Question

我正在使用'request'模块与NODE.js合作：

有效：

var request = require('request');
request('http://www.site.com', function (error, response, body) {
  if (!error && response.statusCode == 200) {
    console.log(body);
  }
});

当我尝试包含参数时，它会崩溃！

var request = require('request');
request('http://www.site.com/index.php?action=y9sadf98yh', function (error, response, body) {
  if (!error && response.statusCode == 200) {
    console.log(body);
  }
});

Error: undefined is not a valid uri or options object.

    at Request._callback (nodeCloseSession/index.js:60:5)
    at Request.self.callback (/node_modules/request/index.js:148:22)

如何在NODE.js'request'模块中使用参数？

Answer 1

您可以尝试使用Requestify作为替代方案，一个用于nodeJS +的小而简单的HTTP客户端，它支持缓存..

要执行您的请求，请执行以下操作：

var requestify = require('requestify');

requestify.get('http://www.site.com/index.php?action=y9sadf98yh')
  .then(function(response) {
      // Get the response body (JSON parsed or jQuery object for XMLs)
      response.getBody();
  }
);

或者：

var requestify = require('requestify');

requestify.get('http://www.site.com/index.php', { 
    params: {
      action: 'y9sadf98yh'
    }
})
  .then(function(response) {
      // Get the response body (JSON parsed or jQuery object for XMLs)
      response.getBody();
  }
);

Answer 2

request('/www.site.com/', function (error, response, body) {
  if (!error && response.statusCode == 200) {
    console.log(body);
  }
});

使用用户代理获取参数值
