salut les gars… J’essaie de créer une page pour le téléchargement de produits à l’aide de WCF. En cela, j’utilise la bibliothèque de services.
Mais lorsque vous cliquez sur le bouton Ajouter, le serveur distant affiche l’exception appelée
Le serveur distant a renvoyé une réponse inattendue : (413) Request Entity Too Large.
Ce que j’ai fait en plaçant dans ce post, quelqu’un peut-il m’aider à résoudre ce problème.
ajoutez product.aspx.cs :
HTML
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)
{
}
}
Bibliothèque de services WCf :

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;

Salut,
Vous envoyez une très grande entité ou une grande liste d’entités au client
Comment le résoudre.
XML
<system.servicemodel> <bindings> <basichttpbinding> <binding maxreceivedmessagesize="10485760"> <readerquotas ...="" /> </binding> </basichttpbinding> </bindings> </system.servicemodel>
