获取API请求超时？ [英] Fetch API request timeout?

问题描述

我有 fetch-api POST 请求：

   fetch(url, {
      method: 'POST',
      body: formData,
      credentials: 'include'
    })

我想知道这是什么默认超时？我们如何将它设置为特定值，如3秒或无限秒？

I want to know what is the default timeout for this? and how can we set it to a particular value like 3 seconds or indefinite seconds?

推荐答案

它没有指定的默认值; 规范根本不讨论超时。

It doesn't have a specified default; the specification doesn't discuss timeouts at all.

您可以为promises实现自己的超时包装器：

You can implement your own timeout wrapper for promises in general:

// Rough implementation. Untested.
function timeout(ms, promise) {
  return new Promise(function(resolve, reject) {
    setTimeout(function() {
      reject(new Error("timeout"))
    }, ms)
    promise.then(resolve, reject)
  })
}

timeout(1000, fetch('/hello')).then(function(response) {
  // process response
}).catch(function(error) {
  // might be a timeout error
})
