Spray Client Post Multipart

Question

我想使用Spray将多部分表单发布到服务器.特别是我想张贴一张图片.

我遇到麻烦的是文件到多部分的编组.尽管在Spray中他们提到了默认的Marshaller,但我似乎无法将两者结合在一起.

我目前正在使用Spray 1.0-M7,因为我没有迁移到Scala 2.10,如果示例可以符合该分支,那将是非常好的.

我现在拥有的是:

val bis = new BufferedInputStream(new FileInputStream(file))
val bArray = Stream.continually(bis.read).takeWhile(-1 !=).map(_.toByte).toArray
Logger.error("About to post with spray")
pipeline(Post("/saveImageWithSpray", bArray)) 

当然,我得到一个错误说:

For request 'POST /saveImageWithSpray' [Missing boundary header]

我找到的大多数示例使用内容(作为[X])指令进行编组,但我没有使用Spray-routing,我只需要在另一个框架上构建的应用程序中使用spray-client执行post.

谢谢

编辑

我实际上设法像这样编组:

val pipeline = (
 addHeader("Content-Type", "multipart/form-data")
  ~> sendReceive(conduit)
)
val bis = new BufferedInputStream(new FileInputStream(file, "UTF-8"))
val bArray = Stream.continually(bis.read).takeWhile(-1 !=).map(_.toByte).toArray

Logger.error("About to post with spray "+bArray.length.toString)
pipeline(Post("/saveImageWithSpray", MultipartFormData(Map(
  "spray-file" -> BodyPart(
    HttpEntity(Some(HttpBody(ContentType(MediaTypes.`image/gif`), bArray))),
    HttpHeaders.`Content-Disposition`("form-data", Map("name" -> "spray-file","filename"->"Fuurin (Glass Wind Chime).gif"))::Nil
    )
  ))))

不幸的是,这仍然没有工作,数据正在转移,但服务器无法找到该文件.

wireshark捕获显示以下内容:

POST /saveImageWithSpray HTTP/1.1

User-Agent: spray-can/1.0-M7

这是对使用Advanced Rest Client进行的有效请求的捕获:

@grandes 感谢您的回复。我使用 newman Rest 客户端库（https://github.com/stackmob/newman）发送 http 请求，但必须手动创建 MultipartFormData 并且它可以工作。这将在不久的将来在纽曼中得到修复。这是我用来手动构建多部分表单数据的链接：http://www.w3.org/TR/html401/interact/forms.html#h-17.13.4.2
