KoaHub平台基于Node.js开发的Koa的简单包装到请求库的类似接口

Posted 2020-08-17

co-request

co-request promisify wrapper for request

co-request

Simple wrapper to the request library for co-like interface (node.js generator based code). You can use it with koa or co

To install simply run:

npm install co-request

Require co first, also it will work on node v0.11.7 and newest only.

You must run node with --harmony flag (--harmony-generators as well)

node --harmony simple.js

Simple example:

"use strict";
 
let co = require("co");
let request = require("co-request");
 
co(function* () {
  // You can also pass options object, see http://github.com/mikeal/request docs 
    let result = yield request("http://google.com"); 
    let response = result;
    let body = result.body;
 
    console.log("Response: ", response);
    console.log("Body: ", body);
}).catch(function (err) {
    console.err(err);
});

POST example:

"use strict";
 
co(function* () {
    let result = yield request({
        uri: "http://google.com",
        method: "POST"
    });
})();
To pipe request you should use small helper (thanks to greim):

function pipeRequest(readable, requestThunk){
  return function(cb){
    readable.pipe(requestThunk(cb));
  }
}
 
//..and then: 
 
  var value = yield pipeRequest(this.req, request({...}));

All methods of request listed in Request docs
