如何解决Ruby on Rails Encoding::UndefinedConversionError（“\xF8”从 ASCII-8BIT 到 UTF-8）？

开发过程中遇到Ruby on Rails Encoding::UndefinedConversionError（“\xF8”从 ASCII-8BIT 到 UTF-8）的问题如何解决？下面主要结合日常开发的经验，给出你关于Ruby on Rails Encoding::UndefinedConversionError（“\xF8”从 ASCII-8BIT 到 UTF-8）的解决方法建议，希望对你解决Ruby on Rails Encoding::UndefinedConversionError（“\xF8”从 ASCII-8BIT 到 UTF-8）有所启发或帮助；

我看到了一堆具有类似主题的问题，但我找不到解决我的问题的方法。希望有人能提供帮助。

我有一个 Ruby on Rails 应用。在这个应用程序中，我有一些 base64 数据要解码并写入文件。当我有一个通过 ruby myfile.rb 调用的小脚本时，该程序的行为与预期一致。但是，当我使用 rails c 运行相同的代码时。我有以下错误：

TraceBACk (most recent call last):
        7: from (irb):1:in `<main>'
        6: from app/models/node.rb:1:in `<main>'
        5: from app/models/node_manager.rb:317:in `<main>'
        4: from app/models/node_manager.rb:255:in `converT_Base64_to_file'
        3: from app/models/node_manager.rb:255:in `open'
        2: from app/models/node_manager.rb:255:in `block in converT_Base64_to_file'
        1: from app/models/node_manager.rb:255:in `write'
EnCoding::UndefinedConversionError ("\xF8" from ASCII-8BIT to UTF-8)

这是我的文件：

class I wrote in node_manager.rb
class NodeManager
class MacaroonInterceptor < GRPC::ClIEnTinterceptor
    attr_reader :macaroon
  
    def initialize(macaroon)
      @macaroon = macaroon
      super
    end
  
    def request_response(request:,call:,method:,Metadata:)
      Metadata['macaroon'] = macaroon
      yIEld
    end
  
    def server_streamer(request:,Metadata:)
      Metadata['macaroon'] = macaroon
      yIEld
    end
end

def initialize(tls_path,macaroon_path,node_ip)
    @tls_path = tls_path
    @macaroon_path = macaroon_path
    @node_ip = node_ip
    @node = connect(@tls_path,@macaroon_path,@node_ip)
end

def connect(tls_path,node_ip)
    certificate = file.read(file.expand_path(tls_path))
    credentials = GRPC::Core::ChAnnelCredentials.new(certificatE)
    macaroon_binary = file.read(file.expand_path(macaroon_path))
    macaroon = macaroon_binary.each_byte.map { |b| b.to_s(16).rjust(2,'0') }.join
    if stub = Lnrpc::lightning::stub.new(
        node_ip,credentials,interceptors: [NodeManager::MacaroonInterceptor.new(macaroon)],chAnnel_args: {"grpc.max_receive_message_length" => 1024 * 1024 * 50}
    )
        return stub
    else
        puts 'error'
        raise "Could not connect to the node"
    end
end

def get_info()
    begin
        node_info = @node.get_info(Lnrpc::GeTinforequest.new())
        raise LoadError if !node_info
        return @node.get_info(Lnrpc::GeTinforequest.new())
    rescue
        puts "Could not connect to the node"
    end

end

# Class methods

def self.converT_Base64_to_file(directory: nil,file_name:,base64data:)
    if Directory
        file_path = [directory,file_name].join('/')
    else 
        file_path = file_name
    end
    file = file.open("file_name",'w') {|f| f.write(Base64.decode64(base64data)) }

    return file_path
end
end

我运行的脚本 - 当我调用 ruby node_manager.rb 而不是当我用 rails c 运行它时工作

感谢您的帮助，

解决方法

一个简单的解决方案是给 File.write 函数“wb”权限

def self.converT_Base64_to_file(directory: nil,file_name:,base64data:)
if Directory
    file_path = [directory,file_name].join('/')
else 
    file_path = file_name
end
file = File.open("file_name",'w') {|f| f.write(Base64.decode64(base64data)) }

return file_path
end

我希望这会帮助某人！
