I am stuck trying to get some code to build using the POCO libraries. I get the following when I try to build Undefined symbols for architecture x86_64: "Poco::Net::SocketAddress::SocketAddress(std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > const&, unsigned short)", referenced from: ..... ld: symbol(s) not found for architecture x86_64 Now here is the catch: I am linking with -lPocoFoundation -lPocoNet -lPocoUtil What am I missing? (I should say that I am compiling with clang on Mac OS X 10.8.2 I have the same problem. I found change xcode build setting

I want to send some data from a C++ application to a server using a HTTP PUT request. I am using poco library for networking in my application. I am using this code snippet: HTTPClientSession session(_uri.getHost(), _uri.getPort()); HTTPRequest req(HTTPRequest::HTTP_PUT, path, HTTPMessage::HTTP_1_1); Where do I set the content (file) stream when I send the request? Can anyone show me an example using this library? Quoting the online documentation for HTTPClientSession : sendRequest() will return an output stream that can be used to send the request body. After you are done sending the request

Edited to simplify and show my EXACT code. I have the following data that I need to serialize to JSON as well as parse from JSON. string name; std::map<string, string> metaData; I need the JSON to be nested/hierarchical like this: { "name":"john smith" "metadata": { "age":45, "middle_name":"william", }, } Here is my EXACT code: void DeserializeFromJSON(string &jsonString) { // Parse the JSON Poco::JSON::Parser jsonParser; Poco::Dynamic::Var parsedJSON = jsonParser.parse(jsonString); Poco::Dynamic::Var parsedResult = jsonParser.result(); // Extract the JSON Object Poco::DynamicStruct jsonStruct

I am trying to connect to the Echo Test Websocket using the Poco C++ libraries. In order to do so here is my code which should set up the Websocket: HTTPClientSession cs("echo.websocket.org"); HTTPRequest request(HTTPRequest::HTTP_GET, "/ws"); HTTPResponse response; WebSocket* m_psock = new WebSocket(cs, request, response); m_psock->close(); //close immidiately However it does not work: I am getting an error message like this: Poco::Exception: WebSocket Exception: Cannot upgrade to WebSocket connection: Not Found Can anybody help? The 'Not Found' error is the standard HTTP 404 Not Found

I'm trying to make an HTTP Post with HTTP Basic Authentication (cleartext username and password), using POCO. I found an example of a Get and have tried to modify it, but being a rookie I think I've mangled it beyond usefulness. Anyone know how to do this? Yes, I've already seen the other SO question on this: POCO C++ - NET SSL - how to POST HTTPS request , but I can't make sense of how it is trying to implement the username and password part. I also don't understand the use of "x-www-form-urlencoded". Is this required for a Post? I don't have a form. Just want to POST to the server with

According to the Specification in POCO assistant: Initialize the NetSSL library, as well as the underlying OpenSSL libraries, by calling Poco::Crypto::OpenSSLInitializer::initialize(). Should be called before using any class from the NetSSL library. The NetSSL will be initialized automatically, through Poco::Crypto::OpenSSLInitializer instances or similar mechanisms when creating Context or SSLManager instances. However, it is recommended to call initializeSSL() in any case at application startup. When I want to use HTTPSClientSession ,do I have to construct an Application object first? How

Can anyone instruct me on how the Poco C++ JSON works? Previously I've used JsonReader and JsonToken. The Poco C++ library doesn't seem to have corresponding objects. How do I for example use the json parser to create a object name consisting the JSON value at the tag name? Alex EDIT: as of 1.5.2, things were simplified by making DefaultHandler, well ... default (and renaming it to its proper name - ParseHandler . So, if all you need is parsing, no need to explicitly provide the handler anymore: // objects std::string json = "{ \"test\" : { \"property\" : \"value\" } }"; Parser parser; Var
