As a new company is getting started with MVC and other things. So I picked up a lot of things again.
Some time ago, I was asked to write a method for connecting to a third-party company push. Push the data post through the URL provided by the other party.
I moved the url to web. config.
Copy codeThe Code is as follows:
<Add key = "urlStrings" value = "urladdress"/>
In the. CS File
Copy codeThe Code is as follows:
Private string postString = System. Configuration. ConfigurationManager. receivettings ["urlStrings"]. ToString ();
Because I want to transfer the data in xml format, we need to package the data and then send the data through the HttpWebRequest request.
Copy codeThe Code is as follows:
String body = string. Format (@ "<? Xml version = "" 1.0 "" encoding = "" UTF-8 ""?>
<Body>
<ValidId> {0} </ValidId>
<OrderId> {1} </OrderId>
<Count> {2} </Count>
<ValidTime >{3 }</ValidTime>
<Remark/>
</Body> ", consumption. id, consumption. order. agentOrderId, consumption. count, consumption. createTime. dateTimeToDateString ("yyyy-MM-dd HH: mm: ss "));
String request = BuildRequest (body );
HttpWebRequest hwr = (HttpWebRequest) WebRequest. Create (postString );
Hwr. Method = "POST ";
Hwr. Headers. Add ("X-Auth-Token", HttpUtility. UrlEncode ("openstack "));
Hwr. ContentType = "application/json ";
// Hwr. Accept = "application/xml ";
Hwr. AllowAutoRedirect = true;
Byte [] dates = Encoding. UTF8.GetBytes (request );
Int count = dates. Length;
// Stream newStream = hwr. GetRequestStream ();
MemoryStream newStream = new MemoryStream ();
Try
{
Log. Add ("START request ");
NewStream. Write (dates, 0, dates. Length );
Hwr. ContentLength = newStream. Length;
Stream requestStream = hwr. GetRequestStream ();
NewStream. Position = 0L;
NewStream. CopyTo (requestStream );
NewStream. Close ();
RequestStream. Close ();
It is worth noting that at the beginning, the earliest MemoryStream used Stream. However, Stream data streams may report errors inexplicably. Stream Data Streams cannot perform length search.
Later, I found a solution through online search. I used MemoryStream to temporarily represent Stream. Finally, I put some search operations on Stream on MemoryStream. Finally, I used CopyTo () of MemoryStream () method To import data into Stream data streams.
The last step is to receive data, which is simpler.
Copy codeThe Code is as follows:
HttpWebResponse hwResponse = (HttpWebResponse) hwr. GetResponse ();
Stream stream = null;
Stream = hwResponse. GetResponseStream ();
StreamReader reader = new StreamReader (stream, System. Text. Encoding. Default, true );
String file = reader. ReadToEnd ();
UTF8Encoding UTF = new UTF8Encoding ();
Byte [] Bytes = UTF. GetBytes (file );
File = UTF. GetString (Bytes );
This place has a conversion to data encoding, I am converting to UTF-8 encoding.
Finally, I am processing the received data. Because I am receiving xml text data, I still have some processing operations to facilitate subsequent operations.
Copy codeThe Code is as follows:
HttpWebResponse hwResponse = (HttpWebResponse) hwr. GetResponse ();
Stream stream = null;
Stream = hwResponse. GetResponseStream ();
StreamReader reader = new StreamReader (stream, System. Text. Encoding. Default, true );
String file = reader. ReadToEnd ();
UTF8Encoding UTF = new UTF8Encoding ();
Byte [] Bytes = UTF. GetBytes (file );
File = UTF. GetString (Bytes );
String strBody = TCodeServiceCrypt. Decrypt3DESFromBase64 (GetElementValue (doc. Element ("Response"). Element ("Body"), UserFunc. SecretKey );
XDocument xBody = XDocument. Parse (strBody );
String userId = GetElementValue (xBody. Element ("Body"). Element ("UseId "));
This is some of the applications I used this time.
I am a newbie. Please advise me more.
