Dopo aver effettuato il caricamento dei dati sul mio Rails Server tramite C# (controllareper sapere di cosa sto parlando), sto provando a caricare un file sullo stesso server, insieme a altri dati.Carica file tramite C# utilizzando JSON request e RestSharp
In Ruby, sono in grado di fare questo con il codice:
require 'HTTMultiParty'
class ReceiptCreate
include HTTMultiParty
# Log to file
# debug_output File.new("httparty1.log", "w+")
base_uri "localhost:3000"
format :json
headers "Accept" => "application/json"
def initialize
end
def post(machine_serial,filepath,tag_number,token)
options = { body:
{receipt:
{tag_number:tag_number,
receipt_file: File.new(filepath),
ispaperduplicate:0
},
machine:
{serial_number: machine_serial,
safe_token: token
}
}
}
self.class.post('/receipts', options)
end
end
receipt = ReceiptCreate.new()
filename1 = "C:\\filename1.pdf"
filename2 = "C:\\filename2.pdf"
response=receipt.post("2803433",filename2,"p94tt7w","123")
puts response
una quando ho ispezionare i parametri sul server rotaie vedo
Parameters: {"receipt"=>{"tag_number"=>"p94tt7w", "receipt_file"=>#<ActionDispatch::Http::UploadedFile:0x4183ea8 @original_filename="Invoice.pdf", @content_type="application/octet-stream", @headers="Content-Disposition: form-data; name=\"receipt[receipt_file]\"; filename=\"Invoice.pdf\"\r\nContent-Length: 11653\r\nContent-Type: application/octet-stream\r\nContent-Transfer-Encoding: binary\r\n", @tempfile=#<File:C:/Users/diogo/AppData/Local/Temp/RackMultipart20130103-18168-efiqia>>, "ispaperduplicate"=>"0"}, "machine"=>{"serial_number"=>"2803433", "safe_token"=>"123"}}
Ma se provo a fare il stessa cosa con il mio codice C# sotto
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using RestSharp;
using System.Web.Script.Serialization;
using System.IO;
namespace RonRestClient
{
class templateRequest
{
public Receipt receipt;
public class Receipt
{
public float total;
public String tag_number;
public bool ispaperduplicate = true;
public byte[] receipt_file;
public Receipt(float total, String tagnr, string filepath)
{
this.total = total;
this.tag_number = tagnr;
this.receipt_file = File.ReadAllBytes(filepath);
}
};
public Machine machine;
public class Machine
{
public String serial_number;
public String safe_token;
public Machine(String machinenr, String safe_token)
{
this.serial_number = machinenr;
this.safe_token = safe_token;
}
};
}
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
string path = @"C:\filename2.pdf";
string tagnr = "p94tt7w";
string machinenr = "2803433";
string safe_token = "123";
float total = 100;
templateRequest req = new templateRequest();
req.receipt = new templateRequest.Receipt(total, tagnr, path);
req.machine = new templateRequest.Machine(machinenr, safe_token);
//string json_body = JsonConvert.SerializeObject(req);
//string json_body = new JavaScriptSerializer().Serialize(req);
//var json_body = "{\"receipt\" : {\"total\":"+total+", \"tag_number\":\""+tagnr+"\",\"ispaperduplicate\":true},\"machine\":{\"serial_number\": \""+machinenr+"\",\"safe_token\": \""+safe_token+"\"}}";
var client = new RestClient("http://localhost:3000/receipts");
var request = new RestRequest(Method.POST);
//set request Body
request.AddHeader("Content-type", "application/json");
request.AddHeader("Accept", "application/json");
request.RequestFormat = DataFormat.Json;
request.AddBody(req);
//request.AddParameter("application/json", json_body, ParameterType.RequestBody);
// easily add HTTP Headers
// add files to upload (works with compatible verbs)
//request.AddFile("receipt/receipt_file",path);
// execute the request
IRestResponse response = client.Execute(request);
var content = response.Content; // raw content as string
if(response.ErrorMessage !="") content += response.ErrorMessage;
response_box.Text = content;
}
}
}
ottengo questo
012.Parameters: {"receipt"=>{"total"=>100, "tag_number"=>"p94tt7w", "ispaperduplicate"=>true, "receipt_file"=>[37, 80, [n3...nX], 10]}, "machine"=>{"serial_number"=>"2803433", "safe_token"=>"123"}}
Questo sembra significare sostanzialmente che Restsharp pensa solo che il mio file sia solo un altro campo.
