我发送json请求代码给出错误是否有任何方法如何 发送带有authentication.this代码的json请求给出错误 在filenotfound＆＃34; http://api.seatseller.travel/blockTicket＆＃34;
// st = json对象
StringBuilder sb = new StringBuilder();
JSONObject jsonParam = st;//JSON
HttpURLConnection request=null;
OAuthConsumer consumer = new DefaultOAuthConsumer("tOzL5hTkSz9KiA2RIAECW4g7Uq","cj8HLPmBKnRAsffLe5qpQIZ9Y");
consumer.setTokenWithSecret(null, null); //i pass token as access token as a null as my server dont need it.
URL url = new URL("http://api.seatseller.travel/blockTicket");
request = (HttpURLConnection) url.openConnection();
request.setDoOutput(true);
request.setRequestMethod("GET");
request.setUseCaches(false);
request.setConnectTimeout(10000);
request.setReadTimeout(10000);
request.setRequestProperty("Content-Type","application/json");
request.setRequestProperty("Host", "android.schoolportal.gr");
consumer.sign(request);
request.connect();
OutputStreamWriter out = new OutputStreamWriter(request.getOutputStream());
out.write(jsonParam.toString());
out.close();
int HttpResult =request.getResponseCode();
if(HttpResult ==HttpURLConnection.HTTP_OK){
BufferedReader br = new BufferedReader(new InputStreamReader(
request.getInputStream(),"utf-8"));
String line = null;
while ((line = br.readLine()) != null) {
sb.append(line + "\n");
}
br.close();
System.out.println(""+sb.toString());
}else{
System.out.println(request.getResponseMessage());
}
} catch (MalformedURLException e) {
e.printStackTrace();
}
catch (IOException e) {
e.printStackTrace();
}
catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();

public class JSONParser {
static InputStream is = null;
static JSONObject jObj = null;
static String json = "";
public JSONParser() {
}
public JSONObject makeHttpRequest(String url, String method,
List<NameValuePair> params) {
try {
if(method == "POST"){
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
httpPost.setEntity(new UrlEncodedFormEntity(params));
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
}else if(method == "GET"){
DefaultHttpClient httpClient = new DefaultHttpClient();
String paramString = URLEncodedUtils.format(params, "utf-8");
url += "?" + paramString;
HttpGet httpGet = new HttpGet(url);
HttpResponse httpResponse = httpClient.execute(httpGet);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
}
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(
is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
json = sb.toString();
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
}
try {
jObj = new JSONObject(json);
} catch (JSONException e) {
Log.e("JSON Parser", "Error parsing data " + e.toString());
}
return jObj;
}
}
然后创建AsyncTask类以将数据上传到服务器。然后添加此代码。
JSONParser jsonParser = new JSONParser();
@Override
protected String doInBackground(String... strings) {
String message="";
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("value1", value1));
JSONObject json = jsonParser.makeHttpRequest(SERVER_URL,
"POST", params);
try {
message=json.getString("message");
Log.e("msg",message);
}catch (JSONException e) {
e.printStackTrace();
}
return message ;
}
value1发送到服务器。
