自从我将AFNetworking从3.0.4更新到3.1.0后，我在下载文件时得到错误-999。我正在向服务器发送带有一些数据的发布请求，如果数据有效则会下载文件，否则将返回错误JSON。
这是代码：
AFSecurityPolicy *policy = [[AFSecurityPolicy alloc] init];
[policy setAllowInvalidCertificates:YES];
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
[manager setSecurityPolicy:policy];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
manager.responseSerializer = [AFCompoundResponseSerializer serializer];
[manager.requestSerializer setTimeoutInterval:DEFAULT_TIMEOUT];
[manager POST:[[BASE_URL stringByAppendingString:ACTION_UPDATE_DB] stringByAppendingString:API_KEY]
parameters:defaultData
progress:nil
success:^(NSURLSessionDataTask * _Nonnull task, id responseObject) {
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
}];
我已尝试更改为此，但结果相同。
AFSecurityPolicy* policy = [AFSecurityPolicy policyWithPinningMode:AFSSLPinningModeCertificate];
[policy setAllowInvalidCertificates:YES];
[policy setValidatesDomainName:NO];
