具有CXF的JAX-RS/请放心:处理多参数文件上传 [英] JAX-RS with CXF / rest-assured: Handling multiparam file upload

问题描述

我想上传JPG文件和JSON序列化的Java对象.在服务器上，我使用的是Apache CXF，在客户端上，我的集成测试是 rest-assured .

I want to upload a JPG file and a JSON-serialized Java object. On the server I am using Apache CXF, on the client I am integration testing with rest-assured.

我的服务器代码如下:

@POST
@Path("/document")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response storeTravelDocument(
        @Context UriInfo uriInfo, 
        @Multipart(value = "document") JsonBean bean,
        @Multipart(value = "image") InputStream pictureStream)
        throws IOException
{}

我的客户代码如下:

given().
    multiPart("document", new File("./data/json.txt"), "application/json").
    multiPart("image", new File("./data/image.txt"), "image/jpeg").
expect().
    statusCode(Response.Status.CREATED.getStatusCode()).
when().
    post("/document");

当我从文件中读取json部分时，一切正常，如第一多部分行中所示.但是，当我想序列化json实例时，我遇到了问题.我尝试了许多变体，但没有一个起作用.

Everything works fine when I read the json part from the file as in the first multiPart line. However, when I want to serialize the json instance I come into problems. I tried many variants, but none worked.

我认为该变体应该可以工作:在客户端上

I thought this variant should work: on the client

JsonBean json = new JsonBean();
json.setVal1("Value 1");
json.setVal2("Value 2");

given().
    contentType("application/json").
    formParam("document", json).
    multiPart("image", new File("./data/image.txt"), "image/jpeg").
...

并在服务器上

public Response storeTravelDocument(
    @Context UriInfo uriInfo, 
    @FormParam(value = "document") JsonBean bean,
    @Multipart(value = "image") InputStream pictureStream)

但没有.谁能告诉我应该怎么办?

but no. Can anyone tell me how it should be?

推荐答案

Multipart/form-data遵循多部分MIME数据流的规则，请参见问题166 .

Multipart/form-data follows the rules of multipart MIME data streams, see w3.org. This means that each part of the request forms a part in the stream. Rest-assured supports already simple fields (strings), files and streams, but not object serialization into a part. After asking on the mailing list, Johan Haleby (the author of rest-assured) suggested to add an issue. The issue is already accepted, see issue 166.

服务器将保持不变:

@POST
@Path("/document")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response storeTravelDocument(
        @Context UriInfo uriInfo, 
        @Multipart(value = "document") JsonBean bean,
        @Multipart(value = "image") InputStream pictureStream)
        throws IOException
{}

客户端代码如下:

given().
    multiPartObject("document", objectToSerialize, "application/json").
    multiPart("image", new File("./data/image.txt"), "image/jpeg").
expect().
    statusCode(Response.Status.CREATED.getStatusCode()).
when().
    post("/document");

也许名称"multiPartObject"将更改.一旦实施，我们就会看到.

Maybe the name "multiPartObject" will change. We will see once it is implemented.
