Functions

func ExtractMedia

func ExtractMedia(msg *types.WeixinMessage) *types.MessageItem

ExtractMedia finds the first media item by priority: IMAGE > VIDEO > FILE > VOICE. Voice items with a Text field (transcription) are excluded. Falls back to ref_msg media if no direct media is found.

func ExtractText

func ExtractText(msg *types.WeixinMessage) string

ExtractText collects all text from a message's item list, joined with newlines. If a text item has a RefMsg, the quoted message summary is prepended.

func FormatQuotedMessage

func FormatQuotedMessage(refMsg *types.RefMsg) string

FormatQuotedMessage formats a RefMsg as a human-readable quoted message indicator. If the ref has a Title, it returns "[引用: title]". Otherwise, it inspects the referenced message item for media type.

func HasMedia

func HasMedia(item *types.MessageItem) bool

HasMedia returns true if the message item contains any media content (image, video, file, or voice with CDN media).

func MediaCDNInfo

func MediaCDNInfo(item *types.MessageItem) *types.CDNMedia

MediaCDNInfo extracts the CDNMedia from the first media-bearing field found in a message item. Returns nil if no media is present.
