我想使用boost :: asio連接到HTTPS服務器。我設法成功地與服務器握手,但我無法設法讓服務器響應我的POST請求。使用boost :: asio連接到HTTPS服務器
這是相關的代碼(我離開了調試和試捕,以節省一些空間):
HTTPSClient::HTTPSClient()
{
ssl::context context(ssl::context::sslv23);
context.set_verify_mode(ssl::verify_peer);
context.set_default_verify_paths();
context.load_verify_file("certificate.pem");
mSSLSocket = new ssl::stream<ip::tcp::socket>(mIOService, context);
}
void HTTPSClient::SendRequest(const ptree &crPTree, const std::string cHost,
const std::string cURI)
{
tcp::resolver resolver(mIOService);
tcp::resolver::query query(cHost, "https");
resolver.async_resolve(query, boost::bind(&HTTPSClient::HandleResolve, this,
placeholders::error, placeholders::iterator, request));
}
void HTTPSClient::HandleResolve(const error_code &crError,
const iterator &criEndpoints, HTTPSRequest &rRequest)
{
async_connect(mSSLSocket->lowest_layer(), criEndpoints,
boost::bind(&HTTPSClient::HandleConnect, this, placeholders::error,
rRequest));
}
void HTTPSClient::HandleConnect(const error_code &crError, HTTPSRequest &rRequest)
{
mSSLSocket->lowest_layer().set_option(ip::tcp::no_delay(true));
mSSLSocket->set_verify_callback(ssl::rfc2818_verification(rRequest.mcHost));
mSSLSocket->handshake(ssl::stream_base::client);
// Write the json into a stringstream
std::ostringstream json;
boost::property_tree::write_json(json, rRequest.mcPTree);
std::string result;
result = json.str();
// Form the request
streambuf request;
std::ostream requestStream(&request);
requestStream << "POST " << rRequest.mcURI << " HTTP/1.1\r\n";
requestStream << "Host: " << rRequest.mcHost << "\r\n";
requestStream << "Accept: application/json\r\n";
requestStream << "Content-Type: application/json; charset=UTF-8\r\n";
requestStream << "Content-Length: " << result.length() << "\r\n";
requestStream << result << "\r\n\r\n";
write(*mSSLSocket, request);
streambuf response;
read_until(*mSSLSocket, response, "\r\n");
std::istream responseStream(&response);
}
read_until掛起,直到它拋出錯誤read_until:文件結束。在此之前的一切都成功了,包括SSL握手(我剛剛纔知道)。
我以前一切都異步完成,直到我開始調試,並開始嘗試追溯到問題,無濟於事。如果有人能在兩個痛苦的調試日子之後幫助我,那將是非常棒的。
編輯 我才意識到這可能是有用的組成頭後requestStream的內容添加:
POST /authenticate HTTP/1.1
Host: <hostname>
Accept: application/json
Content-Type: application/json; charset=UTF-8
Content-Length: 136
{
"username": "vijfhoek",
"password": "test123",
<other json content>
}
也許你忘了將流設置爲二進制和'noskipws' – sehe
