Question

向API发出请求

def update
    # ...    
    conn = Faraday.new(url: 'http://localhost:1111')
    conn.basic_auth('login', 'password')
    body = conn.get('/path/to/api', { guid: "123-456", pdf: 'true' } ) 
    # ...
  end

在另一面：

send_file(pdf_path, { filename: "#{name}.pdf", disposition: 'inline', type: 'application/pdf' })
send_file(docx_path, { filename: "#{name}.docx", disposition: 'inline', type: 'application/application/document' })

返回：

如何将其保存到文件中？
使用 carrierwave 。

request.document = body.body
document.save

但这不起作用
