Error is absolutely correct, because your cssSelectoris incorrect, just omit last ]square bracket which is extra and try as below :-
错误是绝对正确的，因为您cssSelector不正确，只需省略最后一个]额外的方括号，然后尝试如下：-
driver.findElement(By.cssSelector("input[id='login-username']")).sendKeys("asdfasd");
You can use also #id css selecterto locate an element with their idattribute value using cssSelectoras below :-
您还可以使用以下#id css selecter方法定位具有id属性值的元素cssSelector：-
driver.findElement(By.cssSelector("input#login-username")).sendKeys("asdfasd");
To learn more about css selectorfollow this reference.
Seleniumalso locate an element using idattribute value of an element directly, so you can locate this element using By.id()as well as below :-
Selenium还id可以直接使用元素的属性值定位元素，因此您可以使用By.id()以下方法定位该元素：-
driver.findElement(By.id("login-username")).sendKeys("asdfasd");
