iOS AFNetworking RequestBody请求

之前发送请求传给后台的参数都是通过requestParm的，而现在要改成走RequestBody的。

代码如下：

    
    // 请求头
    NSString *accessPath = @"http://119.254.126.188/app/userRegister/sendPhoneMsg";
    // 请求参数字典
    NSDictionary *params = @{@"mobie":@"W7YYWEtJaOxQSmTDqPb1EPtS4NqvVASpAgbSQP3f045XqXdwdIxf6f2aRXZD4%2BZj%2B28DkktLlV2JrgtiOWO7PQWarUZ2MhCeeZg%2FBTZzjQLzOMAkY5t%2ByQR0OxoziejIzlDOHhKMQoJxWDfp9t0aBkm3%2B%2BC%2BXQlVsSpmoCZboO4%3D", @"name":@"2"};

    NSLog(@"发送请求url=%@,params=%@",accessPath,params);

    AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];

    NSMutableURLRequest *request = [[AFJSONRequestSerializer serializer] requestWithMethod:@"POST" URLString:accessPath parameters:params error:nil];
    request.timeoutInterval = 10.f;
    [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    [request setValue:@"application/json" forHTTPHeaderField:@"Accept"];

    NSURLSessionDataTask *task = [manager dataTaskWithRequest:request completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {
        NSLog(@"-----responseObject===%@+++++",responseObject);
        if (!error) {
            if ([responseObject isKindOfClass:[NSDictionary class]]) {
                // 请求成功数据处理
            } else {

            }
        } else {
            NSLog(@"请求失败error=%@", error);
        }
    }];

    [task resume];
