我正在使用JSON的Web服務應用程序。 在執行任務時,我通過點擊URL直接獲取JSOn響應成功。json解析黑莓手機?
現在我有一個任務請求一個請求參數。
enter code here
private void callJSON_Webservice(String method,String paraLastModifiedDate) {
HttpConnection c=null;
InputStream is = null;
String feedURL = Constants.feedURL;
int rc;
try{
JSONObject postObject = new JSONObject();
postObject.put("CheckLatestDataDate",method);
postObject.put("LastModifiedDate", paraLastModifiedDate);
//c = new HttpConnectionFactory().getHttpConnection(feedURL);
c = (HttpConnection)Connector.open(feedURL + ConnectionManager.getConnectionString());
// Set the request method and headers
c.setRequestMethod(HttpConnection.GET);
c.setRequestProperty("Content-Type", "application/json;charset=UTF-8");
c.setRequestProperty("Content-Length", "" + (postObject.toString().length() - 2));
//c.setRequestProperty("method", HttpConnection.GET);
// Getting the response code will open the connection,
// send the request, and read the HTTP response headers.
// The headers are stored until requested.
rc = c.getResponseCode();
if (rc != HttpConnection.HTTP_OK){
throw new IOException("HTTP response code: " + rc);
}
is = c.openInputStream();
String json = StringUtils.convertStreamToString(is);
object = new JSONObject(json);
}catch (Exception e) {
System.out.println(e+"call webservice exception");
}
}
有了這段代碼,我得到了EOF異常。我需要儘快完成這項小任務。請幫幫我...! Thanx提前
Rupak,我在JSON和XML發送請求的參數很困惑,我已經通過發佈請求參數來執行XML解析,但無法用JSON完成。請從核心提供一些示例代碼或片段來指導我。 –

thanz很多Rupak,這真的是一個很大的幫助...!我完成了這項任務。並獲得我的數據。向服務器發送請求的步驟與xml解析的步驟相似,只需要處理我們將以JSON形式獲得的響應。在我的腦海中爲整個人生而設置。感謝社區。 –
