flask将模型部署为web service 步骤一：将图片转为base64编码 http://tool.chinaz.com/tools/imgtobase/ 步骤二：运行代码 import json import base64 import uuid import os import cv2 from flask import Flask, request from mmdet.apis import inference_detector, init_detector # 模型初始化 model = init_detector(c. 阅读详情



[WebMethod]

 public void MsgBackAddOrModi(int InputPersonID, string Isyscode, string CreatDate, string CusClass, string CusID, string Photo0, string Photo1, string Photo2, string Photo3)

{

string dbcon = ConfigurationManager.ConnectionStrings["AucmaZDCoon"].ToString();

            SqlConnection conn = new SqlConnection(dbcon);

            DataSet ds = null;

 try

            {

                if (conn.State == ConnectionState.Closed)

                {

                    conn.Open();

                }



                string sqlproc = "spMsgBackAddOrModi";

                SqlCommand cmd = new SqlCommand(sqlproc, conn);

                cmd.CommandType = CommandType.StoredProcedure;

                cmd.Parameters.Add("@PersonID", SqlDbType.Int, 4);

                cmd.Parameters["@PersonID"].Direction = ParameterDirection.Input;

                cmd.Parameters["@PersonID"].Value = InputPersonID;

……

//执行存储

SqlDataAdapter da = new SqlDataAdapter(cmd);

                ds = new DataSet();

                da.Fill(ds);

int MsgBackID = Convert.ToInt32(ds.Tables[0].Rows[0][2].ToString());

 byte[] arr = Convert.FromBase64String(photo0);

MemoryStream ms = new MemoryStream(arr);

                Bitmap bmp = new Bitmap(ms);

string filename = DateTime.Now.ToString("yyyyMMddHHmmss") + Guid.NewGuid().ToString().Substring(0, 5) + ".jpg";

bmp.Save("F:\\Pic\\" + filename, System.Drawing.Imaging.ImageFormat.Jpeg);

string url = "http://localhost/WebTest/pic/" + filename;

//执行保存图片路径跟主表ID的存储

Context.Response.Charset = "GB2312"; //设置字符集类型  

                    Context.Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");

                    Context.Response.Write(“成功”);

}

现在是直接访问此webservice页面http://localhost/WebTest/ZDMsgBackInfoWS.asmx，此MsgBackAddOrModi方法，不会报错，会返回成功，写了一个test页面， temp.ZDMsgBackInfoWSSoapClient a = new temp.ZDMsgBackInfoWSSoapClient();
a.MsgBackAddOrModi(8023, "", "2015-12-14", "1", "1", Convert.ToBase64String(arr), null, null, null);
就会报错，提示：【从网络接收的xml存在问题。有关详细问题，请参见内部异常】
跟踪之后，发现异常是【根级别上的数据无效。行 1,位置 1】，但是发布后，F5直接运行该webservice页面调用方法就不会报错，测试页面引用就会报错……求解答
