AFNetworking - 不缓存响应 [英] AFNetworking - do not cache response

问题描述

我正在使用此代码从服务器提取一个简单的 JSON 提要:

I'm using this code to pull a simple JSON feed from a server:

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    manager.responseSerializer = [AFJSONResponseSerializer serializer];

[manager GET:kDataUrl parameters:nil
 success:^(AFHTTPRequestOperation *operation, id responseObject) {
     NSLog(@"response: %@", responseObject);
 }
 failure:^(AFHTTPRequestOperation *operation, NSError *error) {
     NSLog(@"JSON DataError: %@", error);
 }];

它有效.但是，在我更改 kDataUrl 处的 JSON 文件并验证更改是在浏览器中进行后，当我再次运行该应用程序时，我仍然收到之前的响应.

It works. However, after I change the JSON file at kDataUrl, and verify that the change is made in a browser, when I run the app again, I still get the previous response.

似乎 AFNetworking 正在以某种方式缓存旧响应.我不想要这种行为.我想下载当前的提要.是否需要设置某种设置或参数来关闭缓存?

It seems that AFNetworking is somehow caching the old response. I do not want this behavior. I want to download the current feed. Is there some kind of setting or parameter I need to set to turn off caching?

推荐答案

长话短说，只需定义您的 AFNetworking 经理:

Make long story short, just define your AFNetworking manager:

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager.requestSerializer setCachePolicy:NSURLRequestReloadIgnoringLocalCacheData];

享受吧！
