问题描述
大家好......我正在尝试使用wcf创建一个产品上传页面。在这个我正在使用服务库。
但是当点击添加按钮时它会显示远程服务器抛出的异常名为
远程服务器返回了意外回应：（413）请求实体太大。
我在这篇文章中实际放置的内容可以帮助我解决这个问题。
添加product.aspx.cs：
hi guys... I am trying to create a page for product upload using wcf. In this i am using service library.
But when click the add button it's showing remote server thrown the exception called
remote server returned an unexpected response: (413) Request Entity Too Large.
What i did actually placing in this post can any body help me to sort out this problem.
add product.aspx.cs:
protected void btnAdd_Click(object sender, EventArgs e)
{
try
{
if (ImageUpload.FileName != "")
{
string path = Server.MapPath("~/images/");
string extension = Path.GetExtension(ImageUpload.PostedFile.FileName);
if (((extension == ".jpg") || ((extension == ".gif") || (extension == ".png"))))
{
FileStream fs = new FileStream(path+ImageUpload.PostedFile.FileName, FileMode.Open,FileAccess.Read);
BinaryReader br = new BinaryReader(fs);
byte[] image = br.ReadBytes((int)fs.Length);
// byte[] raw = new byte[fs.Length];
//fs.Read(raw, 0, Convert.ToInt32(fs.Length));
modeldetails.UploadPhoto = image;
modeldetails.Serviceno = txtServiceNo.Text;
modeldetails.price= long.Parse( txtPrice.Text);
modeldetails.Name=txtName.Text;
modeldetails.ManfacturedDate=DateTime.Parse(txtManfacDate.Text.ToString());
modeldetails.Manfac_Product_ID=Int32.Parse(ddlProctype.SelectedItem.Value);
bool rows = proxy.AddNewProduct(modeldetails);
if (rows)
{
string script = "<script>alert('Data Added Successfully')</script>";
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "Added", script);
}
else
{
string script = "<script>alert('Error Adding Data')</script>";
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "Error", script);
}
}
else
{
StatusLabel.Text = "Only Jpg,gif or Png files are permitted";
}
}
else
{
StatusLabel.Text = "Kindly Select a File.....";
}
}
catch (Exception e1)
{
}
}
Wcf Service Libray：
Wcf Service Libray:
public bool AddNewProduct(Model modeldetails)
{
SqlConnection con = new SqlConnection(Properties.Settings.Default.constr);
con.Open();
SqlCommand insert = new SqlCommand();
insert.CommandType = CommandType.StoredProcedure;
insert.CommandText = "AddProduct";
insert.Connection = con;
SqlParameter prm = insert.Parameters.Add("@Modelname", SqlDbType.NVarChar, 50);
prm.Direction = ParameterDirection.Input;
prm.Value = modeldetails.Name;
prm = insert.Parameters.Add("@Price", SqlDbType.BigInt);
prm.Direction = ParameterDirection.Input;
prm.Value = modeldetails.price;
prm = insert.Parameters.Add("@ManfacDate", SqlDbType.DateTime);
prm.Direction = ParameterDirection.Input;
prm.Value = modeldetails.ManfacturedDate;
prm = insert.Parameters.Add("@ServiceNo", SqlDbType.NVarChar, 50);
prm.Direction = ParameterDirection.Input;
prm.Value = modeldetails.Serviceno;
prm = insert.Parameters.Add("@MprocID", SqlDbType.Int);
prm.Direction = ParameterDirection.Input;
prm.Value = modeldetails.Manfac_Product_ID;
prm = insert.Parameters.Add("@Image", SqlDbType.Image);
prm.Direction = ParameterDirection.Input;
prm.Value = modeldetails.UploadPhoto;
int insertion_done = insert.ExecuteNonQuery();
if (insertion_done == 1)
return true;
else
return false;
}
