Los ntawm kev nyem rau ntawm peb tus lej ntawm sab xis ntawm lub qhov dej koj tuaj yeem nyem Access console, uas yuav ua rau koj nkag mus rau koj lub khoos phis tawj virtual.

Qhov tshiab browser qhov rai me me yuav qhib. Tam sim no, qhov no tsis yog lub desktop ib puag ncig, zoo li ntawm koj Windows 10 lossis Ubuntu nrog Graphical interface computer.

Txawm li cas los xij, txhua yam tuaj yeem ua tiav ntawm lub console interface.

Nws tsis txaus ntshai li nws zoo li:)

Kauj Ruam 6: Kho Kho Lub Tshuab Virtual (khoos phis tawj) PART 4

Koj tau ua tiav tsim koj tus kheej lub tshuab virtual hauv DigitalOcean huab.

Hauv cov kauj ruam tom ntej, koj yuav teeb tsa lub web server, hu ua Apache thiab teeb tsa koj tus kheej lub vev xaib.

Rub tawm Filezilla tus thov kev pabcuam ntawm no https://filezilla-project.org/download.php?platfo… (lossis nrhiav 32bit version rau 32bit operating system) thiab nruab nws. Nws yog FTP (Cov Ntaub Ntawv Hloov Cov Txheej Txheem) cov neeg siv khoom.

Koj yuav tuaj yeem nkag mus thiab hloov cov ntaub ntawv los ntawm thiab rau koj lub tshuab virtual.

Thaum tau teeb tsa, nyem cov ntaub ntawv → tus thawj tswj chaw site qhov chaw tshiab thiab sau cov ntaub ntawv zoo li ntawm daim duab saum toj no.

Raws tu qauv: SFTP (Cov Ntaub Ntawv Ruaj Ntseg Hloov Ntaub Ntawv)

Tus tswv tsev: IP ntawm koj lub server, nrhiav hauv koj qhov DigitalOcean project.

Tus neeg siv lub hauv paus thiab tus password yog qhov koj teeb tsa nws ntawm kev tsim koj cov dej.

Nyem OK thiab txuas rau koj lub tshuab virtual.

Koj yuav raug ceeb toom, tus tswv tseem ceeb tsis paub. Ua raws li daim duab thib ob.

Tsim lub nplaub tshev hauv zos rau txoj haujlwm, thiab rho tawm koj cov ntaub ntawv phiaj xwm koj yuav rub tawm ntawm no.

Koj yuav kho koj cov ntaub ntawv ntawm koj lub computer thiab xa lawv mus rau koj lub tshuab virtual txhua lub sijhawm koj xav sim lossis hloov kho cov cai.

Kauj Ruam 7: Nruab Web Server

Nkag mus rau koj lub droplet console nrog lub npe siv hauv paus thiab koj tus password.

Raws li peb tsis muaj lub graphical interface, peb siv cov lus txib los tswj koj lub tshuab virtual. Nov yog qee cov lus txib uas koj yuav siv ntawm Ubuntu (Linux):

• pwd - luam kuv phau ntawv teev npe tam sim no

• ls - teev cov ntaub ntawv thiab cov ntawv tais ceev tseg hauv kuv phau ntawv teev npe tam sim no

• cd / - txav mus rau / npe (ntawv tais ceev tseg, uas suav nrog linux cov npe loj xws li thiab lwm yam, rau hauv, khau raj, dev, hauv paus, tsev, var thiab ntxiv rau)

Los ntawm kev khiav, kuv txhais tau tias, nkag mus rau cov lus txib thiab nias nkag mus.

Tam sim no, peb yuav khiav apt -tau hloov tshiab -y txhawm rau hloov kho qhov system.

Khiav apt nruab apache2 -y rau nruab Apache web server.

Koj lub vijtsam zoo siab tos txais Apache yuav tsum nkag tau ntawm koj li https:// virtual-machine-ip los ntawm koj tus browser.

Hloov virtual-tshuab-ip nrog koj lub tshuab virtual ip, piv txwv li 165.12.45.123. Koj tseem tuaj yeem hla https:// raws li nws yuav raug txiav ntxiv.

Nrog koj zoo siab!

