Kodi sintha amalandira kugwirizana kudzera 8080 (doko): malangizo, chithunzi ndi ndemanga

Port mu Intaneti kompyuta ndi chiwerengero zachilengedwe zomwe zinalembedwa chamutu OSI protocol. Bukuli lakonzedwa kuti kuzindikira wolandira wa ndondomeko ya paketi mu gulu lomwelo.

Monga ulamuliro, mu wosuta danga pa khamu ndi dongosolo anaika opaleshoni akubwera ndondomeko oposa mmodzi pa nthawi, ndipo aliyense wa iwo akuthamanga pulogalamu yeniyeni. Ngati ndondomeko bwanji maukonde kompyuta "chipolopolo" nthawi zifika mwa IP-paketi kuti cholinga chimodzi mwa mapulogalamuwo.

Kodi ntchito?

Ngati pulogalamu anagwiritsa ntchito kuwombola deta kudzera maukonde, ndondomeko izi zingatenge malo motere:

• Mu Os anapempha makamaka kudoko chiwerengero. Kachitidwe angapereke onse pulogalamu yake ndipo amaletsa kulanda (izi zimachitika pa nthawi imene doko nambala kale ntchito ndi ntchito ina).
• Pa Os tikukupemphani mwachindunji doko chiwerengero mu aliwonse. Dongosolo yokha amasankha ndi amapereka Program.

Kodi kutsegula doko (8080, 80 ndi zina zotero)? Mwa mfundo maukonde umasinthanitsidwa malinga ndi protocol yeniyeni (pakati pa njira ziwiri). Kuti kugwirizana wakhazikitsidwa, zotsatirazi chofunika:

• IP-adiresi ya sender ndi wolandira makamu (anafunika njira inamangidwa pakati pa iwo);
• protocol chiwerengero;
• Zipinda madoko onse (gwero ndi kopita).

Ngati kugwirizana ndi pa TCP, doko gwero ntchito monga opaleshoni dongosolo la wolandira kutsimikiza kufala kwa deta ndi pokonza wolandira kuti ayankhe.

Open ndi chatsekedwa madoko

Pa gawo la khamu ndi doko chiwerengero mchitidwewo sender monga mnzake ku adiresi kubwerera, amene anasonyeza pa emvulopuyo. nambala iyi akutchedwa iwowo.

Nthawi kumene ndondomeko pa khamu pa maziko zonse ntchito chimodzimodzi doko nambala kuti doko imatengedwa lotseguka. Mwachitsanzo, pulogalamu kugwirizana ndi makina akhoza kugwiritsa ntchito nthawi 80 kapena 8080 onse kulankhulana. Pamene ndondomeko sangathe kutsegula doko kuti imatengedwa chatsekedwa.

manambala doko

madoko onse ndi manambala awo m'kaundula m'njira zotchulidwa. Aliyense lakonzedwa kuti cholinga yake yeniyeni. Nthawi zambiri mukhoza kuona doko 8080. N'chifukwa chiyani muyenera magwiridwe ichi pogwiritsa ntchito Intaneti?

Malinga ndi kafukufuku boma doko ndi TCP ndipo lapangidwa ntchito ndi HTTP. Mwamseri, nawonso ntchito ndi Tomcat servlet chidebe olembedwa Java.

TCP-doko 8080 gwiritsani ntchito protocol yeniyeni kulankhulana, malingana ndi ntchito. Protocol ndi malamulo formalized lomwe limafotokoza mmene deta imafalikira pa maukonde. Thiabendazole angagwiritsidwe mu zinenero kuti ntchito pakati pa kompyuta kuwathandiza kulankhula bwino kwambiri.

