Question

长期（好吧，3个月）读者，第一次发表的海报。我有一些客户端jquery AJAX请求的一些JSONP数据，我试图切换到http.request，所以我可以在Node.js服务器上使用它服务器端。

jQuery足够容易：JSfiddle here http://jsfiddle.net/gk0uttdu/，代码在这里：

  $.ajax({
    type: 'GET',
    url: 'http://www.mysupermarket.co.uk/Api.aspx?Command={"Output":"JSONP","Commands":[{"Name":"Basket","Params":{"BrandStores":["780"],"ProductPrices":{"920":["ASDA","Ocado","Sainsburys","Tesco","Waitrose"],"016555":["ASDA","Sainsburys","Tesco","Waitrose"]},"TrolleyItems":["920","52200","1017"],"TrolleyLinks":["780"]}}]}&banner=34',
    dataType: 'jsonp',
    success: function(json) {
        alert(JSON.stringify(json)); 
    }
});

然而，当我尝试使用Node的http模块重写此请求时，如下所示，它失败了403.我怀疑是因为我没有在任何地方设置dataType：JSONP。

var ajaxUrl = 'http://www.mysupermarket.co.uk/Api.aspx?Command={"Output":"JSONP","Commands":[{"Name":"Basket","Params":{"BrandStores":["780"],"ProductPrices":{"920":["ASDA","Ocado","Sainsburys","Tesco","Waitrose"],"016555":["ASDA","Sainsburys","Tesco","Waitrose"]},"TrolleyItems":["920","52200","1017"],"TrolleyLinks":["780"]}}]}&banner=34';

var req = http.request(ajaxUrl, function(res) {
  console.log('STATUS: ' + res.statusCode);
  console.log('HEADERS: ' + JSON.stringify(res.headers));
  res.setEncoding('JSONP');
  res.on('data', function (chunk) {
    console.log('BODY: ' + chunk);
  });
});

req.on('error', function(e) {
  console.log('problem with request: ' + e.message);
});

// write data to request body
console.log('data\n');
console.log('data\n');
req.end();

查看http文档并找不到如何设置它。还尝试了使用Matt的建议答案的Node请求模块，但未能使其工作。 Node HTTP request for Restful api's that return JSONP

这样做的正确方法是什么？感觉就像我一直撞在墙上几天，任何帮助都非常感激。

需要伪造用户代理。使用Node中的“请求”模块。这工作

request({
    headers: {
      'User-Agent': 'Mozilla/5.0 (X11; CrOS x86_64 6310.61.0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.94 Safari/537.36',
    },
    uri: 'http://www.mysupermarket.co.uk/Api.aspx?Command={"Output":"JSONP","Commands":[{"Name":"Basket","Params":{"BrandStores":["780"],"ProductPrices":{"920":["ASDA","Ocado","Sainsburys","Tesco","Waitrose"],"016555":["ASDA","Sainsburys","Tesco","Waitrose"]},"TrolleyItems":["920","52200","1017"],"TrolleyLinks":["780"]}}]}&callback=jQuery17102980830231681466_1418310018496&_=1418220018508',
    method: 'GET'
  }, function (err, res, body) {
    if (err) console.log(err)
    else console.log('body', body);

  });

正在努力使用http.request将jQuery JSONP查询转换为Node.JS查询
