我想通过获得内容大小request.getContentLength()
在服务器端JSP页面。 但request.getContentLength()总是返回-1,我不为什么?
Android的代码片段:
URL uri = new URL(actionUrl);
HttpURLConnection conn = (HttpURLConnection) uri.openConnection();
//conn.setChunkedStreamingMode(100);
conn.setConnectTimeout(setTimeOut>0?setTimeOut:timeoutConnection);
conn.setReadTimeout(setTimeOut>0?setTimeOut:timeoutConnection);
conn.setDoInput(true);
conn.setDoOutput(true);
conn.setUseCaches(false);
conn.setRequestMethod("POST");
conn.setRequestProperty("Connection", "keep-alive");
//conn.setRequestProperty("content-length", "10");
//conn.addRequestProperty("content-length", "20");
conn.setFixedLengthStreamingMode(30);
conn.setRequestProperty("Charsert", ENCODING);
conn.setRequestProperty("Content-Type", "multipart/form-data"
+ ";boundary=" + java.util.UUID.randomUUID().toString());
conn.connect();