The HTTP protocol, umene umadutsa 8080, ndiyo mtundu mgwirizano pakati asakatuli Internet ndi Intaneti. Chitsanzo china ndi IMAP protocol, omwe amasonyeza ubale maseva ndi IMAP makalata ndi makasitomala kapena, potsiriza, SSL protocol, amene n'chakuti mtundu ntchito mauthenga encrypted.

ukuthamana

Choncho, TCP-Port 8080 amagwiritsa ntchito Kufala Control Protocol. Iye ni mmodzi wa ndondomeko zazikulu Intaneti TCP / IP. Pamene amachita IP protocol yekha ndi mapaketi, TCP chimathandiza makamu awiri kukhazikitsa kugwirizana ndi kuwombola mitsinje deta. Iwo amatitsimikizira yobereka awo, komanso chakuti mapaketi adzaperekedwa kwa doko 8080 mu dongosolo limene iwo anatumizidwa. Kungakupatseni kugwirizana kwa 8080 - ichi kusiyana kwakukulu pakati TCP ndi UDP. UDP 8080 kuti sitingakumane kugwirizana chomwecho.

Kodi kutsegula doko 8080 pa Windows 7?

Kuchita izi, kupita "Yambani" wazakudya ndi kupeza Project Control. Ndi chofunika alemba pa "Network" boma wazakudya ndi kupeza "makhoma oteteza gawo." Mu "kuchotserapo" tsamba, kupeza "Wonjezerani Port". Inu adzatsegula bokosi kukambirana imene muyenera kulowa doko chiwerengero. Onetsetsani kuti zoikamo kutchulidwa TCP, ndiye kusankha bwino.

Kodi kutseka doko 8080? Chakwanira kukhazikitsa kugwirizana ndi doko lina yeniyeni.

MwaukadauloZida kasinthidwe HTTP ndi TCP tidzakulowereni

The protocol HTTP akuthamanga pamwamba pa TCP, koma likunena zambiri zina za kugawa uthenga. Pachifukwa ichi, proxies awiri kukhazikitsidwa mosiyana.

HTTP-magalimoto zikuphatikizapo chandamale khamu ndi doko uthenga. Iye akupitirira-TCP kugwirizana ndi TCP endpoint, ndiye pakati pa khamu makamaka ndi doko. Childs, HTTP-Post akufotokoza endpoint mofanana TCP-kugwirizana. Ngati inu kusintha kasinthidwe wa kasitomala ntchito HTTP tidzakulowereni Seva kugwirizana anapangidwa kwa khamu wina ndi doko, m'malo ulalo kutchulidwa HTTP-maadiresi. Izi zikutanthauza kuti mapeto mfundo TCP mu uthenga ndi yosiyana ndi mapeto imene chikugwirizana.

Mwachitsanzo, ngati HTTP-pempho anatumiza pempho http://192.0.2.1:8080/operation tsamba zikuphatikizapo «192.0.2.1:8080» mutu «khamu» HTTP Uthenga, amene anatumizidwa ku doko 8080 pa khamu 192,0. 2.1.

Komabe, ngati inu sintha pa HTTP-kasitomala kugwiritsa ntchito makina tidzakulowereni, zofunika TCP-kugwirizana zimapita kwa TCP endpoint iye, pamene uthenga lili ndi endpoint pachiyambi.

Mwachitsanzo, ngati inu sintha makasitomala kutumiza mauthenga awo pa makina tidzakulowereni pa 198281.100.1 doko 3128, ndi kasitomala akutumiza pempho http://192.0.2.1:8080/operation, uthenga lili «192.0.2.1: 8080" mutu «khamu», ndipo tsopano m'munda wa «Funsani-Line». Komabe, uthengawu tsopano anatumiza kudzera mwa TCP-kugwirizana pa 198.51.100.1:3128. Choncho, HTTP tidzakulowereni Seva akhoza kulandira mauthenga pa doko yemweyo (tidzakulowereni pa doko 8080) ndipo akhoza kuwatumiza ku misonkhano yosiyanasiyana pamaziko a nkhani wolandira.

Kodi sintha amalandira kugwirizana pa doko 8080?

