【中文标题】无法启动 WebDriverAgent：无法将命令代理到远程服务器。原始错误：错误：连接 ECONNREFUSED 127.0.0.1:8100【英文标题】：Unable to start WebDriverAgent : Could not proxy command to remote server. Original error: Error: connect ECONNREFUSED 127.0.0.1:8100 【发布时间】：2017-09-21 23:45:45 【问题描述】：我有一个简单的 ios 自动化脚本。但是它会在指定的模拟器上启动 WebDriverAgent，之后会产生以下错误
[调试] [XCUITest] 无法启动 WebDriverAgent 会话：无法将命令代理到远程服务器。原始错误：错误：连接 ECONNREFUSED 127.0.0.1:8100
注意： 它总是使用 8100 的端口，即使我随机生成端口并在功能中设置 wdaLocalPort。
供您参考，请找到以下代码用于在模拟器上启动应用程序。
setup.java
int wdaDevicePort = 8000 + (int)(Math.random() * ((9000 - 8000) + 1));
File app = new File(inputMap.get(CommonConstant.APK_FILE_OR_WEBDRIVER_PATH));
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(MobileCapabilityType.BROWSER_NAME, "");
capabilities.setCapability(MobileCapabilityType.VERSION, inputMap.get(CommonConstant.BUILD_VERSION));
capabilities.setCapability(MobileCapabilityType.PLATFORM, inputMap.get(CommonConstant.PLATFORM_NAME));
capabilities.setCapability(MobileCapabilityType.DEVICE_NAME, inputMap.get(CommonConstant.DEVICE_NAME));
capabilities.setCapability(MobileCapabilityType.NO_RESET, true);
capabilities.setCapability(MobileCapabilityType.FULL_RESET, false);
capabilities.setCapability(MobileCapabilityType.AUTOMATION_NAME, "XCUITest");
capabilities.setCapability(MobileCapabilityType.UDID, inputMap.get(CommonConstant.PHYSICAL_DEVICE_ID));
capabilities.setCapability("wdaLocalPort", wdaDevicePort);
capabilities.setCapability("useNewWDA", true);
capabilities.setCapability("app", app.getAbsolutePath());
driverUrl = inputMap.get(CommonConstant.DRIVER_URL);
driverUrl = driverUrl.replace("Port", Integer.toString(appiumPort));
driver = new IOSDriver(new URL(driverUrl), capabilities);
在WebDriverAgentRunner xcode项目文件的FBConfiguration.m中随机生成端口。
+ (NSRange)bindingPortRange
int lower = 7200;
int upper = 8200;
int Port = lower + arc4random() % (upper - lower);
// 'WebDriverAgent --port 8080' can be passed via the arguments to the process
if (self.bindingPortRangeFromArguments.location != NSNotFound)
return self.bindingPortRangeFromArguments;
// Existence of USE_PORT in the environment implies the port range is managed by the launching process.
if (NSProcessInfo.processInfo.environment[@"USE_PORT"])
return NSMakeRange([NSProcessInfo.processInfo.environment[@"USE_PORT"] integerValue] , 1);
return NSMakeRange(Port, DefaultPortRange);

注意：-
我参考了 youtube 上的一个教程，但是他们运行自动化的 appium 日志具有以下行 iproxy 通过 USB 将本地端口连接到设备端口。 但在我的 appium 日志中不包含该活动。
不知道是不是这个问题？如果是问题，请提供解决步骤。提前致谢！！！
【问题讨论】：
【参考方案1】：确保开发者资料在苹果的开发者门户中有应用程序的详细信息 UDID 和捆绑 ID。如果 IPA 没有任何有效的配置文件，它将无法工作。 推荐你通过这个链接-http://appium.io/docs/en/drivers/ios-xcuitest-real-devices/
【讨论】：
【参考方案2】：而不是使用
[Appium] 应用程序：'/Users/thangaraj/Desktop/test.ipa'
在您的 xcode 中找到 .app 文件并替换路径。 那么它应该可以正常工作。
路径应该是这样的： 用户/thangaraj/Desktop/Xcode/DerivedData/mobile-ios-abc/Build/Products/Debug-iphonesimulator/abc.app

以上是关于无法启动 WebDriverAgent：无法将命令代理到远程服务器。原始错误：错误：连接 ECONNREFUSED 127.0.0.1:8100的主要内容，如果未能解决你的问题，请参考以下文章
