我在失败块中获取 json 字符串
NSURL *url = [[NSURL alloc] initWithString:@"http://www.vinipost.com/Services/Update/UpdateService.asmx/GetPropSubType?"];
NSURLRequest *request = [[NSURLRequest alloc] initWithURL:url];
[AFJSONRequestOperation addAcceptableContentTypes:[NSSet setWithObject:@"text/html"]];
AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
NSLog(@"%@", JSON);
} failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
NSLog(@"Request Failed with Error: %@, %@", error, error.userInfo);
}];
[operation start];
输出:
