我想创建注册页面。我在SignFragment中添加凌空。我无法连接Json。我给出了带或不带参数的注册数据。请帮我。 这是我的代码。
SignFragment.java
public class SignFragment extends Fragment {
private EditText editTextFname, editTextLname, editTextMnumber, editTextEmail, editTextPass, editTextCpass;
private String firstName, lastname, mobileNumber, emailId, password, cPassword;
private Button buttonRegister;
public SignUpFragment() {
// Required empty public constructor
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view= inflater.inflate(R.layout.fragment_sign_up, container, false);
editTextFname=(EditText) view.findViewById(R.id.f_name);
editTextLname=(EditText) view.findViewById(R.id.l_name);
editTextMnumber=(EditText) view.findViewById(R.id.user_mobile);
editTextEmail=(EditText) view.findViewById(R.id.user_email);
editTextPass=(EditText) view.findViewById(R.id.user_pass);
editTextCpass=(EditText) view.findViewById(R.id.user_cpass);
buttonRegister=(Button)view.findViewById(R.id.register_btn);
buttonRegister.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
userRegister();
}
});
return view;
}
private void userRegister() {
String url = "...../api/Signup";
StringRequest stringRequest = new StringRequest(Request.Method.POST, url,
new Response.Listener<String>() {
@Override
public void onResponse(String response) {
try {
JSONObject jObj = new JSONObject(response);
JSONObject user = jObj.getJSONObject("data");
String msgs = user.getString("message");
Toast.makeText(getContext(), "" + msgs, Toast.LENGTH_SHORT).show();
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
}
}) {
@Override
protected Map<String, String> getParams() {
String fname = editTextFname.getText().toString().trim();
String lname = editTextLname.getText().toString().trim();
String mnumber = editTextMnumber.getText().toString().trim();
String email = editTextEmail.getText().toString().trim();
String pwd = editTextPass.getText().toString().trim();
String confirmpwd = editTextCpass.getText().toString().trim();
Map<String, String> params = new HashMap<>();
params.put("fname", fname);
params.put("lname", lname);
params.put("mnumber", mnumber);
params.put("message", email);
params.put("name", pwd);
params.put("name", confirmpwd);
return params;
}
};
stringRequest.setRetryPolicy(new DefaultRetryPolicy(
20000,
DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT
));
RequestQueue requestQueue = Volley.newRequestQueue(getContext());
requestQueue.add(stringRequest);
}
}
这是我的Json Signdata
url： - “... / api / Signup”
{
"code": 2,
"msg": "first name is required\nlast name is required\ncontact phone is required\n",
"details": "",
"request": "[]"
}
这是我带参数的Json Signdata。
url： - “.... / api / Signup？first_name = ram＆amp; last_name = verma＆amp; email_address=ram@gmail.com& password = 987＆amp; cpassword = 987＆amp; contact_phone = 2222222”
{
"code": 2,
"msg": "Sorry but your mobile number is already exist in our records",
"details": "",
"request": "{\"first_name\":\"ram\",\"last_name\":\"verma\",\"email_address\":\"ram@gmail.com\",\"password\":\"987\",\"cpassword\":\"987\",\"contact_phone\":\"2222222\"}"
}
