我一直试图找出如何从Angularjs前端的一个HTTP请求表单中解析PDF文档和JSON数据。请求有效负载为

HTTP请求

内容处置:表单数据;name =“文件”; filename =“ Parent Handbook.pdf”内容类型:application / pdf

内容处置:表单数据;name =“ doc”

{“ title”:“ test”,“ cat”:“ test cat”,“ date”:20142323}

“文件”是pdf,“ doc”是我要解析的json数据。

我的处理程序可以很好地解析和保存文件,但无法从Json中获取任何内容。有任何想法吗?

func (s *Server) PostFileHandler(w http.ResponseWriter, r *http.Request) {
    const _24K = (1 << 20) * 24
    err := r.ParseMultipartForm(_24K)
    if err != nil {
        http.Error(w, err.Error(), http.StatusInternalServerError)
        return
    }
    doc := Doc{}
    jsonDecoder := json.NewDecoder(r.Body)
    fmt.Println(r.Body)
    err = jsonDecoder.Decode(&doc)
    if err != nil {
        fmt.Println(err.Error())
    }
    fmt.Println(doc.Title, doc.Url, doc.Cat, doc.Date)
    doc.Id = len(docs) + 1
    err = s.db.Insert(&doc)
    checkErr(err, "Insert failed")

    // files := m.File["myFile"]
    for _, fheaders := range r.MultipartForm.File {
        for _, hdr := range fheaders {
            var infile multipart.File
            infile, err = hdr.Open()
            // defer infile.Close()
            if err != nil {
                http.Error(w, err.Error(), http.StatusInternalServerError)
                return
            }
            doc.Url = hdr.Filename
            fmt.Println(hdr.Filename)
            var outfile *os.File
            outfile, err = os.Create("./docs/" + hdr.Filename)
            // defer outfile.Close()
            if err != nil {
                http.Error(w, err.Error(), http.StatusInternalServerError)
                return
            }
            _, err = io.Copy(outfile, infile)
            if err != nil {
                http.Error(w, err.Error(), http.StatusInternalServerError)
                return
            }

        }
    }
    s.Ren.JSON(w, http.StatusOK, &doc)
    // http.Error(w, "hit file server", http.StatusOK)
}
