No error will be reported for illegal JSON requests

[lingcoder]

Go version

go version go1.23.3 windows/amd64

GoFrame version

v2.8.3

Can this bug be reproduced with the latest release?

Option Yes

What did you do?

使用默认的规范路由写法定义controller层出参入参，默认应该是application/json 请求。
前端传递了非法的JSON。gf没有任何错误提醒。

What did you see happen?

request := g.RequestFromCtx(ctx)
fmt.Println(request.GetBodyString())

What did you expect to see?

应该提示参数格式不对吧？

@lingcoder 唔，因吹斯汀，ghttp.Server在处理Body的解析的时候并没有判断提交的ContentType类型值，并且识别JSON格式的时候也不太严谨，同时忽略了解析错误：

gf/net/ghttp/ghttp_request_param.go

Line 228 in e1fa990

func (r *Request) parseBody() {

这块有很大的改进空间：

1. parseBody应当返回error，并且针对其他内部解析方法parseQuery/parseForm也应当返回error，不应当忽略，也不应当panic。
2. 在针对Body内容进行解析时：
   • 优先识别ContentType提交的类型值，如果是JSON格式并且JSON解析失败，应当返回报错。
   • 如果没有ContentType提交，那么保留现有的格式判断，并可以忽略格式解析错误。
3. 解析错误应当SetError到当前的ghttp.Request中，以便更上层能捕获执行自定义错误处理。

@lingcoder Well, because of Sting, ghttp.Server did not judge the submitted ContentType type value when processing Body parsing, and was not very strict when recognizing the JSON format, and ignored parsing errors. : https://g ithub.com/gogf/gf/blob/e1fa99013a02cd76c5297a896a83a2ba74a77c2a/net/ghttp/ghttp_request_param.go#L228

There is a lot of room for improvement in this area:

1. parseBody should return error, and other internal parsing methods parseQuery/parseForm should also return error, which should not be ignored or panic.
2. When parsing the content of Body:
   • Prioritize the identification of the type value submitted by ContentType. If it is in JSON format and JSON parsing fails, an error should be returned.
   • If no ContentType is submitted, the existing format judgment is retained and format parsing errors can be ignored.
3. Parsing errors should SetError to the current ghttp.Request so that the upper layer can capture and perform custom error handling.
