iphone - 从 iPhone 应用使用 AFNetworking 上传视频

Question

我正在从我的 iPhone 应用程序向服务器发布视频文件。目前我正在使用 HTTP POST 方法。我想了解如何使用 AFNetworking 进行上传。希望有人能帮助我。

这是我现在使用的示例 HTTP 发布：

NSString *urlString =@"http://example.com/demo/upload_video";

NSMutableURLRequest *request= [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:@"POST"];

//userid 
[postbody appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"user_id\"\r\n\r\n%@", appDelegate.userid] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];

conn = [[NSURLConnection alloc] initWithRequest:request delegate:self];
if (conn) {
    webData = [[NSMutableData data] retain];
}

[httpClient enqueueHTTPRequestOperation:operation];您是否在代码末尾添加此内容？

使用以下代码作为示例：

NSURL *url = [NSURL URLWithString:@"http://api-base-url.com"];
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url];
NSData *imageData = UIImageJPEGRepresentation([UIImage imageNamed:@"avatar.jpg"], 0.5);
NSMutableURLRequest *request = [httpClient multipartFormRequestWithMethod:@"POST" path:@"/upload" parameters:nil constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) {
    [formData appendPartWithFileData:imageData name:@"avatar" fileName:@"avatar.jpg" mimeType:@"image/jpeg"];
}];

//如果您也想要进度报告，请使用以下代码：

AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
[operation setUploadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) {
    NSLog(@"Sent %lld of %lld bytes", totalBytesWritten, totalBytesExpectedToWrite);
}];
[httpClient enqueueHTTPRequestOperation:operation];
