问题描述

我有一个Spring MVC和Resteasy基于REST服务，我需要测试通过发送一个多部分/混合请求。



该服务编码如下：

  @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（----------------------------------------- ----------）; 
} 
 
 returnTEST; 
}

我使用以下文件作为multipart mime内容发送

   -  ABC123Boundary 
 Content-Type：text / xml 
 
<？xml version = 1.0→> 
< request> 
< account-id> XXXX-XXXX-XXXX-XXXX< / account-id>

 --ABC123Boundary 
 Content-Type：text / xml

< snip> 
 // + f ////// 2f ///////// 5 // n ////////// 9n 
 
 --ABC123Boundary -

我使用curl客户端使用以下命令发送请求：

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

请求获得服务，所有我在JBOSS终端上看到的是它产生以下错误，这没有真正有意义，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）检测到头的意外结束。检测到更高级别的边界或达到EOF。 
 21：48：37,175 WARN [org.apache.james.mime4j.parser.MimeEntity]（http  -  127.0.0.1-8080-1）遇到无效标题

听起来内容有问题，但我不太确定。



编辑



@Perception - 我改变了命令，但仍然产生相同的错误

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

MultipartInput结构期望内容采用不同的格式。



编辑



看起来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 -HContent-Type：multipart / mixed; boundary =  -  ABC123Boundary--trace trace.txt

跟踪输出

解决方案
请参阅：
  http://www.w3.org/Protocols/rfc1341/7_2_Multipart.html 中显示了示例，并讨论了如何指定边界用过的。总结示例：
 
 
 
  1。在标头中指定： 
  Content-Type：multipart / mixed; boundary = gc0p4Jq0M2Yt08jU534c0p 
  
  2。在每个部分之前加上 - 和边界： 
   -  gc0p4Jq0M2Yt08jU534c0p 
  
  3。最后边界是 - 和边界和 - ： 
   -  gc0p4Jq0M2Yt08jU534c0p-- 
  
希望有帮助。我最近不得不处理这个问题。
 
I have a Spring MVC and Resteasy based REST service that i need to test by sending a multipart/mixed request. 



The service is coded as follows: 
@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";
    }

I am using the following file to send as the multipart mime content
--ABC123Boundary
Content-Type: text/xml

<?xml version="1.0" ?>
<request>
<account-id>XXXX-XXXX-XXXX-XXXX</account-id>

--ABC123Boundary--

I am sending the request using the curl client with the following command:
curl -X POST http://localhost:8080/MyRestServices/restportal/services/mixedMimeText -i -H "Content-Type: multipart/mixed; boundary="--ABC123Boundary" -T myfile.txt

The request does get to the service but all i see on the JBOSS terminal is that it produces the following error which does not really make sense. There is no stack trace or any other errors. 
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.

It sounds like there is something wrong with the content but i am not quite sure. 



Edit



@Perception - i changed the command as follows but it still produces that same error
curl http://localhost:8080/MyRestServices/restportal/services/mixedMimeText --data-binary @myfile.txt -X POST -i -H "Content-Type: multipart/mixed; boundary=--ABC123Boundary"

I wonder if the MultipartInput structure expects the content to be in a different format. 



Edit



It looks like the data being sent is correct. Here is the output when i run the command using the --trace option
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

 解决方案 
Please look at:
http://www.w3.org/Protocols/rfc1341/7_2_Multipart.html in 7.2.1 it shows examples and discusses how the boundary should be specified and used.  A summary example:



1. Specify in header:
Content-Type: multipart/mixed;boundary=gc0p4Jq0M2Yt08jU534c0p

2. Precede each part with -- and boundary:
--gc0p4Jq0M2Yt08jU534c0p

3. Last boundary is  -- and boundary and -- :
--gc0p4Jq0M2Yt08jU534c0p--

Hope that helps.  I happened to have had to deal with this myself recently.
