  def index
    @articles = Article.all
  end

  def show
  end

  def new
    @article = Article.new

  end

    respond_to do |format|
      if @article.save
        format.html { redirect_to @article, notice: 'Article was successfully created.' }
        format.json { render :show, status: :created, location: @article }
      else
        format.html { render :new }
        format.json { render json: @article.errors, status: :unprocessable_entity }
      end
    end
  end

  def update
    respond_to do |format|
      if @article.update(article_params)
        format.html { redirect_to @article, notice: 'Article was successfully updated.' }

        format.html { render :edit }
        format.json { render json: @article.errors, status: :unprocessable_entity }

    end
  end

  def destroy
    @article.destroy
    respond_to do |format|
      format.html { redirect_to articles_url, notice: 'Article was successfully destroyed.' }
      format.json { head :no_content }
    end
  end

  private
    # Use callbacks to share common setup or constraints between actions.
    def set_article
      @article = Article.find(params[:id])
    end

    # Never trust parameters from the scary internet, only allow the white list through.
    def article_params
      params.require(:article).permit(:headline, :content, :location, :date)
    end
end

这是模型

class Article
  include Mongoid::Document
  field :headline, type: String
  field :content, type: String
  field :location, type: String
  field :date, type: DateTime
end

rails服务器说＆＃34;解析请求参数时发生错误＆＃34;并显示此错误ActionDispatch::ParamsParser::ParseError (822: unexpected token at '{'article': {'content': [u'\u0639\u064.....所以这里有什么问题。

我不知道这是否具有重要意义，但我通过抓取阿拉伯报纸文章来获取我的数据，我注意到我通过rails服务器创建它们的所有请求都失败了，所以尝试过发出一个卷曲请求，看看问题可能是什么

Answer 1

您的数据：

{'article': {'content':  ...

不是JSON。 JSON对象属性名称是字符串，strings in JSON use double quotes：

  

string 是零个或多个Unicode字符的序列，用双引号括起来，使用反斜杠转义。

您需要修复数据，以便它真的是JSON。

单引号＆＃34;字符串＆＃34;上的u前缀也是一个问题，也不是JSON。
