我正在尝试创建一个涉及登录的应用程序。但是我在注册时遇到了问题。
我尝试更改php，但是遇到了同样的问题。
private void registerUser() {
displayLoader();
JSONObject request = new JSONObject();
try {
request.put(KEY_USERNAME, username);
request.put(KEY_PASSWORD, password);
request.put(KEY_EMAIL, email);
} catch (JSONException e) {
e.printStackTrace();
}
JsonObjectRequest jsArrayRequest = new JsonObjectRequest
(Request.Method.POST, register_url, request, new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
pDialog.dismiss();
try {
if (response.getInt(KEY_STATUS) == 0) {
session.loginUser(username,email);
loadDashboard();
}else if(response.getInt(KEY_STATUS) == 1){
etUsername.setError("Usuario já usado");
etUsername.requestFocus();
}else if(response.getInt(KEY_STATUS) == 3){
etEmail.setError("Email já usado");
etEmail.requestFocus();
} else{
Toast.makeText(getApplicationContext(),
response.getString(KEY_MESSAGE), Toast.LENGTH_SHORT).show();
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
pDialog.dismiss();
Toast.makeText(getApplicationContext(), error.getMessage(), Toast.LENGTH_SHORT).show();
}
});
MySingleton.getInstance(this).addToRequestQueue(jsArrayRequest);
}
public class MySingleton {
private static MySingleton mInstance;
private RequestQueue mRequestQueue;
private static Context mCtx;
private MySingleton(Context context) {
mCtx = context;
mRequestQueue = getRequestQueue();
}
public static synchronized MySingleton getInstance(Context context) {
if (mInstance == null) {
mInstance = new MySingleton(context);
}
return mInstance;
}
private RequestQueue getRequestQueue() {
if (mRequestQueue == null) {
mRequestQueue = Volley.newRequestQueue(mCtx.getApplicationContext());
}
return mRequestQueue;
}
public <T> void addToRequestQueue(Request<T> req) {
getRequestQueue().add(req);
}
}
<?php
$response = array();

$inputJSON = file_get_contents('http://teste-app-lhama.epizy.com/controle/registrar.php');

else{

$response["message"] = "Email j? existe";
}
}
else{
$response["status"] = 1;
$response["message"] = "Usuario j? existe";
}
}
else{
$response["status"] = 2;
$response["message"] = "Falta de parametro obrigatorios";
}
echo json_encode($response);
?>
function userExists($username){

奇怪的是，当我在浏览器中输入url：“ http://teste-app-lhama.epizy.com/controle/registrar.php”时，我得到以下结果：“ {” status”：2，“ message”：“ Falta de parametro obrigatorios”（缺少强制性）参数）}“ 可能结果是返回正确的值，对吧？
我相信问题出在我的php中，如果“ if（isset（$ input ['username']）&& isset（$ input ['password']）&& isset（$ input ['email']）） “
我正在互联网上阅读，我发现有人说此错误可能是由主机引起的。如果是这样，我该怎么办？
答案 0 :(得分：1)
不要忘记将标头内容类型设置为json，因此响应应视为json而不是string :)：
<?PHP
$data = /** whatever you're serializing **/;
header('Content-Type: application/json');
echo json_encode($data);
不要这样做：
echo "Email existente";
它是字符串，而不是json。

错误在这里：
$inputJSON = file_get_contents('http://teste-app-lhama.epizy.com/controle/registrar.php');
应为：
$inputJSON = file_get_contents('php://input');
