Question

我尝试使用公共端点（例如：api.openweathermap.org/data/2.5/weather？lat = 35＆amp; lon = 139）而不是本地主机，同时配置dredd并运行命令来运行该工具但是我无法通过dredd连接到终点。它抛出错误：getaddrINFO EAI_AGAIN。但是当我尝试使用post man连接到端点时。我能够成功连接

调用本地或远程端点没有区别。

某些远程端点具有某种授权要求。

这是Dredd调用外部端点的示例：

dredd.yml配置文件片段

...
blueprint: doc/api.md
# endpoint: 'http://api-srv:5000'
endpoint: https://private-da275-notes69.apiary-mock.com

如您所见，唯一的变化是Dredd配置文件上的端点（使用Dredd init创建）。

但是，正如我提到的，有时您需要通过标头或查询字符串参数提供授权。

Dreed具有挂钩，可让您在每次交易前更改事物，例如：

您想在执行请求之前在每个URL中添加apikey参数。这段代码可以解决这个问题。

hook.js

// Writing Dredd Hooks In Node.js
// Ref: http://dredd.org/en/latest/hooks-nodejs.html

var hooks = require('hooks');

hooks.beforeEach(function(transaction) {
  hooks.log('before each');
  // add query parameter to each transaction here
  let paramToAdd = 'api-key=23456';
  if (transaction.fullPath.indexOf('?') > -1)
    transaction.fullPath += '&' + paramToAdd;
  else
    transaction.fullPath += '?' + paramToAdd;

  hooks.log('before each fullpath: ' + transaction.fullPath);
});

Github gist处的代码

将此hook文件保存在项目中的任何位置，然后运行Dredd传递挂钩文件。

dredd --hookfiles=./hoock.js

就是这样，执行后，日志将显示请求中使用的实际URL。

我们可以使用dredd工具连接到公共api端点而不是本地主机吗？
