send utf-8 string http request

[Mullin Yu]

I want to submit a utf-8 xml request to a servlet by the following coding.
it seesm that the servlet can't recognize it correctly.

can i just using string postData = "..... utf-8 data" and then save the
files at utf-8 encoded at the vs.net ide?

or if i use string, vs.net ide will conside it to be utf-16???

UTF8Encoding encoding = new UTF8Encoding();


string postData = "<?xml version=\"1.0\" encoding=\"utf-8\"?>" +

"<SOAP-ENV:Envelope xmlns:SOAP-ENV=\"urn:schem as-xmlsoap-org:envelope\"> " +

"<SOAP-ENV:Header>" +

"<SOAPActionVer sion>1.5.5</SOAPActionVersi on></SOAP-ENV:Header>" +

"<SOAP-ENV:Body>" +

"<cmEDMSCustome rContactPage transactionType =\"UPDT\">" +

"<cmEDMSCustome rContactPageSer vice>" +

"<cmEDMSCustome rContactPageHea der PageReadSW=\"fa lse\"
CustomerContact ID=\"8210710493 \"></cmEDMSCustomerC ontactPageHeade r>" +

"<cmEDMSCustome rContactPageDet ails>" +

"<LogEntry> " +

"<LogEntryHeade r CustomerContact ID=\"8210710493 \">" +

"</LogEntryHeader> " +

"<LogEntryR ow rowAction=\"ADD \" CustomerContact ID=\"8210710493 \" LogEntry=\"
utf-8 characters \">" +

"</LogEntryRow>" +

"</LogEntry>" +

"</cmEDMSCustomerC ontactPageDetai ls>" +

"</cmEDMSCustomerC ontactPageServi ce>" +

"</cmEDMSCustomerC ontactPage>" +

"</SOAP-ENV:Body >" +

"</SOAP-ENV:Envelope>";

Console.WriteLi ne(postData);


byte[] data = encoding.GetByt es(postData);


// Prepare web request...

HttpWebRequest myRequest =
(HttpWebRequest )WebRequest.Cre ate(http://172.18.2.1:7520/server);


myRequest.Metho d = "POST";

myRequest.Conte ntType="text/xml";

myRequest.Conte ntLength = data.Length;

myRequest.SendC hunked = true;

myRequest.Trans ferEncoding = "UTF8";


myRequest.Crede ntials = new NetworkCredenti al("CDX", "pwd");

Stream newStream=myReq uest.GetRequest Stream();

// Send the data.

newStream.Write (data,0,data.Le ngth);

newStream.Close ();

There's no need to create a new UTF8Encoding - just use Encoding.UTF8.

The rest of your code looks almost correct though. All you need is to
change your content type so it's "text/xml; encoding=UTF-8" so that the
servlet can work out what you've sent it in. It should then be fine.

Actually, there is. Encoding.UTF8 adds a BOM, which you definitely don't
want when posting data.

What's the exact error?

I don't see any evidence of that when using Encoding.UTF8.G etBytes (as
the OP used):

using System;
using System.Text;

class Test
{
static void Main()
{
Console.WriteLi ne (Encoding.UTF8. GetBytes("x").L ength);
}
}

prints 1, rather than 4 which it would print if a BOM were being used.

It uses a BOM if you create a StreamWriter with it though.

Even if you were to want to use a version of UTF8Encoding which didn't
use a BOM, I'd make it a static readonly member of another class rather
than creating a new instance every time you go through the routine.

Re: send utf-8 string http request

the utf8 chinese character became rubblish at oracle db, but it's ok for the
java program, so that i suspect it's due to my limited knowledge of using
class and method in .net.

how about reading from a utf-8 file, i can read it, but it seems having 6
bytes of byte order marks. am i right?

thanks!

You need to find out exactly where the characters became "rubbish". The
way to do that is to output them (as unicode numbers rather than
glyphs) at various different points, and check where they go wrong.

No, I believe there should only be 3 bytes of BOM: 0xef 0xbb 0xbf.

Yeah, got that mixed up.

Sure, but tell it to the original author ;->
