Kui olete harjunud t\u00f6\u00f6tama mudelitega (mis tahes vundamendis v\u00f5i raamistikus, kuid konkreetselt WordPressiga), on t\u00f5en\u00e4oline, et peate mingil hetkel mudeli eksemplari seeriasse viima.<\/p>\n

Muidugi on PHP sisseehitatud funktsioonide abil klassi kirjutamine andmebaasi piisavalt lihtne; Siiski on oluline lisada veidi paindlikkust, eriti mis puudutab selle k\u00e4ttesaadavaks tegemist muudel platvormidel.<\/p>\n

Oletame n\u00e4iteks, et loote WordPressis rakendust, mille mudelis on esindatud teatud t\u00fc\u00fcpi unikaalne teave. Seej\u00e4rel on mudelile juurdep\u00e4\u00e4s mobiilirakenduse kaudu REST API<\/a> kaudu .<\/p>\n

V\u00e4idetavalt on \u00fcks lihtsamaid viise selle tegemiseks kasutada JSON-i. See on vorming, mis t\u00f6\u00f6tab erinevates keeltes ja platvormidel, mida nimetatud platvormid saavad h\u00f5lpsasti serialiseerida ja deserialiseerida ning vajadusel saata.<\/p>\n

Ja seda on PHP-s uskumatult lihtne rakendada. Peate lihtsalt veenduma, et teie klass rakendab JsonSerializable<\/a> liidest.<\/p>\n

\"WordPressi<\/a><\/p>\n

Dokumentatsiooni p\u00f5hjal teeb liides j\u00e4rgmist.<\/p>\n

\n

JsonSerializable’i rakendavad objektid saavad kohandada oma JSON-i esitust, kui need on kodeeritud koodiga json_encode().<\/p>\n<\/blockquote>\n

Ainus meetod, mida klass peab pakkuma, on jsonSerialize<\/strong> ja kuigi on t\u00f5en\u00e4oline, et soovite j\u00e4rjestada k\u00f5ik objekti atribuudid (ja ka selle oleku alati, kui seda kutsutakse), saate rakendust vastavalt oma soovile kohandada.<\/p>\n

N\u00e4iteks kui teil on klass ja soovite lihtsalt selle nime atribuuti rakendada, siis rakendaksite funktsiooni j\u00e4rgmiselt<\/a> :<\/p>\n

<?php\n\nclass Acme implements JsonSerializable \n{\n  \/**\n   * @var string the name of the model as represented on the front-end.\n   *\/\n  protected $name;\n\n  \/\/ More code here.\n\n  \/**\n   * @return string a JSON representation of this class\n   *\/\n  public function jsonSerialize()\n  {\n      return [\n        'name' => $this->getName()\n      ];\n  }\n}<\/code><\/pre>\n
Kui soovite sellele veidi keerukamat lisada, saate teha<\/a> j\u00e4rgmist:<\/p>\n
<?php\n\nclass Acme implements JsonSerializable \n{\n  \/**\n   * @var string the name of the model as represented on the front-end.\n   *\/\n  protected $name;\n\n  \/**\n   * @var array an array of features about this object.\n   *\/\n  protected $features;\n\n  \/\/ More code here.\n\n  \/**\n   * @return string a JSON representation of this class\n   *\/\n  public function jsonSerialize()\n  {\n      return [\n        'name' => $this->getName(),\n        'features' => [\n          'hair' => $this->getHairColor(),\n          'eyes' => $this->getEyeColor(),\n         ],\n      ];\n  }\n}<\/code><\/pre>\n
Ja kui soovite atribuutide serialiseerimisega tegeleda, saate massiivi<\/a> koostamiseks kasutada ts\u00fcklit :<\/p>\n
<?php\n\nclass Acme implements JsonSerializable \n{\n  \/**\n   * @var string the name of the model as represented on the front-end.\n   *\/\n  protected $name;\n\n  \/**\n   * @var array an array of features about this object.\n   *\/\n  protected $features;\n\n  \/\/ More code here.\n\n  \/**\n   * @return string a JSON representation of this class\n   *\/\n  public function jsonSerialize()\n  {\n      $objectArray = [];\n      foreach ($this as $key => $value) {\n          $objectArray[$key] = $value;\n      }\n\n      return $objectArray;\n  }\n}<\/code><\/pre>\n
Igal juhul, kui klassi eksemplar edastatakse funktsioonile json_encode, kutsub see objektil esile funktsiooni<\/strong> jsonSerialize<\/strong>, et saaksite objekti esituse JSON-vormingus, nagu olete kavandanud.<\/p>\n
See on uskumatult lihtne ja kasulik, kui tegemist on andmete kasutamisega mitmel platvormil (v\u00f5i isegi samal platvormil<\/a> ).<\/p>\n
