使用node Request包异步获取数据示例
const request = require('request');
class FetchData {
FetchData( url, params = {}, method = false, headers = false, json = true ){
let _json = json || false;
let _method = method ? 'POST' : 'GET';
let _headers = headers ? headers : {"content-type": "application/json"};
return new Promise( ( resolve, reject ) => {
request({
url: url,
method: _method,
json: _json,
headers: _headers,
body: JSON.stringify( params )
}, function( error, response, body ){
if (!error && response.statusCode == 200) {
resolve( body );
}else{
reject( error );
}
});
})
}
}
module.exports = new FetchData;
