有没有办法计算异步函数被调用的次数？

Question

I have function that uploads files from an array of data links

What I would like to do is if data links array contains 3 files

const testLinks = 3; and async uploadImageData is fired three times I would like to console.log after uploadImageData is fired three times.

I am thinking of doing a count but all my testing has the count starting over everytime uploadImageData is fired.

.ts

async uploadImageData(formData: FormData) {
  const testLinks = 3;
  const uploadlink = answerAtachmentUrl;
  const headers = headerLink;
  const loading = await this.loadingController.create({
    message: 'Uploading Photos and Files...',
  });
  await loading.present();
  this.httpClient.post<any>( uploadlink + this.userToken, formData, 
  { 'headers':headers }
    ).pipe(
      finalize(() => { loading.dismiss();})
    )
    .subscribe(res => {
      if (res['success']) {
        setTimeout(() => { this.DeleteAllFiles(); }, 5000);
        this.presentToastPhoto('Photo sync success.');
      } else {
        this.presentToastPhoto('Photo upload failed.');
        let respFail = JSON.stringify(res);
        console.log("respFail", respFail);
      }
    });
    // console.log fires once after count and const testLinks both equal 3
}

"I am thinking of doing a count but all my testing has the count starting over evertime uploadImageData is fired." you didn't post what you tried but you probably did not make the counter a global variable. Your code is clearly part of a larger project so I just made this small test to show that it works with async functions. If it doesn't work, let me know.

 var count=0; async function uploadImageData() { const testLinks = 3; count++; console.log(count); if (count === 3){ console.log('count = 3'); } } uploadImageData(); uploadImageData(); uploadImageData(); uploadImageData();
