大きな文字列を Web サービスにアップロードしています。文字列には、「\n」と書かれた改行文字が含まれています。データは次のようになります。
05/06/2012 11:35:43 AM- DB exists, transferring data\n05/06/2012
11:48:20 AM- loadUserSpinners, cursor.getCount()=2\n05/06/2012
11:48:20 AM- Battery: 50%\n05/06/2012 11:48:20 AM- ITEM SELECTED: 0
the above data is stored in string JsonArrObj
. To upload the data/string, i am using the following code:
HttpParams httpParameters = new BasicHttpParams();
int timeoutConnection = 360000; //6 minutes
HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection);
int timeoutSocket = 420000; //7 minutes
HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);
HttpClient httpClient = new DefaultHttpClient(httpParameters);
JSONArray jsonParams = new JSONArray();
Object[] params={IPAddress,Database,DbName,DbPassword,JsonArrObj};
for (int i = 0; i < params.length; i++) {
jsonParams.put(params[i]);
}
JSONObject jsonRequest = new JSONObject();
jsonRequest.put("id", Id);
jsonRequest.put("method", FunctionName);
jsonRequest.put("params", jsonParams);
JSONEntity entity = new JSONEntity(jsonRequest);
entity.setContentType("application/json; charset=utf-8");
HttpPost request = new HttpPost(URL);
request.setEntity(entity);
HttpResponse response = httpClient.execute(request);
StatusLine statusLine = response.getStatusLine();
int statusCode = statusLine.getStatusCode();
if (statusCode == 200) {
HttpEntity httpEntity = response.getEntity();
InputStream content = httpEntity.getContent();
BufferedReader reader = new BufferedReader(
new InputStreamReader(content,"iso-8859-1"),8);
String line;
while ((line = reader.readLine()) != null) {
builder.append(line);
LogE("result line: "+line);
String str=convertString(line);
parseJson(str);
}
content.close();
}
The string is uploaded successfully. The problem I am facing is: while string is being converted to jsonParams
, the "\n"
in the string data gets converted to "\\n"
as a result, on the server side, it shows a small box in stead of new line.
When I open this string in NOTEPAD application, it displays small boxes. But when I open it in WORDPAD app, text is displayed on a new line. According to me, I might have entered in-correct "content-type" or encoding. Please suggest a solution for the same.
JsonArrObj= URLEncoder.encode(JsonArrObj, "utf-8");
gave error while uploading itself...
The data which is sent in the jsonParams- jsonArrObj
finally looks like:
