android - 我如何使用 post 方法将数据从 android 发送到我们

Question

我想使用 post 方法将一个简单的数据从 android 设备发送到 asp.net 页面。但我不知道如何从 android 请求网页!!!

asp 页面很好，可以毫无错误地响应数据..但是android应用程序中的问题...

现在我正在使用这段代码，但它不起作用

public void postData() throws ClientProtocolException, IOException, Exception {       
    String key = "https://www.itrack.somee.com/post.aspx?id=10&long=123&lat=123&alt=123";
    //URI  uri=new URI(key);

    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost(key);

    Toast.makeText(this, "here", Toast.LENGTH_LONG).show();
    HttpResponse response = httpclient.execute(httppost);
    Toast.makeText(this,"mm"+response.toString(), Toast.LENGTH_LONG).show();
}

任何帮助......!!

您可以创建 nameValuePairs 的 ArrayList，并使用 setEntity 方法将它们附加到 HttpPost。

ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("Var1",Var1_value));
nameValuePairs.add(new BasicNameValuePair("Var2",Var2_value));
//...ect
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("URL_HERE");       
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
