我正在通过
所以我的问题是,
HttpsUrlConnection
或HttpUrlConnection
(根据设置)从我的Android应用程序连接到Web服务器。到目前为止,我没有遇到任何问题,但是昨天开始我收到了http/https status
响应-1
。即使存在某种错误,Web服务器也不会返回这样的响应。我连接的服务器在出现问题时会返回errorCode
和errorString
。这是我正在使用的代码,但我认为问题不在这里。 public void UseHttpConnection(String url, String charset, String query) {
try {
HttpURLConnection connection = (HttpURLConnection) new URL(url)
.openConnection();
connection.setDoOutput(true);
connection.setRequestMethod("POST");
connection.setRequestProperty("Charset", charset);
connection.setRequestProperty("Content-Type",
"application/x-www-form-urlencoded;charset=" + charset);
OutputStream output = null;
try {
output = connection.getOutputStream();
output.write(query.getBytes(charset));
} catch (IOException e) {
e.printStackTrace();
} finally {
if (output != null)
try {
output.close();
} catch (IOException logOrIgnore) {
}
}
int status = ((HttpURLConnection) connection).getResponseCode();
Log.i("", "Status : " + status);
for (Entry<String, List<String>> header : connection
.getHeaderFields().entrySet()) {
Log.i("Headers",
"Headers : " + header.getKey() + "="
+ header.getValue());
}
InputStream response = new BufferedInputStream(
connection.getInputStream());
int bytesRead = -1;
byte[] buffer = new byte[30 * 1024];
while ((bytesRead = response.read(buffer)) > 0) {
byte[] buffer2 = new byte[bytesRead];
System.arraycopy(buffer, 0, buffer2, 0, bytesRead);
handleDataFromSync(buffer2);
}
connection.disconnect();
} catch (Exception e) {
e.printStackTrace();
}
}
所以我的问题是,
-1
应该代表什么。它是响应某种错误还是其他的什么?
