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

回答: 这个错误是由于后端接收到了一个不支持的Content-Type类型引起的。通常情况下，如果没有明确指定Content-Type类型，默认的Content-Type类型是"application/x-www-form-urlencoded"。而后端通常使用"application/json;charset=utf-8"格式来解析请求，因此导致解析失败。 如果在POST请求中，前端的请求头没有正确指定Content-Type类型或者指定的类型与后端不一致，就会出现这个错误。一种解决办法是检查请求头中的Content-Type属性，确保前端和后端使用的是相同的Content-Type类型。另外，如果前端的POST请求中的body是Json对象，则需要将Content-Type设置为"application/json;charset=utf-8"，而不是"application/x-www-form-urlencoded;charset=UTF-8"，以避免出现该错误。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
