如何使用httpclient或HttpURLConnection调用jersey rest服务与列表@FormParam

我正在尝试从android调用jersey服务

@POST
@Path("/share")
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_FORM_URLENCODED)
public Response shareProgramVideo(@FormParam("from")Integer from, @FormParam("to")List<Integer> to,@FormParam("programIds")List<Integer> programIds)

该服务可以正常工作与HTML表单

<html>
    <head>
        <title>REST with Forms</title>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    </head>
    <body>
        <br />
        <form method="post" action="../dataService/rest/secure/program/share">
             from: <input type="text" name="from" id="from" /><br />
             to 1: <input type="text" name="to" id="to" /><br />
             to 2: <input type="text" name="to" id="to" /><br />
             programIds 1: <input type="text" name="programIds" id="programIds" /><br />
             programIds 2: <input type="text" name="programIds" id="programIds" /><br />
            <input type="submit" value="Submit" />
        </form>
    </body>
</html>

我正在使用android和HttpRequest库(https://github.com/kevinsawicki/http-request)但是它给了我400个坏请求错误

     List<Integer> programs = new ArrayList<Integer>();
programs.add(1);
programs.add(2);
List<Integer> to = new ArrayList<Integer>();
to.add(1);
to.add(2);
Map<String, Object> data = new HashMap<String, Object>();
data.put("from", 1);
data.put("to", to);
data.put("programIds", programs);
HttpRequest request = HttpRequest.post(url)
        .basic(WebServiceConfig.ADMIN, WebServiceConfig.ADMIN_PSW).contentType("application/x-www-form-urlencoded")
        .acceptJson().form(data);
if (request.created() || request.ok()) {
    return true;
} else {
    Log.e("CreateUserProgramTask",
            "request.code()=" + request.code() + "request.body()="
                    + request.body());
    return false;
}

我不知道你正在使用的库，但我认为问题可能在于你创建'programs'和'to'参数的方式:

List<Integer> programs = new ArrayList<Integer>();
programs.add(1);
programs.add(2);
List<Integer> to = new ArrayList<Integer>();
to.add(1);
to.add(2);
Map<String, Object> data = new HashMap<String, Object>();
data.put("from", 1);
data.put("to", to);
data.put("programIds", programs);

似乎库只是在列表中做一个toString()调用，但我认为你应该序列化为:

programs = "program1,program2"
to = "to1,to2"

我认为这不是数据映射中所写的内容
