HTTP/Rest クライアントを作成しました。
主な問題は、要求されたデータ内に不明な数字が含まれていることです。私は本当に彼らがどこから来たのか分かりません..
e0b
<html>
<head>
[...]
</body>
</html>
0
最後にe0bと0が表示されます。たとえば、大きなxmlファイルでは、次のようなものがあります。
<sometag id="somei
2000
d"><child>
...
</child></some
2000
tag>
私には再現不可能です。
私のコード:
// read the response status code
boost::asio::streambuf httpStreamBufferResponse;
boost::asio::read_until(httpSocket, httpStreamBufferResponse, "\r\n");
// check status code and validate
istream httpResponseIStream(&httpStreamBufferResponse);
// temp var for version
string sHttpVersion;
httpResponseIStream >> sHttpVersion;
// temp var for status code
unsigned int uiStatusCode;
httpResponseIStream >> uiStatusCode;
// fetch status message and switch it
string sStatusMessage;
getline(httpResponseIStream, sStatusMessage);
if(!httpResponseIStream || sHttpVersion.substr(0, 5) != "HTTP/"){
new Note(eNotesType(ERROR), "Request Interrupt", "Invalid Request Response");
Log::write("ERROR: Request Interrupt: Invalid Request Response");
}
// != 200 even means that something is not OK
if(uiStatusCode != 200){
this -> sHttpStatusCode = uiStatusCode;
new Note(eNotesType(WARNING), "Request Response "
+ boost::lexical_cast<string>(uiStatusCode), httpErrorToString.at(uiStatusCode));
Log::write("WARNING: Request Response "
+ boost::lexical_cast<string>(uiStatusCode) + ": " + httpErrorToString.at(uiStatusCode));
}
// Read the response headers, which are terminated by a blank line.
boost::asio::read_until(httpSocket, httpStreamBufferResponse, "\r\n\r\n");
// Process the response header
stringstream responseSStream;
string responseSHeader;
while (getline( httpResponseIStream, responseSHeader ) && responseSHeader != "\r" ) {
responseSStream << responseSHeader;
}
// store header in member variable
this -> sHttpResponseHeader = sHttpVersion + " " + boost::lexical_cast<string>(uiStatusCode) + " "
+ httpErrorToString.at(uiStatusCode) + "\n" + responseSStream.str();
// read until EOF and writing data to output as we go.
ostringstream responseOSStream;
while(boost::asio::read(httpSocket, httpStreamBufferResponse, boost::asio::transfer_at_least(1), error)){
responseOSStream << &httpStreamBufferResponse;
}
// store content in member variable
this -> sHttpResponseContent = responseOSStream.str();
// if there is no EOF
if(error != boost::asio::error::eof){
new Note(eNotesType(ERROR), "Request Interrupt", "Invalid Response End");
Log::write("ERROR: Request Interrupt: Invalid Response End");
}
// catch not known exceptions properly
} catch (exception& e){
string exceptionMessage = e.what();
new Note(eNotesType(ERROR), "Exception", exceptionMessage);
Log::write("ERROR: Exception: " + exceptionMessage);
}
// log http standby
Log::write("http status: standby");
これがどこから来たのか誰かが何か考えを持っていれば、それは大きな喜びです.. ? !
