app store搜索接口

1.关键词搜索app列表

  通过pc端访问苹果官网，在搜索栏搜索app时，会发现官网返回的结果不是很完美，一部分app可以搜索到，例如：微信；还有一部分app通过关键词搜索不到，会返回一些技术支持的文章，例如：百度地图；目前我还没有从官网其它地方找到可以搜索app的入口。
  由于业务要求严格，这个搜索栏返回的结果不能很好的满足需求，在查询资料的过程中，发现appStore提供了对外访问iTunes的接口（https://affiliate.itunes.apple.com/resources/documentation/itunes-store-web-service-search-api/），只不过api举例不是特别详细，没有提供app搜索的样例，但是通过自己分析，一样可以拼装出搜索的url：
例如搜索关键词“微信”，返回结果是json字符串，解析json即可。
  URL：http://itunes.apple.com/cn/search?term=微信&media=software&limit=10

2.返回数据部分样例
