Zvandaisafarira nezve IMAP
Protocol yakatangwa muna 1986. Zvinhu zvakawanda zvinotsanangurwa muchiyero hazvichina basa nhasi. Semuenzaniso, iyo protocol inogona kudzorera nhamba yemitsara yetsamba uye checksums -Kushanda uku hakushandiswe mune zvemazuva ano email vatengi.
Rimwe dambudziko rine chekuita nekushandiswa kwemotokari. Ne IMAP, maemail anochengetwa pane sevha uye nguva nenguva anowiriraniswa nevatengi vemunharaunda. Kana nekuda kwechimwe chikonzero kopi pamudziyo wemushandisi ikashatiswa, tsamba dzese dzinofanirwa kuwiriraniswa zvakare. Munyika yanhasi, kana zviuru zvemafoni efoni anogona kubatana kune server, nzira iyi inotungamira mukuwedzera kushandiswa kwetraffic uye komputa zviwanikwa.
Matambudziko anomuka kwete chete neprotocol pachayo, asiwo nevatengi veemail vanoshanda nayo. Kubva pakusikwa kwayo, IMAP yanga iri pasi pekudzokororwa kwakasiyana kakawanda - iyo yazvino vhezheni nhasi IMAP4. Panguva imwecheteyo, kune zvakawanda zvingasarudzwa zvekuwedzera kune iyo - pane network makumi mapfumbamwe maRFC ane akawedzera. Imwe yeazvino ndeye , yakaunzwa muna 2019.
Panguva imwecheteyo, makambani mazhinji anopa avo ega mhinduro dzinofanirwa kurerutsa kushanda neIMAP kana kutoitsiva: , , . Mhedzisiro ndeyekuti vatengi veemail varipo vanongotsigira zvimwe zvezvinhu zviripo. Kusiyana kwakadaro kunotungamira mukugovaniswa kwemusika.
"Uyezve, mutengi wemazuva ano weemail haafanire kutumira mameseji chete, asi anokwanisa kushanda nevanobata uye kuwiriranisa nekarenda," anodaro Sergei Belkin, mukuru webudiriro kuIaaS mupi. . - Nhasi, yechitatu-bato mapuroteni senge , ΠΈ . Iyi nzira inokanganisa kugadziridzwa kwemafirewall mumakambani network uye inovhura mavector matsva ekurwisa cyber. "
JMAP yakagadzirirwa kugadzirisa aya matambudziko. Iyo iri kuvandudzwa neFastMail nyanzvi pasi pekutungamirwa neInternet Engineering Task Force (IETF). Iyo protocol inomhanya pamusoro peHTTPS, inoshandisa JSON (nekuda kwechikonzero ichi haikodzeri chete kuchinjanisa mameseji emagetsi, asiwo nekugadzirisa akati wandei mabasa ari mugore) uye inorerutsa sangano rekushanda netsamba munharembozha. Pamusoro pekugadzirisa mavara, JMAP inopawo kugona kubatanidza mawedzero ekushanda nevanobatika uye kalendari inoronga.
Zvimiro zveprotocol itsva
JMAP iri (isina state) uye haidi kubatana zvachose kune mail server. Iyi ficha inorerutsa basa mune isina kugadzikana nharembozha uye inochengetedza bhatiri simba pamidziyo.
Iyo email muJMAP inomiririrwa mune JSON chimiro fomati. Iine ruzivo rwese kubva mumeseji (Internet Message Format), iyo inogona kudiwa neemail application. Sekureva kwevagadziri, nzira iyi inofanirwa kurerutsa kusikwa kwevatengi, sezvo kugadzirisa zvinogona kunetsa (zvakabatana ne , kuverenga misoro uye encoding) sevha inopindura.
Mutengi anoshandisa iyo API kubata server. Kuti uite izvi, inogadzira yakavimbiswa POST chikumbiro, izvo zvimiro zvinotsanangurwa muchikamu cheJMAP chikamu. Chikumbiro chiri mukushandisa/json fomati uye ine chinhu chimwe chekukumbira cheJSON. Sevha zvakare inogadzira chinhu chimwe chekupindura.

Iyo yakazara JMAP yakatarwa nemuenzaniso mashandisirwo inogona kuwanikwa pa project. Ikoko vanyori vakatumirawo tsananguro yezvakatemwa zve ΠΈ - vane chinangwa chekushanda nemakarenda uye mazita ekusangana.

Matarisiro
Kunyangwe chokwadi chekuti basa pachiyero hachisati chapedzwa zviri pamutemo, chiri kutoitwa munzvimbo dzekugadzira. Semuenzaniso, vagadziri veiyo yakavhurika mail server yakashandisa JMAP vhezheni yayo. Vagadziri kubva FastMail server framework yeiyo protocol nyowani muPerl, uye vanyori veJMAP vakaratidzwa .
Tinogona kutarisira kuti kuchave nekuwanda uye kwakawedzera mapurojekiti eJMAP mune ramangwana. Semuenzaniso, pane mukana wekuti vanogadzira kubva kuOpen-Xchange, vari kugadzira IMAP server yeLinux masisitimu, vachinjire kune itsva protocol. Ramba IMAP ivo zvakanyanya , yakaumbwa yakatenderedza zvishandiso zvekambani.
Vagadziri kubva kuIETF neFastMail vanoti vashandisi vazhinji uye vazhinji vari kuona kukosha kweyero nyowani yakavhurika yekutumira mameseji. Vanyori veJMAP vanotarisira kuti mune ramangwana mamwe makambani achatanga kuita iyi protocol.
