我正在为Google云功能编写代码。在这里，我想使用URL标准，包括URLSearchParams。我发现它们是Typescript dom lib的一部分，所以我已将它添加到我的tsconfig libs设置中。
但是当我编译和部署云功能时，我收到一个运行时错误，说没有定义URLSearchParams。
我错过了什么？我正在使用TS 2.6

这是我的配置：
{
"compilerOptions": {
/* Basic Options */
"target": "es6",
"module": "commonjs",
"lib": ["es6", "es7", "esnext", "dom"],
"sourceMap": true /* Generates corresponding '.map' file. */,
"outDir": "build" /* Redirect output structure to the directory. */,
"removeComments": true /* Do not emit comments to output. */,
/* Strict Type-Checking Options */
"strict": true /* Enable all strict type-checking options. */,
/* Additional Checks */
"noUnusedLocals": true /* Report errors on unused locals. */,
"noUnusedParameters": true /* Report errors on unused parameters. */,
"noImplicitReturns": true /* Report error when not all code paths in function return a value. */,
"noFallthroughCasesInSwitch": true /* Report errors for fallthrough cases in switch statement. */,
"plugins": [{ "name": "tslint-language-service" }],
"skipLibCheck": false
},
"include": ["src/**/*"],
"exclude": ["build"]
}
