The first argument is ignored and used for recording .\" the version when the .VS was added, so that the sidebars can be .\" found and removed when they reach a certain age. If another argument .\" is present, then a line break is forced before starting the sidebar. .\" .\" .VE .\" End of vertical sidebar. .\" .\" .DS .\" Begin an indented unfilled display. .\" .\" .DE .\" End of indented unfilled display. .\" .\" .SO ?manpage? .\" Start of list of standard options for a Tk widget.

This current version of the package supports the Oauth 1\&.0 Protocol, as specified in \fIRFC 5849\fR [http://tools\&.ietf\&.org/rfc/rfc5849\&.txt]\&. .SH "TLS SECURITY CONSIDERATIONS" .PP This package uses the \fBTLS\fR package to handle the security for \fBhttps\fR urls and other socket connections\&. .PP Policy decisions like the set of protocols to support and what ciphers to use are not the responsibility of \fBTLS\fR, nor of this package itself however\&. Such decisions are the responsibility of whichever application is using the package, and are likely influenced by the set of servers the application will talk to as well\&. .PP For example, in light of the recent \fIPOODLE attack\fR [http://googleonlinesecurity\&.blogspot\&.co\&.uk/2014/10/this-poodle-bites-exploiting-ssl-30\&.html] discovered by Google many servers will disable support for the SSLv3 protocol\&. To handle this change the applications using \fBTLS\fR must be patched, and not this package, nor \fBTLS\fR itself\&. Such a patch may be as simple as generally activating \fBtls1\fR support, as shown in the example below\&. .CS package require tls tls::init -tls1 1 ;# forcibly activate support for the TLS1 protocol \&.\&.\&. your own application code \&.\&.\&. .CE .SH COMMANDS .TP \fB::oauth::config\fR When this command is invoked without arguments it returns a dictionary containing the current values of all options\&. .TP \fB::oauth::config\fR ?\fIoptions\fR\&.\&.\&.? When invoked with arguments, options followed by their values, it is used to set and query various parameters of application and client, like proxy host and user agent for the HTTP requests\&. The detailed list of options is below: .RS .TP \fB-accesstoken\fR \fIstring\fR This is the user's token\&. .TP \fB-accesstokensecret\fR \fIstring\fR This is the user's secret token\&. .TP \fB-consumerkey\fR \fIstring\fR This is the public token of your app\&. .TP \fB-consumersecret\fR \fIstring\fR This is the private token of your app\&. .TP \fB-debug\fR \fIbool\fR The default value is \fBoff\fR\&. If you change this option to \fBon\fR, the basic signature just created will be printed to stdout, among other debug output\&. .TP \fB-oauthversion\fR \fIversion\fR This is the version of the OAuth protocol to use\&. At the moment only \fB1\&.0\fR is supported, the default\&. .TP \fB-proxyhost\fR \fIhostname\fR You can set up a proxy host for send contact the oauth's api server\&. .TP \fB-proxyport\fR \fIport-number\fR Port number of your proxy\&. .TP \fB-signmethod\fR \fImethod\fR The signature method to use\&. OAuth 1\&.0 only supports \fBHMAC-SHA1\fR, the default\&. .TP \fB-timeout\fR \fImilliseconds\fR Timeout in milliseconds for your query\&. The default value is \fB6000\fR, i\&.e\&. 6 seconds\&. .TP \fB-urlencoding\fR \fIencoding\fR The encoding used for creating the x-url-encoded URLs with \fB::http::formatQuery\fR\&. The default is \fButf-8\fR, as specified by \fIRFC 2718\fR [http://tools\&.ietf\&.org/rfc/rfc2718\&.txt]\&. .RE .TP \fB::oauth::header\fR \fIbaseURL\fR ?\fIpostQuery\fR? This command is the base signature creator\&. With proper settings for various tokens and secrets (See \fB::oauth::config\fR) the result is the base authentication string to send to the server\&. .sp You do not need to call this procedure to create the query because \fB::oauth::query\fR (see below) will do for it for you\&. Doing so is useful for debugging purposes, though\&. .RS .TP url \fIbaseURL\fR This argument is the URI path to the OAuth API server\&. If you plan send a GET query, you should provide a full path\&. .CS HTTP GET ::oauth::header {https://api\&.twitter\&.com/1\&.1/users/lookup\&.json?screen_name=AbiertaMente} .CE .TP url-encoded-string \fIpostQuery\fR When you have to send a header in POST format, you have to put the query string into this argument\&. .CS ::oauth::header {https://api\&.twitter\&.com/1\&.1/friendships/create\&.json} {user_id=158812437&follow=true} .CE .RE .TP \fB::oauth::query\fR \fIbaseURL\fR ?\fIpostQuery\fR? This procedure will use the settings made with \fB::oauth::config\fR to create the basic authentication and then send the command to the server API\&. It takes the same arguments as \fB::oauth::header\fR\&. .sp The returned result will be a list containing 2 elements\&. The first element will be a dictionary containing the HTTP header data response\&. This allows you, for example, to check the X-Rate-Limit from OAuth\&. The second element will be the raw data returned from API server\&. This string is usually a json object which can be further decoded with the functions of package \fBjson\fR, or any other json-parser for Tcl\&. .sp Here is an example of how it would work in Twitter\&. Do not forget to replace the placeholder tokens and keys of the example with your own tokens and keys when trying it out\&. .CS % package require oauth % package require json % oauth::config -consumerkey {your_consumer_key} -consumersecret {your_consumer_key_secret} -accesstoken {your_access_token} -accesstokensecret {your_access_token_secret} % set response [oauth::query https://api\&.twitter\&.com/1\&.1/users/lookup\&.json?screen_name=AbiertaMente] % set jsondata [lindex $response 1] % set data [json::json2dict $jsondata] $ set data [lindex $data 0] % dict for {key val} $data {puts "$key => $val"} id => 158812437 id_str => 158812437 name => Un Librepensador screen_name => AbiertaMente location => Explico mis tuits ahí → description => 160Caracteres para un SMS y contaba mi vida entera sin recortar vocales\&.
