推荐答案

我使用愤怒的IP扫描程序扫描路由器中的主机，获取路由器分配给我的机器的IP地址，然后将其替换为URL； http://xxx.xxx.x.xxx/cropkeeper/spinner/soilCategory.php

I used Angry IP scanner to scan my router for hosts, got the IP address the router assigns to my machine , and replaced it in the URL thus ; http://xxx.xxx.x.xxx/cropkeeper/spinner/soilCategory.php

这是我的尝试

`try {
        // connectivity to database
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost("http://xxx.xxx.x.xxx/cropkeeper/spinner/soilCategory.php");
        HttpResponse response = httpclient.execute(httppost);
        HttpEntity entity = response.getEntity();
        is = entity.getContent();
    }
    catch(Exception e) {
        Log.e("Fail 3", e.toString());
        Toast.makeText(getApplicationContext(), "Invalid IP Address", Toast.LENGTH_LONG).show();
        finish();
    }`

其中xxx.xxx.x.xxx是我的IP地址.