Nco tseg:

Yog tias koj xav kom koj lub vev xaib nkag tau los ntawm lub npe, tsis yog IP chaw nyob (zoo li kuv tau siv https://blinkmytree.live/), mus rau tus muab kev pabcuam site GoDaddy lossis zoo sib xws (namecheap.com thiab lwm yam..) thiab ua raws cov lus qhia ntawm no:

Qee lub npe sau yog pheej yig heev. Kuv qhov sau tau raug nqi tsuas yog 2 $ toj xyoo. Yeej tsim nyog tau nyiaj:)

Kauj Ruam 8: Txhim Kho Qhov Web Application Framework

Rov qab mus rau peb lub console. Tsis txhob ntshai:)

Siv Filezilla los tsim daim nplaub tshev npe app hauv /tsev, yog li /tsev /app yuav yog koj li ntawv

Khiav cd /home /app mus rau sab hauv app nplaub tshev.

Khiav apt nruab npm -y, rau installl npm tus thawj tswj pob. Qhov no yuav siv ob peb feeb.

Khiav npm init -y los tsim cov ntaub ntawv pob.json, uas yuav taug qab/nco qab pob loj cov ntaub ntawv hais txog ib qho app.

Khiav npm -txuag teeb tsa cors nthuav qhia rau nruab modules cors, nthuav tawm

Cors yog tus qauv rau teeb tsa kev nkag mus rau qhov chaw hla thiab nthuav tawm yog lub vev xaib daim ntawv thov.

Npm yog tus tswj hwm pob peb siv thiab peb yuav siv node.js JavaScript runtime los ua haujlwm rau peb cov ntawv thov kev sib txuas lus (API), uas yuav, ua ke nrog http server, lees txais HTTP thov rau thov xim rau LEDs, cim lawv qhov tseem ceeb (xim) hauv kev nco, thiab dhau qhov txiaj ntsig rau NodeMcu, thaum nws thov nws.

Nco tseg: Node hauv NodeMcu tsis muaj dab tsi ua nrog ntawm node.js. NodeMcu tuaj yeem hloov pauv nrog ib qho internet txuas nrog arduino pawg thawj coj txhim kho, NXP pawg thawj coj loj, lossis kev cai Microchip/NXP/Renesas/STM/Atmel PCB. Node.js kuj tseem tuaj yeem hloov nrog. Net moj khaum, PHP lossis lwm lub platform. Tab sis kom yooj yim, peb siv NodeMCU thiab Node.js.

Tam sim no, cia ua qhov kev sim, yog tias peb tuaj yeem ua haujlwm me me hauv node.js

Tsim cov ntaub ntawv npe index.js nrog notepad/notepad ++ lossis lwm tus kws kho mob lossis kev txhim kho ib puag ncig ib puag ncig koj siv (Visual Studio Code https://code.visualstudio.com/) hauv koj lub zos nplaub tshev.

Muab cov cai no tso rau hauv:

var http = xav tau ('http');

http.createServer (muaj nuj nqi (req, res) {

res.writeHead (200, {'Cov ntsiab lus-hom': 'ntawv nyeem/dawb'});

res.end ('Nyob Zoo Ntiaj Teb!');)) mloog (8080);

Txuag nws thiab hloov nws mus rau nplaub tshev/tsev/app raws li index.js nrog ob npaug nias/rub-nco ntawm cov ntawv hauv FileZilla.

Khiav ntawm qhov index.js, thiab cia nws khiav.

Tam sim no, peb tuaj yeem nkag mus rau peb nplooj ntawv ntawm https:// virtual-machine-ip: 8080 los ntawm peb tus browser. Ib nplooj ntawv dawb nrog Hello World text yuav tshwm sim.

Nrog koj zoo siab, koj nyuam qhuav tsim lub web server hauv node.js!

Kauj Ruam 9: Npaj Software

Mus rau console thiab nres qhov haujlwm los ntawm nias ctrl+C.

Hloov koj cov ntawv index.js hauv/home/app/thiab hloov nws nrog peb index.js hauv.

Koj tuaj yeem rub tawm txhua cov ntaub ntawv rau lub vev xaib ntawm no:

drive.google.com/file/d/1oIFdipoJxg6PF5klO…

Luam peb Chrismas tsob ntoo code los ntawm html nplaub tshev rau cov npe nyob deb/var/www/html/nrog Filezilla. Nws yuav siv sijhawm me ntsis. Yog nws nug koj, hloov index.html nrog tus tshiab.

Muab koj tus IP rov qab rau hauv koj lub vev xaib nyiam.

Koj nyuam qhuav ua koj lub vev xaib thov ua ntej-kawg muaj nyob ntawm https:// virtual-machine-ip.

