ssl - Using setWebhook from Qt for a Telegram bot -

-

im developing telegram bot using qt c++, , i'm having problems trying set webhook.

ssl server

first of all, i've created ssl server using qtcpserver , qsslsocket. explanations can found in qsslsocket doc. also, generated self-signed certificate telegram doc explains here, using command:

openssl req -newkey rsa:2048 -sha256 -nodes -keyout yourprivate.key -x509 -days 365 -out yourpublic.pem -subj "/c=us/st=new york/l=brooklyn/o=example brooklyn company/cn=yourdomain.example"

the result pair of files, private.key file , public.pem file. so, used them in qsslsockets secure connection.

the result of ssl server capable of listen , accept connections. when use browser connect ssl server, obtain warning using self-signed certificate (which think normal), can connect server. server, i'm able of read data browser sent. so, think server side good.

request setwebhook

in order perform request setwebhook api method, use qhttpmultipart class create mime multipart request. api method needs url contacted , public certificate. so, use code generate url parameter:

qlist<qhttppart> parameters; qhttppart urlpart; urlpart.setheader(qnetworkrequest::contenttypeheader, qvariant("text/plain")); urlpart.setheader(qnetworkrequest::contentdispositionheader, qvariant("form-data; name=\"url\"")); urlpart.setbody(_url.tolatin1()); parameters.append(urlpart);

and code generate certificate parameter:

qhttppart filepath;     filepath.setheader(qnetworkrequest::contentdispositionheader, qvariant("form-data; name=\"certificate\""));     qfile *file = new qfile(_filepath);     file->open(qiodevice::readonly);     filepath.setbodydevice(file);     file->setparent(this);     parameters.append(filepath);

i receive correct response, message "the webhook set". but, when telegram connects ssl server, ssl handshake doesn't finish in right way (neither encrypted() nor sslerror() signals emitted). think problem way upload public certificate. can see, file qhttppart, doesn't set content-type header because don't know value use. don't know if can problem. use "text/plain" url, don't know use certificate file.

so, don't know problem. even, i'm not sure if file upload or not. using self signed certificate not problem, since documentation indicates valid way. appreciated.

thanks in advance.

i found problem, , content-type. removed content-type of first param, urlpart. , added content-type filepath, using value "application/x-x509-ca-cert". works charm now.

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
