Yuav Ua Li Cas Cov Neeg Tau Txais Cov Ntawv Xaib Xa rau Koj Hard Disk
Qhov hom tshaj plaws rau kev cia cov ntawv xa tawm yog hom ntawv mbox. MBOX sawv rau MailBOX. Mbox yog ib qho ntaub ntawv uas muaj xoom lossis ntau tshaj xa ntawv.
Hom ntawv mbox
Yog tias peb siv hom ntawv mbox khaws cov emails, peb muab tag nrho lawv ua ib daim ntawv. Qhov no tsim ntau dua los sis luv dua cov ntawv luam hauv phau ntawv (Internet email tsuas yog tshwm sim li 7-ntsis ASCII ntawv, txhua tsav txhua yam - cov ntawv ntxiv, piv txwv - yog encoded ) muaj ib tug email lus tom qab lwm. Yuav ua li cas peb paub tias qhov twg xaus thiab lwm pib?
Zoo hmoo, txhua tus email tau tsawg kawg ib qhov ntawm-ntawm nws pib heev. Txhua cov lus pib nrog "Txij Nkawm" (Los ntawm ua raws li los ntawm ib qho chaw cim dawb, kuj hu ua "From_" kab). Yog hais tias qhov sib lawv liag ("From") thaum pib ntawm ib txoj kab los ntawm ib txoj kab tas los yog nyob rau sab saum toj ntawm cov ntaub ntawv, peb tau pom cov lus pib.
Yog li cas peb saib rau thaum parsing ib mbox ntawv, yeej tseem zoo, kev npliag kab tom qab los ntawm "ntawm".
Raws li kev qhia, peb tuaj yeem sau qhov no ua "\ n \ nFrom. * \". Tsuas yog thawj thawj cov lus sib txawv. Nws pib pib nrog "Txij" pib ntawm kab ("^ From. * \").
& # 34; Ntawm & # 34; hauv lub cev
Yuav ua li cas yog tias raws nraim qhov sib lawv liag pom saum hauv lub cev ntawm tus email lus? Yuav ua li cas yog tias cov hauv qab no yog ib feem ntawm email?
... Kuv xa koj tuaj tshaj tawm tsab xov xwm tshaj tawm.
Los ntawm daim ntawv qhia no, koj tsis tas yuav ...
Ntawm no, peb muaj ib txoj kab tas mus li "From" thaum pib ntawm txoj kab. Yog tias qhov no tshwm nyob rau hauv cov ntaub ntawv mbox, peb unmistakably muaj pib ntawm ib cov lus tshiab. Qhov tsawg kawg yog qhov tus parser xav tias - thiab vim li cas ob tus neeg siv kev pabcuam email thiab peb yuav tsis totaub los ntawm kev xa email uas tsis muaj leej twg xa los yog txais neeg, tab sis pib nrog "Los ntawm daim ntawv qhia no".
Yuav tsum tsis txhob muaj qhov xwm txheej phem, peb yuav tsum ua kom "Tshaj tawm" tsis pom thaum pib ntawm kab tom qab ib kab tas li hauv lub cev ntawm lub email.
Thaum twg peb ntxiv ib cov lus tshiab rau mbox ua ntaub ntawv thov , peb saib kom zoo li qhov sib lawv liag hauv lub cev thiab tsuas yog hloov "From" nrog "> From". Qhov no ua rau misinterpretations tsis yooj yim sua. Qhov piv txwv saum toj no zoo nkaus li zoo li no thiab tsis pub ua ntxiv rau parser:
... Kuv xa koj tuaj tshaj tawm tsab xov xwm tshaj tawm.
> Ntawm daim ntawv no, koj tsis tas yuav ...
Qhov no yog vim li cas koj thiaj li nrhiav tau "> Txij Nkawm" hauv email uas koj xav tias yuav tsum yog "Txais".
