AFNetworking 支持cookies的解决方案

发布时间：2023/12/8 编程问答 42 豆豆
生活随笔 收集整理的这篇文章主要介绍了 AFNetworking 支持cookies的解决方案 小编觉得挺不错的,现在分享给大家,帮大家做个参考.

   AFNetworking是支持cookies，只不过它把这个逻辑交给了iOS 底层的api处理了。

   多话不说了，很讨厌网上那些人云亦云的帖子，三人成虎！

  本次我们的项目重构，需要用到cookies，我直接给出解决方案吧：

（cookie使用支持的简单思路是：首次请求时，服务器取回cookies,然后每次请求时附加上cookie，如此反复即可，至于cookies中有啥内容，我们不用关注，服务器要就给她）

  我使用的是AFNetworking的AFHTTPClient进行网络访问的，我就直接在AFHTTPClient.h添加两个支持cookies的方法，一个是为post写的，另一个是为get写的。

1、在AFHTTPClient.h添加两个支持cookies的方法，每次请求时，都发送出本地cookies

12345 // add by block cheng- (void)blockGetPath:(NSString *)path     parameters:(NSDictionary *)parameters        success:(void (^)(AFHTTPRequestOperation *operation, id responseObject))success        failure:(void (^)(AFHTTPRequestOperation *operation, NSError *error))failure;

12345//add by block cheng- (void)blockPostPath:(NSString *)path      parameters:(NSDictionary *)parameters         success:(void (^)(AFHTTPRequestOperation *operation, id responseObject))success         failure:(void (^)(AFHTTPRequestOperation *operation, NSError *error))failure;

   其实现是：

  post实现是：

  对应的使用方法分别是：

2、每次请求返回时，保存cookie，以供以后使用
