如何 post json格式的数据,并附加http头,接受返回数据,请看下面的代码:

view plaincopy to clipboardprint?private void HttpPostData() {
try {
HttpClient httpclient = new DefaultHttpClient();
String uri = "http://www.yourweb.com";
HttpPost httppost = new HttpPost(uri);
//添加http头信息
httppost.addHeader("Authorization", "your token"); //认证token
httppost.addHeader("Content-Type", "application/json");
httppost.addHeader("User-Agent", "imgfornote");
//http post的json数据格式: {"name": "your name","parentId": "id_of_parent"}
JSONObject obj = new JSONObject();
obj.put("name", "your name");
obj.put("parentId", "your parentid");
httppost.setEntity(new StringEntity(obj.toString()));
HttpResponse response;
response = httpclient.execute(httppost);
//检验状态码,如果成功接收数据
int code = response.getStatusLine().getStatusCode();
if (code == 200) {
String rev = EntityUtils.toString(response.getEntity());//返回json格式: {"id": "27JpL~j4vsL0LX00E00005","version": "abc"}
obj = new JSONObject(rev);
String id = obj.getString("id");
String version = obj.getString("version");
}
} catch (ClientProtocolException e) {
} catch (IOException e) {
} catch (Exception e) {
}
}
private void HttpPostData() {
try {
HttpClient httpclient = new DefaultHttpClient();
String uri = "http://www.yourweb.com";
HttpPost httppost = new HttpPost(uri);
//添加http头信息
httppost.addHeader("Authorization", "your token"); //认证token
httppost.addHeader("Content-Type", "application/json");
httppost.addHeader("User-Agent", "imgfornote");
//http post的json数据格式: {"name": "your name","parentId": "id_of_parent"}
JSONObject obj = new JSONObject();
obj.put("name", "your name");
obj.put("parentId", "your parentid");
httppost.setEntity(new StringEntity(obj.toString()));
HttpResponse response;
response = httpclient.execute(httppost);
//检验状态码,如果成功接收数据
int code = response.getStatusLine().getStatusCode();
if (code == 200) {
String rev = EntityUtils.toString(response.getEntity());//返回json格式: {"id": "27JpL~j4vsL0LX00E00005","version": "abc"}
obj = new JSONObject(rev);
String id = obj.getString("id");
String version = obj.getString("version");
}
} catch (ClientProtocolException e) {
} catch (IOException e) {
} catch (Exception e) {
}
}主要用到的类有:org.apache.http.client.HttpClient 、org.apache.http.client.methods.HttpPost 和 org.json.JSONObject
