1.問題：Http請求蹋艺，返回208, 提示設(shè)備空間不足

2.原因：起初以為是硬盤空間沒了，其實(shí)不是。實(shí)際上是URLSession太多了
參考Stack Overflow:
It appears to get called when there are too many NSURLSessions created, reaching a limit of (in our tests) 600-700 sessions, which are not maintained or closed properly. The error started to get thrown since iOS 14, so it is interesting to see if there was a limit introduced.
3.解決方法：
因?yàn)槲业木W(wǎng)絡(luò)請求使用的是AFNetworking庫，起初是一個(gè)請求創(chuàng)建一個(gè) AFHTTPSessionManager的實(shí)例，請求多了檀训，自然就會(huì)有多個(gè)URLSession。
