我一天中的大部分时间都试图以各种组合方式工作。最初我通过使用Authenticator.setDefault（如在类文件的底部看到的那样）在java中找到了这个工作。但是，当我转移到android时它不再有效。
之后我尝试添加代码来设置URL连接，如下所示，但仍然会出现相同的错误。
以下是按下按钮时MainActivity调用的代码
注意：当前代码使用gist URL 注意：在不使用URLConnection的情况下，在Java工作之后，尽快使用注释掉的Authentication.setDefault。 注意：我尝试了各种组合，似乎无法从log cat中获得任何不同。

@Override

final String login = "loginStuff";
final String password = "passwordStuff";
String results = "";
final String creds= "loginstuff:passwordStuff";
String strURL = "https://rest_of_url";
//BELOW i have included a gist that returns the same JSON as the original strURL
strURL = "https://gist.githubusercontent.com/anonymous/d9daef9da096f310684f/raw/7bebd7379363fd32c35cc6b51a4096bafb2c1bab/count";
// Works fine with the above URL
JsonFactory jfactory = new JsonFactory();
Log.v("hola2", "something3");
JsonParser jParser;
try {
URL url = new URL(strURL);
URLConnection urlConnection = url.openConnection();
// urlConnection.setDoInput(false);
// urlConnection.setDoOutput(true);
//urlConnection.setRequestMethod("GET");
String basic = "Basic " + Base64.encodeToString(creds.getBytes(), Base64.NO_WRAP );
urlConnection.setRequestProperty("Authorization", basic);
jParser = jfactory.createParser(url);
Log.v("hola3", "t4");
while (jParser.nextToken() != JsonToken.END_OBJECT) {
//for (int i = 0 ; i<2; i++){
String fieldname = jParser.getCurrentName();
Log.v("hola3", "t5");
//Log.v("output", jParser.getText());
if ("count".equals(fieldname)) {
// current token is "name",
// move to next, which is "name"'s value
jParser.nextToken();
//System.out.println(jParser.getText());
results = results + jParser.getText();
}
else {
Log.v("error", "else error");
}
}
jParser.close();
//urlConnection.close();
}
catch (IOException error) {
//Throwable e = null;
// TODO Auto-generated catch block
error.printStackTrace();
}
Log.v("hola3", results);
return results;
}
}
//Authenticator.setDefault(new Authenticator() {
//
// @Override
// protected PasswordAuthentication getPasswordAuthentication() {
// return new PasswordAuthentication(login, password.toCharArray());
// }
//});
//
当您注释掉gist url并让常规auth运行时，这就是logcat。它指出了创建jparser的第64行。我不确定为什么会这样看，因为它不会发生在gist url上。

我只是尝试使用Android使用REST API进行身份验证。我非常感谢您提供的任何帮助！
我最好的猜测是Jackson解析器没有正确使用开放URL连接。如果可能的话，我更愿意避免使用缓冲区/阅读器。我有点担心它会降低性能。
