我正在尝试通过 Appium 运行我的第一个测试并收到以下错误。

I want to use only Android default Browser and not Chrome. I dont know why Appium is trying to launch Chromedriver and Chrome Browser. Below is the code i used.

import java.net.URL;                

import org.openqa.selenium.WebDriver;                
import org.openqa.selenium.remote.CapabilityType;                
import org.openqa.selenium.remote.DesiredCapabilities;                
import org.openqa.selenium.remote.RemoteWebDriver;                
import org.testng.annotations.AfterMethod;                
import org.testng.annotations.BeforeMethod;                
import org.testng.annotations.Test;                

public class Appium {                

    public WebDriver driver;            

    @BeforeMethod            
    public void beforeMethod() throws Exception {            
        // set up appium        
        DesiredCapabilities capabilities = new DesiredCapabilities();        
        capabilities.setCapability(CapabilityType.BROWSER_NAME, "Browser");        
        capabilities.setCapability("platformName", "Android");        
        capabilities.setCapability("deviceName", "Android Emulator");        
        capabilities.setCapability("platformVersion", "4.4.2");        
        WebDriver driver = new RemoteWebDriver(new URL(        
                http://****:4723/wd/hub), capabilities);
        driver.get("http://www.yahoo.com");        
    }            

    @Test            
    public void f() {            

    }            

    @AfterMethod            
    public void afterMethod() {            
        driver.quit();        
    }            

}

最佳答案

您需要将以下 URL 设置为 http://0.0.0.0:9515/wd/hub 而不是 ****:4723...

WebDriver driver = new RemoteWebDriver(new URL(http://****:4723/wd/hub), capabilities);

Chromedriver 的端口默认为 9515，而不是 4723。 You should read the documentation on this. There are other capabilities that need to be set correctly (如 BROWSER_NAME)

关于java - Appium 错误 : A new session could not be created.(原始错误:未从 Chromedriver 获取 session 重定向)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/24626529/
