網頁轉pdf，這個工具真好用

兩天有個客戶需要把網頁轉為pdf，之前也沒開發過類似的工具，就在百度搜索了一波，主要有下面三種

在線轉pdf
使用瀏覽器打印功能轉pdf
使用本地軟件工具轉pdf

在線轉pdf

在百度（我一般用必應）搜索“在線網頁轉pdf”就有很多可以做這個事的網站，免費的如

PDF24Tools

各種pdf的操作都有，免費使用，速度一般。

doctron

開源免費項目，使用golang寫的，提供在線轉

doctron在線體驗demo

還有挺多其他的，可以自己搜索，但是都不符合我的預期。

使用瀏覽器打印功能轉pdf

在瀏覽器右鍵，點擊打印或者ctrl+p
在彈出的打印對話框中找到目標打印機選擇“另存為PDF”
點擊“保存”按鈕即可下載pdf了

使用本地軟件工具轉pdf

Doctron，這是我今天要介紹的重頭戲。

Doctron是基于Docker、無狀態、簡單、快速、高質量的文檔轉換服務。目前支持將html轉為pdf、圖片(使用chrome(Chromium)瀏覽器內核，保證轉換質量)。支持PDF添加水印。

使用chrome內核保證高質量將HTML轉為pdf/圖片。
簡易部署(提供docker鏡像,Dockerfile以及k8s yaml配置文件)。支持豐富的轉換參數。轉為pdf和圖片支持自定義大小。
無狀態服務支持。

管他的，先把代碼下載下來再說

git clone https://gitcode.net/mirrors/lampnick/doctron.git

倉庫

運行

go build
./doctron --config conf/default.yaml

運行截圖

轉pdf，訪問http://127.0.0.1:8080/convert/html2pdf?u=doctron&p=lampnick&url=<url>，更換鏈接中的url為你需要轉換的url即可。

轉換效果

然后就可以寫程序去批量轉換需要的網頁了，但是我需要轉換的網頁有兩個需求

1、網站需要會員登錄，不然只能看得到一部分

2、需要把網站的頭和尾去掉的

這就為難我了，不會go語言啊，硬著頭皮搞了，肯定有個地方打開這個url的，就去代碼慢慢找，慢慢調試，功夫不負有心人，終于找到調用的地方了。

第一步：添加網站用戶登錄cookie

添加cookie之前

添加cookie之后

第二步：去掉網站頭尾

chromedp.Evaluate(`$('.header').css("display" , "none");
		$('.btn-group').css("display" , "none");
		$('.container .container:first').css("display" , "none");
		$('.breadcrumb').css("display" , "none");
		$('.footer').css("display" , "none")`, &ins.buf),

打開網頁后執行js代碼把頭尾隱藏掉

第三步：程序化，批量自動生成pdf

public static void createPDF(String folder , String cl ,  String pdfFile, String urlhref) {
        try {
            String fileName = pdfFile.replace("/", ":");
            String filePath = folder + fileName;
            File srcFile = new File(filePath);
            File newFolder = new File("/Volumes/disk2/myproject" + File.separator + cl);
            File destFile = new File(newFolder, fileName);
            if(destFile.exists()){
                return;
            }
            if(srcFile.exists()){
                //移動到對應目錄
                if(!newFolder.exists()){
                    newFolder.mkdirs();
                }
                FileUtils.moveFile(srcFile , destFile);
                return;
            }
            if(!newFolder.exists()){
                newFolder.mkdirs();
            }
            String url = "http://127.0.0.1:8888/convert/html2pdf?u=doctron&p=lampnick&url="+urlhref;
            HttpEntity<String> entity = new HttpEntity<String>(null, null);
            RestTemplate restTemplate = new RestTemplate();
            ResponseEntity<byte[]> bytes = restTemplate.exchange(url, HttpMethod.GET, entity, byte[].class);
            if (bytes.getBody().length <= 100) {
                if(urlList.containsKey(urlhref)){
                    Integer failCount = urlList.get(urlhref);
                    if(failCount > 3){
                        System.out.println("下載失敗：" + cl + " / " + pdfFile +"  " + urlhref);
                        return;
                    }
                    failCount++;
                    urlList.put(urlhref , failCount);
                }else{
                    urlList.put(urlhref , 1);
                }

                createPDF(folder , cl ,  pdfFile , urlhref);
            }else{
                if (!destFile.exists()) {
                    try {
                        destFile.createNewFile();
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                }
                try (FileOutputStream out = new FileOutputStream(destFile);) {
                    out.write(bytes.getBody(), 0, bytes.getBody().length);
                    out.flush();
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

