typescript - 在 Oclif CLI 中包含以空格分隔的参数

问题描述

我正在尝试构建一个使用 oclif 使用 Rest API 的 CLI。

我的代码如下：

import Command from '@oclif/command'
import axios from 'axios'

export class AggregatedCommand extends Command {
  static args = [
    {name: 'Area', required: true},
    {name: 'AreaName', required : true},
    {name: 'timeres', required: true},
    {name: 'Resolution', required: true},
    {name: 'ProdType',required: true},
    {name: 'ProductionType',required:true},
    {name: 'dateformat', required: true},
    {name: 'dateinput', required: true},
    {name: 'beforeformat', required: false},
    {name: 'format' , required: false}
  ]
  async run() {

    const axios = require('axios');
    const {args} = this.parse(AggregatedCommand); 
    //console.log(`${args.format}`);
    if (`${args.dateformat}`=='--date'){
     var splitted = `${args.dateinput}`.split("-", 3); 
    // console.log('http://localhost:8765/energy/api/AggregatedGenerationPerType/' +`${args.AreaName}` +'/' + `${args.ProductionType}` +'/' + `${args.Resolution}` +'/date/' + splitted[0] +'-' + splitted[1] + '-' + splitted[2]);
     if (`${args.format}`== "undefined" || `${args.format}`=="json"){
     const data= await axios.get('http://localhost:8765/energy/api/AggregatedGenerationPerType/' +`${args.AreaName}` +'/' + `${args.ProductionType}` +'/' + `${args.Resolution}` +'/date/' + splitted[0] +'-' + splitted[1] + '-' + splitted[2]);
         console.log(data.data);
     }
     else if (`${args.format}`=="csv") {
         const data= await axios.get('http://localhost:8765/energy/api/AggregatedGenerationPerType/' +`${args.AreaName}` +'/' + `${args.ProductionType}` +'/' + `${args.Resolution}` +'/date/' + splitted[0] +'-' + splitted[1] + '-' + splitted[2]+ "/format=" + `${args.format}`);
         console.log(data.data);
     }
     else console.log("Error 400: Bad Request");

    }

    else if (`${args.dateformat}`=='--month'){
         var splitted = `${args.dateinput}`.split("-", 2); 
             if (`${args.format}`== "undefined" || `${args.format}`=="json"){
     const data= await axios.get('http://localhost:8765/energy/api/AggregatedGenerationPerType/' +`${args.AreaName}` +'/' + `${args.ProductionType}` +'/' +  `${args.Resolution}` +'/month/' + splitted[0] +'-' + splitted[1]);
                 console.log(data.data);
            }

         else if (`${args.format}`=="csv") {
         const data= await axios.get('http://localhost:8765/energy/api/AggregatedGenerationPerType/' +`${args.AreaName}` +'/' + `${args.ProductionType}` +'/' + `${args.Resolution}` +'/month/' + splitted[0] +'-' + splitted[1] + "/format=" + `${args.format}`);
         console.log(data.data);
        }

        else console.log("Error 400: Bad Request");
    }

我正在尝试输入如下命令：

energy AggregatedGenerationPerType --area United Kingdom  --timeres PT15M --productionType AllTypes --year 2018

但是 oclif 和 typescript 不承认英国是一个参数，而是两个“United”和“Kingdom”。我该如何解决这个问题？

解决方案

由于您已经在示例调用中使用了标志，因此您应该切换到它们而不是 args。（见https://oclif.io/docs/flags）。

参数是传递给命令的位置参数

标志选项是传递给命令的非位置参数

例子：


export class AggregatedCommand extends Command {
  static flags = {
    area: flags.string(),
    timeres: flags.string(),
    ...
  } 

  async run() {
    const {flags} = this.parse(AggregatedCommand)
    if (flags.area) console.log('--area is set')
    if (flags.timeres) console.log('--timeres is set')
  }
}

然后你可以通过

energy AggregatedGenerationPerType --area "United Kingdom"  --timeres PT15M --productionType AllTypes --year 2018
