Question

我正在从远程位置读取CSV文件，然后解析它以存储到本地集合中，但是，我收到以下错误并且响应变为一些垃圾字符

Encoding::UndefinedConversionError: "\xD0" from ASCII-8BIT to UTF-8

以下是从远程位置获取csv的代码

    uri = URI.parse(site_url)
    data = {'token' => "xxxxxxxxxxxxxx"}
    req = Net::HTTP::Get.new(uri.path)
    req.set_form_data(data)
    http = Net::HTTP.new(uri.host, uri.port)
    if uri.scheme =='https'
      pem = File.read("#{Rails.root}/config/ca-certificates.crt")
      http.use_ssl = true
      http.cert = OpenSSL::X509::Certificate.new(pem)
      http.verify_mode = OpenSSL::SSL::VERIFY_PEER
    end
    response = http.start do |httpvar|
      httpvar.request(req)
    end
    if response.kind_of?(Net::HTTPRedirection)
      headers = {'Content-Type' => "text/csv; ecoding=utf-8" }
      uri = URI.parse(response['location'])
      response = open(uri).read
    end
     CSV.parse(response, headers: true, header_converters: :symbol) do |row|
      puts row
    end

Answer 1

来自Encoding error while writing data from excelfile to database (mysql)

尝试添加

# ecoding: utf-8

到你的.rb文件，或者使用magic_encoding gem

Answer 2

我认为当您在响应上调用CSV.parse时会发生此错误。在解析之前，您可以在response字符串上强制执行正确的编码，如下所示：

response.force_encoding(Encoding::UTF_8)
CSV.parse(response, headers: true, header_converters: :symbol) do |row|
  puts row
end
