在我的 rails 应用程序上处理 api 测试时出现此错误。

错误是；

can't convert Symbol into Integer

app/controllers/api/v1/xml/messages_controller.rb:5:in `[]='
app/controllers/api/v1/xml/messages_controller.rb:5:in `create'

和

{"username"=>"info@skylinesms.com",
 "password"=>"[FILTERED]",
 "to"=>"256776582036",
 "from"=>"acacia",
 "message"=>"hello acacia",
 "format"=>:xml}

我怀疑问题是"format" => :xml在参数中。我如何阻止它被传递？

控制器是：

    def create
    @user = current_user
    @message = Message.new(params[:message])
    @message.user_id = current_user.id
    @message.status = 'Queued'
    if @message.save
        MessageWorker.perform_async(@message.id, lists, current_user.id)
        render json: {status: "success", to: @message.count, from: @message.from, 
                      balance: @user.balance, message: @message.message, 
                      time: @message.created_at} 
    else
        render status: 400 
    end
end

第 5 行是

@message = Message.new(params[:message])

回溯是

做了一个这样的快速修复

    def create
    @user = current_user
    @message = Message.new(params[:message])
    @message.message = params[:message][:text]
    @message.user_id = current_user.id
    @message.status = 'Queued'
    if @message.save
        MessageWorker.perform_async(@message.id, lists, current_user.id)
        render json: {status: "success", to: @message.count, from: @message.from, 
                      balance: @user.balance, message: @message.message, 
                      time: @message.created_at} 
    else
        render status: 400 
    end
end

现在得到这个错误

undefined method `[]=' for nil:NilClass

当您传递字符串而不是哈希时，您无法创建消息。

您的电话在您实际调用的第 5 行params[:message]返回：'hello acacia'

 @message = Message.new('hello acacia')

这是无效的。

Message 是一个 ActiveRecord::Model 所以它的初始化器需要一个散列。
