註冊應用程序代碼不起作用

我正嘗試使用應用程序在在線數據庫中輸入用戶的數據，但數據未插入到數據庫中。 PHP文件是正確的插入數據，但我的應用程序不在這裏是我的register.java文件代碼。 package net.netai.hackt_swg.microbok;註冊應用程序代碼不起作用

請檢查我的更新答案。 – Shailesh

你的用戶的代碼在你的項目感興趣，請準備好Okhttp LIB將數據發送到服務器。當你使用這個代碼時，調用這個方法，然後調用這個方法，但要小心。

public void Register(String nm, String em, String pm) 
{ 
    OkHttpClient client = new OkHttpClient(); 

    RequestBody formBody = new FormBody.Builder() 
        .add("name", nm) 
        .add("email", em) 
        .add("password", pm) 
        .build(); 

    Request request = new Request.Builder() 
       .url("http://hackt_swg.netai.net/app/register.php") 
       .post(formBody) 
       .build(); 

    client.newCall(request).enqueue(new Callback() { 
       @Override 
       public void onFailure(Call call, IOException e) 
       { 
        Log.e(TAG, "Get Api Credentials Request Failed " + call.toString()); 
        e.printStackTrace(); 
       } 

       @Override 
       public void onResponse(Call call, Response response) throws IOException 
       { 
        String responseUser = response.body().string().toString(); 
        Lor.i("[Registration]", ""+responseUser); 
       } 
     }); 
}

仍然無法正常工作並返回null。我不這樣想。 –

謝謝你的code.But現在我以前的代碼工作。再次感謝。 –

我很高興能夠幫到你，讓其他人可以得到幫助。 – Shailesh

我想你錯過了網址。檢查你的網址：http://hackt_swg.netai.net/app/register.php另外我建議使用改造。這是網絡服務的最佳方式

但仍然不起作用 –

請問您可以編寫php代碼嗎？ –

我編輯我的帖子，你可以看到它 –
