我想在一个括号中连接3个变量,如PHP.

即

在PHP中:

getimagesize($path.$image)

我们可以用点表示法连接变量.我怎样才能在树枝上重现这个？

{{ path.key }} 没有按预期工作.

谢谢

我有一个关于selenium的代码来测试表单.但首先我转到另一个页面,然后重定向到我的页面.当我将cookie设置为新域时,我收到错误:

Exception in thread "main" org.openqa.selenium.InvalidCookieDomainException: You may only set cookies for the current domain

我的代码:

//it is going to example.com and example redirect me to the "example.com" all cookie domains is "example.com"
driver.get("http://www.example.com?id=1");

 Set<Cookie> cookies = driver.manage().getCookies();
 Iterator<Cookie> itr = cookies.iterator();

    while (itr.hasNext()){
    Cookie c = itr.next();
    System.out.println("Cookie Name: " + c.getName() + " --- " + "Cookie Domain: " + c.getDomain() + " --- " + "Cookie Value: " + c.getValue());

    driver.manage().addCookie(c);
    }

我该如何管理？我必须为example.com获取/设置cookie

我在页面上有一个javascript,如下所示:

new Shopify.OptionSelectors("product-select", { product: {"id":185310341,"title":"10. Design | Siyah \u0026 beyaz kalpli",

我想得到"185310341".我在谷歌搜索了几个小时但找不到任何东西,我希望你能帮助我.我怎么能刮掉那个javascript并得到那个id？

我试过那段代码:

id = sel.search('"id":(.*?),',text).group(1)
print id

但我得到了:

exceptions.AttributeError: 'Selector' object has no attribute 'search'

我有3类:Course,CourseEntry和Transcript.在成绩单中,我有一个添加课程的功能,如:

public class Transcript {
    CourseEntry coursestaken[] = new CourseEntry[6];

    public void addCourse(Course course)
    {
        coursestaken[lastIndexOf(getCoursestaken())] = new CourseEntry(course);
    }
    (lastIndexOf gives me the empty array index - it's working on)

在我的CourseEntry:

public class CourseEntry {
    Course course;
    char grade = 'I';

    public CourseEntry(Course course)
    {
        this.course = course;
    }

在我的Course:

public  class Course {
    int courseNumber,credits;
    String courseName;

    public Course addNewCourse(int courseNumber, int credits, String courseName)
    {
        this.courseNumber = …
