ASP. NET MVC Web APIPractical Application in the project

Preface: The following is just the application of people in the project, and the Web API in the data transmission has a variety of ways to achieve, depending on the actual situation depends!

1: Encryption before data transfer, the following is used in Microsoft's own Rijndael class ( for more information about Rijndael , see MSDN ), the three-bit key plus The symmetric algorithm initialization vector, the code is as follows:

simply define an entity class:

public class User

{

public int Id {get; set;}

public string Name {get; set;}

public int Age {get; set;}

}

HttpClient client = new HttpClient ();

Client. baseaddress = new Uri ("http://webapi.test.com");

Analog Transfer data:

User entity = New User ()

{

Id = 1,

Age = 2,

Name = "Hello"

};

String jsonstr = Jsonconvert.serializeobject (entity);

Encrypt the data:

Rijndael r = rijndael.create ();

Initialize the 16-bit key vector:

R.IV = Encoding.UTF8.GetBytes ("Joy accelerates Music,");

32-bit secret key vector:

string key = "070417fa0e95458684116314a2c7cf18"; Guid.NewGuid (). ToString (). Replace ("-", "" ");

R.key = Encoding.UTF8.GetBytes (Key);

Byte[] es = new byte[] {};

using (MemoryStream ms = new MemoryStream ())

{

using (CryptoStream cstream = new CryptoStream (MS, R.createencryptor (), CryptoStreamMode.Write))

{

using (StreamWriter SW = new StreamWriter (Cstream))

{

Sw. WriteLine (JSONSTR);

}

}

Es = Ms. ToArray ();

}

2: transfer data using HttpClient, the code is as follows:

Push data:

Bytearraycontent content = new Bytearraycontent (es);

Task.Factory.StartNew (() =

{

The Requesturl is determined based on the actual configured route:

var res = client. Postasync ("Webapi/getdata", content). Result;

});

return View ();

3: Receive httpclient push data and decrypt it, the code is as follows:

[HttpPost]

Public async task<string> GetData ()

{

byte[] buffer = await Request.Content.ReadAsByteArrayAsync ();

Decrypt:

Rijndael dr = Rijndael.create ();

Initialize the 16-bit key vector:

string key = "070417fa0e95458684116314a2c7cf18";

DR.IV = Encoding.UTF8.GetBytes ("Joy accelerates Music,");

32-bit secret key:

Dr. Key = Encoding.UTF8.GetBytes (key);

String dstr = String. Empty;

using (MemoryStream ms = new MemoryStream (buffer, 0, buffer. Length))

{

using (CryptoStream cstream = new CryptoStream (MS, Dr. CreateDecryptor (), CryptoStreamMode.Read))

{

using (StreamReader sr = new StreamReader (Cstream))

{

Dstr = Sr. ReadLine ();

}

}

}

Deserialization data after decryption succeeds:

User model = jsonconvert.deserializeobject<user> (DSTR);

//........ Other processing

return "OK";

}
