我正在使用 HTTPS 在 Android 上获取网页(忽略证书,因为它既是自签名的又是过时的,如此处所示-不要问,它不是我的服务器 :))。
我已经定义了我的
public class MyHttpClient extends DefaultHttpClient {
public MyHttpClient() {
super();
final HttpParams params = getParams();
HttpConnectionParams.setConnectionTimeout(params,
REGISTRATION_TIMEOUT);
HttpConnectionParams.setSoTimeout(params, REGISTRATION_TIMEOUT);
ConnManagerParams.setTimeout(params, REGISTRATION_TIMEOUT);
}
@Override
protected ClientConnectionManager createClientConnectionManager() {
SchemeRegistry registry = new SchemeRegistry();
registry.register(new Scheme("http", PlainSocketFactory
.getSocketFactory(), 80));
registry.register(new Scheme("https", new UnsecureSSLSocketFactory(), 443));
return new SingleClientConnManager(getParams(), registry);
}
}
其中提到的 UnsecureSSLSocketFactory 是基于对上述主题给出的建议。
然后我使用这个类来感染一个页面
public class HTTPHelper {
private final static String TAG = "HTTPHelper";
private final static String CHARSET = "ISO-8859-1";
public static final String USER_AGENT = "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.8) Gecko/20100722 Firefox/3.6.8 (.NET CLR 3.5.30729)";
public static final String ACCEPT_CHARSET = "ISO-8859-1,utf-8;q=0.7,*;q=0.7";
public static final String ACCEPT = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
/**
* Sends an HTTP request
* @param url
* @param post
* @return
*/
public String sendRequest(String url, String post) throws ConnectionException {
MyHttpClient httpclient = new MyHttpClient();
HttpGet httpget = new HttpGet(url);
httpget.addHeader("User-Agent", USER_AGENT);
httpget.addHeader("Accept", ACCEPT);
httpget.addHeader("Accept-Charset", ACCEPT_CHARSET);
HttpResponse response;
try {
response = httpclient.execute(httpget);
} catch (Exception e) {
throw new ConnectionException(e.getMessage());
}
HttpEntity entity = response.getEntity();
try {
pageSource = convertStreamToString(entity.getContent());
} catch (Exception e) {
throw new ConnectionException(e.getMessage());
}
finally {
if (entity != null) {
try {
entity.consumeContent();
} catch (IOException e) {
throw new ConnectionException(e.getMessage());
}
}
}
httpclient.getConnectionManager().shutdown();
return pageSource;
}
/**
* Converts a stream to a string
* @param is
* @return
*/
private static String convertStreamToString(InputStream is)
{
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(is, CHARSET));
StringBuilder stringBuilder = new StringBuilder();
String line = null;
try {
while ((line = reader.readLine()) != null) {
stringBuilder.append(line + "\n");
}
} catch (IOException e) {
Log.d(TAG, "Exception in convertStreamToString", e);
} finally {
try {
is.close();
} catch (IOException e) {}
}
return stringBuilder.toString();
} catch (Exception e) {
throw new Error("Unsupported charset");
}
}
}
我得到的页面在大约一百行后被截断。它在一个精确的点被截断,其中一个“_”(下划线)字符后跟一个“r”字符。它不是页面中的第一个下划线。
我认为这可能是编码问题,所以我尝试了 UTF-8 和 ISO-8859-1,但它仍然被截断。如果我用 Firefox 打开页面,它会报告编码为 ISO-8851-1。
如果您想知道,该网页是https://ricarichiamoci.dsu.pisa.it/ ,它在第 169 行被截断,
function ChangeOffset(NewOffset) {
document.mainForm.last
它应该在哪里
function ChangeOffset(NewOffset) {
document.mainForm.last_record.value = NewOffset;
有谁知道为什么页面被截断?
