在基础版本的config目录下 web.php 或者高级版config目录下的main.php中配置
‘components‘ =>[ ‘request‘ => [ ‘parsers‘ => [ ‘application/json‘ => ‘yii\web\JsonParser‘, ], ], ],
在使用Yii::$app->request->post()时
调用yii\web\Request 中的post方法 :
public function post($name = null, $defaultValue = null) { if ($name === null) { return $this->getBodyParams(); } else { return $this->getBodyParam($name, $defaultValue); }+6
调用yii\web\Request 中的getBodyParams方法,解析内容是判断request组件中有没有相关content-type类型的解析器配置,有的话通过Yii ::createObject() 根据配置创建实例,调用相关解析器实例的parse方法解析数据内容,解析的数据内容是通过file_get_contents(‘php://input‘) 获取的:
/** * Returns the request parameters given in the request body. * * Request parameters are determined using the parsers configured in [[parsers]] property. * If no parsers are configured for the current [[contentType]] it uses the PHP function `mb_parse_str()` * to parse the [[rawBody|request body]]. * @return array the request parameters given in the request body. * @throws \yii\base\InvalidConfigException if a registered parser does not implement the [[RequestParserInterface]]. * @see getMethod() * @see getBodyParam() * @see setBodyParams() */ public function getBodyParams() { if ($this->_bodyParams === null) { if (isset($_POST[$this->methodParam])) { //post提交时,存在以$this->methodParam(默认是_method 名称)命名的参数时,直接把$_POST内容赋值给$this_bodyParams,同时删除$this->methodParam内容 $this->_bodyParams = $_POST; unset($this->_bodyParams[$this->methodParam]); return $this->_bodyParams; } //获取Content-Type $rawContentType = $this->getContentType(); if (($pos = strpos($rawContentType, ‘;‘)) !== false) { // e.g. application/json; charset=UTF-8 $contentType = substr($rawContentType, 0, $pos); } else { $contentType = $rawContentType; } if (isset($this->parsers[$contentType])) { //在request组件中存在相关$contentType类型配置时,创建该解析器,解析$this->getRawBody() 获取的内容 // $this->getRawBody() 是通过 file_get_contents(‘php://input‘)获取内容
$parser = Yii::createObject($this->parsers[$contentType]); if (!($parser instanceof RequestParserInterface)) { throw new InvalidConfigException("The ‘$contentType‘ request parser is invalid. It must implement the yii\\web\\RequestParserInterface."); } $this->_bodyParams = $parser->parse($this->getRawBody(), $rawContentType); } elseif (isset($this->parsers[‘*‘])) { $parser = Yii::createObject($this->parsers[‘*‘]); if (!($parser instanceof RequestParserInterface)) { throw new InvalidConfigException("The fallback request parser is invalid. It must implement the yii\\web\\RequestParserInterface."); } $this->_bodyParams = $parser->parse($this->getRawBody(), $rawContentType); } elseif ($this->getMethod() === ‘POST‘) { // PHP has already parsed the body so we have all params in $_POST $this->_bodyParams = $_POST; } else { $this->_bodyParams = []; mb_parse_str($this->getRawBody(), $this->_bodyParams); } } return $this->_bodyParams; }
yii\web\JsonParser json 解析器,是通过parse方法解析获取的json内容,主要是通过框架里面加强版的json_decode() 就是 yii\helpers\Json::decode($rawBody, $this->asArray) 把时间josn数据变为数组格式
/** * Parses a HTTP request body. * @param string $rawBody the raw HTTP request body. * @param string $contentType the content type specified for the request body. * @return array parameters parsed from the request body * @throws BadRequestHttpException if the body contains invalid json and [[throwException]] is `true`. */ public function parse($rawBody, $contentType) { try { $parameters = Json::decode($rawBody, $this->asArray); return $parameters === null ? [] : $parameters; } catch (InvalidParamException $e) { if ($this->throwException) { throw new BadRequestHttpException(‘Invalid JSON data in request body: ‘ . $e->getMessage()); } return []; } }
