未设置NSURLSessionConfiguration HTTPAdditionalHeaders

Question

Authorization header在NSURLSessionConfiguration中设置，但不附加到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];

Answer 1

我在Swift中尝试了一下，它起作用了

    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

在NSURLSessionConfiguration document中，

HTTP是一个NSURLSession对象，旨在为您处理

协议的各个方面。因此，您不应修改以下headers：

授权

连接

主机

WWW-身份验证
