如何将给定的json包装成字符串并通过android中的Http put请求将其发送到服务器?
这就是我的 json 的样子。
{
"version": "1.0.0",
"datastreams": [
{
"id": "example",
"current_value": "333"
},
{
"id": "key",
"current_value": "value"
},
{
"id": "datastream",
"current_value": "1337"
}
]
}
以上是我的 json 数组。
以下是我编写代码的方式,但是它不起作用
protected String doInBackground(Void... params) {
String text = null;
try {
JSONObject child1 = new JSONObject();
try{
child1.put("id", "LED");
child1.put("current_value", "0");
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
JSONArray jsonArray = new JSONArray();
jsonArray.put(child1);
JSONObject datastreams = new JSONObject();
datastreams.put("datastreams", jsonArray);
JSONObject version = new JSONObject();
version.put("version", "1.0.0");
version.put("version", datastreams);
HttpClient httpClient = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();
HttpPut put = new HttpPut("url");
put.addHeader("X-Apikey","");
StringEntity se = new StringEntity( version.toString());
se.setContentType(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
put.addHeader("Accept", "application/json");
put.addHeader("Content-type", "application/json");
put.setEntity(se);
try{
HttpResponse response = httpClient.execute(put, localContext);
HttpEntity entity = response.getEntity();
text = getASCIIContentFromEntity(entity);
}
catch (Exception e) {
return e.getLocalizedMessage();
}
}catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (UnsupportedEncodingException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
return text;
}
请帮忙