Choncho, mutu wa «khamu» linakhulupirira HTTP / 1.1. Kugwirizana HTTP / 1.0 sakhala ndi izo, mwa yekha. Pachifukwa ichi, mankhwala amenewa, amene kudutsa tidzakulowereni si monga gulu ndi doko uthenga. Komabe, nkhani pa HTTP / 1.0, anatumiza kudzera Seva ndi tidzakulowereni, lili ndi chandamale khamu ndi doko mu "chingwe kafufuzidwe". Choncho, pakalibe mutu «khamu» sayambitsa mavuto tidzakulowereni lapansi.

Kuti athe TCP tidzakulowereni, muyenera kusintha kasinthidwe wa kasitomala ndi TCP endpoint mu pompopompo pa endpoint replaceable. Mosiyana HTTP, protocol si kupereka anamanga-imapanga ntchito tidzakulowereni. Ndiko kuti, ngati inu kulumikiza makina tidzakulowereni mwa TCP, chifukwa kufala kwa mudziwe kuti kokafikira sasamalira limagwirira iliyonse.

Kodi kukhazikitsa kugwirizana angapo kudzera 8080?

Njira yokhayo kwa TCP tidzakulowereni kulola kugwirizana kachitidwe angapo (ie, komaliza kopita), ziribe kanthu momwe magalimoto adzatumizidwa kwa mankhwala awa - ndi kumvera doko wina aliyense wa kachitidwe. Timatha inu kulumikiza ndi kukhalabe mudziwe zimene a manambala ake doko afanane ndi endpoint. Ndiye kasitomala ndi kukhazikitsidwa ndi doko tidzakulowereni lolingana lililonse dongosolo limene lifunika kulumikiza. TCP tidzakulowereni kumvetsera madoko ndi endpoints kake kukhazikitsidwa mu ntchito ya mu tidzakulowereni file kasinthidwe, RTCP_install_dir / httptcp / registration.xml. Choyamba, onani doko 8080 - ngati ndi lotseguka ndi kusakhulupirika, kusintha zina adzapatsidwa mu maminiti pang'ono.

Mu chitsanzo ichi 198.51.100.1 ndi IP-adiresi ya pa makina tidzakulowereni. magalimoto aliyense wotumizidwa kwa doko 3333 pa makina tidzakulowereni imatumizidwa doko 8080 pa adiresi zotsatirazi: www. Chitsanzo. kathakal:

Kotero inu muyenera kusintha file kasitomala kasinthidwe nthawi iliyonse inu kuwonjezera kopita latsopano magalimoto. Lamulo limeneli siligwira ntchito kwa HTTP-tidzakulowereni.

Mogwirizana pakati pa HTTP ndi TCP

Kumvetsa mmene doko amangomvera mu HTTP ndi TCP proxies, mwina muli ndi misonkhano iwiri pa 192.0.2.1:8080 ndi 192.0.2.1:8081, ndi tidzakulowereni Seva akuthamanga pa 198.51.100.1. Ngati iwo amasiyana ndi IP-adiresi m'malo mwa doko nambala chitsanzo ichi adzakhala yemweyo kupatula adiresi chogwirizana aliyense utumiki. Ngati iwo amayembekezera HTTP-magalimoto umodzi-HTTP zopempha tidzakulowereni kudoko endpoints onse TCP ungathe kutumizidwa kwa iye. Pamene HTTP amaona kuti uthenga ukunenedwa 192.0.2.1:8080, ndi tidzakulowereni patsogolo uthenga ku adilesi iyi, kapena kutsatira malamulo chilichonse chomwe cha msonkhano uno. Ndondomeko N'chimodzimodzinso 192.0.2.1:8081, ntchito doko chomwecho.

