获取 Content-Type 的小问题

[xmx]

ship/context.go

Lines 410 to 417 in 405a71d

	// ContentType returns the Content-Type of the request without the charset.
	func (c *Context) ContentType() (ct string) {
	ct = c.req.Header.Get(HeaderContentType)
	if index := strings.IndexAny(ct, ";"); index > 0 {
	ct = strings.TrimSpace(ct[:index])
	}
	return
	}

ship/binder.go

Lines 72 to 83 in 405a71d

	// Bind implements the interface Binder, which looks up the registered binder
	// by the request header "Content-Type" and calls it to bind the value dst
	// to req.
	func (mb *MuxBinder) Bind(dst interface{}, req *http.Request) error {
	ct := req.Header.Get("Content-Type")
	if index := strings.IndexAny(ct, ";"); index > 0 {
	ct = strings.TrimSpace(ct[:index])
	}
	if ct == "" {
	return ErrMissingContentType
	}

上面两处代码在获取 Content-Type 时用的是 index > 0，如果测试用例是 ; charset=utf-8，那么切割出的 Content-Type 是 ; charset=utf-8。此时我们期望结果的应该是 空字符串。

故：此处使用 index >= 0 更为妥当
