反应天然 - 为什么取出卡奇会导致

Question

我使用fetch从服务器获取数据：

fetch(url, {
    method: 'GET',
    cache: 'no-cache'
});

有时它可以正常工作而无需任何缓存，有时会得到相同的结果（我确定数据已更改，并且我已经使用浏览器检查了该事实）。

似乎React Native在引擎盖下进行缓存，但是我该如何禁用它？

Answer 1

如果将缓存设置为reload，则应修复它。

这是缓存的一些用途。

  // Download a resource with cache busting, to bypass the cache
  // completely.
  fetch("some.json", {cache: "no-store"})
    .then(function(response) { /* consume the response */ });
  // Download a resource with cache busting, but update the HTTP
  // cache with the downloaded resource.
  fetch("some.json", {cache: "reload"})
    .then(function(response) { /* consume the response */ });
  // Download a resource with cache busting when dealing with a
  // properly configured server that will send the correct ETag
  // and Date headers and properly handle If-Modified-Since and
  // If-None-Match request headers, therefore we can rely on the
  // validation to guarantee a fresh response.
  fetch("some.json", {cache: "no-cache"})
    .then(function(response) { /* consume the response */ });
  // Download a resource with economics in mind!  Prefer a cached
  // albeit stale response to conserve as much bandwidth as possible.
  fetch("some.json", {cache: "force-cache"})
    .then(function(response) { /* consume the response */ });

注意：让我知道它是否不起作用，我将更新答案。
