解决这个问题的一种方法是在页面源代码中第1050行附近检查页面的<script>，这实际上是图表初始化的地方。在图表的初始化过程中有一个循环模式，其中画布元素被逐个查询以获得它们的上下文，然后是提供图表的标签和统计信息的变量。
此解决方案包括使用node.js，至少是包含以下模块的最新版本：

• cheerio，用于查询DOM中的元素
• axios，用于发送HTTP请求以获得页面源。
• abstract-syntax-tree以获得我们希望抓取的脚本的javascript对象树表示。

下面是solution和源代码：

const cheerio = require('cheerio');
const axios = require('axios');
const { parse, each, find } = require('abstract-syntax-tree');
async function main() {
    // get the page source
    const { data } = await axios.get(
        'https://stats.warbrokers.io/players/i/5d2ead35d142affb05757778'
    );
    // load the page source with cheerio to query the elements
    const $ = cheerio.load(data);
    // get the script tag that contains the string 'Chart.defaults'
    const contents = $('script')
        .toArray()
        .map(script => $(script).html())
        .find(contents => contents.includes('Chart.defaults'));
    // convert the script content to an AST
    const ast = parse(contents);
    // we'll put all declarations in this object
    const declarations = {};
    // current key
    let key = null;
    // iterate over all variable declarations inside a script
    each(ast, 'VariableDeclaration', node => {
        // iterate over possible declarations, e.g. comma separated
        node.declarations.forEach(item => {
            // let's get the key to contain the values of the statistics and their labels
            // we'll use the ID of the canvas itself in this case..
            if(item.id.name === 'ctx') { // is this a canvas context variable?
                // get the only string literal that is not '2d'
                const literal = find(item, 'Literal').find(v => v.value !== '2d');
                if(literal) { // do we have non- '2d' string literals?
                    // then assign it as the current key
                    key = literal.value;
                }
            }
            // ensure that the variable we're getting is an array expression
            if(key && item.init && item.init.type === 'ArrayExpression') {
                // get the array expression
                const array = item.init.elements.map(v => v.value);
                // did we get the values from the statistics?
                if(declarations[key]) {
                    // zip the objects to associate keys and values properly
                    const result = {};
                    for(let index = 0; index < array.length; index++) {
                        result[array[index]] = declarations[key][index];
                    }
                    declarations[key] = result;
                    // let's make the key null again to avoid getting
                    // unnecessary array expression
                    key = null;
                } else {
                    // store the values
                    declarations[key] = array;
                }
            }
        });
    });
    // logging it here, it's up to you how you deal with the data itself
    console.log(declarations);
}
main();
