HTTP 请求客户端提供 axios 如界面在顶端 node-fetch。 。 。 .

安装

$ npm install gaxios

示例

import {request} from 'gaxios';
const res = await request({url: 'https://google.com/'});

fetch- 可兼容的 API 示例

我们提供一个客栈 fetch- 兼容的API也一样.

import {instance} from 'gaxios';
const res = await instance.fetch('https://google.com/');

无法在 res.data设置 {responseType: 'stream'} 或者说 .adapter gaxios 实例的默认或请求.

设置默认

Gaxios 支持在默认实例和附加实例上设置默认属性 。 这在向具有相同基础设置的同域提出许多请求时往往有用. 例如:

import {Gaxios} from 'gaxios';

const gaxios = new Gaxios();

gaxios.defaults = {
  baseURL: 'https://example.com'
  headers: new Headers({
    Authorization: 'SOME_TOKEN'
  })
}

await gaxios.request({url: '/data'});

注意设置默认值优先 相对于其他认证方法,即应用程序默认证书.

GaxiosResponse

这个 GaxiosResponse 对象延伸 fetch API的软件 Response 对象,并添加:

• config:请求所用的配置.
• data: 转变 .body,例如JSON,文本,阵列缓冲器,或更多.

请求选项

interface GaxiosOptions = {
  // The url to which the request should be sent.  Required.
  url: string | URL,

  // The HTTP method to use for the request.  Defaults to `GET`.
  method: 'GET',

  // The base Url to use for the request.
  // Resolved as `new URL(url, baseURL)`
  baseURL: 'https://example.com/v1/' | URL;

  // The HTTP methods to be sent with the request.
  headers: new Headers(),

  // The data to send in the body of the request. Objects will be serialized as JSON
  // except for:
  // - `ArrayBuffer`
  // - `Blob`
  // - `Buffer` (Node.js)
  // - `DataView`
  // - `File`
  // - `FormData`
  // - `ReadableStream`
  // - `stream.Readable` (Node.js)
  // - strings
  // - `TypedArray` (e.g. `Uint8Array`, `BigInt64Array`)
  // - `URLSearchParams`
  // - all other objects where:
  //   - headers.get('Content-Type') === 'application/x-www-form-urlencoded' (as they will be serialized as `URLSearchParams`)
  //
  // Here are a few examples that would prevent setting `Content-Type: application/json` by default:
  // - data: JSON.stringify({some: 'data'}) // a `string`
  // - data: fs.readFile('./some-data.jpeg') // a `stream.Readable`
  data: {
    some: 'data'
  },

  // The max size of the http response content in bytes allowed.
  // Defaults to `0`, which is the same as unset.
  maxContentLength: 2000,

  // The query parameters that will be encoded using `URLSearchParams` and
  // appended to the url
  params: {
    querystring: 'parameters'
  },

  // The timeout for the HTTP request in milliseconds. No timeout by default.
  timeout: 60000,

  // for writing tests and instrumentation

  };

  // The expected return type of the request.  Options are:
  // 'json' | 'stream' | 'blob' | 'arraybuffer' | 'text' | 'unknown'
  // Defaults to `unknown`.
  //
  // If the `fetchImplementation` is native `fetch`, the
  // stream is a `ReadableStream`, otherwise `readable.Stream`.
  //
  // Note: Setting 'stream' does not consume the `Response#body` - this can
  // be useful for passthrough requests, where a consumer would like to
  // transform the `Response#body`, or for using Gaxios as a drop-in `fetch`
  // replacement.
