726 | <h2 class='title'><a name='OVERVIEW'>Overview</a></h2> |
727 | ||
728 | <p>The CUPS HTTP and IPP APIs provide low-level access to the HTTP and IPP | |
729 | protocols and CUPS scheduler. They are typically used by monitoring and | |
730 | administration programs to perform specific functions not supported by the | |
731 | high-level CUPS API functions.</p> | |
732 | ||
733 | <p>The HTTP APIs use an opaque structure called | |
734 | <a href='#http_t'><code>http_t</code></a> to manage connections to | |
735 | a particular HTTP or IPP server. The | |
736 | <a href='#httpConnectEncrypt'><code>httpConnectEncrypt</code></a> function is | |
737 | used to create an instance of this structure for a particular server. | |
738 | The constant <code>CUPS_HTTP_DEFAULT</code> can be used with all of the | |
739 | <code>cups</code> functions to refer to the default CUPS server - the functions | |
740 | create a per-thread <a href='#http_t'><code>http_t</code></a> as needed.</p> | |
741 | ||
82cc1f9a MS |
742 | <p>The IPP APIs use two opaque structures for requests (messages sent to the CUPS scheduler) and responses (messages sent back to your application from the scheduler). The <a href='#ipp_t'><code>ipp_t</code></a> type holds a complete request or response and is allocated using the <a href='#ippNew'><code>ippNew</code></a> or <a href='#ippNewRequest'><code>ippNewRequest</code></a> functions and freed using the <a href='#ippDelete'><code>ippDelete</code></a> function.</p> |
743 | ||
744 | <p>The second opaque structure is called <a href='#ipp_attribute_t'><code>ipp_attribute_t</code></a> and holds a single IPP attribute which consists of a group tag (<a href='#ippGetGroupTag'><code>ippGetGroupTag</code></a>), a value type tag (<a href='#ippGetValueTag'><code>ippGetValueTag</code></a>), the attribute name (<a href='#ippGetName'><code>ippGetName</code></a>), and 1 or more values (<a href='#ippGetCount'><code>ippGetCount</code></a>, <a href='#ippGetBoolean'><code>ippGetBoolean</code></a>, <a href='#ippGetCollection'><code>ippGetCollection</code></a>, <a href='#ippGetDate'><code>ippGetDate</code></a>, <a href='#ippGetInteger'><code>ippGetInteger</code></a>, <a href='#ippGetRange'><code>ippGetRange</code></a>, <a href='#ippGetResolution'><code>ippGetResolution</code></a>, and <a href='#ippGetString'><code>ippGetString</code></a>). Attributes are added to an <a href='#ipp_t'><code>ipp_t</code></a> pointer using one of the <code>ippAdd</code> functions. For example, use <a href='#ippAddString'><code>ippAddString</code></a> to add the "printer-uri" and "requesting-user-name" string attributes to a request:</p> | |
5a738aea MS |
745 | |
746 | <pre class='example'> | |
747 | <a href='#ipp_t'>ipp_t</a> *request = <a href='#ippNewRequest'>ippNewRequest</a>(IPP_GET_JOBS); | |
748 | ||
82cc1f9a MS |
749 | <a href='#ippAddString'>ippAddString</a>(request, IPP_TAG_OPERATION, IPP_TAG_URI, "printer-uri", |
750 | NULL, "ipp://localhost/printers/"); | |
5a738aea MS |
751 | <a href='#ippAddString'>ippAddString</a>(request, IPP_TAG_OPERATION, IPP_TAG_NAME, "requesting-user-name", |
752 | NULL, cupsUser()); | |
753 | </pre> | |
ef416fc2 | 754 | |
82cc1f9a | 755 | <p>Once you have created an IPP request, use the <code>cups</code> functions to send the request to and read the response from the server. For example, the <a href='#cupsDoRequest'><code>cupsDoRequest</code></a> function can be used for simple query operations that do not involve files:</p> |
ef416fc2 | 756 | |
5a738aea MS |
757 | <pre class='example'> |
758 | #include <cups/cups.h> | |
ef416fc2 | 759 | |
ef416fc2 | 760 | |
5a738aea MS |
761 | <a href='#ipp_t'>ipp_t</a> *<a name='get_jobs'>get_jobs</a>(void) |
762 | { | |
763 | <a href='#ipp_t'>ipp_t</a> *request = <a href='#ippNewRequest'>ippNewRequest</a>(IPP_GET_JOBS); | |
ef416fc2 | 764 | |
82cc1f9a MS |
765 | <a href='#ippAddString'>ippAddString</a>(request, IPP_TAG_OPERATION, IPP_TAG_URI, "printer-uri", |
766 | NULL, "ipp://localhost/printers/"); | |
5a738aea MS |
767 | <a href='#ippAddString'>ippAddString</a>(request, IPP_TAG_OPERATION, IPP_TAG_NAME, "requesting-user-name", |
768 | NULL, cupsUser()); | |
769 | ||
770 | return (<a href='#cupsDoRequest'>cupsDoRequest</a>(CUPS_HTTP_DEFAULT, request, "/")); | |
771 | } | |
ef416fc2 | 772 | </pre> |
773 | ||
82cc1f9a | 774 | <p>The <a href='#cupsDoRequest'><code>cupsDoRequest</code></a> function frees the request and returns an IPP response or <code>NULL</code> pointer if the request could not be sent to the server. Once you have a response from the server, you can either use the <a href='#ippFindAttribute'><code>ippFindAttribute</code></a> and <a href='#ippFindNextAttribute'><code>ippFindNextAttribute</code></a> functions to find specific attributes, for example:</p> |
ef416fc2 | 775 | |
5a738aea MS |
776 | <pre class='example'> |
777 | <a href='#ipp_t'>ipp_t</a> *response; | |
778 | <a href='#ipp_attribute_t'>ipp_attribute_t</a> *attr; | |
bc44d920 | 779 | |
5a738aea MS |
780 | attr = <a href='#ippFindAttribute'>ippFindAttribute</a>(response, "printer-state", IPP_TAG_ENUM); |
781 | </pre> | |
782 | ||
82cc1f9a | 783 | <p>You can also walk the list of attributes with a simple <code>for</code> loop like this:</p> |
5a738aea MS |
784 | |
785 | <pre class='example'> | |
786 | <a href='#ipp_t'>ipp_t</a> *response; | |
787 | <a href='#ipp_attribute_t'>ipp_attribute_t</a> *attr; | |
788 | ||
82cc1f9a MS |
789 | for (attr = <a href='#ippFirstAttribute'>ippFirstAttribute</a>(response); attr != NULL; attr = <a href='#ippNextAttribute'>ippNextAttribute</a>(response)) |
790 | if (ippGetName(attr) == NULL) | |
5a738aea MS |
791 | puts("--SEPARATOR--"); |
792 | else | |
82cc1f9a | 793 | puts(ippGetName(attr)); |
5a738aea MS |
794 | </pre> |
795 | ||
82cc1f9a | 796 | <p>The <code>for</code> loop approach is normally used when collecting attributes for multiple objects (jobs, printers, etc.) in a response. Attributes with <code>NULL</code> names indicate a separator between the attributes of each object. For example, the following code will list the jobs returned from our previous <a href='#get_jobs'><code>get_jobs</code></a> example code:</p> |
5a738aea MS |
797 | |
798 | <pre class='example'> | |