RestSharp sembra avere un metodo per aggiungere i file request.AddFile("receipt/receipt_file",path);, e credo che questo dovrebbe essere probabilmente la strada da percorrere ... ma quando cerco solo e aggiungere il file, viene visualizzato un messaggio di errore che dice:
Questa proprietà non può essere impostata dopo l'inizio della scrittura.
Devo impostare separatamente ciascun attributo del file?
EDIT
Nel frattempo ho trovato questo post, cambiato il mio codice a:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using RestSharp;
using System.Web.Script.Serialization;
using System.IO;
using System.Net;
namespace RonRestClient
{
class templateRequest
{
public Receipt receipt;
public class Receipt
{
//public float total;
public String tag_number;
public bool ispaperduplicate = true;
//public byte[] receipt_file;
public Receipt(String tagnr)
{
//this.total = total;
this.tag_number = tagnr;
// this.receipt_file = File.ReadAllBytes(filepath);
}
};
public Machine machine;
public class Machine
{
public String serial_number;
public String safe_token;
public Machine(String machinenr, String safe_token)
{
this.serial_number = machinenr;
this.safe_token = safe_token;
}
};
}
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
string path = @"C:\filename2.pdf";
string tagnr = "p94tt7w";
string machinenr = "2803433";
string safe_token = "123";
float total = 100;
templateRequest req = new templateRequest();
req.receipt = new templateRequest.Receipt(tagnr);
req.machine = new templateRequest.Machine(machinenr, safe_token);
var request = new RestRequest("/receipts",Method.POST);
request.AddParameter("receipt[total]", total);
request.AddParameter("receipt[tag_number]", tagnr);
request.AddParameter("machine[serial_number]", machinenr);
request.AddParameter("machine[safe_token]", safe_token);
request.AddFile("receipt[receipt_file]", File.ReadAllBytes(path), "Invoice.pdf", "application/octet-stream");
// Add HTTP Headers
request.AddHeader("Content-type", "application/json");
request.AddHeader("Accept", "application/json");
request.RequestFormat = DataFormat.Json;
//set request Body
//request.AddBody(req);
// execute the request
//calling server with restClient
RestClient restClient = new RestClient("http://localhost:3000");
restClient.ExecuteAsync(request, (response) =>
{
if (response.StatusCode == HttpStatusCode.OK)
{
//upload successfull
MessageBox.Show("Upload completed succesfully...\n" + response.Content);
}
else
{
//error ocured during upload
MessageBox.Show(response.StatusCode + "\n" + response.StatusDescription);
}
});
}
}
}
e ora sto ricevendo i parametri:
Parameters: {"receipt"=>{"total"=>"100", "tag_number"=>"p94tt7w", "receipt_file"=>#<ActionDispatch::Http::UploadedFile:0x3db42d8 @original_filename="Invoice.pdf", @content_type="application/octet-stream", @headers="Content-Disposition: form-data; name=\"receipt[receipt_file]\"; filename=\"Invoice.pdf\"\r\nContent-Type: application/octet-stream\r\n", @tempfile=#<File:C:/Users/diogo/AppData/Local/Temp/RackMultipart20130103-18168-9mbt3h>>}, "machine"=>{"serial_number"=>"2803433", "safe_token"=>"123"}}
Insieme con un HTTP 422 - Unprocessable Errore entità.
Se devo confrontare questi parametri con quelli che ho a che fare con il codice ruby, ora l'unica differenza sembra essere che questo ultimo messaggio non ha i campi Content-length e Content-Transfer-Encoding.
Avete qualche idea su come aggiungere gli attributi?
