在Android截击中使用POST方法将对象作为数据发送？

我正在使用POST方法，并试图使用Android Volley库将对象作为数据发送，以将当前密码更改为新密码，但我无法做到这一点

如何解决这个问题

您还可以使用

StringRequest

将POST

参数作为
JSONObject
发送

试试这个：

    private static final String KEY_Name = "NAME"
    private static final String KEY_MasterID = "MasterID"
    private static final String KEY_USERNAME = "UserName"
    private static final String KEY_OldPASSWORD = "oldPassword"
    private static final String KEY_UserPassword= "UserPassword"

    ..........
    ..................

    JSONObject params = new JSONObject();
    params.put(KEY_Name, Name);
    params.put(KEY_MasterID, master_id);
    params.put(KEY_USERNAME, username);
    params.put(KEY_OldPASSWORD, oldpassword);
    params.put(KEY_UserPassword, newpassword);

    StringRequest stringRequest = new StringRequest(Request.Method.POST, 
            Navigation_URL_SettingRequest, params, 
            new Response.Listener<String>() {
                @Override
                public void onResponse(String response) {
                    Log.i("VOLLEY", response);

                    // VolleyLog.v("Response:%n %s", response.toString(4));

在后端处理JSON对象时，应将StringRequest更改为JSONObjectRequest。因此，您应该将字符串作为JSON对象传递，然后它就可以工作了。