Ngati misonkhano iwiri m'malo kuyembekezera TCP magalimoto ayenera kukhala omasuka awiri TCP-tidzakulowereni doko chimafotokozera zinthu ziwiri mu kaundula kasinthidwe:

Kasinthidwe kasitomala kwa kusintha utumiki woyamba kuchokera «192.0.2.1:8080» pa «198.51.100.1:3333», ndi wachiwiri - ndi «192.0.2.1:8081» kuti «198.51.100.1:3334». Kasitomala anatumiza uthenga (TCP paketi), utumiki woyamba wa adiresi choyamba.

Seva tidzakulowereni kuwalandira ku doko (3333), koma sakudziwa chomwe deta ndi anatumizidwa pa nkhani imeneyi. Zonse zimene ankadziwa - kugwirizana ndi doko 3333. Choncho, Seva tidzakulowereni wofunsira kasinthidwe ake ndipo amaona kuti magalimoto pa doko izi ziyenera kunam'sintha kuti 192.0.2.1:8080 (kapena kuti m'pofunika kugwiritsa ntchito lamulo kwa utumiki uwu). Ngati simungathe kufika HTTP anu onse magalimoto, chifukwa kasinthidwe kasitomala siligwirizana ndi kasinthidwe wa Seva HTTP tidzakulowereni, muyenera kugwiritsa ntchito n'zosiyana HTTP-tidzakulowereni.

Mu m'malo mwa chandamale ulalo-maadiresi musankhe anu akufuna. Zimenezi ndi zofanana sintha pa TCP tidzakulowereni, imene musankhe monga endpoint mauthenga TCP dongosolo kasitomala ndi kulenga kutumiza ulamuliro.

kusiyana ndi kuti inu kuwonjezera mtundu lingaliro mwa ulamuliro umene n'chakuti HTTP, monga zotsatirazi: .

Kodi magalimoto kayendedwe?

Tsopano Seva tidzakulowereni ndi kukhazikitsidwa kulandira kokha HTTP-magalimoto doko yoikidwiratu, ndipo angagwiritsidwe ntchito wolemera kwambiri zosefera. Mwachitsanzo, makina akhoza zosefera kunja magalimoto pa chivundikiro, amene alibe njira yotsimikizika chake ulalo-adiresi, kapena amene sagwiritsa ntchito njira HTTP pokha, monga POST. Komabe, chifukwa pulagi sikuti ntchito, makina komabe ayenera kukhala mathero a katunduyo , kuti athe kutumiza magalimoto dongosolo. Mwachitsanzo, tinene kuti kasitomala ayenera kugwirizana kwa utumiki pa 192.0.2.1:8080 ndi ntchito n'zosiyana HTTP-tidzakulowereni pa 198.51.100.1:3333.

Pasanadutse kasitomala akhoza kugwiritsa ntchito makina tidzakulowereni, kasinthidwe kasitomala chifukwa cha msonkhano uno, muyenera kusintha ndi ulalo-maadiresi monga HTTP: // 192.0.2.1:8080/ opareshoni, pa HTTP: // 198.51.100.1:3333/ ntchito. Mawu anuwa amene anatumizidwa ku adiresi yatsopano ulalo, akulowa Seva tidzakulowereni.

Uthenga pempho lili TCP endpoint kuti tidzakulowereni (198.51.100.1:3333) mu chamutu "khamu," ndipo adiresi ya dongosolo, chifukwa kasitomala sakudziwa chomwe akutuma uthenga anajambulitsa. Izi wosalira kasitomala Mzimuyo chikhalidwe cha udindo umenewu pawiri. Choncho, tidzakulowereni amagwiritsa zinthu za , kudziwa kuti pempho akubwera doko 3333 amafuna imodzi mwa zotsatirazi: ayenera zimatumizidwa kwa dongosolo moyo 192.0.2.1:8080, ndi mutu «khamu» mu uthenga kukhala kusinthidwa. Kuti uthenga kuchitidwa malamulo onse a utumiki, mwachitsanzo, yolozera pulagi.
