我们在通过代理阅读器加载的商店中遇到不一致的数据损坏。
这取决于浏览器。
一直在桌面上的Chrome和Safari中正常运行。
在我们的两个测试iPhone上，它会间歇性地中断，具体取决于商店加载的数据，较大的数据量似乎会导致更多的中断。我们在JSON数据中看不到任何错误或模式。
症状：
似乎总是丢失的数据是start_time。
我们一直试图调试这个问题一段时间了，真的很难过。
感谢您提出任何有关原因的建议。

答案 0 :(得分：1)
经过多次敲击后，似乎Sencha Touch商店只能使用最多约10,000个字符，我猜8192 + json分隔符？
之后，它似乎开始为我们丢失部分数据。
其他人可以证实这一点吗？
答案 1 :(得分：1)
这不是Sencha Touch的特定问题：移动版Safari可以处理的Ajax响应大小有限制：请参阅Too large an AJAX response for mobile safari?
更新：显然这不是移动版Safari问题，这是一个蜂窝网络问题。一些网络将有助于“分页”Ajax调用 - 认为这是一个常规的网页下载。你能检查一下wifi网络是否仍然如此？
