在环回 4 中调用 API

如何解决在环回 4 中调用 API

我是环回 4 的新手。 我在文件 hello.controller.ts 中编写了一个 API，如下所示：

export class HelloController {
  constructor(
    @repository(StationMRepository)
    protected stationMRepository: StationMRepository) {}

     @post('/stationDetails')
      async stationDetails(@requestBody({
        content: {
          'application/json': {
            schema: {type: 'object'},},}) data: {
        searchkeyvaluePair:
        {
          miscellaneous: string,//relevantRollingStock: string,}): Promise<any> {
    
        console.log("Req.body:",data)
        var miscellaneous: string = data.searchkeyvaluePair.miscellaneous.trim()
        miscellaneous = miscellaneous.toLowerCase();
        var result: any = ''
        var resultLength: number = 0
        var stationData: string = ''
        var miscellaneousValid: boolean = !(miscellaneous == '' || miscellaneous == null || miscellaneous == undefined)
        if (miscellaneousValid) {
          stationData = `select public.stn_fullname_tsv_fn('${miscellaneous}')`
        }
        /*Calling tsvector Function*/
        result = await this.MetadataLettersRepository.execute(stationData)
        //console.log(result)
    
        /*To make the format of the data same for ts_vector and non ts_vector case*/
        resultLength = result.length
        //var resultModified: Array<any> = []
        var resultModifiednew: Array<any> = []
    
    
        if (resultLength > 0) {
          for (var i = 0; i < resultLength; i++) {
            // resultModified.push(result[i].letters_flex_search_tsvector)
    
            //Mapping from db format to Model format
            var objFormat: any = {}
            objFormat.stnCode = result[i].stn_fullname_tsv_fn.stn_code.trim()
            objFormat.stnFullname = result[i].stn_fullname_tsv_fn.stn_fullname.trim()
            objFormat.divCode = result[i].stn_fullname_tsv_fn.stn_divcode.trim()
            objFormat.divFullname = result[i].stn_fullname_tsv_fn.div_fullname.trim()
            objFormat.zoneCode = result[i].stn_fullname_tsv_fn.stn_zonecode.trim()
            objFormat.zoneFullname = result[i].stn_fullname_tsv_fn.zone_fullname.trim()
    
            console.log(objFormat)
            resultModifiednew.push(objFormat)
    
          }
        }
        console.log('ResultModified: ',resultModifiednew)
        console.log('ResultModified length:',resultModifiednew.length)
        return (resultModifiednew)
    
      }

}

我需要在 app.test.js 中调用这个 API 进行测试。代码如下：

it("Provides Station Details",() => {

    
    var stn = { data: { searchkeyvaluePair: { miscellaneous: "LKO" } } }

   
    const result = stationDetails(stn) //erroneous line
    console.log('Result: ',result)
    expect(result).to.have.status(200);
    console.log('Tested successfully..!!!')
   
  });

它给了我以下错误： 参考错误：stationDetails 未定义

请指导我应该用什么替换错误代码，以便正确调用 API。 提前致谢。
