提取API请求超时？

Question

我有一个fetch-api POST要求：   fetch(url, {      method: 'POST',      body: formData,      credentials: 'include'    })我想知道默认的超时时间是多少？以及如何将其设置为3秒或不定秒的特定值？

使用中止语法，您将能够执行以下操作：

const controller = new AbortController();

const signal = controller.signal;

const fetchPromise = fetch(url, {signal});

// 5 second timeout:

const timeoutId = setTimeout(() => controller.abort(), 5000);

fetchPromise.then(response => {

  // completed request before timeout fired

  // If you only wanted to timeout the request, not the response, add:

  // clearTimeout(timeoutId);

})
