作為iOS攻城獅都知道，網(wǎng)絡(luò)請(qǐng)求有一個(gè)著名的框架，那就是AFNetWorking,當(dāng)發(fā)起網(wǎng)絡(luò)請(qǐng)求時(shí)，我遇到了一個(gè)這樣bug
請(qǐng)求失敗--Error Domain=com.alamofire.error.serialization.response Code=-1016 "Request failed: unacceptable content-type: text/plain" UserInfo={com.alamofire.serialization.response.error.response=<NSHTTPURLResponse: 0x608000036220> { URL: https://api.weibo.com/oauth2/access_token } { status code: 200, headers {

分析
unacceptable content-type: text/plain 不接受內(nèi)容類型，換句話來(lái)說(shuō)AFN不支持解析這種格式，
那怎么解決的呢？AFNetworking為什么能夠解析服務(wù)器返回的東西呢?
因?yàn)閙anager有一個(gè)responseSerializer屬性.它只設(shè)置了一些固定的解析格式.其中不包含text/plain這種數(shù)據(jù)的格式.因?yàn)榻馕鰣?bào)錯(cuò)了.
我們來(lái)看一下AFNetworking解析格式的底層:
self.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript", nil];
沒(méi)有后臺(tái)提供的格式：text/plain,
那么，我們自己去修改，現(xiàn)在我發(fā)個(gè)gif圖看具體如何操作
