Amachweba ayingxenye ebalulekile yesistimu yokuxhumana yekhompyutha. Banikeza isango lapho izinhlobo ezahlukene zethrafikhi yedatha zishintshisana phakathi kwekhompyutha nenethiwekhi. Kwesinye isikhathi, ngenxa yokuphepha noma ezinye izizathu, ungadinga ukuvala izimbobo ku-Windows. Lesi sihloko sihlose ukuchaza ukuthi lokhu kungenziwa kanjani ngesinyathelo ngesinyathelo, kusetshenziswa izibonelo zekhodi ezifanele ezibhalwe ku-TypeScript.
Ukuqonda Amachweba Nokubaluleka Kwawo Kumanethiwekhi
Amachweba angacatshangwa njengamadokhi abonakalayo lapho ukuxhumana phakathi kwekhompyutha yakho nomhlaba wangaphandle kwenzeka. Ngayinye yalezi zimbobo ihlotshaniswa nenqubo ethile noma isevisi futhi ibonakala ngenombolo ehlukile, eyaziwa ngokuthi inombolo yembobo.
Ukuze ukuxhumana kwenzeke , kokubili amakhompyutha okuthumela nokwamukela kumele abe nembobo efanayo evulekile. Uma imbobo yenethiwekhi ivuliwe, kusho ukuthi isilungele ukwamukela idatha. Ngokuphambene nalokho, uma imbobo ivaliwe, ayilungele ukwamukela idatha.
Izizathu zokuthi kungani ungase ufune ukuvala amachweba
Kunezizathu ezahlukahlukene zokuthi kungani kungadingeka uvale imbobo. Esinye sezizathu ezivame kakhulu ukwandisa ukuphepha kwesistimu iyonke. Ngokuvala amambobo angadingekile noma angasetshenziswanga, ungavimbela ukufinyelela okungagunyaziwe kwikhompyutha yakho.
Esinye isizathu kungaba ukuxazulula izingxabano zesofthiwe. Ezinye izinhlelo zokusebenza zingazama ukusebenzisa imbobo efanayo ngesikhathi esisodwa, kubangele ukungqubuzana. Ngokuvala imbobo exhunywe kuhlelo lokusebenza oluthile, ungakwazi ukuxazulula lezi zingxabano.
const net = require('net');
const testPort = (port: number): Promise<{port: number, available: boolean}> => {
return new Promise((resolve) => {
const server = net.createServer();
server.unref();
server.on('error', () => resolve({port, available: false}));
server.listen(port, () => {
server.close(() => resolve({port, available: true}));
});
});
};
Ekhodini ye-TypeScript engenhla, sisebenzisa imojuli 'net' ye-Node ukuze sakhe iseva elalela imbobo ethile. Uma kunephutha (okusho ukuthi imbobo cishe isetshenziswa olunye uhlelo lokusebenza), ibuyisela itholakala ingamanga. Uma ingalalela ngaphandle kwezinkinga, kusho ukuthi ichweba alisetshenziswa, yingakho libuya litholakala liyiqiniso.
Ukuvala Izimbobo ku-Windows
IWindows inomshini owakhelwe ngaphakathi wokuvala izimbobo: ngeWindows Firewall. Ngokusetha imithetho ethile, ungavimba izimbobo ngaleyo ndlela uzenze 'zivalwe.' Ukuze wenze lokhu, zulazulela ku-'Windows Defender Firewall enokuphepha okuthuthukile' futhi ngaphansi 'kwemithetho engaphakathi', ungasetha umthetho omusha wokuvimba imbobo.
Qaphela lapho uvala izimbobo, noma kunjalo. Amanye amasevisi nezinhlelo zokusebenza zidinga izimbobo ezithile zivuliwe ukuze zisebenze kahle. Ngakho-ke, qiniseka njalo ukuthi ichweba elizovalwa alibalulekile ekusebenzeni okujwayelekile kohlelo.
Imboni yezemfashini ayimile futhi ithonywa izitayela nokunyakaza okuhlukahlukene. Izitayela ezahlukene, ukubukeka, kanye nenhlanganisela yezingubo kuvame ukuhluka, okubonisa izikhathi zomlando ezihlukahlukene, izici zamasiko, nezinkulumo ngazinye. Ngaphezu kwalokho, izinhlelo zemibala zidlala indima ebonakalayo ekuphakamiseni isimo noma ithoni ethile. Umlando wesitayela ngasinye semfashini uyakhanga futhi uyakhanyisa, ngokuvamile uveza imininingwane ethakazelisayo ngomphakathi ngesikhathi esithile. Imfashini, ngempela, ijule kakhulu kunengubo enhle—iwumfanekiso nomyalezo emhlabeni.
