[英]JAX-RS: Consuming JSON POST data without setting Content-Type header to application/json
I have implemented a REST service using Jersey that takes JSON POST data and creates an object from a POJO model.我已经使用 Jersey 实现了一个 REST 服务,它采用 JSON POST 数据并从 POJO 模型创建一个对象。 However, in order for this to work, I have to set the Content-Type to application/json (ie,
-H "Content-Type: application/json"
).但是,为了使其工作,我必须将 Content-Type 设置为 application/json(即
-H "Content-Type: application/json"
)。 What I'd like is to be able to consume JSON POST request body without the user having to set the header, basically like Elasticsearch works:我想要的是能够使用 JSON POST 请求正文而无需用户设置标头,基本上就像 Elasticsearch 一样:
POST /test_index/_search?search_type=count
{
"aggs": {
"nested_authors": {
"nested": {
"path": "authors"
},
"aggs": {
"author_last_names": {
"terms": {
"field": "authors.last_name"
}
}
}
}
}
}
Here's the relevant code:这是相关的代码:
@POST
@Path("/person")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public Response postPerson(PostBody pb) {
System.out.println(pb.getEmails());
}
I faced a similar problem.我遇到了类似的问题。 Since in my opinion a well defined API - which doesn't share its endpoints with any other system - should not need to depend on clients specifying the correct
Content-Type
, I created a workaround.由于在我看来定义明确的 API - 不与任何其他系统共享其端点 - 不应该依赖于指定正确
Content-Type
客户端,所以我创建了一个解决方法。 In this workaround, I add an annotation to those resource methods where I want Jersey to always attempt to read the input according to a server-defined Content-Type
.在此解决方法中,我向那些希望 Jersey 始终尝试根据服务器定义的
Content-Type
读取输入的资源方法添加注释。 Whenever this annotation is present, a ResourceFilter
will override the Content-Type
header in the request, to whatever is specified in the annotation.每当此注释出现时,
ResourceFilter
将覆盖请求中的Content-Type
标头,以注释中指定的任何内容。
I have detailed the process in my answer here .我在我的回答中详细说明了这个过程。
Figured it out.弄清楚了。 I'm now accepting "application/json" and "application/x-www-form-urlencoded" content types.
我现在接受“application/json”和“application/x-www-form-urlencoded”内容类型。 Here's the code:
这是代码:
@POST
@Path("/person")
@Consumes({MediaType.APPLICATION_JSON,MediaType.APPLICATION_FORM_URLENCODED})
@Produces(MediaType.APPLICATION_JSON)
public Response postPerson(String body) throws IOException {
ObjectMapper mapper = new ObjectMapper();
PostBody pb = mapper.readValue(body, PostBody.class);
System.out.println(pb.getEmails());
}
Though, after thinking for a bit, I probably should require the Content-Type header considering it contains a JSON request body, but that's another discussion entirely.不过,考虑一下,考虑到它包含一个 JSON 请求正文,我可能应该需要 Content-Type 标头,但这完全是另一个讨论。
