对于Node.js而言,我们需要使用node-fetch来在Node.js中使用Fetch。node-fetch是一个可使用fetch()API,通过npm进行安装,提供了一个轻量级的、兼容性友好的Fetch API扩展。 然而,在处理异步任务时,可能需要等待异步函数执行完成。在这种情况下,使用async/await可以帮助我们更好地处理异步任务。在Node.js中,使用async/aw...
如果我们使用 await,可以在函数或代码的任何地方使用它来获取 API 的响应,并在其上使用任何响应函数,例如 text() 或 json()。 例如:复制 // Typically we wrap await in an async function// But most modern browsers and Node.JS support// await statements outside of async functions now.async getAPI(...
4、接口调用-async/await用法 async/awati是ES7引入的心语法,可以更加方便的进行异步操作;async关键字用于函数上(async函数的返回值是Promise实例对象);await关键字用于async函数当中(await可以得到异步的结果) eg.(可以不使用then) 1 2 3 4 5 6 7 async function queryData(id){ const ret=await axios.get(...
importfetchfrom'node-fetch';constresponse=awaitfetch('https://httpbin.org/stream/3');try{forawait(constchunkofresponse.body){console.dir(JSON.parse(chunk.toString()));}}catch(err){console.error(err.stack);} In Node.js 12 you can also use async iterators to readbody; however, async itera...

Fetch is based on async and await. The example might be easier to understand like this: asyncfunctiongetText(file) { letx =awaitfetch(file); lety =awaitx.text(); myDisplay(y); } Try it Yourself » Use understandable names instead of x and y: ...
是指在Node.js环境中使用node-fetch库进行网络请求的一种方式。node-fetch是一个基于Fetch API的库,可以在Node.js中发起HTTP请求。 node-fetch的优势包括: 简单易用:node-fetch提供了简洁的API,使用起来非常方便。 支持Promise:node-fetch返回的是一个Promise对象,可以使用async/await或者.then()来处理请求结果,使...