Kauj ruam 10: Undestanding Back-end Code thiab Ua Nws Ua Haujlwm

Nco tseg: koj tus lej rov qab kawg yog nyob ntawm /home /app

Nco ntsoov, tom qab koj kho koj cov cai hauv ib cheeb tsam, tsis txhob hnov qab upload nws rau koj lub server siv FileZilla, thiab rov pib dua koj daim ntawv thov (console: ctrl+c, xub nce (qhia qhov kawg hais kom ua node index.js), nkag mus)

Txhawm rau ua haujlwm, koj yuav tsum nkag mus ob peb cov ntaub ntawv ua ntej.

Ua ntej, koj yuav tsum hloov pauv hostname sib txawv hauv index.js rau koj tus kheej lossis IP, (qee yam uas zoo li: 165.13.45.123).

Qhov thib ob, Kuv yuav coj koj hla txoj cai kom nkag siab nws. Nco ntsoov tsis txhob hla cov lus kuv tau ua hauv cov cai.

Koj tuaj yeem pom hauv cov ntawv index.js, uas peb tsim ib qho app siv cov qauv qhia. Tom qab ntawd, peb siv CORS cov cai rau nws, ntxiv APIs thiab pib http server. Tus neeg rau zaub mov no yuav tsis ua haujlwm web-nplooj dhau GET http thov, tab sis nws yuav ua haujlwm rau cov xeev coj los ntawm GET http thov thiab hloov kho cov xeev ntawm tau txais PUT http thov.

APIs yog ib txwm coj los pauv cov ntaub ntawv ntawm cov ntawv thov. Feem ntau peb siv yog REST APIs peb siv peb tus kheej. Lawv yog neeg tsis muaj tebchaws thiab tsis muaj kev txuas mus txuas ntxiv (shorturl.at/aoBC3, PUT thov yooj yim hloov kho cov xeev coj hauv app array sib txawv (nco), Tau txais kev thov yooj yim xa cov xeev coj mus rau tus neeg siv khoom.

Cov lus teb rau tus neeg siv khoom feem ntau yog hauv JSON qhov cim tseg, tab sis rau qhov lus teb yooj yim ntawm 30 LED xeev, peb tsuas xa txoj hlua ntawm 30 tus lej cais cais qhov tseem ceeb.

Kauj Ruam 11: Kev nkag siab txog Txoj Cai Lij Choj-kawg thiab Ua Nws Ua Haujlwm PART 1

Nco tseg: koj tus lej ua ntej-kawg yog nyob ntawm/var/www/html

Nco ntsoov, tom qab koj kho koj tus lej hauv zos, tsis txhob hnov qab xa nws mus rau koj lub server siv FileZilla. Tsis zoo li node.js, Apache rov pib dua nws tus kheej, tab sis koj yuav tsum rov qhib koj nplooj ntawv hauv koj tus browser. Siv ctrl+f5 txhawm rau kho tshiab thiab tshem tawm cov cache ntawm koj nplooj ntawv thiab.

Txhawm rau ua haujlwm, koj yuav tsum tau sau ob peb cov ntaub ntawv. Ua ntej, koj yuav tsum hloov qhov url sib txawv hauv xa_requestus muaj nuj nqi hauv index.html los ntawm blinkmytree.live rau koj tus kheej sau lossis IP, piv txwv: 165.13.45.123.

Qhov thib ob, Kuv yuav coj koj hla txoj cai kom nkag siab nws. Nco ntsoov tsis txhob hla cov lus kuv tau ua hauv cov cai. Nplooj ntawv yog cov ntawv HTML. Tawm ntawm txhua txoj cai CSS (nplooj ntawv style thiab cov ntsiab lus txoj haujlwm) ib sab, peb yuav saib xyuas cov haujlwm tseem ceeb. Xav paub ntau ntxiv txog CSS, txheeb xyuas

Peb xav tau cov yam ntxwv tseem ceeb no (cov kws tshaj lij ntawm txoj kev nrawm yuav hais cov neeg siv dab neeg) ntawm nplooj ntawv:

• Nyob yees duab kos rau hauv nplooj ntawv

• Ib qho nyem LEDs ntawm tsob ntoo christmas, uas tau siv hauv Gimp duab editor (https://www.gimp.org/).

• Kev sib txuas lus tiag tiag nrog tus neeg rau zaub mov, tos kom hloov pauv cov xeev.

