Question

我无法从GET方法中获取任何数据。我有一个名为job.ts的页面，在该页面中，我正在调用另一个提供程序/服务ts文件中的方法。

` // This part of the code is from the provider/service .ts file.
getSavedJobList(userId) {
    let headers = new HttpHeaders();
    headers.append('Content-Type','application/json');
    return this.http.get(this.db_url + 'savedjobList/' + userId,{headers: headers})
    .subscribe((data: any) => {
      console.log(data);
      return data 
    },(err: any) => console.log(err));
  }

// this part of the code is from the job.ts file
async getSavedJobs() {
    let id = await this.profileId();
    this.jobService.getSavedJobList(id).then((list: any) => {
      for (let job of list) {
        this.savedjobs.push(job);
      }
    }).catch((err: any) => {
      console.log('err in getting the saved jobs '+ err);
    });
  }
} `

这里没有采取任何行动。

为什么不将请求返回给job.ts并在此处订阅响应？试试这个：

getSavedJobList(userId) {
    let headers = new HttpHeaders();
    headers.append('Content-Type','application/json');
    return this.http.get(this.db_url + 'savedjobList/' + userId,{headers: headers});
  }

在job.ts

async getSavedJobs() {
    let id = await this.profileId();
    this.jobService.getSavedJobList(id).subscribe((list: any) => {
      for (let job of list) {
        this.savedjobs.push(job);
      }
    }).catch((err: any) => {
      console.log('err in getting the saved jobs '+ err);
    });
  }
}
