使用下面的Java代碼平臺方法在谷歌的AppEngine JAVA創建一個HTTP請求SDK1.9.50
URL urlObj = new URL(urlStr);
HttpURLConnection httpConn = (HttpURLConnection)urlObj.openConnection();
httpConn.setDoOutput(true);
httpConn.setRequestMethod("GET");
int statusCode = httpConn.getResponseCode();
if (statusCode != HttpURLConnection.HTTP_OK) {
logger.severe("Error in opening url:" + urlStr);
return;
}
bufferReader = new BufferedReader (new InputStreamReader(httpConn.getInputStream(), "UTF-8"));
String line = null;
while ((line = bufferReader.readLine()) != null) {
logger.info(line);
}
它在谷歌應用程序引擎運行工作在AppEngine上SDK我想提出一個URL請求沒有任何問題缺少警告49年9月1日。 但是,當我升級到50年9月1日將其返回下面的警告
[INFO] 3月 11, 2017 12:04:51 下午 com.google.appengine.repackaged.com.google.protobuf.UnsafeUtil supportsUnsafeByteBufferOperations

什麼樣的行動,我需要採取或只是忽略它? Thx
在版本49和50中發生在我身上。它顯示404錯誤沒有在響應中找到。 – flashsnake
