玩:是否可以提取表单数据而不将其绑定到模型? [英] Play: Is it possible to extract form data without binding it to a model?

问题描述

此刻，我正试图从表单POST请求中提取各个表单字段的信息，我以为会是这样.这是一个例子:

At the moment I'm trying to extract information of individual form fields from form POST requests, & I thought it would be something like this. Here's an exmaple:

在HTML中

<form action="..." method="POST">
    <input name="field-name">
    <input type="submit">
</form>

并从Controller获取信息:

And to get the information from the Controller:

String field = Form.form.get('field-name');

我一直在搜索文档，发现的所有示例都在将请求绑定到模型类，该类生成模型.在某些情况下，我不想这样做，因为我想拉开单个字段并处理数据.

I've been searching the docs, and all the examples I've found have been binding a request to a model class, which generates a model. I don't want to this in a few cases, as I want to pull the indivisual fields and manipulate the data.

更正了一些深夜拼写错误

edit: corrected some late night spelling errors

推荐答案

您可以使用

You can use a DynamicForm to get fields by name in a controller.

DynamicForm form = form().bindFromRequest();
String fieldValue = form.get("field-name");

或更短:

String name = form().bindFromRequest().get("field-name");
