代号在 POST 中发送 JSON BODY

Question

我正在尝试使用 Codename One 发送带有 JSON BODY 的 POST 请求。 这是建立连接并发送消息的代码

    ByteArrayOutputStream bOutput = new ByteArrayOutputStream();
    bOutput.write("{\"Key1\": \"Value1\",\"Key2\": \"Value2\"}".getBytes());  

    try {
        connectAction connReq = new connectAction();

        connReq.setPost(true);
        connReq.addRequestHeader("Authorization", "1234");
        connReq.addRequestHeader("client_id","4321");
        connReq.addRequestHeader("Content-Type","application/json");
        connReq.setUrl("https://myapi.com/test");
        connReq.setHttpMethod("POST");
        connReq.buildRequestBody(bOutput);
        NetworkManager.getInstance().addToQueueAndWait(connReq);
        Map<String,Object> result = new JSONParser().parseJSON(new InputStreamReader(new ByteArrayInputStream(connReq.getResponseData()), "UTF-8"));
        return result; 
    }
    catch(Exception err) {
        System.err.println(err);
        return null;
    }  

这是带有 buildRequestBody Override 的派生类

 public class connectAction extends ConnectionRequest
 {

    connectAction()
    {

    }



    @Override
    public void buildRequestBody(OutputStream os)
    {

    }
}

现在，当我在 public void buildRequestBody(OutputStream os) 放置断点时，我可以看到 'os' 具有值

os = (java.io.ByteArrayOutputStream) {"Key1": "Value1","Key2": "Value2"}

所以我知道它的价值一直走到这一步。

但是，当我启动网络监视器时，仅填充了请求标头并且标头为空。

非常感谢任何帮助。

谢谢

试试下面的代码希望对你有帮助

// convert the object to a JSON document
HashMap hashtable = new HashMap ();
hashtable.put("Key1", "Value1");
hashtable.put("Key2", "Value2");
final String payload = Result.fromContent(hashtable).toString();

protected void buildRequestBody(OutputStream os) throws IOException {
    os.write(payload.getBytes("UTF-8"));
}
