前端代码 Content type 'text/html;charset=UTF-8' not supported"

这个问题通常出现在使用 Spring MVC 框架时，表示请求的 Content-Type 不被支持。可以通过在 Controller 方法上添加 @RequestMapping 注解并指定 consumes 属性来解决这个问题。例如：

@RequestMapping(value = "/example", method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<?> exampleMethod(@RequestBody ExampleDto exampleDto) {
// do something
return ResponseEntity.ok().build();
}

HttpMediaTypeNotSupportedException: Content type '/;charset=UTF-8' not supported报这个错上述请求怎么修改

根据错误提示，这个请求的Content-Type类型似乎不正确，可能是`/;charset=UTF-8`这个值造成的。所以，你需要修改请求头中的Content-Type类型为正确的值。

假设你想要发送的Content-Type是`application/json`，那么你可以将请求头中的Content-Type设置为`application/json;charset=UTF-8`。修改后的请求如下所示：

POST {{baseUrl}}/app/notice/save 
Accept: application/json 
token: knheSyuWdTcXy 
Content-Type: application/json;charset=UTF-8

{
  "key1": "value1",
  "key2": "value2"
}

注意，如果你需要发送的是其他类型的数据，你需要将Content-Type修改为对应的值。例如，如果你要发送XML格式的数据，Content-Type就应该是`application/xml;charset=UTF-8`。

Content type application/x-www-form-urlencoded;charset=UTF-8 not supported

As an AI language model, I cannot access or interact with any server or application. However, I can provide you with some information on the error message you have mentioned.

The error message "Content type application/x-www-form-urlencoded;charset=UTF-8 not supported" typically occurs when a client sends a request to a server with a content type that is not supported by the server.

The content type "application/x-www-form-urlencoded" is commonly used for HTML form submissions and is encoded in a key-value pair format. The "charset=UTF-8" parameter specifies the character encoding used for the data.

To resolve this error, the client should send the request with a supported content type or the server should be configured to support the requested content type.
