小程序导航传递参数及接受时JSON.parse不能解析的解决办法

在小程序有时要在不同页面时传递大量数据时需要把传递参数用JSON.stringify()函数转成字符，在目标页面中用JSON.parse函数接收：
例子:在原始页面点击跳转，携带一个对象moment

  previewImage: function (e) {
    let index = e.currentTarget.dataset.index;
    let moment = JSON.stringify(this.data.moment[index]);

    wx.navigateTo({
      url: '../moment_detail/moment_detail?moment=' + moment
    })
  },

在目标页面接收：

  onLoad: function(options) {
    let moment = options.moment
    
    this.setData({
      detail: JSON.parse(moment)
    })
  }

有时在解析接收对象时发生：

Unexpected end of JSON input;at pages/moment_detail/moment_detail page lifeCycleMethod onLoad function
SyntaxError: Unexpected end of JSON input

解决办法:

在JSON.stringify()之后将变量使用encodeURIComponent函数处理，encodeURIComponent() 函数可把字符串作为 URI 组件进行编码。在目标页面接收时用decodeURIComponent转回字符串。
即：

  previewImage: function (e) {
    let index = e.currentTarget.dataset.index;
    let monent = JSON.stringify(this.data.moment[index]);

    wx.navigateTo({
      url: '../moment_detail/moment_detail?moment=' + encodeURIComponent(monent)
    })
  },
