Question

我正在学习Ruby编程，并且正在构建一个API测试项目。我有一个特定站点的请求，并且正在使用Faraday gem。这是我的代码：

conn = Faraday.new
f_response = conn.post do |req|
  req.url 'https://api.abcxyz.vn/v2/tokens'
  req.headers['Content-Type'] = 'application/json'
  req.body = '{"email": "xxx@gmail.com","password": "abc123","grant_type": "password"}'
end

请求正常，我得到了成功的代码201。但是我不了解req.headers['Content-Type'] = 'application/json'的格式。它是哈希还是数组。因为如果我按以下方式替换代码：

request_headers = {"Content-Type" => "application/json"}
conn = Faraday.new
f_response = conn.post do |req|
  req.url 'https://api.abcxyz.vn/v2/tokens'
  req.headers = request_headers
  req.body = '{"email": "xxx@gmail.com","password": "abc123","grant_type": "password"}'
end

结果404错误代码。不好意思，请您帮我解决这个问题。另外，我还有另一个API，要求在标头字段中附加“ X-Access-Token”。如何将其输入有效载荷中。

Answer 1

req.headers是一个哈希，但是通过使用req.headers =，您将清除Faraday自动设置的所有标题，例如'User-Agent'。要添加新的标题，请执行与“ Content-Type”相同的操作：

conn = Faraday.new
f_response = conn.post do |req|
  req.url 'https://api.abcxyz.vn/v2/tokens'
  req.headers['Content-Type'] = 'application/json'
  req.headers['X-Access-Token'] = 'x-access-token-goes-here'
  req.body = '{"email": "xxx@gmail.com","password": "abc123","grant_type": "password"}'
end

如果在使用法拉第gem调用请求时替换有效负载中的值，则会收到404错误代码
