开发GPT知识库功能时，需要上传word文档让知识库向量化，Golang读取word文档功能

import (
    "baliance.com/gooxml/document"
)
func ReadDocxAll(fileName string) (string, error) {
    doc, err := document.Open(fileName)
    if err != nil {
        return "", err
    }
    text := ""

    for _, para := range doc.Paragraphs() {
        //run为每个段落相同格式的文字组成的片段
        for _, run := range para.Runs() {
            text += run.Text()
        }
    }
    return text, nil
}
