不很好说英语，但我尽我所能来解释我。
我有一些问题与POST请求。这是我的code：
I'm new here and I don't very well speak English, but I do my best to explain me. I have some problems with the Post request. This is my code:
private void makeRequest() {
String url = "http://diegocardenas.netau.net/comprobar_usuario.php";
JsonObjectRequest request1=new JsonObjectRequest(Method.POST, url, new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
onConnectionFinished();
Usuario usuario = new Gson().fromJson(response.toString(), Usuario.class);
if (usuario != null) {
Log.i("App1", "Nombre:" + usuario.getNombre() + " Correo: " + usuario.getCorreo());
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
onConnectionFailed(error.toString());
Log.i("App1", error.getMessage());
}
}){
@Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String,String> params=new HashMap<>();
params.put("correo","daniel@gmail.com");
params.put("clave","daniel");
return params;
}
};
addToQueue(request1);
}
这是Usuario类：
This is the Usuario class:
public class Usuario {
private int cod_usuario, contador, estado;
private String nombre, correo;
public Usuario() {
}
public int getCod_usuario() {
return cod_usuario;
}
public void setCod_usuario(int cod_usuario) {
this.cod_usuario = cod_usuario;
}
public int getContador() {
return contador;
}
public void setContador(int contador) {
this.contador = contador;
}
public String getNombre() {
return nombre;
}
public void setNombre(String nombre) {
this.nombre = nombre;
}
public String getCorreo() {
return correo;
}
public void setCorreo(String correo) {
this.correo = correo;
}
public int getEstado() {
return estado;
}
public void setEstado(int estado) {
this.estado = estado;
}
}

的
字段：cod_usuario诠释，农布雷VARCHAR，则邮报varchar，将釜VARCHAR，则埃斯塔布尔，康塔多诠释
the table: Usuario fields: cod_usuario Int, nombre Varchar, correo Varchar, clave Varchar, estado Boolean, contador Int

我证明使用GET的连接，我返回的数据，但使用POST失败所有的xD时
我认为这个问题是方法getParams ...
I prove the connection using GET and I returned the data, but when using POST failure all xD I think the problem is the method getparams...
请帮助！！！！
推荐答案
如果您认为问题是getParams，然后用排枪，你不必使用getParams，它知道如何处理的JSONObject所以你可以使用
if you think the problem is with getParams, then with Volley you don't have to use the getParams, it knows how to deal with JSONObject so you can use:
String someurl = URL;
Map<String, Object> jsonParams = new HashMap<>();
jsonParams.put("someparam", getSomeParam());
JsonObjectRequest request = new JsonObjectRequest(Request.Method.POST, someurl, new JSONObject(jsonParams),
new Response.Listener<JSONObject>()
{
@Override
public void onResponse(JSONObject response)
{
Log.d(TAG + ": ", "Response: " + response.toString());
//do other stuff
}
},
new Response.ErrorListener()
{
@Override
public void onErrorResponse(VolleyError error)
{
if (null != error.networkResponse)
{
Log.d(TAG + ": ", "Error Response code: " + error.networkResponse.statusCode);
}
}
});
requestQueue.add(request);
另外 - 确保在Usuario类中的变量名匹配您取回您的JSON的名字，如果它不匹配Usuario变量将默认为NULL
Also - make sure the variable names in Usuario class match the names you get back in your Json, if it doesn't match the variable in Usuario will be NULL by default.
