如何从promise[duplicate]获取JSON

您可以等待答复:

fetch(url, options).then(async (response) => {
  const data = await response.json();
  console.log(data)
})

然后再添加一个:

fetch(...).then(resp => resp.json()).then(data => ...)

请注意 fetch

fetch(url)
  .then(resp => {
     // you'll need to supply the function that checks the status here
     if (http_response_ok(resp.status)) {
       return resp.json();
     } else {
       throw new Error(`Got back ${resp.status}`);
     }
  }).then(data => {
     // happy path
  }).catch(err => {
     // sad path
  });
