如何将百里香叶输入字段中的变量作为 PathVariable 传递 [英] How to pass variable from thymeleaf input field as PathVariable

问题描述

我有控制器:

@Slf4j
@RestController
@RequestMapping("/languages")
{
    @PostMapping("/{arg}")
    public void testLanguage(@PathVariable String arg) {
        log.info("testLanguage(): " + arg);
    }
}

html 页面:

<form method="post" th:action="@{/languages/{arg}(arg=${arg})}">
    <label>Enter any message here:
        <!--How I should write my input field(what parameters must be added)
        to receive this variable in cntroller as @PathVariable-->
        <input type="text" th:value="${arg}" th:name="arg">
    </label>
    <input type="submit" value="Test with ARG">
</form>

如何从输入字段传递arg变量并在控制器中接收它?

推荐答案

没有 Thymeleaf 方法可以做到这一点.您必须使用 JavaScript 来构建该 url onsubmit，或者创建另一个控制器方法来为您进行转发.像这样的东西，例如:

There isn't a Thymeleaf way to do this. You'll have to either use JavaScript to build that url onsubmit, or alternatively create another controller method to do the forwarding for you. Something like this for example:

@PostMapping("/")
public void forwardLanguage(@RequestParam String arg) {
    return "redirect:/language/" + arg;
}
