Does websocket of this lib support windows 7

Does websocket of this lib support windows 7 as very many users still use windows 7

[garethsb]

Yes.

[developernew123]

ok , and is there any errors on windows 10 as I tried a simple c++ websocket lib it was good although it hadn't a message handler but I didn't need this feature
the problem is that it worked well on windows 7 and 8 but on windows 10 I got an error in cmd :
Error : url size limit reached then the program crashes , I wish this doesn't happen with this library

C++ REST SDK enables implementing websocket clients, see https://github.com/Microsoft/cpprestsdk/wiki/Web-Socket. There's an open issue to add support for implementing websocket server, see #358.

The current C++ REST SDK cross-platform Web Socket code is built on top of the Websocket++ open source library.

I tried to use it after building statically but I still nedd a dll file and the program crashes when I try to connect to the server

I'm trying to connect to chrome remote debugger on port 4789 so I launch chrome with the needed args then send curl request to localhost:port/json to get ws urls of the pages to connect to them

for example I got this :
[ {
"description": "",
"devtoolsFrontendUrl": "/devtools/inspector.html?ws=localhost:4789/devtools/page/(155CF001CDD9DB93AEADF79728040F11)",
"faviconUrl": "https://www.google.com.eg/favicon.ico",
"id": "(155CF001CDD9DB93AEADF79728040F11)",
"title": "علامة تبويب جديدة",
"type": "page",
"url": "chrome://newtab/",
"webSocketDebuggerUrl": "ws://localhost:4789/devtools/page/(155CF001CDD9DB93AEADF79728040F11)"
} ]
I get "ws://localhost:4789/devtools/page/(155CF001CDD9DB93AEADF79728040F11)" and try to connect to it like this :

// I set it string as I recieved and parsed the response from curl as std::string

string url = "urlintext"; TCHAR *wsurl = new wchar_t[wsurl.size()]; MultiByteToWideChar(CP_ACP, 0, url.c_str(), -1, wsurl, url.size()); // connect function doesn't accept anscii websocket_client client; client.connect(wsurl).then([]() {wcout << "connected to chrome" << endl; });;

the program crashes on connecting and the debugger take me to ppltasks.h line 750 which is :
_REPORT_PPLTASK_UNOBSERVED_EXCEPTION();

I want to get rid of this crash and build full statically without any dll

[developernew123]

I put it in try catch statement and I got this :

UTF-16 string is missing low surrogate

[garethsb]

That exception comes from UTF-16 to UTF-8 conversion and indicates invalid UTF-16 data. I suggest you put a breakpoint at https://github.com/Microsoft/cpprestsdk/blob/v2.10.1/Release/src/utilities/asyncrt_utils.cpp#L429 and debug where the invalid data is coming from during the connection process.

[garethsb]

By the way, rather than using std::string and MultiByteToWideChar directly, why not use the facilities of C++ REST SDK, e.g. utility::string_t, utility::conversions::to_string_t(), and the U() macro?

websocket_client client;
client.connect(U("ws://..."));
