Question

我正在尝试将数据从Android智能手机发送到使用jersey库在java中创建的一个安静的网络服务。

我看到了如何做到以下答案：

public void postData() {
    // Create a new HttpClient and Post Header
    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost("http://www.yoursite.com/script.php");

    try {
        // Add your data
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
        nameValuePairs.add(new BasicNameValuePair("id", "12345"));
        nameValuePairs.add(new BasicNameValuePair("stringdata", "Hi"));
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

        // Execute HTTP Post Request
        HttpResponse response = httpclient.execute(httppost);

    } catch (ClientProtocolException e) {
        // TODO Auto-generated catch block
    } catch (IOException e) {
        // TODO Auto-generated catch block
    }
}

虽然这似乎是对的，但我对nameValuePairs变量有疑问。特别是在这一部分：

 nameValuePairs.add(new BasicNameValuePair("id", "12345"));

如果我的网络服务具有以下签名：

@POST
@Path("/post/location")
@Consumes(MediaType.APPLICATION_JSON)
public Response createLocation(Loc location)

"id"变量中的nameValuePairs部分是什么，它是位置还是Loc？。

试试这个

    //
    String url = 'url_to_you_server_api.dev/postservice'

    HttpClient client = new DefaultHttpClient();

    HttpPost request = new HttpPost(url);

    JSONObject params = new JSONObject();

    params.put("id","id");
    params.put("hi","hi");

    StringEntity jsonEntity = new StringEntity( params.toString() );

    HttpPost request = new HttpPost(url);

    request.addHeader("Content-Type","application/json");

    request.setEntity(jsonEntity);

    response = client.execute(request);

如果你服务接收一个实体它可能是一个json或者不仅仅是与表单数据相对应的键值参数。
