Java的HttpURLConnection不支持REPORT / PROPFIND-我该怎么办？ [英] Java's HttpURLConnection doesn't support REPORT/PROPFIND - what shall I do?

问题描述

HttpURLConnection仅支持GET，POST和HEAD之类的内容，但不支持REPORT / PROPFIND。我要实现一个CalDAV-Client，但是没有这些操作（如果要使用它们，我会收到ProtocolException），我必须使用auth等来编写/交付一个完整且庞大的HTTP库。

HttpURLConnection does only support things like GET, POST and HEAD - but no REPORT/PROPFIND. I'm going to implement a CalDAV-Client but without theese operations (if I want to use them I get a ProtocolException) I have to write/deliver a complete and huge HTTP library with auth and so on.

过度杀伤。

如何通过PROPFIND和REPORT发送请求？

How do I send requests with PROPFIND and REPORT?

推荐答案

对于PROPFIND方法，我在WebDav上也遇到了类似的问题。

I had similar problem on WebDav for PROPFIND method.

通过实现以下解决方案解决了该问题：
https://java.net/jira/browse/JERSEY-639

Solved the problem by implementing this solution: https://java.net/jira/browse/JERSEY-639

    try {
            httpURLConnection.setRequestMethod(method);
        } catch (final ProtocolException pe) {
            try {
                final Class<?> httpURLConnectionClass = httpURLConnection
                        .getClass();
                final Class<?> parentClass = httpURLConnectionClass
                        .getSuperclass();
                final Field methodField;
                // If the implementation class is an HTTPS URL Connection, we
                // need to go up one level higher in the heirarchy to modify the
                // 'method' field.
                if (parentClass == HttpsURLConnection.class) {
                    methodField = parentClass.getSuperclass().getDeclaredField(
                            "method");
                } else {
                    methodField = parentClass.getDeclaredField("method");
                }
                methodField.setAccessible(true);
                methodField.set(httpURLConnection, method);
            } catch (final Exception e) {
                throw new RuntimeException(e);

            }
     }
