winform调用api接口问题

[qq_34818047]

winform调用api接口给app传递数据，接口那边写好了，以前都是用的webserver 没写过 api的。提交方式是get，求指点下

[姓小名白丶]

为啥要用winfrom调用API然后给APP数据？为毛不直接让APP调呢？

我们这边原有的分销系统 现在要分销商每销售一单开单完成后调用api给app那边传递数据。具体怎么考虑的是经理那边决定的，我只接到这个任务要实现。

WebClient.UploadData方法

首先你要理解，winform调用的接口是服务器借口，不是app 的接口。这个接口肯定是完成订单后，处理数据库数据，然后app 通过刷新数据去获取数据库中已处理的订单信息。 关于这个get/post 的.net实现代码网上有好多的。网页一般用ajax 实现或者 在后台拼接一个form，提交一下就可以了。winform可以采用form 拼接的方式。

提交数据用get，然后在QueryString里面传jsonstring，这接口我也是醉了....
