真机远程调试 ( IOS Android 以及微信,weex, react native)和vscode配置各种开发调试环境

1.以前cordova远程调试,Android的直接连接USB后,用chrome打开chrome://inspect网址

   (有人遇到第一次打开chrome inspect是空白页面,是因为第一次要下载一些工具,是要翻墙的。当然有离线包可用,具体可以网上搜索。)

 IOS的打开Safari的developer下。

   

   这是因为cordova的webView都已经开放了远程调试,

 如果是自己的加的webView,要进行远程调试

Android:

在调试WebView需要满足安卓系统版本为Android 4.4+已上。并且需要再你的APP内配置相应的代码,在WebView类中调用静态方法setWebContentsDebuggingEnabled,如下:

if (Build.VERSION.SDK_INT >=Build.VERSION_CODES.KITKAT) {  
  
   WebView.setWebContentsDebuggingEnabled(true);  
  
}

IOS:

  利用WebView隐含的一个API

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
  // ......
  [NSClassFromString(@"WebView") _enableRemoteInspector];
  // ......
}

不过这是个私有API,ARC关闭的情况下才能这么写,不然会报错。

微信:

  利用微信开发者工具进行远程调试,具体操作很简单

 2.远程调试可以debug那些web上看不出来,但是在在device上就出问题的情况

 1.weex安装完weex-toolkit

  $ npm install  -g  weex-toolkit
  就可以直接通过weex debug命令进行调试
  
2.比如下载的weex demo,进入根目录,运行
    weex debug examples
就会出现一些二维码页面,用playground app扫这个二维码,浏览器里出现如下页面

点击remotedebug按钮就可以进行远程调试了

3.React Native
在运行带RN的工程后,当前页面下ios模拟器通过cmd+D(真机可以通过摇一摇),android通过Menu按键,调出RN的开发者菜单,

4.electron和node调试(vscode中)

    "version": "0.2.0",
    "configurations": [
        {
            "type": "node",
            "request": "launch",
            "name": "Launch Program",
            "program": "${workspaceFolder}/app/templates/electron/node-util/encrypt.js"  //如果是debug当前文件,就是"${file}"

        },
    
      {
        "type": "node",
        "request": "launch",
        "name": "Launch via NPM",
        "cwd": "${workspaceFolder}/qogirShopClient-web/",
        "runtimeExecutable": "npm",
        "runtimeArgs": [
        "run-script",
        "dev"
        ],
        "port": 5858
      },
      {
        "type": "node",
        "request": "launch",
        "name": "Launch Webpack",
        "cwd": "${workspaceFolder}/qogirShopClient-web/",
        "program": "${workspaceFolder}/qogirShopClient-web/node_modules/webpack/bin/webpack.js",
        "env": {
          "NODE_ENV": "local"
        },
        "args": [
        "-p",
        "--config",
        "build/webpack.config.js",
        "u"
        ]
       },
        {
            "name": "Debug Main Process",
            "type": "node",
            "request": "launch",
            "cwd": "${workspaceRoot}/app/templates/electron",
            "runtimeExecutable": "${workspaceRoot}/app/templates/electron/node_modules/.bin/electron",
            "windows": {
                "runtimeExecutable": "${workspaceRoot}/app/templates/electron/node_modules/.bin/electron.cmd"
            },
            "args": [
                "."
            ]
        },
    {
      "type": "node",
      "request": "launch",
      "name": "Jest All",
      "program": "${workspaceFolder}/node_modules/.bin/jest",
      "args": [
        "--runInBand"
        ],
      "console": "integratedTerminal",
      "internalConsoleOptions": "neverOpen",
      "disableOptimisticBPs": true,
      "windows": {
        "program": "${workspaceFolder}/node_modules/jest/bin/jest",
      }
    },
    ]
}

 vscode的launch.json里添加配置,然后就可以在vscode里打断点调试node或者RN项目了

 "runtimeExecutable": "/Users/johnzhu/.nvm/versions/node/v13.2.0/bin/node" 可以切换所使用的node版本

  上面的第一个configure是调试node的,比如我的encrypt.js

  第二个是调试npm 脚本

  第三个调试webpack,并且加参数的

  第四个是调试electron的,目录那么长是因为是我自己的一个脚手架项目(https://github.com/johnzhu12/generator-rocky),electron的目录比较深

  各个配置的目录各不相同,对应自己项目的目录设置
 最后deBugger jest

 5.vscode调试karma

debugging Karma with Visual Studio Code
这里debug的断点一定要打在sourcemap里,大在源码里是不会被hit的
6. vscode 配置c/c++环境
  clang编译c,clang++编译c++

   launch.json和task.json
  

"configurations": [
        {
            "name": "clang++ build and debug active file",
            "type": "cppdbg",
            "request": "launch",
            "program": "${fileDirname}/${fileBasenameNoExtension}",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": false,
            "MIMode": "lldb",
            "preLaunchTask": "clang++ build active file"
        }
    ]
{
    "tasks": [
        {
            "type": "shell",
            "label": "clang++ build active file",
            "command": "/usr/bin/clang++",
            "args": [
                "-g",
                "${file}",
                "-o",
                "${fileDirname}/${fileBasenameNoExtension}"
            ],
            "options": {
                "cwd": "/usr/bin"
            }
        }
    ],
    "version": "2.0.0"
}

 c_cpp_properties.json

{
    "configurations": [
        {
            "name": "Mac",
            "includePath": [
                "/usr/local/include",
                "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/c++/4.2.1",
                "${workspaceFolder}/**"
            ],
            "defines": [],
            "macFrameworkPath": [
                "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/System/Library/Frameworks"
            ],
            "compilerPath": "/usr/bin/clang++",
            "cStandard": "c11",
            "cppStandard": "c++17",
            "intelliSenseMode": "clang-x64"
        }
    ],
    "version": 4
}

上面配置都自己试过,亲测有用
