fetch 函数返回 Promise <pending>

2022-01-20 00:00:00 json fetch javascript

所以我的代码在这里返回一个 Promise，因为我使用的是 then 语法，所以我不知道为什么会这样:-??

So my code here return a Promise and since I'm using then syntax I don't know why that happens :-??

fetch('someurltoAJsonFile.json')
  .then(function(response) {
    console.log(response.json());});

推荐答案

node-fetch 库中的response.json() 也返回一个promise，改为尝试

response.json() in node-fetch library also returns a promise, instead try 

fetch('someurltoAJsonFile.json')
  .then(response => response.json())
  .then(data => {
    console.log(data)
  });

您可以在这里

返回的响应似乎不在有效的 json 中，所以为了完整起见，这里是文本代码

It seems that the returned response wasn't in the valid json, so for the sake of completeness here is a code for text

fetch('someurltoAJsonFile.json')
  .then(response => response.text())
  .then(data => {
    console.log(data)
  });
