未设置NSURLSessionConfiguration HTTPAdditionalHeaders

Question

已设置授权标头NSURLSessionConfiguration,但未附加NSURLSessionDataTask.这是一个错误Foundation framework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

在NSURLSessionConfiguration 文档中,

NSURLSession对象旨在为您处理HTTP协议的各个方面.因此,您不应修改以下标头:

授权
