PHP - 登录 userLogin.php 

public class LoginRequestVolley extends StringRequest {
private static final String KEY_EMAIL = "emailAddress";
private static final String KEY_PASSWORD = "password";

private Map<String, String> params;

//FOR LOGIN VOLLEY
public LoginRequestVolley(String emailAddress, String password,
                          Response.Listener<String> listener, Response.ErrorListener errorListener){
    super(Method.POST, ServerScripts.PHP_SCRIPT_PATH + ServerScripts.PHP_LOGIN, listener, errorListener);
    params = new HashMap<>();
    params.put(KEY_EMAIL,emailAddress);
    params.put(KEY_PASSWORD,password);
}}

我进入调试模式并跟踪它，我得到了这个结果 Debug
