示例1: httpVersionStaticPreamble

// "The HTTP version MUST be at least 1.1."
static inline bool headerHasValidHTTPVersion(StringView httpStatusLine)
{
const char* httpVersionStaticPreambleLiteral = "HTTP/";
StringView httpVersionStaticPreamble(reinterpret_cast<const LChar*>(httpVersionStaticPreambleLiteral), strlen(httpVersionStaticPreambleLiteral));
if (!httpStatusLine.startsWith(httpVersionStaticPreamble))
return false;
// Check that there is a version number which should be at least three characters after "HTTP/"
unsigned preambleLength = httpVersionStaticPreamble.length();
if (httpStatusLine.length() < preambleLength + 3)
return false;
auto dotPosition = httpStatusLine.find('.', preambleLength);
if (dotPosition == notFound)
return false;
