NSDictionary *params = [[NSDictionary alloc] initWithObjectsAndKeys:@"18678956721",@"phone",@"123123",@"password",nil];    //参数列表

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

    manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/plain"];     //报错的话修改此处，根据错误返回信息设置具体的内容

    [manager GET:str parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {    //GET/POST
