我正在构建一个模拟器，以将JSON数据发布到正在运行的服务中。

JSON应该如下所示：

{"sensor":

{"id":"SENSOR1","name":"SENSOR","type":"Temperature","value":100.12,"lastDateValue":"\/Date(1382459367723)\/"}

}

我在Chrome中使用“高级REST客户端”进行了尝试，效果很好。ServiceStack Web服务会正确解析日期获取。

因此，关键是编写一个传感器模拟器，将这样的数据发布到Web服务。

我用Java创建了它，因此可以在树莓派上运行它。

这是代码：

public static void main(String[] args) {

String url = "http://localhost:63003/api/sensors";

String sensorname = "Simulated sensor";

int currentTemp = 10;

String dateString = "\\" + "/Date(" + System.currentTimeMillis() + ")\\" + "/";

System.out.println(dateString);

System.out.println("I'm going to post some data to: " + url);

//Creating the JSON Object

JSONObject data = new JSONObject();

data.put("id", sensorname);

data.put("name", sensorname);

data.put("type", "Temperature");

data.put("value", currentTemp);

data.put("lastDateValue", dateString);

JSONObject sensor = new JSONObject().put("sensor", data);

//Print out the data to be sent

StringWriter out = new StringWriter();

sensor.write(out);

String jsonText = out.toString();

System.out.print(jsonText);

//Sending the object

HttpClient c = new DefaultHttpClient();

HttpPost p = new HttpPost(url);

p.setEntity(new StringEntity(sensor.toString(), ContentType.create("application/json")));

try {

HttpResponse r = c.execute(p);

} catch (Exception e) {

e.printStackTrace();

}

}

该程序的输出如下：

\/Date(1382459367723)\/

I'm going to post some data to: http://localhost:63003/api/sensors

{"sensor":{"lastDateValue":"\\/Date(1382459367723)\\/","id":"Simulated sensor","name":"Simulated sensor","value":10,"type":"Temperature"}}

这里的问题是JSONObject字符串仍然包含这些转义字符。但是，当我在开头打印字符串时，它不包含转义字符。有什么办法摆脱这些？我的服务无法解析这些。

这是我与chrome的其余客户端一起发送的示例：

{"sensor":{"id":"I too, am a sensor!","name":"Willy","type":"Temperature","value":100.12,"lastDateValue":"\/Date(1382459367723)\/"}}
