使用Request模块时,我们如何从响应回调访问请求参数?
例如,可以通过循环列表传递以下“dog”(等等)值:
var u = require('util');
var url = "http://example.com/animals/%s";
request.get({uri: u.format(url, "dog")}, function (error, response, body) {
if (!error && response.statusCode == 200) {
//how could we access the value 'dog' here?
//something like this: console.log(uri.params.animal);
}
}

您可以使用js的闭包属性。
var u = require('util');
var url = "http://example.com/animals/%s";
var param = "dog";
request.get({uri: u.format(url, param )}, function (error, response, body) {
if (!error && response.statusCode == 200) {
//how could we access the value 'dog' here?
console.log(param);
}
}
