Ios 无法在中加载视频流

我不熟悉iOS开发

我想从webapi流式传输视频，这些文件是从我们的后端服务器流式传输的，这需要身份验证。它是授权HTTP头中基于密钥的身份验证集

我试过使用AVPlayer，但没有得到输出。在做了更多的研究之后，我发现customProtocol会更有用，所以我使用了customProtocol并尝试使用此代码，但customProtocol没有被调用

有人能帮我吗？我在哪里犯了错误

提前感谢您

这是我的customProtocol代码：

@implementation MyCustomProtocol

+ (BOOL) canInitWithRequest:(NSURLRequest *)request {
    NSURL* theURL = request.URL;
    NSString* scheme = theURL.scheme;
    if([scheme isEqualToString:@"customProtocol"]) {
        return YES;
    }
    return NO;
}

// You could modify the request here, but I'm doing my legwork in startLoading
+ (NSURLRequest *)canonicalRequestForRequest:(NSURLRequest *)request {
    return request;
}

// I'm not doing any custom cache work
+ (BOOL) requestIsCacheEquivalent:(NSURLRequest *)a toRequest:(NSURLRequest *)b {
    return [super requestIsCacheEquivalent:a toRequest:b];
}

// This is where I inject my header
// I take the handled request, add a header, and turn it back into http
// Then I fire it off
- (void) startLoading {
    NSMutableURLRequest* mutableRequest = [self.request mutableCopy];
    Constants *constants = [Constants sharedInstance];
    [mutableRequest setValue:[NSString stringWithFormat:@"Bearer %@",constants.access_token] forHTTPHeaderField:@"Authorization"];

    NSURL* newUrl = [[NSURL alloc] initWithScheme:@"http" host:[mutableRequest.URL host] path:[mutableRequest.URL path]];
    [mutableRequest setURL:newUrl];

    self.connection = [NSURLConnection connectionWithRequest:mutableRequest delegate:self];
}

- (void) stopLoading {
    [self.connection cancel];
}

// Below are boilerplate delegate implementations
// They are responsible for letting our client (the MPMovePlayerController) what happened

- (void) connection:(NSURLConnection *)connection didFailWithError:(NSError *)error {
    [self.client URLProtocol:self didFailWithError:error];
    self.connection = nil;
}

- (void) connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
    [self.client URLProtocol:self didLoadData:data];
}

- (void) connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response {
    [self.client URLProtocol:self didReceiveResponse:response cacheStoragePolicy:NSURLCacheStorageAllowed];
}

- (void) connectionDidFinishLoading:(NSURLConnection *)connection {
    [self.client URLProtocolDidFinishLoading:self];
    self.connection = nil;
}

如果您通过了带有url的身份验证标头，则可以使用以下代码

NSMutableDictionary * headers = [NSMutableDictionary dictionary];
[headers setObject:@"Your UA" forKey:@"User-Agent"];
AVURLAsset * asset = [AVURLAsset URLAssetWithURL:URL options:@{@"AVURLAssetHTTPHeaderFieldsKey" : headers}];
AVPlayerItem * item = [AVPlayerItem playerItemWithAsset:asset];
self.player = [[AVPlayer alloc] initWithPlayerItem:item];

它可能会起作用…试试看

如果您已经通过了带有url的身份验证头，那么您可以使用下面的代码

NSMutableDictionary * headers = [NSMutableDictionary dictionary];
[headers setObject:@"Your UA" forKey:@"User-Agent"];
AVURLAsset * asset = [AVURLAsset URLAssetWithURL:URL options:@{@"AVURLAssetHTTPHeaderFieldsKey" : headers}];
AVPlayerItem * item = [AVPlayerItem playerItemWithAsset:asset];
self.player = [[AVPlayer alloc] initWithPlayerItem:item];

这可能有用…试试看
