bah.libcurl.mod and bah.libcurlssl.mod questions

| I start learning libcurl.mod and have some questions: When I do: curl.setOptString(CURLOPT_URL, http://www.blhtml.org/BLL.php?blhtml_user=Martin&blhtml_passwd=MyPassword")I can see the session But I can't have the session open, I need to keep login on every request So my first question is can I create a session so I don't need to login on every call? curl.cleanup()when I call cleanup() the connection is already lost! My Second Question is: I can't see but it look like my url request is in plain text so every time I send the url request, someone can sniff my username and password can I somehow cryptate my request with libcurl.mod? When I try build libcurlssl.mod: C:\Wello\MinGW/bin/ar.exe: creating C:/BlitzMax/mod/bah.mod/libcurl.mod/libcurl.debug.mt.win32.x86.a

session->open_channel->remote.packet_size);
My libcurlssl.mod question is: Do I need to have something on the server to use the ssl?in php I can use a function md5 is there a md5 function in BlitzMax? (I know this don't make it more secure, but it's a simple way to just hide the password) (then I can send the password scrambled in plain text and still check the password on the server) If I am forced to send my password on every request, Then I need to cryptate the userinformation/password somehow! Sorry for yet again another universal WRONG and ask to many question in the same post! |

| Hi, just to get you started, here is something that I use: '--------------------------------------- 'A BASIC SESSION EXAMPLE USING LIBCURL '--------------------------------------- 'Create a new session. '-------------------- Local cookie_file:String = "cookie.txt" curl = TCurlEasy.Create() curl.setOptString(CURLOPT_COOKIEJAR, cookie_file) 'Login '------ data = "usercode=" + user + "&password=" + password curl.setOptString(CURLOPT_POSTFIELDS, data) curl.setOptString(CURLOPT_URL, MY_SERVER + "/system/login") curl.perform() 'Interact with the server using previously established session '-------------------------------------------------------------- data = "code=" + mycode + "&name=" + myname + "&age=" + myage curl.setOptString(CURLOPT_POSTFIELDS, data) curl.setOptString(CURLOPT_COOKIE, cookie_file) curl.setOptString(CURLOPT_URL, MY_SERVER + "/document/getperson") curl.perform() 'Logout '------- curl.setOptString(CURLOPT_COOKIE, cookie_file) curl.setOptString(CURLOPT_URL, MY_SERVER + "/system/logout") curl.perform() curl.cleanup() -Henri |

| Thank thee this is the coolest thing I been doing in BlitzMax I am really jumping up and Down here! the cookie working perfectly! |

| My Server is in Denmark and I live on the other side of the Globe! to catch the answer from the server I use: setWriteString() When I use setWriteString() and perform() it lock the application until I get the answer from the server, and if the return package is lost in the void then my application goes into a coma! Is it possible to do a crocodile fix and set a timeout so perform() stop listening for the answer after X amount of seconds? My real question: can I somehow do a perform() without locking the application until he receive the answer from the server? (So I can use a timer to check if the answer has arrived?) |

| Hmm, you could use a thread for your request. In this example here: https://github.com/maxmods/bah.mod/blob/master/libcurl.mod/examples/ex_02.bmx you see how it calls a callback-function - this could be used to stop the thread which executed the remote-request. From the docs (in curlmain.bmx): Returning a non-zero value from this callback will cause libcurl to abort the transfer and return #CURLE_ABORTED_BY_CALLBACK. So after you waited for X seconds, you just set a variable "timeOut = 1" and within your callback function you then do a "return timeOut". Of course this also works _without_ threads, but then your app is blocked until the timeout happens (exception: you do something like "updateMyApp()" within the callback - to have it get updated at least once a second). The other example: https://github.com/maxmods/bah.mod/blob/master/libcurl.mod/examples/ex_05.bmx does a "multi-perform", maybe this is already something useful? bye Ron |

| Thank the Derron perform() still hijack the application! Print "1-----------------------------------------------------" Local res:Int = curl.perform() Print "2-----------------------------------------------------"If I do this simple test: it Print 1 and after 3 to 5 second it Print 2 progressCallback is called to show the progress the ex_05.bmx only for queues: While status = CURLM_CALL_MULTI_PERFORM status = multi.multiPerform(running) WendHe is stuck in this While until he is Done the only option is if I can set a timeout how long time curl.perform() shall wait for the answer from the server! |

| Maybe this can help : https://curl.haxx.se/libcurl/c/CURLOPT_TIMEOUT.html |

| Thank thee that was noobish of me to not find: bah.mod\libcurl.mod\consts.bmx CURLOPT_TIMEOUT |
