ios - 未设置NSURLSessionConfiguration HTTPAdditionalHeaders

授权 header 在NSURLSessionConfiguration中设置，但未附加到NSURLSessionDataTask。这是Foundation framework中的错误吗？

NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
[configuration setHTTPAdditionalHeaders:@{@"Authorization":@"123"}];

// Initialize session with NSURLSessionConfiguration
NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
NSURLSessionDataTask *sessionTask = [session dataTaskWithRequest:request
                                        completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
}];

[sessionTask resume];

最佳答案

我在Swift中尝试了它并且有效

    var sessionConfig = NSURLSessionConfiguration.defaultSessionConfiguration()
    var xHTTPAdditionalHeaders: [NSObject : AnyObject] = ["X-test":"taly"]
    sessionConfig.HTTPAdditionalHeaders = xHTTPAdditionalHeaders
    let session = NSURLSession(configuration: sessionConfig)

    let task = session.dataTaskWithURL(url, completionHandler: {data, response, error -> Void in
