How to fix HTTP 302 error?

Txoj Kev 1: Tshawb xyuas qhov teeb meem neeg rau zaub mov

Cov ntawv thov tuaj yeem khiav ntawm lub server uas siv ib qho ntawm ob qho kev sib koom tes feem ntau ntawm lub web server, Nginx lossis Apache. Ob lub web servers no suav ntau dua li 84 feem pua ​​ntawm qhov kev pabcuam thoob ntiaj teb web server!
Therefore, the first step in determining the 302 response code is checking the mandatory redirect instructions in the webserver program configuration file.

Rau Apache web Server

Kauj ruam 1: Qhib .htaccess cov ntaub ntawv ntawm tus neeg rau zaub mov

To identify the webserver, you need to find the key file. If you are using the Apache web server, locate the .htaccess file in your site’s root filesystem.

Piv txwv, yog tias koj cov program nyob hauv lub party sib koom, koj yuav muaj koj lub npe txuas nrog tus tswv tsev account, piv txwv. Hauv qhov no, feem ntau, cov npe ntawm daim ntawv thov hauv paus nyob hauv txoj kev:
/home/<username>/public_html/path, thus the .htaccess file is located at /home/<username>/public_html/.htaccess.

Kauj ruam 2: Nrhiav mod_rewrite kev coj ua

Thaum koj pom .htaccess cov ntaub ntawv, qhib nws rau hauv ntawv-kho thiab nrhiav cov kab uas siv RewriteXXX cov lus qhia ua rau Apache mod_rewrite module.

Txawm li cas los xij, lub tswv yim tseem ceeb yog tias RewriteCond kev taw qhia qhia cov qauv qauv ntawv uas tau muab piv rau qhov URL sau npe. Thaum ib tus qhua thov qhov URL sib xws rau ntawm ib qho chaw, RewriteRule kev qhia uas taug qab ib lossis ntau qhov RewriteCond cov lus qhia yuav ua tau pauv qhov kev thov mus rau URL sib xws.
Piv txwv li, cov hauv qab no yog kev sib koom ua ke yooj yim ntawm RewriteRule thiab RewriteCond uas txaus siab rau txhua qhov yuav tsum tau ntawm example.com, tab sis hloov ntxig nkag ua ib qho kev hloov mus ib ntus rau hauv tib lub URI nyob rau hauv ib ntus sau - example.com:

RewriteEngine ntawm RewriteCond% {HTTP_HOST} ^ piv txwv \ .com $ RewriteRule ^ (. *) $ Http://www.temporary-example.com/$1 [R = 302]

Daim ntawv ceeb toom ntxiv rau chij ntxiv rau hauv qab ntawm RewriteRule, uas qhia meej tias cov lus teb yuav tsum yog 302, uas qhia rau tus neeg saib xyuas browser tias nws yog ib qho kev hloov pauv ib ntus.

Kauj Ruam 3: Rov qab kho cov ntawv qhia hauv .htaccess

# BEGIN WordPress RewriteEngine Ntawm RewriteBase / RewriteRule ^ index \ .php $ - [L] RewriteCond% {REQUEST_FILENAME}! -F RewriteCond% {REQUEST_FILENAME}! -D RewriteRule. /index.php [L] # Xaus WordPress

Yog li, yog tias koj tau txais qhov tsis txawv ntawm RewriteRule lossis RewriteCond cov lus qhia hauv koj .htaccess cov ntaub ntawv uas tsis zoo li nws, sim muab nws cim ib ntus rau lawv (prefixed nrog #) thiab rov pib lub webserver los xyuas seb qhov teeb meem daws tau.

Rau Nginx web server

Kauj ruam 1: Qhib cov ntaub ntawv nginx.conf

Yog tias koj lub vev xaib ua haujlwm ntawm Nginx, koj yuav tsum nrhiav cov ntaub ntawv sib txawv ntawm kev teeb tsa. Cov ntaub ntawv no tau teev tseg uas yog nginx.conf los ntawm lub neej ntawd thiab pom nyob rau hauv ib qho ntawm cov ntawv sau npe ib txwm muaj nyob hauv qab no:

/ usr / local / nginx / conf, / etc / nginx lossis, / usr / local / etc / nginx.

Kauj Ruam 2: Rov sau dua cov lus qhia ntawm nginx.conf file

Tom qab kuaj pom, qhib cov ntaub ntawv nginx.conf hauv koj phau ntawv nyeem thiab nrhiav qhov sau rov qab cov lus qhia uas muaj feem ntsig txog qhov ntsuas kev taw qhia.

