对请求的request添加一些参数

 

- (NSURLRequest *)addHeaderRequestWithUrl:(NSString *)urlStr
{
    NSMutableURLRequest *mutableRequest = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:urlStr]];
    NSString *token= [HelpModel getDataWithKey:TOKEN];
    if (token!=nil) {
        [mutableRequest setValue:[HelpModel getDataWithKey:TOKEN] forHTTPHeaderField:@"token"];
        [mutableRequest setValue:@"afsfsad" forHTTPHeaderField:@"User-Agent"];
        [mutableRequest setValue:@"iOSApp" forHTTPHeaderField:@"Request-From"];
        
    }
    return mutableRequest;
}