最終成果：

最新網盤)React18內核探秘：手寫React高質量源碼邁向高階開發

download：https://www.sisuoit.com/4316.html

國際化能夠使web站點或許app在不同的國家或許區域運用。能夠國際化的內容有文本，日期、時刻和數字的格式，還有錢銀等。目前市場上流行的react國際化框架主要有react-i18n和react-intl，本文主要以文本國際化來介紹兩種計劃的入門用法及比照。

React-i18next
介紹
react-i18next是基于i18next的一款強大的國際化框架，能夠用于react和react-native應用，以下是react-i18next一些特點：

基于i18next不只限于react，學一次就能夠用在其它地方
供給多種組件在hoc、hook和class的情況下進行國際化操作
適合服務端的烘托
歷史悠久，始于2011年比大多數的前端框架都要年長
由于歷史悠久所以更老練，目前還沒有i18next解決不了的國際化問題
有許多插件的支撐，比方能夠用插件檢測當時體系的言語環境，從服務器或許文件體系加載翻譯資源
預備開端
安裝依靠
# npm $ npm install react-i18next i18next --save # 如果需要檢測當時瀏覽器的言語或許從服務器獲取裝備資源能夠安裝下面依靠 $ npm install i18next-http-backend i18next-browser-languagedetector --save
在locales目錄下增加多言語裝備文件，文件類型為json。

E5277497-767F-43AF-9E38-599F5DAD2FD9.png
#en.json { "歡迎運用 react-i18next": "Welcome to react using react-i18next", "切換言語": "change language", "切換到中文": "change to Chinese", "切換到英文": "change to English", "切換到日文": "change to Japenese", "methods": { "renderProps": "change language with render props", "hook": "change language with hook", "hoc": "change language with hoc" }
#ja.json { "歡迎運用 react-i18next": "ご運用を歓迎する react-i18next", "切換言語": "言語を切り替える", "切換到中文": "中國語に切り替える", "切換到英文": "英文に切り替える", "切換到日文": "日本語に切り替える", "methods": { "renderProps": "renderProps方法で言語を変換する", "hook": "hook方法で言語を変換する", "hoc": "hoc方法で言語を変換する" } }
#zh.json { "methods": { "renderProps": "用renderProps轉化", "hook": "用hook轉化", "hoc": "用hoc轉化" } }
初始化裝備，新建i18n.js文件，對i18n進行初始化操作及插件裝備
import i18n from 'i18next'; import { initReactI18next } from 'react-i18next'; import Backend from 'i18next-http-backend'; import LanguageDetector from 'i18next-browser-languagedetector'; import resources from './locales/resources' // don't want to use this? // have a look at the Quick start guide // for passing in lng and translations on init i18n // load translation using http -> see /public/locales (i.e. https://github.com/i18next/react-i18next/tree/master/example/react/public/locales) // learn more: https://github.com/i18next/i18next-http-backend .use(Backend) // detect user language // learn more: https://github.com/i18next/i18next-browser-languageDetector .use(LanguageDetector) // pass the i18n instance to react-i18next. .use(initReactI18next) // init i18next // for all options read: https://www.i18next.com/overview/configuration-options .init({ fallbackLng: 'zh', lng: 'zh', debug: true, resources: resources, interpolation: { escapeValue: false, // not needed for react as it escapes by default } }); export default i18n;
將i18n.js文件引進到進口文件中App.js
import React from 'react'; import './i18n'; export default class App extends React.Component { render() { return ( <div> {/* 省略...... */} </div> ) } }
切換言語
<Button onClick={() => i18n.changeLanguage('zh')}>{t('切換到中文')}</Button>
經過RenderProps的方法國際化組件
import React from 'react'; import { Translation } from 'react-i18next'; const Index = () => { return ( <Translation> { t => { return ( <div style={{background: 'red', margin: 20, color: 'white', width: 200}}> {t('methods.renderProps')} </div> ); } } </Translation> ) } export default Index;
在hook中運用react-i18next國際化
import React from 'react'; import { useTranslation } from 'react-i18next'; const Index = () => { const { t } = useTranslation(); return ( <div style={{ background: 'yellow', margin: 20, width: 200 }}> {t('methods.hook')} </div> ) } export default Index;
運用高階組件（Hoc）的方法處理國際化
import React from 'react'; import { withTranslation } from 'react-i18next'; const Index = ({ t }) => { return ( <div style={{ background: 'blue', margin: 20, color: 'white', width: 200 }}> {t('methods.hoc')} </div> ); } export default withTranslation()(Index);
React-intl
介紹
React-intl經過context api的方法為react項目供給多言語支撐，能夠對文本、數字、日期等進行翻譯。以下代碼以組件的方法進行國際化操作。

預備開端
安裝依靠
npm i -S react-intl
在locales文件夾中創建多言語資源文件，與i18next不同的是，資源文件的類型為js類型，導出的是一個目標，由于翻譯的文本中能夠存在變量靈敏替換，比方代碼中的 { value }。

1603187400393.jpg
export default { welcome: "Welcome to use react-intl", changeToChinese: "change to Chinese", changeToEnglish: "change to English", changeToJapanese: "change to Japanese", description: "description", value: "use value {value}", function: "function as the child" }
export default { welcome: "react?intlの運用を歓迎します", changeToChinese: "中國語に切り替える", changeToEnglish: "英文に切り替える", changeToJapanese: "日本語に切り替える", description: "描繪", value: "値を使う（value) {value}", function: "関數はサブセットとする" }
初始化，將進口文件的組件App包裹在IntlProvider組件中。
import React from 'react'; import { IntlProvider, FormattedMessage } from 'react-intl'; import App from './App'; export default class Index extends React.Component { render() { const { locale } = this.state; return ( <IntlProvider locale={locale} messages={this.messages[locale]}> <App > </IntlProvider> ) } }
切換言語，react-intl沒有供給切換言語的接口，所以需要開發者手動完成。以下是經過按鈕點擊修改state中言語的類型來切換言語的。
import React from 'react'; import { IntlProvider, FormattedMessage } from 'react-intl'; import { Button, Row, Col } from 'antd'; import zh from './locales/zh'; import en from './locales/en'; import ja from './locales/ja'; export default class Index extends React.Component { messages = { zh: zh, en: en, ja: ja } state = { locale: 'zh' } render() { return ( <IntlProvider locale={this.state.locale} messages={this.messages[this.state.locale]}> <Row gutter={16} style={{ margin: 20 }}> <Col> <Button onClick={() => this.setState({ locale: 'zh' })}> <FormattedMessage id='changeToChinese' /> </Button> </Col> <Col> <Button onClick={() => this.setState({ locale: 'en' })}> <FormattedMessage id='changeToEnglish' /> </Button> </Col> <Col> <Button onClick={() => this.setState({ locale: 'ja' })}> <FormattedMessage id='changeToJapanese' /> </Button> </Col> </Row> </IntlProvider> ) } }
與react-i18next不同，react-intl只供給了組件（文本組件 FormattedMessage）和api（intl.formatMessage()）的方法來進行國際化處理，經過id獲取對應的言語文本進行國際化。
<div style={{ margin: 20, background: 'red', color: 'white', width: 233 }}> <FormattedMessage id='welcome' /> </div>
運用缺省音訊，如果當時的id在當時言語的資源文件中沒有對應的裝備，那就會顯示defaultMessage中的文本。
<div style={{ margin: 20, background: 'purple', color: 'white', width: 233 }}> <FormattedMessage id='defaultMessage' defaultMessage='運用缺省音訊' /> </div>
運用描繪
<div style={{ margin: 20, background: 'black', color: 'white', width: 233 }}> <FormattedMessage id='description' defaultMessage='描繪' description='運用描繪' /> </div>
經過value傳值
<div style={{ margin: 20, background: 'blue', color: 'white', width: 233 }}> <FormattedMessage id='value' values={{ value: 233 }} /> </div>
函數作為FormattedMessage的子組件，能夠經過這種方法來傳遞國際化的組件。
<div style={{ margin: 20, background: 'green', color: 'white', width: 233 }}> <FormattedMessage id='function'> { txt => ( <div style={{fontSize: 30}}>{txt}</div> ) } </FormattedMessage> </div>
比照
React-i18next初始化的時候需要將初始化裝備放置在初始化文件（i18n.js）中，然后將初始化文件(i18n.js)經過import的方法引進到進口文件中即可。當然也能夠經過I18nextProvider將i18n往下傳遞到各子組件。React-intl供給的是context api初始化計劃，需要將初始化裝備放在IntlProvider組件中，并且將進口文件的組件（如)作為IntlProvider的子組件來運用；
React-i18next供給了切換言語的接口(i18n.changeLanguage)，react-intl則需要對切換做一些封裝的工作；
React-i18next供給了三種方法進行國際化操作（render props、hook和hoc)， react-intl供給了api（intl.formatMessage()）和組件()兩種方法進行國際化；
React-i18next的言語資源文件為json格式，react-intl為js格式，一起支撐變量傳值；
React-i18next有很多插件能夠運用比方檢測當時體系言語，從后端獲取數據等；
React-intl除文本翻譯外還供給日期、時刻和金額的國際化支撐；
