【问题描述】:
所以我使用了很好的 HttpClient 没有问题,一切正常,直到 Android 6 命中,然后我还必须添加一个 HttpsURLConnection,因为不幸的是我们的客户没有那么幸运拥有更新的 Android 设备,所以我将此代码添加到我已经开发的网络类中:
public static HashMap<String, Object> callSOAPServer(StringBuffer soap, String action) {
HttpsURLConnection urlConnection = null;
boolean download = true;
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
try {
CertificateFactory cf = CertificateFactory.getInstance("X.509");
InputStream caInput = IsakApp.appContext.getResources().openRawResource(R.raw.thawte);
Certificate ca;
try {
ca = cf.generateCertificate(caInput);
} finally {
caInput.close();
}
String keyStoreType = KeyStore.getDefaultType();
KeyStore keyStore = KeyStore.getInstance(keyStoreType);
keyStore.load(null, null);
keyStore.setCertificateEntry("ca", ca);
String tmfAlgorithm = TrustManagerFactory.getDefaultAlgorithm();
TrustManagerFactory tmf = TrustManagerFactory.getInstance(tmfAlgorithm);
tmf.init(keyStore);
SSLContext context = SSLContext.getInstance("TLS");
context.init(null, tmf.getTrustManagers(), null);
URL url = new URL("whateverPage.com");
urlConnection =
(HttpsURLConnection) url.openConnection();
urlConnection.setSSLSocketFactory(context.getSocketFactory());
urlConnection.setRequestMethod("POST");
urlConnection.setConnectTimeout(20000);
urlConnection.setReadTimeout(20000);
urlConnection.setDoInput(true);
urlConnection.setDoOutput(true);
urlConnection.setRequestProperty("Content-type", "text/xml; charset=utf-8");
urlConnection.setRequestProperty("SOAPAction", action);
OutputStream reqStream = urlConnection.getOutputStream();
reqStream.write(soap.toString().getBytes());
InputStream resStream = urlConnection.getInputStream();
byte[] data = new byte[1024 * 1024];
ByteArrayOutputStream buffer = new ByteArrayOutputStream();
int count = urlConnection.getContentLength();
int total = 0;
int size = 0;
while ((count = resStream.read(data, 0, data.length)) != -1) {
buffer.write(data, 0, count);
}
buffer.flush();
String str = new String(buffer.toByteArray(), "UTF-8");
System.out.println("--------");
System.out.println(str);
String sn = str.replace("&", "AMP");
String[] stringArray = sn.split("\\r?\\n");
String soapNew = stringArray[1];
byte[] bytes = soapNew.getBytes("UTF-8");
HashMap<String, Object> xMap = new HashMap<String, Object>();
xMap.put(IsakApp.STATUS, "true");
xMap.put("soap", bytes);
resStream.close();
return xMap;
} catch (Exception e) {
e.printStackTrace();
} finally {
if( urlConnection != null) {
urlConnection.disconnect();
}
}
}
所以我的问题是,这是非常不可靠的,并不总是下载我需要的所有数据,但是当我使用通过 HttpClient 工作的旧设备时,这个问题并不存在。我的主要问题是:
System.err: org.apache.harmony.xml.ExpatParser$ParseException: At line 1, column 62973: no element found
System.err: at org.apache.harmony.xml.ExpatParser.finish(ExpatParser.java:545)
System.err: at org.apache.harmony.xml.ExpatParser.parseDocument(ExpatParser.java:475)
System.err: at org.apache.harmony.xml.ExpatReader.parse(ExpatReader.java:316)
System.err: at org.apache.harmony.xml.ExpatReader.parse(ExpatReader.java:279)
System.err: at com.czami.isakmobileapp.handling.XMLParser.parseSoap(XMLParser.java:153)

System.err: at com.czami.isakmobileapp.services.UpdateOneShot.onHandleIntent(UpdateOneShot.java:338)
问题是,那些 SOAP 消息,如果我将它们写在文件中,它们会正常发送,没有任何问题。而且在 Android 版本低于 6 的情况下,它在 HttpClient 上也能正常工作,如果它被弃用的话。现在我面临着相当大的问题,我不确定这有什么问题。一些 SOAP 消息通过没有问题,但似乎更大的消息不起作用。有人可以指出某个方向吗,我在这个应用程序上还有其他事情要做,这就像尝试了 2 天但仍然没有成功。我可能会查看解释 HttpsURLConnection 的每个页面、此处的每个页面以及代码下方存在此问题的页面。我很绝望。感谢您的任何回答。
