在TST文件中添加条件逻辑以生成ts代码

Question

我有一个tst文件，该文件生成用于我的angular客户项目的ts文件。下面提供了tst和ts文件的代码。我需要放置一个条件语句以基于HttpRef类型生成return语句。我们有两种类型，即_phttp和_nghttp。如果您在下面看到tst文件的代码段，则尝试将if条件放入。我遇到的问题是它在ts文件中将if和else条件生成为完整块。我只需要生成基于if或else条件的返回条件。有人可以告诉我如何实现吗？

tst的片段

@Injectable()
export class $StubName {
       constructor($HttpImports) { } 
    $Classes(c=>c.BaseClass!=null&&c.BaseClass.Name=="ApiController"&&!c.Attributes.Any(a=>a.Name=="TsIgnore"))[
    $Methods(m=>!m.Attributes.Any(a=>a.Name=="TsIgnore"))[
    $name($Parameters[$name$IfOptional: $ParameterType][, ]): Observable<ApiResult<$ReturnType>> {

       if(this.$HttpRef =="_phttp")
         return true;
       else
        return this.$HttpRef.$HttpMethod(`/platform/$Url`,$RequestData||{},{observe: 'response'}).pipe(map((ret:HttpResponse<$ReturnType>) => <ApiResult<$ReturnType>>({  data: ret.body , originalResponse: ret })));
       }]
    $Methods(m=>m.Attributes.Any(a=>a.Name=="TsIgnore"))[
    static $name_url ($Parameters(p=>p.Type.IsPrimitive)[$name: $ParameterType][, ]):{method:string, url:string} {
        return {method: '$HttpMethod', url:`/platform/$UnescapedUrl`};
       }]]
}

生成的controller.ts文件的示例

如果看到下面的代码，则将在下面生成if和else块条件语句。我需要return true语句或else中提到的return语句。我不想看到if和else语句

 export class LocalisationProxy {
       constructor(private _nghttp: HttpClient, private _phttp: ProxyHttp) { } 


  getLatestTranslationFilesAndMerge(cultureId: number): Observable<ApiResult<any>> {

     if(this._nghttp =="_phttp")
     return true;
   else
        return this._nghttp.get(`/platform/localisation/${cultureId}`,null||{},{observe: 'response'}).pipe(map((ret:HttpResponse<any>) => <ApiResult<any>>({  data: ret.body , originalResponse: ret })));
   }
getTranslationDocument(documentId: number): Observable<ApiResult<any>> {

     if(this._phttp =="_phttp")
     return true;
   else
        return this._phttp.get(`/platform/localisation/document/${documentId}`,null||{},{observe: 'response'}).pipe(map((ret:HttpResponse<any>) => <ApiResult<any>>({  data: ret.body , originalResponse: ret })));
   }

    }