Piv txwv li, qhov no yog cov lus qhia thaiv lub tiaj (tau tshaj tawm cov lus tshaj tawm) uas teeb tsa lub virtual server los ntawm kev tsim cov kev xa mus ib ntus los ntawm abc.com mus rau ib ntus-abc.com:

neeg rau zaub mov {mloog 80; mloog 443 ssl; server_name www.abc.com; rov sau dua tshiab ^ / $ http://www.temporary-abc.com rov qab; }

Nginx rov sau cov lus taw qhia yog mus tib seem rau Apache RewriteRule thiab
RewriteCond vim tias lawv feem ntau suav nrog cov ntawv tshawb nrhiav cov qauv nyuab ntxiv.

Kauj Ruam 3: Tshawb xyuas txoj cai hloov pauv ntawm nginx.conf file

Nyob rau hauv txhua rooj plaub, tshawb xyuas cov nginx.conf cov ntaub ntawv rau qhov kev hloov pauv txoj cai uas muaj daim npav redirect (lwm tus chij rov tuaj teb chaws 301).

Thov nco tseg cov kev zam tshwj xeeb ua ntej koj rov pib dua lub neeg rau zaub mov kom kuaj xyuas seb puas yog daws teeb meem.

Txoj Kev 2: Tshawb cov software uas ua tsis tiav

Daim ntawv teev cov ntsiab lus tshwj xeeb ntawm RFC rau HTTP 1.0 tau hais tias lub hom phiaj ntawm "302 Nrhiav" cov lus teb cov lus teb yog los taw qhia tias tus neeg yuav tsum ua ib qho kev hloov pauv ib ntus.

However, many new browsers will process the code 302 received through the POST request as an invalid GET request.
This has triggered snags and confusion with particular web server programs that attempt to force the browser to perform the right work when it needs to be redirected temporarily.
Yuav kom daws tau qhov teeb meem no, RFC HTTP 1.1 cov ntaub ntawv tshwj xeeb xa rov qab 303 cov lus teb hloov, lwm 307 kev hloov pauv ib ntus, uas yog txoj hauv kev nkag siab los tswj POST-rau-GET lossis cov lus teb ib ntus.

Txoj Kev 3: Kev Ntxuav Cov Cav

Yuav luag txhua qhov web applications khaws cov ntaub ntawv ntawm tus server. Daim ntawv thov cav feem ntau sawv cev rau daim ntawv thov keeb kwm, zoo li cov nplooj ntawv twg, cov servers tau thov thiab txuas nrog, uas tau los ntawm cov ntaub ntawv muab, thiab lwm yam.

Lub cav nkag tau txuas nrog rau lub cuab yeej tam sim no uas khiav cov programmes thiab feem ntau muaj cov ntaub ntawv hais txog cov xwm txheej thiab kev noj qab haus huv ntawm txhua qhov kev pabcuam txuas nrog, thiab txawm tias cov ntaub ntawv hais txog lub server.
Google cov ntaub ntawv [PLATFORM_NAME] hauv CMS lossis siv [PROGRAMMING_LANGUAGE] txhawm rau sau npe thiab sau npe [OPERATING_SYSTEM] thaum pib thov kev cai rau cov ntaub ntawv ntxiv kom tau txais cov ntaub ntawv no.

Txoj Kev 4: Kho cov ntawv thov cov lej

Hauv rooj plaub, txhua txoj kev hais los saum toj saud tsis dhau, qhov teeb meem yuav yog nyob rau hauv tus neeg siv cov cai ntawm daim ntawv thov uas ua rau muaj teeb meem.

Sim los txiav txim siab qhov ua rau muaj teeb meem los ntawm kev txheeb xyuas cov ntaub ntawv thov thiab txheeb xyuas nws hauv cov neeg rau zaub mov thiab thov cov ntaub ntawv sau cia.
Nws yog lub tswv yim zoo los theej daim ntawv thov tag nrho rau koj lub khoos phis tawj kev tsim kho hauv ib cheeb tsam thiab nqis los ntawm nws kom pom tseeb tias ua li cas rau 302 kev soj ntsuam thiab pom cov cai rau txhua daim ntawv thov.

HTTP 302 Error: Conclusion

Thaum kawg, raws li koj tau pom, peb tsis tas yuav ntshai ntau yam txog HTTP 302 rau kev ua yuam kev. Tsis tas yuav mus txuas ntxiv, lawv yog txoj hauv kev zoo kom tsis txhob poob tsheb ntawm peb lub vev xaib nrog cov kev hloov tsis dhau uas tshwm sim rau lub xyoo.
