iOS 报错"NSErrorFailingURLKey"的解决

错误打印如下

Error: Error Domain=com.alamofire.error.serialization.response Code=-1016 "Request failed: unacceptable content-type: text/plain" UserInfo={com.alamofire.serialization.response.error.response=<NSHTTPURLResponse: 0x17423e700> { URL: http://114.112.104.149:20012/app/consult/create/quick } { status code: 200, headers {

刚开始是认为AFN不支持"text/plain"样式, 但是自己在单例中已补充了这个类型, 补充的如下:

 manager.responseSerializer.acceptableContentTypes =[NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript", @"text/html", @"text/plain", @"multipart/form-data", @"image/jpeg", @"image/png", @"application/octet-stream", nil];

不是这个的原因.

但是, 在服务器未认证之前会有这个问题(我们公司的项目要实时认证才能访问服务器), 认证之后就不存在这个问题了, 那一定是认证的时候做了些什么事情, 所以我就去看认证的时候干了些什么, 结果我发现再认证的时候我加了这几句代码:

//增加这几行代码；
    AFSecurityPolicy *securityPolicy = [[AFSecurityPolicy alloc] init];
    [securityPolicy setAllowInvalidCertificates:YES];
    [manager setSecurityPolicy:securityPolicy];
    manager.responseSerializer = [AFHTTPResponseSerializer serializer];

就不在报这个错误论了, OK!

要加上安全策略.
