问题描述

授权标头在 NSURLSessionConfiguration 中设置，但它未附加到 NSURLSessionDataTask 。这是基础框架中的错误吗？

Authorization header is set in NSURLSessionConfiguration, however it is not attached to NSURLSessionDataTask. Is this a bug in Foundation framework?

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];

推荐答案

我在Swift中尝试这个并且它可以工作

I try this in Swift and it works

    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
