我有一个关于AFNetworking获取HTML网页的问题。
我有一个网址:
NSString *url = @"http://www.w3schools.com/";
我也有一个方法:
- (void)AFNReturnXMLString:(NSString *)string{
NSURL *url = [NSURL URLWithString:string];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
AFHTTPRequestOperation *op = [[AFHTTPRequestOperation alloc] initWithRequest:request];
// Make sure to set the responseSerializer correctly
op.responseSerializer = [AFXMLParserResponseSerializer serializer];
op.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];
[op setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
// Get XMLParser Object
NSXMLParser *XMLParser = (NSXMLParser *)responseObject;
[XMLParser setShouldProcessNamespaces:YES];
NSLog(@"%@", XMLParser);
// Leave these commented for now (you first need to add the delegate methods)
XMLParser.delegate = self;
[XMLParser parse];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"Error Fucking: %@", error);
}];
[op start];}
我已经使用了NSXMLParser委托。当我运行该方法时,变量&#34; qName&#34;仅显示根<html>
和<head>
标记,但不显示<body>
和<body>
的子节点。
我在块中使用了以下方法而不是NSXMLParser对象:
// Get HTML String
NSString *string = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
NSLog(@"%@", string);
该字符串显示所有页面内容。
以前有人遇到过这样的问题吗?
