1.AFN baseurl出错

baseurl最后必须以 / 结束;

NSString *loginString = @"app/login";
NSURL *baseUrl = [NSURL URLWithString:@"http://192.12.12:8080/lyzh/"];
NSString *resultUrl = [[NSURL URLWithString:loginString relativeToURL:baseUrl] absoluteString];   
NSLog(@"resultUrl=%@",resultUrl);

打印结果：resultUrl=http://192.12.12:8080/lyzh/app/login

NSString *loginString = @"/app/login";
NSURL *baseUrl = [NSURL URLWithString:@"http://192.12.12:8080/lyzh"];   
NSString *resultUrl = [[NSURL URLWithString:loginString relativeToURL:baseUrl] absoluteString];  
NSLog(@"resultUrl=%@",resultUrl);   

打印结果：resultUrl=http://192.12.12:8080/app/login

结论：baseurl最后一个 / 之后的内容会被忽略掉，定义AFN baseurl时，必须以 / 结束；
