如何在 url 中使用 JSON 响应

Question

我正在使用 RESTful WebServices 开发一个 android 应用程序

假设， 我正在发送一个 url http 请求为

一些网络服务/数据/访问

并将数据发送为 {"serviceMessageCode":1,"serviceMessageText":"aaaaaa","items":null}

我想用获得的密钥发送另一个请求

somewebService/rest/services/secure/getcategories?apikey=aaaaaa

    int sMC = jsonObj.getInt("serviceMessageCode");

            if (sMC == 1) {
                smt = jsonObj.getString("serviceMessageText");

我可以用吗

somewebService/rest/services/secure/getcategories?apikey=smt

我想我不应该这样做，有人告诉我如何做到这一点..!!

请帮忙……

没有理由不能通过 GET 参数传递某些数据。它实际上取决于后端服务器上的 Rest API。您是否使用任何 REST 客户端或基础 apache http 包类向服务器发出请求？

已编辑：

BufferedReader in = null;

try {
    HttpClient httpclient = new DefaultHttpClient();

    HttpGet request = new HttpGet();
    String uri = String.format("http://somewebService/rest/services/secure/getcategories?apikey=%s", Config.API_KEY); // API_KEY is constant value written somewhere or could you pass it as method argument
    URI website = new URI(uri);
    request.setURI(website);
    HttpResponse response = httpclient.execute(request);
    in = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));

    String line = null;
    StringBuilder builder = new StringBuilder();
    while(null != (line = in.readLine())) {
        builder.append(line);
    }

    in.close();
} catch(Exception e) {
    Log.e("log_tag", "Error in http connection "+e.toString());
}
