Question

我最近将我的硒从2.19.0更新到2.31.0。我在设置userAgent以进行测试时遇到问题。这是代码：

void testMessage() {
    verifySomething(this.driver, "iPhone");
}

void verifySomething(WebDriver driver, String userAgent) {
    String script = null;
    if (driver instanceof HtmlUnitDriver) {
        script = "navigator.userAgent=" + "'" + userAgent + "';";
    }
    else {
        // something
    }
    ((JavascriptExecutor) driver).executeScript(script);
}

我收到以下错误：

======= EXCEPTION START ========

EcmaError: lineNumber=[1] column=[0] lineSource=[] name=[TypeError] sourceName=[injected script] message=[TypeError: Cannot set property [Navigator].userAgent that has only a getter to iPhone. (injected script#1)]

==打电话给JAVASCRIPT ==

  function () {
      navigator.userAgent = "iPhone";
  }

======= EXCEPTION END ========

我知道它正在抱怨这个二传手。它用于在selenium 2.19.0中工作，但我猜他们可能已将该属性更改为只读。

非常感谢任何帮助。

Answer 1

您无法在navigator.userAgent中设置任何内容。

navigator.UserAgent只是关于您当前浏览器的信息。

Answer 2

对于FF使用此（profile.setPreference（“general.useragent.override”，“your useragent”）一切都需要从firefox个人资料中设置。

通过selenium设置userAgent是抛出异常
