Resteasy（multipart/form-data）：如何读取多值字段值到列表？

发布于 2025-01-05 01:32:32 字数 682 浏览 1 评论 0原文

我需要一点帮助来放松。我有一个包含一些多值字段的多部分网络表单。我的主题参数请求数据：

------WebKitFormBoundary2sX84QQsaESs9qTv
Content-Disposition: form-data; name="topics"

3569
------WebKitFormBoundary2sX84QQsaESs9qTv
Content-Disposition: form-data; name="topics"

18421
------WebKitFormBoundary2sX84QQsaESs9qTv
Content-Disposition: form-data; name="topics"

9703

如何读取“主题”参数以列出？这就是我的主题参数属性的注释方式

@FormParam("topics")
private String[]  topics;

，但我得到一个例外：

Unable to find a MessageBodyReader for media type: text/plain;charset="us-ascii" and class type [Ljava.lang.String;

任何帮助或示例将不胜感激。

亲切的问候

I need a little help with resteasy.
I have a multipart web form with some multi-value fields.
My request data for topics parameter:

------WebKitFormBoundary2sX84QQsaESs9qTv
Content-Disposition: form-data; name="topics"

3569
------WebKitFormBoundary2sX84QQsaESs9qTv
Content-Disposition: form-data; name="topics"

18421
------WebKitFormBoundary2sX84QQsaESs9qTv
Content-Disposition: form-data; name="topics"

9703

How can I read "topics" parameter to list ?
This is how my property for topics parameter is annotated

@FormParam("topics")
private String[]  topics;

but I get an exception:

Unable to find a MessageBodyReader for media type: text/plain;charset="us-ascii" and class type [Ljava.lang.String;

Any help or example would be greatly appreciated.

Kind regards

Armando

这是您要找的吗？

@PUT
@Path("/someurl")
@Consumes("multipart/form-data")
@Produces("text/plain;charset=UTF-8")
public String someUrl(MultipartFormDataInput form) 
{
    try {
        List<InputPart> l = form.getFormDataMap().get("topics");
        String topic1 = l.get(0).getBodyAsString();
        String topic2 = l.get(1).getBodyAsString();
        String topic3 = l.get(2).getBodyAsString();
        // do something with the topics ...
    } catch (IOException e) {
        e.printStackTrace();
    }
    return "something went wrong";
}

Is this what you're looking for?

@PUT
@Path("/someurl")
@Consumes("multipart/form-data")
@Produces("text/plain;charset=UTF-8")
public String someUrl(MultipartFormDataInput form) 
{
    try {
        List<InputPart> l = form.getFormDataMap().get("topics");
        String topic1 = l.get(0).getBodyAsString();
        String topic2 = l.get(1).getBodyAsString();
        String topic3 = l.get(2).getBodyAsString();
        // do something with the topics ...
    } catch (IOException e) {
        e.printStackTrace();
    }
    return "something went wrong";
}
