关于iOS上的http请求还在不断学习，从早先的时候发现原来iOS的http请求可以自动保存cookie到后来的，发现ASIHttpRequest会有User-Agent，到现在发现竟然NSURLRequest默认不带USer-Agent的。添加方法：
#define USERAGENT @"Mozilla/5.0 (iPhone; CPU iPhone OS 5_1_1 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9B206 Safari/7534.48.3"
NSMutableURLRequest *restRequest = [NSMutableURLRequest requestWithURL:url
cachePolicy:NSURLRequestReloadIgnoringCacheData
timeoutInterval:30.0];
[restRequest setValue:USERAGENT forHTTPHeaderField:@"User-Agent"];
NSMutableURLRequest *restRequest = [NSMutableURLRequest requestWithURL:url
cachePolicy:NSURLRequestReloadIgnoringCacheData
timeoutInterval:30.0];
[restRequest setValue:USERAGENT forHTTPHeaderField:@"User-Agent"];
而我的情况要稍微复杂一点，发现服务器对于我请求的URL竟然进行了跳转，还需要再实现一个代理:
-(NSURLRequest *)connection:(NSURLConnection*)connection
willSendRequest:(NSURLRequest*)request
redirectResponse:(NSURLResponse*)redirectResponse{
NSMutableURLRequest *newReq = [request mutableCopy];
[newReq setValue:USERAGENT forHTTPHeaderField:@"User-Agent"];
return [newReq autorelease];
}
willSendRequest:(NSURLRequest*)request
redirectResponse:(NSURLResponse*)redirectResponse{
NSMutableURLRequest *newReq = [request mutableCopy];
[newReq setValue:USERAGENT forHTTPHeaderField:@"User-Agent"];
return [newReq autorelease];
}
that’s all
