Question

我正在使用Goutte来解析某些网站。

这是我的代码示例

$goutteClient = new Client();
$response = $goutteClient->setHeader('User-Agent', $userAgent)
->setClient($guzzleClient)
->request('GET', 'https://example.com');

$response是Symfony\Component\DomCrawler\Crawler

的实例

那么，如何获取响应状态代码以检查它是404错误还是其他错误？

Answer 1

对我有帮助

if ($goutteClient->getResponse()->getStatusCode() === 404){}

Answer 2

$goutteClient->getResponse()将为您提供最后一个请求的响应对象。

完整代码是：

$res = $goutteClient->getResponse();
if ($res->getStatusCode() === 404) {}

 handleSubmitChat = (event) => {
            //algorithm chatbot algorithm
            event.preventDefault();

            //for single string match example: user can input water an get water word related answers...
            // let matches = this.state.keywords.filter(s => s.includes(this.state.humanarea))
            // Split spaces after user sends
            let searchString = this.state.humanarea.toLowerCase()
            let searchStringSplit = searchString.split(/(\s+)/).filter(function (e) { return e.trim().length >= 3; })
            if (searchStringSplit.length >= 1) {
                this.state.matches = this.state.keywords.filter(replykey => {
                    let containsAtLeastOneWord = false;
                    // If at least a word is matched it returns the matching answers!
                    searchStringSplit.forEach(word => {
                        if (replykey.toLowerCase().includes(word)) {
                            containsAtLeastOneWord = true;
                        }
                    })
                    if (containsAtLeastOneWord) {
                        return replykey

                    }console.log(replykey)

                })
                this.setState({
                    botarea: this.state.matches
                })
                console.log(this.state.matches)

            }
        }

                        greet: `//user input should first match these key words as synonyms...`
                            [
                                'greetings',

                        group4: ['bees',],
                        group5: ['honey',]
                    }

                ]