857 | ||
858 | <p>To ensure proper encoding, the | |

872 | <h3><a name='SENDING_REQUESTS_WITH_FILES'>Sending Requests with Files</a></h3> | |

874 | <p>The <a href='#cupsDoFileRequest'><code>cupsDoFileRequest</code></a> and | |
875 | <a href='#cupsDoIORequest'><code>cupsDoIORequest</code></a> functions are | |
876 | used for requests involving files. The | |

902 | </pre> | |
903 | ||
904 | <p>The <a href='#cupsDoIORequest'><code>cupsDoIORequest</code></a> function | |
905 | optionally attaches a file to the request and optionally saves a file in the | |
906 | response from the server. It is used when using a pipe for the request | |
907 | attachment or when using a request that returns a file, currently only | |
908 | <code>CUPS_GET_DOCUMENT</code> and <code>CUPS_GET_PPD</code>. For example, | |
909 | the following code will download the PPD file for the sample HP LaserJet | |
910 | printer driver:</p> | |
911 | ||
912 | <pre class='example'> | |
913 | char tempfile[1024]; | |
914 | int tempfd; | |
915 | <a href='#ipp_t'>ipp_t</a> *request = <a href='#ippNewRequest'>ippNewRequest</a>(CUPS_GET_PPD); | |
916 | <a href='#ipp_t'>ipp_t</a> *response; | |
917 | ||
918 | <a href='#ippAddString'>ippAddString</a>(request, IPP_TAG_OPERATION, IPP_TAG_NAME, "ppd-name", | |
919 | NULL, "laserjet.ppd"); | |
920 | ||
921 | tempfd = cupsTempFd(tempfile, sizeof(tempfile)); | |
922 | ||
923 | response = <a href='#cupsDoIORequest'>cupsDoIORequest</a>(CUPS_HTTP_DEFAULT, request, "/", -1, tempfd); | |
924 | </pre> | |
925 | ||
926 | <p>The example passes <code>-1</code> for the input file descriptor to specify | |
927 | that no file is to be attached to the request. The PPD file attached to the | |
928 | response is written to the temporary file descriptor we created using the | |
929 | <code>cupsTempFd</code> function.</p> | |
930 | ||
931 | <h3><a name='ASYNCHRONOUS_REQUEST_PROCESSING'>Asynchronous Request Processing</a></h3> | |
932 | ||
933 | <p>The <a href='#cupsSendRequest'><code>cupsSendRequest</code></a> and | |
934 | <a href='#cupsGetResponse'><code>cupsGetResponse</code></a> support | |

939 | ||
940 | <p>File data is attached to the request using the | |

942 | function, while file data returned from the server is read using the | |
943 | <a href='#cupsReadResponseData'><code>cupsReadResponseData</code></a> | |

976 | <p>The <a href='#cupsSendRequest'><code>cupsSendRequest</code></a> function | |
977 | returns the initial HTTP request status, typically either | |
978 | <code>HTTP_CONTINUE</code> or <code>HTTP_UNAUTHORIZED</code>. The latter status | |
979 | is returned when the request requires authentication of some sort. The | |
980 | <a href='#cupsDoAuthentication'><code>cupsDoAuthentication</code></a> function | |
981 | must be called when your see <code>HTTP_UNAUTHORIZED</code> and the request | |
982 | re-sent. We can add authentication support to our example code by using a | |
