java - apache httpclient - 如何反序列化响应

问题描述

我正在通过 HttpClient 调用外部 Web 服务，但在转换我得到的响应时遇到了问题。这是一个像这样的mtom响应：

--MIMEBoundaryurn_uuid_5CF5D04EE84169F28B1567408992661 内容类型：application/xop+xml；字符集=UTF-8；type="text/xml" Content-Transfer-Encoding: 二进制 Content-ID: <0.urn:uuid:5CF5D04EE84169F28B1567408992662@apache.org>

我试图在这里和那里遵循建议，我想出了这个测试类https://svn.apache.org/repos/asf/cxf/branches/2.7.x-fixes/api/src/test/java/org/ apache/cxf/attachment/AttachmentDeserializerTest.java

但不幸的是它不起作用或更好，我忘记做一些很容易的事情。

这是我为它编写的一些代码：

HttpResponse 响应 = client.execute(httpPost); HttpEntity 实体 = response.getEntity();

    String ct = response.getLastHeader("Content-Type").toString().replace("Content-Type: ", "");

    String responseContent = null;

    if (entity != null) {
        responseContent = EntityUtils.toString(response.getEntity(), StandardCharsets.UTF_8.name());

        MessageImpl msg = new MessageImpl();
        Exchange exchange = new ExchangeImpl();
        msg.setExchange(exchange);
        InputStream is = new ByteArrayInputStream(responseContent.getBytes());
        msg.put(Message.CONTENT_TYPE, ct);
        msg.setContent(InputStream.class, is);
        AttachmentDeserializer deserializer = new AttachmentDeserializer(msg);
        deserializer.initializeAttachments();
        InputStream attBody = msg.getContent(InputStream.class);

        String attMimeType = msg.getAttachmentMimeType();

        Collection<Attachment> atts = msg.getAttachments();
        Iterator<Attachment> itr = atts.iterator();
        Attachment a = itr.next();
        InputStream attIs = a.getDataHandler().getInputStream();

    }

不幸的是，集合中没有元素......我的目标是处理元素，但我陷入了这种转换。预先感谢您的支持。
