【代码】AFNNetworking通过POST发送JSON类型的数据_iOS开发

仅仅是基本实现，根据需要进行修改。

大佬勿喷，有错误的地方还请在评论区指出，谢谢

RequestHelper.h

#import <Foundation/Foundation.h>
@interface RequestHelper : NSObject
//POST请求方法,afnetworking
+(void)postNetCallForStr:(NSString*)url paramArray:(NSMutableArray *) paramArray success:(void (^)(NSDictionary * respDic))success fail:(void (^) (NSError * error)) fail;
@end

RequestHelper.m

#import "RequestHelper.h"
#import "AFNNetworking.h"

@implementation RequestHelper

+(void)postNetCallForStr:(NSString*)url paramArray:(NSMutableArray *) paramArray success:(void (^)(NSDictionary * respDic))success fail:(void (^) (NSError * error)) fail{
    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    manager.requestSerializer = [AFJSONRequestSerializer serializer];
    manager.responseSerializer = [AFHTTPResponseSerializer serializer];
    NSString *urlStr=url;
    NSLog(@"===%@",urlStr);
    
    [manager POST:url parameters:paramArray success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        //请求成功返回数据 根据responseSerializer 返回不同的数据格式
        NSLog(@"responseObject-->%@",responseObject);
        NSDictionary *dic=[NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingMutableLeaves error:nil];
        
        if(success){
            success(dic);
        }
        
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        //请求失败
        NSLog(@"error-->%@",error);
        if(fail){
            fail(error);
        }
    }];
    
    
}
@end

调用示例

NSString *url=@"http://10.0.0.233:8848/User/login";
    NSDictionary* param= @{
        @"username":@"xxx",
        @"password":@"xxxxxxxx"
    };
    [RequestHelper postNetCallForStr:url paramArray:param success:^(NSDictionary *respDic) {
        NSLog(@"%@",respDic);

    } fail:^(NSError *error) {
        NSLog(@"%@",error);
    }];
