无法将多部分/混合请求发送到基于Spring MVC的REST服务

Question

我有一个基于Spring MVC和Resteasy的REST服务，我需要通过发送多部分/混合请求来进行测试。

该服务的编码如下：

@POST
    @Path("/mixedMimeText")
    @Consumes("multipart/mixed")
    @ResponseStatus(HttpStatus.OK)
    public String createMime(@Context ServletContext servletContext, MultipartInput input) throws Exception, IOException {

        logger.info("Processing /mixedMimeText");

        for(InputPart p : input.getParts()){
            logger.info("Headers : " + p.getHeaders());
            logger.info("MediaType : " + p.getMediaType());
            logger.info("Body : " +  p.getBodyAsString());
            logger.info("--------------------------------------------------- ");
        }

        return "TEST";
    }

我正在使用以下文件作为多部分mime内容发送

--ABC123Boundary
Content-Type: text/xml

<?xml version="1.0" ?>

<account-id>XXXX-XXXX-XXXX-XXXX</account-id>

--ABC123Boundary--

我正在使用curl客户端通过以下命令发送请求：

curl -X POST http://localhost:8080/MyRestServices/restportal/services/mixedMimeText -i -H "Content-Type: multipart/mixed; boundary="--ABC123Boundary" -T myfile.txt

该请求确实到达了服务，但是我在JBOSS终端上看到的只是它产生了以下错误，这实际上没有任何意义。没有堆栈跟踪或任何其他错误。

21:48:37,174 WARN  [org.apache.james.mime4j.parser.MimeEntity] (http--127.0.0.1-8080-1) Unexpected end of headers detected. Higher level boundary detected or EOF reached.
21:48:37,175 WARN  [org.apache.james.mime4j.parser.MimeEntity] (http--127.0.0.1-8080-1) Invalid header encountered
21:48:37,176 WARN  [org.apache.james.mime4j.parser.MimeEntity] (http--127.0.0.1-8080-1) Body part ended prematurely. Boundary detected in header or EOF reached.

听起来内容有问题，但我不太确定。

编辑

@Perception-我按如下所示更改了命令，但仍会产生相同的错误

curl http://localhost:8080/MyRestServices/restportal/services/mixedMimeText --data-binary @myfile.txt -X POST -i -H "Content-Type: multipart/mixed; boundary=--ABC123Boundary"

我想知道MultipartInput结构是否期望内容采用其他格式。

编辑

看起来正在发送的数据是正确的。这是我使用–trace选项运行命令时的输出

curl http://localhost:8080/MyRestServices/restportal/services/mixedMimeText --data-binary @myfile.txt -X POST -i -H "Content-Type: multipart/mixed; boundary=--ABC123Boundary" --trace trace.txt

跟踪输出

Answer 1

请查看：
7.2.1中的http://www.w3.org/Protocols/rfc1341/7_2_Multipart.html，其中显示了示例，并讨论了如何指定和使用边界。摘要示例：

1.在标题中指定：

Content-Type: multipart/mixed;boundary=gc0p4Jq0M2Yt08jU534c0p

2.在每个部分的前面加上-和边界：

--gc0p4Jq0M2Yt08jU534c0p

3.最后一个边界是-以及边界和-：

--gc0p4Jq0M2Yt08jU534c0p--

希望能有所帮助。最近我碰巧不得不处理这个问题。
