如果我运行了TestNG测试类，它将显示错误------------ org.openqa.selenium.WebDriverException：处理命令时发生未知的服务器端错误。原始错误：无法将命令代理到远程服务器。原始错误：错误：套接字挂起（警告：服务器未提供任何堆栈跟踪信息）命令持续时间或超时：281毫秒构建信息：版本：'2.53.1'，修订版本：'a36b8b1cd5757287168e54b817830adce9b0158d'，时间：'2016-06-30 19:26:09' 系统信息：主机：'MON-PC305'，ip：'10 .101.0.119'，操作系统名称：'Windows 10'，os.arch：'amd64'，os.version：'10 .0'，java.version：'1.8 .0_144' 驱动程序信息：io.appium.java_client.android.AndroidDriver 功能[{appPackage = com.app.android.game.app，statBarHeight = 84，noReset = false，viewportRect = {top = 84，left = 0，width = 1440，height = 2308}，deviceName = emulator-5554，平台= LINUX，deviceUDID = emulator-5554，所需= {app =“ app path”，appPackage = com.app.android.game.app，appActivity = com.app.android.game.app.activities.login.riskWarningLogin.RiskWarningLoginActivity ，noReset = false，automationName = uiautomator2，skipUnlock = true，platformName = Android，deviceName = emulator-5554}，platformVersion = 9，webStorageEnabled = false，automationName = uiautomator2，takesScreenshot = true，skipUnlock = true，javascriptEnabled = true，platformName = Android，deviceApiLevel = 28，deviceManufacturer = Google，app = C：\ Users *** \ eclipse-workspace \ appname \ app.apk，deviceScreenSize = 1440x2560，networkConnectionEnabled = true，警告= {}，databaseEnabled = false，appActivity = com .app.android.game.app.activities.login.riskWarningLogin.RiskWarningLoginActivity，pixelRatio = 3.5，locationContextEnabled = false，deviceScreenDensity = 560，devi ceModel =为x86构建的Android SDK}] 会话ID：d275d496-08b0-4652-9aa9-67ae0476cdc8

Answer 1

不确定是否相同，但是当我通过uiautomator2运行appium自动化时，我在vivo手机上遇到了类似的问题。 appium错误日志就像

#include <iostream>
#include <vector>
#include <cmath>
#include <string>

//Printing factors help
void print(std::vector<int> const& factors)
{
    for (int i = 0; i < factors.size(); i++) {
        std::cout << factors.at(i) << ' ';
    }
}


int main() {

    //Restarting it
    std::string again;
    again = "Yes";

    //Actual loop
    while (again == "Yes") {

        //Variable/vectors
        std::string pfacts;
        double input = 0;
        double result = 0;
        double looper = 2;
        int looper2 = 2;
        int printed = 0;
        int printed2 = 0;

        std::vector<int> factors;
        std::vector<int> holders;

        //Asking for number
        std::cout << "Please enter your number.\n";
        std::cin >> input;
        double holder = input;

        //Ratting out trolls
        if (input == 0) {
            std::cout << "Your number is neither.\n";
            looper = 1000003;
        }

        if (input == 1) {
            std::cout << "Your number is neither.\n";
            looper = 1000003;
        }


        //Prime/composite loop
        while (looper < 1000002 and input != 1 and fmod(result, 1) == 0) {
            result = input / looper;

            //Finding composite
            if (fmod(result, 1) == 0 and printed == 0) {
                std::cout << "Your number is composite.\n";
                printed = 1;
                looper = 1000003;
            }

            //Finding prime
            else if (fmod(result, 1) != 0 and printed2 == 0) {
                std::cout << "Your number is prime.\n";
                printed2 = 1;
            }

        }

        //Asking about factors
        if (printed == 1) {
            std::cout << "Would you like to know it's prime factors? (Please type Yes or No exactly)\n";
            std::cin >> pfacts;
        }

        //Actually finding them
        if (pfacts == "Yes") {
            while (looper2 < 1000002) {

                if (holder / looper2 == 0) {
                    factors.push_back(holder);
                    looper2 = 1000003;
                }

                if (looper2 < 1000002 and fmod  (fmod(holder, looper2),   1) == 0 and looper2 % 2 != 0 or looper2 / 2 == 1) {
                    factors.push_back(looper2);
                    holder = holder / looper2;
                }
                looper2 = looper2 + 1;
            }

            //Printing them
            print(factors);
            std::cout << "\n";


        }













        //Again?
        std::cout << "Do you need to input another number? (Please type, exactly: Yes or No)\n";
        std::cin >> again;

    }

}

我这个问题的原因是io.appium.uiautomator2.server被系统进程com.vivo.abe杀死，导致我从logcat捕获了以下日志

[debug] [W3C (9ae907c5)] Encountered internal error running command: UnknownError: An unknown server-side error occurred while processing the command. Original error: Could not proxy command to remote server. Original error: Error: socket hang up
[debug] [W3C (9ae907c5)]     at JWProxy.command (/usr/local/lib/node_modules/appium/node_modules/appium-base-driver/lib/jsonwp-proxy/proxy.js:261:13)
[HTTP] <-- POST /wd/hub/session/9ae907c5-5319-4f0b-92dc-fdaa47cfdcc5/element 500 139 ms - 530

com.vivo.abe（名称为Vivo Wisdom引擎）是vivo手机上的系统应用，无法卸载或强制停止。有一种解决方案可以解决此问题，只需将io.appium.uiautomator2.server添加到白名单中，则com.vivo.abe将不再对应用程序执行kill。

方法设置->电池->高背景功耗，然后将io.appium.uiautomator2.server添加到允许列表中。

执行该操作后，io.appium.uiautomator2.server将不再被杀死，并且自动化脚本可以顺利运行。

希望这可以为解决该问题提供参考。

Answer 2

发生这种情况是因为您在代码中打开了 2 个驱动程序实例。

URL url = new URL(Common.getProperty("URL"));
driver = new AndroidDriver<WebElement>(url, capabilities);

以上内容。确保你只在你的套装中初始化过一次，否则它会遇到你遇到的同样错误。

处理命令时发生未知的服务器端错误。无法将命令代理到远程服务器。原始错误：错误：套接字挂起
