如何使用 Puppeteer 和 Chrome DevTools 协议修改请求 headers? (可能是 JS 语法问题)

How to modify request headers using Puppeteer & Chrome DevTools Protocol? (Possibly a JS syntax issue)

我有以下 Typescript 函数,假设 Chrome 浏览器已经使用 Puppeteer 启动。可以在 here.

中找到下面使用的 Fetch 函数的文档
async function modify(client: CDPSession) {
    client.on('Fetch.requestPaused', async ({ requestId, request, frameId, resourceType, responseErrorReason, responseStatusCode, responseHeaders, networkId }) => {
        // Correctly prints out the User-Agent header's value
        console.log(request.headers["User-Agent"]);

        // After this line is run, I can inspect the request.headers object and see that User-Agent was successfully edited
        request.headers['User-Agent'] = 'trying to edit this header';

        // Continuing the request gives an error
        await client.send('Fetch.continueRequest', {
            requestId: requestId,
            headers: request.headers,
        });
    });
}

这是我看到的具体错误:

Error: Protocol error (Fetch.continueRequest): Invalid parameters headers: array expected

如何解决这个错误并成功修改request.headers?这是我想不通的愚蠢 Javascript/Typescript 语法问题吗?

Fetch.requestPaused returns headers 作为 object。例如:

{
    "Upgrade-Insecure-Requests":"1",
    "Accept": "text/html,application/xhtml+xml"}
}

Fetch.continueRequest 期望 Array<{name: string, value: string}>。例如

[
    {"name": "Accept", value: "text/html,application/xhtml+xml"}
]

您可以使用 Puppeteer 正在使用的代码:

function headersArray(headers) {
  const result = [];
  for (const name in headers) {
    if (!Object.is(headers[name], undefined))
      result.push({name, value: headers[name] + ''});
  }
  return result;
}
