我正在尝试AFNetworking的新版本2.0，我得到上面的错误。知道为什么会这样吗?这是我的代码:
NSURL *URL = [NSURL URLWithString:kJSONlink];
NSURLRequest *request = [NSURLRequest requestWithURL:URL];
AFHTTPRequestOperation *op = [[AFHTTPRequestOperation alloc] initWithRequest:request];
op.responseSerializer = [AFJSONResponseSerializer serializer];
[op setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(@"JSON: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"Error: %@", error);
}];
[[NSOperationQueue mainQueue] addOperation:op];
我使用的是Xcode 5.0。
另外，下面是错误消息:
Error: Error Domain=AFNetworkingErrorDomain Code=-1016 "Request failed: unacceptable content-type: text/html" UserInfo=0xda2e670 {NSErrorFailingURLKey=kJSONlink, AFNetworkingOperationFailingURLResponseErrorKey=<NSHTTPURLResponse: 0xda35180> { URL: kJSONlink } { status code: 200, headers {
Connection = "Keep-Alive";
"Content-Encoding" = gzip;
"Content-Length" = 2898;
"Content-Type" = "text/html";
Date = "Tue, 01 Oct 2013 10:59:45 GMT";
"Keep-Alive" = "timeout=5, max=100";
Server = Apache;
Vary = "Accept-Encoding";
} }, NSLocalizedDescription=Request failed: unacceptable content-type: text/html}
我只是使用kJSONlink隐藏了JSON。这应该返回一个JSON。
我从Swift代码库中使用AFNetworking工作时遇到了类似的问题，所以我只是把这个留在远程情况下，有人像我一样不幸，必须在这样的设置中工作。如果你是，我觉得你，伙计，坚强点!
操作由于“不可接受的内容类型”而失败，尽管我实际上设置了一个包含有问题的内容类型值的Set acceptableContentTypes。
我的解决方案是调整Swift代码，使其更适合Objective-C，我想:
serializer.acceptableContentTypes = NSSet(array: ["application/xml", "text/xml", "text/plain"]) as Set<NSObject>
UIImage *image = [UIImage imageNamed:@"decline_clicked.png"];
NSData *imageData = UIImageJPEGRepresentation(image,1);
NSString *queryStringss = [NSString stringWithFormat:@"http://119.9.77.121/lets_chat/index.php/webservices/uploadfile/"];
queryStringss = [queryStringss stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];
[MBProgressHUD showHUDAddedTo:self.view animated:YES];
[manager POST:queryStringss parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData)
{
[formData appendPartWithFileData:imageData name:@"fileName" fileName:@"decline_clicked.png" mimeType:@"image/jpeg"];
}
success:^(AFHTTPRequestOperation *operation, id responseObject)
{
NSDictionary *dict = [responseObject objectForKey:@"Result"];
NSLog(@"Success: %@ ***** %@", operation.responseString, responseObject);
[MBProgressHUD hideAllHUDsForView:self.view animated:YES];
}
failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
[MBProgressHUD hideAllHUDsForView:self.view animated:YES];
NSLog(@"Error: %@ ***** %@", operation.responseString, error);
}];
