当我使用

wx.navigateTo({

      url: xxx?key1=value1,

    })

传值时，如果参数（value1）值长度比较长时，会出现参数被截断的情况。导致在跳转到的页面的onload函数中，无法正确json parse。

例如：

    跳转之前：

    {"status":4,"comment":"4","tags":[{"colum_set":1,"id":1,"name":"搞笑"},{"colum_set":1,"id":62,"name":"内涵"},{"colum_set":1,"id":55163,"name":"主版块"},{"colum_set":1,"id":68,"name":"漫画"},{"colum_set":1,"id":4670,"name":"涨姿势"}],"bookmark":"5","text":"别光看球，你知道NBA到底咋回事么？","image":{"medium":[],"big":["http://wimg.spriteapp.cn/ugc/2017/06/13/593f71abf2a1d_1.jpg","http://dimg.spriteapp.cn/ugc/2017/06/13/593f71abf2a1d_1.jpg"],"download_url":["http://wimg.spriteapp.cn/ugc/2017/06/13/593f71abf2a1d_d.jpg","http://dimg.spriteapp.cn/ugc/2017/06/13/593f71abf2a1d_d.jpg","http://wimg.spriteapp.cn/ugc/2017/06/13/593f71abf2a1d.jpg","http://dimg.spriteapp.cn/ugc/2017/06/13/593f71abf2a1d.jpg"],"height":22433,"width":750,"small":[],"thumbnail_small":["http://wimg.spriteapp.cn/crop/150x150/ugc/2017/06/13/593f71abf2a1d.jpg","http://dimg.spriteapp.cn/crop/150x150/ugc/2017/06/13/593f71abf2a1d.jpg"]},"up":"94","share_url":"http://a.f.budejie.com/share/25359529.html?wx.qq.com","down":13,"forward":6,"u":{"header":["http://tva4.sinaimg.cn/crop.0.0.996.996.50/e7f9e94djw8f6ursgyso3j20ro0rp0wy.jpg","http://tva4.sinaimg.cn/crop.0.0.996.996.50/e7f9e94djw8f6ursgyso3j20ro0rp0wy.jpg"],"uid":"19531820","is_vip":false,"is_v":false,"room_url":"","room_name":"Ms","room_role":"帮主","room_icon":"http://wimg.spriteapp.cn/ugc/2016/1101/gang_level_5.png","name":"臭宝蛋蛋 [Ms]"},"passtime":"2017-06-14 15:24:01","type":"image","id":"25359529"}

    跳转接收到的为：

    {"status":4,"comment":"4","tags":[{"colum_set":1,"id":1,"name":"搞笑"},{"colum_set":1,"id":62,"name":"内涵"},{"colum_set":1,"id":55163,"name":"主版块"},{"colum_set":1,"id":68,"name":"漫画"},{"colum_set":1,"id":4670,"name":"涨姿势"}],"bookmark":"5","text":"别光看球，你知道NBA到底咋回事么？","image":{"medium":[],"big":["http://wimg.spriteapp.cn/ugc/2017/06/13/593f71abf2a1d_1.jpg","http://dimg.spriteapp.cn/ugc/2017/06/13/593f71abf2a1d_1.jpg"],"download_url":["http://wimg.spriteapp.cn/ugc/2017/06/13/593f71abf2a1d_d.jpg","http://dimg.spriteapp.cn/ugc/2017/06/13/593f71abf2a1d_d.jpg","http://wimg.spriteapp.cn/ugc/2017/06/13/593f71abf2a1d.jpg","http://dimg.spriteapp.cn/ugc/2017/06/13/593f71abf2a1d.jpg"],"height":22433,"width":750,"small":[],"thumbnail_small":["http://wimg.spriteapp.cn/crop/150x150/ugc/2017/06/13/593f71abf2a1d.jpg","http://dimg.spriteapp.cn/crop/150x150/ugc/2017/06/13/593f71abf2a1d.jpg"]},"up":"94","share_url":"http://a.f.budejie.com/share/25359529.html

被截掉很长一段数据，无语。。。。。
