新行字符的模糊行为

Question

我正在将一个大字符串上传到web服务.该字符串包含新行字符,写为"\n".数据看起来像是:

 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

以上数据存储在字符串中JsonArrObj.要上传数据/字符串,我使用以下代码:

    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();
    }

字符串已成功上传.我面临的问题是:当字符串被转换为jsonParams,"\n"字符串数据转换"\\n"为结果,在服务器端,它显示一个小方框而不是换行.

当我在NOTEPAD应用程序中打开此字符串时,它会显示小方框.但是当我在WORDPAD应用程序中打开它时,文本显示在一个新行上.据我说,我可能输入了正确的"内容类型"或编码.请为此建议一个解决方案.

JsonArrObj= URLEncoder.encode(JsonArrObj, "utf-8"); 上传自己时出错...

jsonParams- jsonArrObj最终发送的数据如下所示:

05\/06\/2012 04:05:52 PM- DB exists, transferring
data\\n05\/06\/2012 04:32:56 PM- loadUserSpinners,
cursor.getCount()\\u003d2\\n05\/06\/2012 04:32:56 PM- Battery:
50%\\n05\/06\/2012 04:32:56 PM- ITEM SELECTED: 0

嘿，为什么不使用 \n 的 Unicode 值作为以及任何其他造成此问题的字符，例如 U+002FU+006E
