我收到此错误:HTTP 状态 405 - 不支持请求方法“POST”
我要做的是制作一个带有下拉框的表单，该下拉框根据在另一个下拉框中选择的其他值进行填充。例如，当我在 customerName 框中选择一个名称时，应该运行 .jsp 页面中的 onChange 函数，然后再次加载提交的页面，并使用 customerCountry 框。
但是我收到了这个 HTTP 状态 405 错误。我在互联网上搜索了解决方案，但找不到任何有用的东西。这是我的代码的相关部分:
jsp页面的一部分
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
<style>
.error { color: red; }
</style>
<script>
function repopulate(){
document.deliveryForm.submit();
}
function setFalse(){
document.getElementById("hasId").value ="false";
document.deliveryForm.submit();
// document.submitForm.submit(); (This was causing the error)
}
</script>
</head>
<body>
<h1>Create New Delivery</h1>
<c:url var="saveUrl" value="/test/delivery/add" />
<form:form modelAttribute="deliveryDtoAttribute" method="POST" action="${saveUrl}" name="deliveryForm">
<table>
<tr>
<td><form:hidden id="hasId" path="hasCustomerName" value="true"/></td>
</tr>
<tr>
<td>Customer Name</td>
<td><form:select path="customerName" onChange="repopulate()">
<form:option value="" label="--- Select ---" />
<form:options items="${customerNameList}" />
</form:select>
</td>
<td><form:errors path="customerName" cssClass="error" /></td>
</tr>
<tr>
<td>Customer Country</td>
<td><form:select path="customerCountry">
<form:option value="" label="--- Select ---" />
<form:options items="${customerCountryList}" />
</form:select>
</td>
<td><form:errors path="customerCountry" cssClass="error" /></td>
</tr>
</form:form>
<form:form name="submitForm">
<input type="button" value="Save" onClick="setFalse()"/>
</form:form>
</body>
</html>
Controller 的一部分:
@RequestMapping(value = "/add", method = RequestMethod.GET)
public String getDelivery(ModelMap model) {
DeliveryDto deliveryDto = new DeliveryDto();
model.addAttribute("deliveryDtoAttribute", deliveryDto);
model.addAttribute("customerNameList",
customerService.listAllCustomerNames());
model.addAttribute("customerCountryList", customerService
.listAllCustomerCountries(deliveryDto.getCustomerName()));
return "new-delivery";
}
// I want to enter this method if hasId=true which means that a value in the CustomerName
// drop down list was selected. This should set the CountryList to the corresponding values
// from the database. I want this post method to be triggered by the onChange in the jsp page
@RequestMapping(value = "/add", method = RequestMethod.POST, params="hasCustomerName=true")
public String postDelivery(
@ModelAttribute("deliveryDtoAttribute") DeliveryDto deliveryDto,
BindingResult result, ModelMap model) {
model.addAttribute("deliveryDtoAttribute", deliveryDto);
model.addAttribute("customerNameList",
customerService.listAllCustomerNames());
model.addAttribute("customerCountryList", customerService
.listAllCustomerCountries(deliveryDto.getCustomerName()));
return "new-delivery";
}
// This next post method should only be entered if the save button is hit in the jsp page
@RequestMapping(value = "/add", method = RequestMethod.POST, params="hasCustomerName=false")
public String postDelivery2(
@ModelAttribute("deliveryDtoAttribute") @Valid DeliveryDto deliveryDto,
BindingResult result, ModelMap model) {
if (result.hasErrors()) {
model.addAttribute("deliveryDtoAttribute", deliveryDto);
model.addAttribute("customerNameList",
customerService.listAllCustomerNames());
model.addAttribute("customerCountryList", customerService
.listAllCustomerCountries(deliveryDto.getCustomerName()));
return "new-delivery";
} else {
Delivery delivery = new Delivery();
//Setters to set delivery values
return "redirect:/mis/home";
}
}
我怎么会收到这个错误？任何帮助将非常感激!谢谢
编辑:将 hasId 更改为 hasCustomerName。我仍然收到 HTTP Status 405 - Request method 'POST' not supported 错误。
EDIT2:注释掉 setFalse 函数中导致错误的行
//D
最佳答案
我不确定这是否有帮助，但我遇到了同样的问题。
您正在使用带有 CSRF 保护的 springSecurityFilterChain。这意味着当您通过 POST 请求发送表单时，您必须发送 token 。尝试将下一个输入添加到您的表单中:
<input type="hidden" name="${_csrf.parameterName}" value="${_csrf.token}"/>
