Kif tiżviluppa App tal-iskaner tal-barcode billi tuża Java SDK. Implimenta kapaċitajiet ta’ skanjar QR fl-Applikazzjonijiet tal-Web, tal-Mowbajl u tad-Desktop tiegħek.
F’dan l-artikolu, se niddiskutu d-dettalji ta ‘kif tiżviluppa skaner tal-Barcode u app tal-iskaner tal-kodiċi QR billi tuża Java REST API. Aħna nifhmu li fl-ekonomiji b’ritmu mgħaġġel tal-lum, il-Barcodes huma soluzzjoni essenzjali u vijabbli għall-bejjiegħa u n-negozjanti għall-ħażna tad-dettalji tal-prodott. Matul is-snin, urew li huma għażla siewja u vijabbli għan-negozji. Tejbu ħafna l-effiċjenza u naqqsu l-overhead. Il-barcodes huma kemm kost-effettivi kif ukoll affidabbli. Fost benefiċċji oħra tal-użu tal-BarCode, speċifikati hawn taħt hemm ftit vantaġġi oħra tal-użu tagħhom
- Barcodes jeliminaw il-possibbiltà ta ‘żball uman
- L-użu ta ‘sistema tal-barcode inaqqas il-ħin tat-taħriġ tal-impjegati
- Barcodes huma estremament versatili u jistgħu jintużaw għal kull tip ta ‘ġbir ta’ data meħtieġa
- Jippermettu kontroll preċiż tal-inventarju, u għalhekk il-kontroll tal-inventarju jitjieb
- Barra minn hekk, il-Barcodes jipprovdu data aħjar jiġifieri barcode wieħed jista’ jipprovdi inventarju u dettalji tal-prezzijiet
Pertinenti għall-karatteristiċi kollha bħal dawn, Aspose.BarCode Cloud Java SDK jagħti s-setgħa lill-iżviluppaturi Java biex joħolqu kif ukoll jiskannjaw Barcode onlajn bl-użu tal-lingwa Java. Simili għall-API tal-Cloud l-oħra tagħna, Aspose.BarCode Cloud Java SDK jeħtieġ li tirreġistra kont fuq Cloud Dashboard. Jekk diġà rreġistrajt kont, tista’ tkompli tużah. Ladarba jkollok il-kont tiegħek lest, int tajjeb li tuża s-Servizzi tal-Cloud permezz tal-AppKey u l-AppSID.
Tista’ tikkunsidra li tuża Aspose Cloud storage jew, tuża kwalunkwe servizz ta’ cloud storage ta’ parti terza għall-ħażna u l-irkupru tal-fajls.
Simboliji tal-Barcode Appoġġjati
L-SDK jappoġġja bosta simboli tal-Barcode (aktar minn 60) bħal EAN, UPC, Codabar, PDF417, QR, MicroQR, Postnet, Planet, RM4SCC, eċċ. Ikollok ukoll l-għażla li tgħabbi l-informazzjoni eżistenti tal-BarCode u tissejvja l-output f’immaġni popolari formati, bħal JPEG, PNG, GIF, BMP, TIFF, EMF, WMF 9], SVG, EXIF, u ICON. Għal lista kompleta tas-simboliji appoġġjati, jekk jogħġbok żur Aspose.BarCode Cloud Java SDK.
Iġġenera Barcode
L-SDK joffrilek li toħloq immaġini tal-barcode Lineari, 2D u postali f’ħafna formati. Tista’ tispeċifika attributi tal-immaġni tal-barcode bħall-wisa’ tal-immaġni, l-għoli, l-istil tal-fruntiera, u l-format tal-immaġni tal-ħruġ. Tista’ wkoll tispeċifika t-tip tal-barcode u l-attributi tat-test bħall-post tat-test u l-istili tat-tipa skont ir-rekwiżiti tal-applikazzjoni tiegħek. Tipprovdi wkoll il-kapaċitajiet biex tissettja l-għoli tal-vireg u dawwar immaġini tal-barcode f’angolu.
L-eżempju li ġej juri l-passi biex jinħoloq Code39Standard Barcode, imqiegħed fuq l-allinjament Top-Center tal-paġna. Il-kulur tat-test huwa speċifikat bħala Navy, Orizzontali, u Vertikali riżoluzzjoni hija speċifikata bħala 200. Il-BarColor huwa speċifikat bħala Oranġjo, il-kulur fl-isfond huwa ssettjat bħala fidda u l-format tal-output huwa format JPEG.
Qabel ma nipproċedu aktar, nirrakkomandaw li żżur il-link li ġejja peress li token JWT huwa meħtieġ meta taċċessa l-API billi tuża l-kmand cURL.

Barcode Reader Online
Il-Cloud API huwa kapaċi wkoll li jirrikonoxxi informazzjoni minn barcodes eżistenti. Ikollok l-għażla li tispeċifika d-dettalji tat-tip tal-Barcode għal irkupru malajr jew tħalli l-API jiddetermina t-tip awtomatikament. Tista’ wkoll tispeċifika d-dettalji ta’ ChecksumValidation, DetectEncoding, jew tħalli l-API tiddeterminahom matul ir-runtime.

Konklużjoni
F’dan l-artikolu, tgħallimna l-passi dwar kif tiżviluppa App tal-iskaner tal-Barcode bl-użu tal-API REST Java. Bl-istess mod, l-API jippermettilek ukoll li timplimenta qarrej tal-kodiċi QR mill-fajl tal-immaġni. Minbarra li nużaw il-Java SDK, aħna jkollna wkoll għażla li tiskennja l-barcode onlajn billi tuża kmandi tal-cURL. M’hemmx bżonn ta’ tniżżil jew installazzjoni ta’ softwer addizzjonali. F’każ li tiltaqa’ ma’ xi kwistjonijiet waqt li tuża l-API, jekk jogħġbok tħossok liberu li tikkuntattjana permezz tal-forum ta’ appoġġ tal-prodott b’xejn.
