[求助] 模拟上传excel文件报错

[复制链接]
发表于 2023-8-30 11:31:42 | 显示全部楼层 |阅读模式
同一个EXCEL文件 在网站上正常提交的时候是没有问题的
利用httphelper 把文件转为byte再上传 时则报错
服务器返回错误:org.apache.tomcat.util.http.fileupload.FileUploadException: Header section has more than 10240 bytes (maybe it is not properly terminated)



[C#] 纯文本查看 复制代码
string filename = "1.xlsx";
        //Byte[] buffer = System.IO.File.ReadAllBytes(Server.MapPath("~/") + "upload/import/" + filename);

        FileStream fs = new FileStream(Server.MapPath("~/") + "upload/import/" + filename, FileMode.Open, FileAccess.Read);
        byte[] buffer = new byte[(int)fs.Length];
        fs.Read(buffer, 0, buffer.Length);
        fs.Close();


        string boundary = "WebKitFormBoundary" + FBA.Logistics.Utils.GenerateRandomNumber(16);// Guid.NewGuid().ToString("N").Substring(16);

        Dictionary<string, object> postdata = new Dictionary<string, object>();

        //FileParameter 是拼接文件流
        FBA.Logistics.FileParameter val = new FBA.Logistics.FileParameter(buffer, filename, "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
        postdata.Add("file", val);
        byte[] formData =FBA.Logistics. Utils.CreateFormData(postdata, boundary);

        string result =System.Text. Encoding.UTF8.GetString(formData);


        var item = new HttpItem()
        {
            Accept = "*/*",
            URL = "http://tms-api.ec-print.cn/order/goodsInfoImport?customerCode=",
            Method = "POST",
            Host = "tms-api.ec-print.cn",
            Referer = "https://oms.szylyn.net/",
            ContentType = "multipart/form-data; boundary=----" + boundary,
            PostDataType = PostDataType.Byte,
            PostdataByte = formData,

        };
        item.Header.Add("Access-Channel-Headers", "ADMIN");
        //item.Header.Add("token", token);
        item.Header.Add("Origin", "http://oms.szylyn.net");

        item.SecurityProtocol = SecurityProtocolType.Ssl3
| SecurityProtocolType.Tls
| SecurityProtocolType.Tls11
| SecurityProtocolType.Tls12;

        HttpHelper helper = new HttpHelper();
        var res = helper.GetHtml(item);
        Response.Write(res.Html);
