本文介绍了一种在HTTP客户端中设置请求头的方法，包括固定字段和自定义字段的设置过程。通过对RHTTPHeaders对象的操作，实现了对User-Agent、Accept、Content-Type等标准头部字段及X-Up-Calling-Line-ID等特定字段的设定。

_LIT8(KUserAgent, "SimpleClient 1.0");
_LIT8(KAccept, "*/*");
_LIT8(KMimeType, "text/plain");
_LIT8(KOnline, "X-Online-Host");

_LIT8(KContentLength, "Content-Length"); // Content type sent in a POST request
_LIT8(KContentVendor, "Content-Vendor");
_LIT8(KMsisdn, "X-Up-Calling-Line-ID");
_LIT8(KConnectionType, "Close");

_LIT8(KPragma, "Pragma");
_LIT8(KNoCache, "no-cache");

void SetHeaderL(RHTTPHeaders aHeaders, TInt aHdrField, const TDesC8& aHdrValue)
{
RStringF valStr = iSession.StringPool().OpenFStringL(aHdrValue);
CleanupClosePushL(valStr);
THTTPHdrVal val(valStr);
aHeaders.SetFieldL(iSession.StringPool().StringF(aHdrField,
RHTTPSession::GetTable()), val);
CleanupStack::PopAndDestroy(); // valStr
}

void AddHeaderL(RHTTPHeaders aHeaders, const TDesC8& aHeaderField, const TDesC8& aHeaderValue)
{
RStringPool stringPool = iSession.StringPool();
RStringF valStr = stringPool.OpenFStringL(aHeaderValue);
THTTPHdrVal headerVal(valStr);

RStringF fieldStr = stringPool.OpenFStringL(aHeaderField);

aHeaders.SetFieldL(fieldStr, headerVal);
valStr.Close();
fieldStr.Close();
}

SetHeaderL(hdr, HTTP::EUserAgent, KUserAgent);
SetHeaderL(hdr, HTTP::EAccept, KAccept);
SetHeaderL(hdr, HTTP::EContentType, KMimeType);

AddHeaderL(headers, KOnline(), ip);
AddHeaderL(headers, KPragma(), KNoCache());
