【问题描述】:
我正在尝试在输入中插入文本并提交它,以便我可以在后端获取它。 这是它在前端的样子:
<form th:action="@{/student/mypage/}">
<label><h3><b>Friend Token:</b></h3>
</label><br>
<input type="text" th:name = "friendToken"/>
<input type="submit" />
</form>
这就是它在后端的样子:
@Controller
@RequestMapping(path = "/student/mypage")
public class MyPageController {
//Fields
private final StudentService studentService;
private final StudentAccountService studentAccountService;
//Constructor
@Autowired
public MyPageController(StudentService studentService, StudentAccountService studentAccountService) {
this.studentService = studentService;
this.studentAccountService = studentAccountService;
}
/* ~~~~~~~~~~~ Get MyPage View ~~~~~~~~~~~ */
@GetMapping
@PreAuthorize("hasRole('ROLE_STUDENT')")
public String getMyPage(Model model)
{
LoggedAccount loggedAccount = new LoggedAccount();
if(loggedAccount.checkIfStandardAccLogged())
{
model.addAttribute("devUsernameAccount", loggedAccount.getLoggedUsername());
}
else
{
StudentAccount loggedStudentAccount = studentAccountService.getLoggedStudentAccount();
//query call in db to get info of logged student
Student infoStudent = studentService.findStudentByNameAndSurname(loggedStudentAccount);
//getting info about logged acc (credentials) && student info
model.addAttribute("loggedStudentAccount", loggedStudentAccount);
model.addAttribute("infoStudent", infoStudent);
//checkup in case we log in with a dev account
model.addAttribute("isDevAcc", loggedAccount.checkIfStandardAccLogged().toString());
}
return "pages/layer 4/info pages/mypage";
}
@RequestMapping(value = "/{friendToken}", method = RequestMethod.POST)
public void updateFriendToken(
@PathVariable(required = false, name = "friendToken") String friendToken,
Model model
)
{
System.out.println("Friend Tokenul este " + friendToken);
}
}
如您所见,当我按下提交调用名为 updateFriendToken 的请求方法并从 url 获取路径变量并在控制台中打印时,我想要。 我知道我可能做错了很多事情,所以请随意更改 html 代码和 java。 我的项目使用 SpringBoot 和 Java 作为后端,HTML、CSS、JS 脚本和 Thymeleaf 作为前端。 我正在添加网站的图片,我知道我的 url 不正确,并且我无法以这种方式获取任何路径变量,但我真的不知道如何获取我在 FriendToken 文本框中插入的文本。
非常感谢您的帮助!
