Question

我一直在尝试使用Selenium来推动Firefox。我使用了几乎相同的代码来驱动Chrome而没有问题。但是，当我尝试使用Firefox驱动程序时，浏览器会打开，停止，然后在大约60秒后，我会收到一条错误报告，内容如下：

Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms. Firefox   console output:

我已经检查了其他指南，他们建议我更新我的.jar文件。我正在使用selenium-java-3.0.0-beta2和Firefox 48.0.1进行测试，因此我的文件是最新的。我想让它正常运行。

更新：代码仍然无效，我已设置System属性以正确设置geckodriver。但是，我仍然无法让驱动程序正常运行。它甚至不再启动浏览器了。

import org.openqa.selenium.*;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.remote.DesiredCapabilities;

public class SimpleFireFoxDriver {


public static void main(String[] args) {

    System.setProperty("webdriver.gecko.driver","C:\\Selenium\\geckodriver.exe");

    DesiredCapabilities capabilities = DesiredCapabilities.firefox();
    capabilities.setCapability("marionette", true);

   WebDriver driver = new FirefoxDriver();

   driver.get("http://www.youtube.com");

   System.out.println("Made it to the promised land");

   driver.quit();

    }

}

编辑：FireFox本身的路径也位于此处： “C：\ Program Files \ Mozilla Firefox \ firefox.exe”

更改系统属性对我有用。将其更改为以下内容：

   test = "hello"
   # Open database connection
    db = MySQLdb.connect("127.0.0.1","admin","password","table" )

    # prepare a cursor object using cursor() method
    cursor = db.cursor()

    # Prepare SQL query to INSERT a record into the database.
    sql = ("""INSERT INTO %s (name,
            age, gender)
            VALUES (%s, %s, %s)""",(test))
    try:
        # Execute the SQL command
        cursor.execute(sql, (name, age, gender))
        db.commit()
    except:
        raise
        db.rollback()


    # disconnect from server
        db.close()

希望有所帮助。

这种情况正在发生，因为您设置了错误的系统属性。您需要按如下方式设置系统属性：

System.setProperty("webdriver.gecko.driver","C:\\Selenium\\geckodriver.exe");

Selenium firefox驱动程序希望在启动木偶驱动程序和启动firefox之前设置此System属性。如果您没有设置任何系统属性并尝试实例化Firefox驱动程序，那么您将收到以下错误：＆＃34;驱动程序可执行文件的路径必须由webdriver.gecko.driver系统属性设置。＆＃34;

希望这有帮助。

Answer 3

更改＆＃34; webdriver.gecko.driver ＆＃34;使用＆＃34; webdriver.firefox.marionette ＆＃34;救了我的命！例如：

<强>正确

System.setProperty("webdriver.firefox.marionette","C://selenium/gecko/geckodriver.exe");

不正确

System.setProperty("webdriver.gecko.driver","C://selenium/gecko/geckodriver.exe");

Answer 4

更改＆＃34; macro_rules! foo { ($($(#[$meta:meta])* foo $name:ident($ty:ty),)*) => { #[derive(Debug, Clone)] pub enum Foo { $($(#[$meta])* $name($ty),)* } impl Foo { pub fn display(&self) { match *self { $(Foo::$name(x) => println!("{}", x),)* } } } } } foo! { foo A(i32), foo B(i64), } fn main() { let a = Foo::A(32); let b = Foo::B(64); a.display(); b.display(); }＆＃34;用＆＃34; webdriver.gecko.driver＆＃34;救了我的生命也将Firefox从50降级到36

或尝试此代码：

webdriver.firefox.marionette

Answer 5

下载最新的Gecko驱动程序V0.17.0，这解决了我的错误，而没有更改setProperty或降级Firefox浏览器。

不太确定，这是否对您有帮助。
