请求主体不包含所需的参数“手柄”(Request body does not contain req

请你帮我，我有问题，进行测试时，在虚拟机（C＃/ Safari的12 / MacOS的10.13）。

Selenium.Support: version=3.141.0
Selenium.WebDriver version=3.141.0
SpecFlow version="2.1.0

我有陷阱：

同样的话题早已存在

您的问题，采用了全新的webdriver协议是由于Safari浏览器12。这是造成一些incompatabilty问题。问题在这里已经报道： https://github.com/SeleniumHQ/selenium/issues/6026

你可以通过safaridriver一个--legacy标志，该标志被张贴mjdease上的旧协议https://github.com/SeleniumHQ/selenium/issues/6026

const webdriver = require('selenium-webdriver');
const safari = require('selenium-webdriver/safari');

new webdriver.Builder()
    .usingServer(await new safari.ServiceBuilder().addArguments('--legacy').build().start())
    .forBrowser('safari')
    .build();
