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

前端可以将Content-Type从'application/x-www-form-urlencoded;charset=UTF-8'改为'application/json;charset=UTF-8'来解决该问题。这是因为SpringMVC默认使用的是MappingJackson2HttpMessageConverter来处理json数据，而'application/x-www-form-urlencoded'格式的数据需要使用FormHttpMessageConverter来处理。因此，如果前端发送的数据格式不是json格式，SpringMVC就会报错。将Content-Type改为'application/json;charset=UTF-8'后，前端发送的数据就会被正确地解析为json格式，从而避免了该错误的发生。

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.

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

这个错误通常是由于请求的Content-Type与后台服务不匹配引起的。在前端POST表单提交时，Content-Type默认为'application/x-www-form-urlencoded;charset=UTF-8'，而后台服务可能只支持'application/json'或其他类型的Content-Type。解决方法如下：
1.在前端代码中设置Content-Type为后台服务支持的类型，例如'application/json'。
2.在后台服务中添加对'application/x-www-form-urlencoded;charset=UTF-8'的支持。
3.在前端代码中使用FormData对象来提交表单数据，这样可以自动设置Content-Type为'application/x-www-form-urlencoded;charset=UTF-8'，并且可以处理文件上传等复杂情况。
