向 REST 服务发布复杂参数，请求 URL 和 Body 是什么样的 [英] POST complex parameters to REST service what would request URL and Body look like

问题描述

所以我站起来休息.它将请求一个非常复杂的资源的帖子.实际后端需要多个(19！)参数.其中之一是字节数组.听起来这需要由客户端序列化并发送到我的服务.

So I am standing up a rest service. It is going to request a post to a resource that is pretty complex. The actual backend requires multiple (19!) parameters. One of which is a byte array. It sounds like this is going to need to be serialized by the client and sent to my service.

我正在尝试了解如何正确处理此问题的方法.我在想这样的事情

I am trying to understand how I can right a method that will handle this. I am thinking something like this

@POST
@Path("apath")
@Consumes(MediaType.APPLICATION_JSON, MediaType.TEXT_HTML)
public Response randomAPI(@Parameter apiID, WhatParamWouldIPutHere confused){
}

我将使用哪些参数类型来捕获入站(序列化)发布数据.客户端 URI 会是什么样子?

What parameter types would I do to capture that inbound (Serialized) Post data. And what would the client URI look like?

推荐答案

为了得到请求的所有参数，你可以使用 @Context UriInfo 作为你的 randomAPI 的参数代码>方法.

In order to get all the parameters of the request you can use @Context UriInfoas parameter of your randomAPI method.

然后使用UriInfo#getQueryParameters() 获取完整的MultivaluedMap 参数.

如果您希望将 MultivaluedMap 转换为简单的 HashMap，我也为此添加了代码.

if you wish to convert the MultivaluedMap to a simple HashMap I added the code for that too.

所以你的方法基本上看起来像这样:

so your method will basically look like something like this:

@POST
@Path("apath")
@Consumes(MediaType.APPLICATION_JSON, MediaType.TEXT_HTML)
public Response randomAPI(@Context UriInfo uriInfo){
    Map params= (HashMap) convertMultiToHashMap(uriInfo.getQueryParameters());
    return service.doWork(params);
}

public Map<String, String> convertMultiToHashMap(MultivaluedMap<String, String> m) {
        Map<String, String> map = new HashMap<String, String>();
        for (Map.Entry<String, List<String>> entry : m.entrySet()) {
            StringBuilder sb = new StringBuilder();
            for (String s : entry.getValue()) {
                sb.append(s);
            }
            map.put(entry.getKey(), sb.toString());
        }
        return map;
    }

附加信息:

@Context 注释允许您注入javax.ws.rs.core.HttpHeaders、javax.ws.rs.core.UriInfo、javax.ws.rs.core.Request, javax.servlet.HttpServletRequest,javax.servlet.HttpServletResponse、javax.servlet.ServletConfig、javax.servlet.ServletContext 和 javax.ws.rs.core.SecurityContext对象.

The @Context annotation allows you to inject instances of javax.ws.rs.core.HttpHeaders, javax.ws.rs.core.UriInfo, javax.ws.rs.core.Request, javax.servlet.HttpServletRequest, javax.servlet.HttpServletResponse, javax.servlet.ServletConfig, javax.servlet.ServletContext, and javax.ws.rs.core.SecurityContext objects.
