Volley-AuthFailureError

Question

我想在用戶在android設備上填充文本框時，在phpMyAdmin數據庫中插入新用戶。爲此，我寫的PHP代碼，我測試它在POSTMAN和它的作品，但是當我在Android真實設備上測試時，我得到了AuthFailureError！在POSTMAN中，我將授權設置爲「無驗證」。 這是我在android工作室的代碼：

public class Registration extends AppCompatActivity { 
private EditText name,surname,email,password,adress; 
    private Button btnLog; 
    private RequestQueue requestQueue; 
    private static final String URL="http://192.168.*.*/Log/LogUser.php"; 
    private StringRequest request; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_registruj_se); 
     name=(EditText) findViewById(R.id.txtName); 
     surname=(EditText)findViewById(R.id.txtSurname); 
     email=(EditText)findViewById(R.id.txtEmail); 
     password=(EditText)findViewById(R.id.txtPassword); 
     adress=(EditText)findViewById(R.id.txtAdress); 
     btnLog=(Button)findViewById(R.id.btnLog); 
     requestQueue= Volley.newRequestQueue(this); 
     btnLog.setOnClickListener(new View.OnClickListener(){ 

      @Override 
      public void onClick(View v) { 
       request=new StringRequest(Request.Method.POST,URL,new Response.Listener<String>(){ 
        @Override 
        public void onResponse(String response) { 
         try 
         { 
          JSONObject jsonObject=new JSONObject(response); 
         if(jsonObject.names().get(0).equals("success")){ 
          Toast.makeText(getApplicationContext(),"success:"+jsonObject.getString("success"),Toast.LENGTH_SHORT).show(); 

          startActivity(new Intent(getApplicationContext(),Welcome.class)); 
         }else{ Toast.makeText(getApplicationContext(),"error:"+jsonObject.getString("error"),Toast.LENGTH_SHORT).show();} 

         } 

         catch (JSONException e){e.printStackTrace();} 
        } 
       },new Response.ErrorListener(){ 
        @Override 
        public void onErrorResponse(VolleyError error) { 


         if (error instanceof NetworkError) { 
          Toast.makeText(getApplicationContext(),"Cannot connect to Internet...Please check your connection!",Toast.LENGTH_SHORT).show(); 
         } else if (error instanceof ServerError) { 
          Toast.makeText(getApplicationContext(),"The server could not be found. Please try again after some time!!",Toast.LENGTH_SHORT).show(); 

         } else if (error instanceof AuthFailureError) { 
          Toast.makeText(getApplicationContext(),"AuthFailureError",Toast.LENGTH_SHORT).show(); 
         } else if (error instanceof ParseError) { 
          Toast.makeText(getApplicationContext(),"Parsing error! Please try again after some time!!",Toast.LENGTH_SHORT).show(); 

         } else if (error instanceof NoConnectionError) { 
          Toast.makeText(getApplicationContext(),"NoConnectionError",Toast.LENGTH_SHORT).show(); 
         } else if (error instanceof TimeoutError) { 
          Toast.makeText(getApplicationContext(),"Connection TimeOut! Please check your internet connection.",Toast.LENGTH_SHORT).show(); 

         } 
        } 
       }) 
       { 

        @Override 
        protected Map<String, String> getParams() throws AuthFailureError { 
         HashMap<String,String>hashMap=new HashMap<String, String>(); 
         hashMap.put("name",name.getText().toString()); 
         hashMap.put("surname",surname.getText().toString()); 
         hashMap.put("email",email.getText().toString()); 
         hashMap.put("password",password.getText().toString()); 
         hashMap.put("adress",adress.getText().toString()); 
         return hashMap; 
        } 

        @Override 
        public Map<String, String> getHeaders() throws AuthFailureError { 
         HashMap<String, String> headers = new HashMap<String, String>(); 
         // do not add anything here 
         return headers; 
        } 
        @Override 
        public String getBodyContentType() { 
         return "application/json"; 
        } 

       }; 
       requestQueue.add(request); 
      } 
     }); 

我很感激任何幫助！

試試這個：

在getBodyContentType()方法返回"application/x-www-form-urlencoded"代替"application/json"

代碼

@Override 
public String getBodyContentType() { 
     return "application/x-www-form-urlencoded"; 
}
