Android SAX解析器不';无法从HttpSurlConnection.getInputStream()读取流
在我的Android学习过程中还有一个小小的障碍 这是我的密码:Android SAX解析器不';无法从HttpSurlConnection.getInputStream()读取流,android,xml,https,sax,httpurlconnection,Android,Xml,Https,Sax,Httpurlconnection,在我的Android学习过程中还有一个小小的障碍 这是我的密码: HttpsURLConnection con = (HttpsURLConnection) url.openConnection(); byte[] encodedPassword = (user + ":" + pass).getBytes(); String auth = "Basic " + Base64.encodeToString(encodedP
HttpsURLConnection con = (HttpsURLConnection) url.openConnection();
byte[] encodedPassword = (user + ":" + pass).getBytes();
String auth = "Basic " + Base64.encodeToString(encodedPassword, false);
con.setRequestProperty("Authorization", auth);
con.setRequestMethod("GET");
con.setRequestProperty("Content-Type","text/xml");
con.setRequestProperty("Content-Length","" + Integer.toString(urlParameters.getBytes().length));
con.setRequestProperty("Content-Language", "en-US");
con.setRequestProperty("Connection", "close");
con.setUseCaches(false);
con.setDoOutput(true);
con.setDoInput(true);
con.setAllowUserInteraction(true);
DataOutputStream wr = new DataOutputStream(con.getOutputStream());
wr.writeBytes(urlParameters);
wr.flush();
wr.close();
int statusCode = ((HttpURLConnection) con).getResponseCode();
Log.d(TAG, "Response Code = " + statusCode + " Content-Length = " + con.getContentLength());
我得到的响应代码为200,内容长度为2593,因此我知道我可以访问该文件
DataInputStream re = new DataInputStream(con.getInputStream());
SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();
XMLReader xr = sp.getXMLReader();
XMLmyHandler myHandler = new XMLmyHandler();
xr.setContentHandler(myHandler);
xr.parse(new InputSource(re));
该文件格式良好,我将其复制到一个本地不安全的http服务器,它工作得非常好
遗憾的是,当我尝试从安全http执行同样的操作时,它不会起作用
此外,在我的非安全http成功尝试中,我使用HttpClient获取流,而不是此方法
然而,我尝试将HttpClient与安全http一起使用,但失败惨重
我更愿意保留这种方法,如果你知道从我的“con”中提取流的任何方法,并且可以使用SAX,请告诉我!!!感谢您对我的帮助。经过反复试验,我找到了解决此问题的方法 我删除了数据输出流,然后数据输入流工作正常
//DataOutputStream wr = new DataOutputStream(con.getOutputStream());
//wr.writeBytes(urlParameters);
//wr.flush();
//wr.close();
使用以下代码
SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();
XMLReader xr = sp.getXMLReader();
XMLmyHandler myHandler = new XMLmyHandler();
xr.setContentHandler(myHandler);
xr.parse(getInInputStreamFromURL(ur url here.....));
public AndroidHttpClient getClient(String userAgent) {
HttpParams params = new BasicHttpParams();
// Turn off stale checking. Our connections break all the time anyway,
// and it's not worth it to pay the penalty of checking every time.
HttpConnectionParams.setStaleCheckingEnabled(params, false);
// Default connection and socket timeout of 20 seconds. Tweak to taste.
HttpConnectionParams.setConnectionTimeout(params, 20 * 1000);
HttpConnectionParams.setSoTimeout(params, 20 * 1000);
HttpConnectionParams.setSocketBufferSize(params, 8192);
// Don't handle redirects -- return them to the caller. Our code
// often wants to re-POST after a redirect, which we must do ourselves.
HttpClientParams.setRedirecting(params, false);
// Set the specified user agent and register standard protocols.
HttpProtocolParams.setUserAgent(params, userAgent);
SchemeRegistry schemeRegistry = new SchemeRegistry();
schemeRegistry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
HostnameVerifier hostnameVerifier = org.apache.http.conn.ssl.SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER;
SSLSocketFactory socketFactory = SSLSocketFactory.getSocketFactory();
socketFactory.setHostnameVerifier((X509HostnameVerifier) hostnameVerifier);
schemeRegistry.register(new Scheme("https", socketFactory, 443));
ClientConnectionManager manager = new ThreadSafeClientConnManager(params, schemeRegistry);
// We use a factory method to modify superclass initialization
// parameters without the funny call-a-static-method dance.
return new AndroidHttpClient(manager, params);
}
public InputStream getInInputStreamFromURL(String url) {
InputStream inputStream = null;
AndroidHttpClient httpClient = null;
try {
httpClient = getClient("Ramindu");
// Example send http request
HttpGet httpGet = new HttpGet(url);
HttpResponse response = httpClient.execute(httpGet);
inputStream = response.getEntity().getContent();
} catch (Exception e) {
// TODO Auto-generated catch block
Log.e(TAG, "CAUGHT EXCEPTION : " + e);
}
return inputStream;
}
下面是可用的代码,请看一看
快乐编码:)::Pragna失败意味着什么?您能包括您获得的异常或您看到的错误吗?内容长度是否返回0?尝试使用https时的结果是什么?一个异常,一个不同的状态代码,来自服务器的错误输出?嗨,我没有得到任何异常。它只是没有执行任何操作,就像文件长度为0一样