Kauj Ruam 12: Nkag Siab Txog Txoj Cai Lij Choj-kawg thiab Ua Kom Nws Ua Haujlwm PART 2

Thaum peb muaj peb tsob ntoo Christmas nrog cov lej ntawm LEDs thiab xim xaiv, peb yuav tsum tsim thaj chaw thiab siv cov kev coj ua rau lawv, yog li ib zaug peb nyem rau ntawm cov xim LED nyob hauv ntu xaiv ntawm cov duab, xim yuav raug xaiv, thiab ib qho peb nyem rau ntawm LED, cov lus txib yuav xa mus rau tus neeg rau zaub mov, qhov twg Arduino yuav xaiv nws tus nqi.

Hauv HTML5, tus qauv HTML tshiab tshaj plaws, muaj qee yam hu ua daim duab qhia chaw. Nws tso cai rau peb los txheeb xyuas thaj tsam ntawm daim duab, uas peb tuaj yeem siv cov neeg mloog ua rau nws.

Raws li peb muaj ntau thaj tsam los txhais, peb siv cov cuab yeej online https://www.image-map.net/ txhawm rau txheeb xyuas cov cheeb tsam no thiab theej cov lej HTML rau peb nplooj ntawv.

Thaum peb ua qhov ntawd, peb tuaj yeem tso cov xwm txheej onclick nrog lub luag haujlwm nws hu thiab ntsuas ntawm tus lej LED rau txhua ntawm cov cheeb tsam no. Saib qhov screenshot saum toj no.

Kauj Ruam 13: Nkag Siab Txog Txoj Cai Pem Hauv Ntej thiab Ua Nws Ua Haujlwm PART 3

Sab hauv qhov kawg ntawm HTML lub cev, hauv ib cheeb tsam, peb tso qee qhov JavaScript, txhawm rau txheeb xyuas cov haujlwm peb hu hauv onclick cov xwm txheej. Thoob plaws ntiaj teb, peb txhais XMLHttpRequest, uas peb siv los xa PUT thov

Peb muaj ob txoj haujlwm:

muaj nuj nqi set_color (val)

muaj nuj nqi send_request (id)

Txog kev xeem API thov, Kuv pom zoo siv feem ntau siv software hu ua Postman https://www.postman.com/. Nws tso cai rau peb kom yooj yim xa API thov mus rau tus neeg rau zaub mov, yam tsis muaj kev txawj sau ntawv. Nws tso cai rau thuam tus neeg rau zaub mov, thiab lees txais kev thov ib yam nkaus.

Kauj Ruam 14: Kev nkag siab txog Txoj Cai Lij Choj-kawg thiab Ua Nws Ua Haujlwm PART 4

Koj daim ntawv thov ua haujlwm.

Ceev faj, cov lej tau thim rov qab, uas yog, 20 yog 1 thiab 1 yog 20, qhov no yog vim tias LEDs ntawm tsob ntoo pib hauv qab, tab sis rau kev paub siv tau zoo dua, peb tso qhov pib coj mus rau saum.

Koj tseem yuav xav tsim cov kwj tawm hauv YouTube yog tias koj xav tau, thiab hloov cov lej cim ntawm YouTube video nrog koj tus kheej.

Kauj ruam 15: Arduino Code

ESP8266 sau tus lej HTTP Client piv txwv piv txwv uas tau hloov kho me ntsis, tau txais cov ntaub ntawv los ntawm kuv lub vev xaib ntawm API hu.

Koj kuj tseem yuav tsum teeb tsa lub tsev qiv ntawv rau kev tswj hwm cov kab hluav taws xob LED yog tias koj xav siv tib qhov chaw nyob RGB sawb ib yam li kuv tau ua.

github.com/adafruit/Adafruit-WS2801-Librar…

Hauv daim duab kuv tau txuas nrog, koj yuav tsum tau ntxig koj lub npe wi-fi thiab tus password rau qhov url rau koj lub vev xaib (saib cov lus pom)

Peb pib hloov http cov lus teb rau hauv C-ntaus txoj hlua, yog li peb tuaj yeem siv C ua haujlwm strtok txhawm rau cais cov hlua los ntawm tus lej thiab sau cov lus leds nrog cov txiaj ntsig nyeem los ntawm server. Dua li peb hu ua lub luag haujlwm uas peb hla lub rooj, thiab raws li qhov muaj txiaj ntsig, peb tig cov xim raug rau tus neeg siv xav tau.

Qhov ntawd yog nws!

Nrog koj zoo siab, koj ua tau!

Kauj Ruam 16: RGB LED Chain

Ua, oh. Tam sim no nws yog lub sijhawm los so me ntsis ntawm txhua qhov coding:)

Txij li ESP8266 tsis muaj ntau GPIO tus pin los tswj LEDs ib tus zuj zus, Kuv tau siv qhov chaw nyob RGB LED saw:
