此篇文章主要讲述获取服务器JSON接口数据，以便大家在今后的物联网信息时代，移动数据肯定都是需要网络数据的，那么就需要用一个分布集中，整体化的，规范性的创建所需的文件，同时方便以后维护；
分别为：M(model)，M(manager)，V(view)，C(cell)，C(controller);
具体程序如下：
一：YSMasonryManager.h
#import <Foundation/Foundation.h> #import "BaseManager.h" #import "YSMasonryModel.h" @protocol YSMasonryManagerDelegate <NSObject> -(void)networkSuccess:(YSMasonryModel *_Nullable)result; -(void)networkFail:(NSString *_Nullable)result; @end NS_ASSUME_NONNULL_BEGIN @interface YSMasonryManager : BaseManager @property(weak,nonatomic) id<YSMasonryManagerDelegate> delegate; -(void)getDeviceProile:(NSString *)limit Offset:(NSString *)offset; @end NS_ASSUME_NONNULL_END
二：YSMasonryManager.m
#import "YSMasonryManager.h"
@implementation YSMasonryManager
-(void)getDeviceProile:(NSString *)limit Offset:(NSString *)offset{
NSString *strUrl = [NSString stringWithFormat:@"%@api/internal/profile",DEVICE_BASE_URL];
//JSON
[PPNetworkHelper setRequestSerializer:PPRequestSerializerHTTP];
[PPNetworkHelper setResponseSerializer:PPResponseSerializerJSON];
//配置Jwt文件
[PPNetworkHelper setValue:USERJWTKEYS forHTTPHeaderField:@"Grpc-Metadata-Authorization"];
[PPNetworkHelper GET:strUrl parameters:@"" success:^(id responseObject){
YSMasonryModel *net = [YSMasonryModel mj_objectWithKeyValues:responseObject];
if(net.organizations.count>0){
if([self.delegate respondsToSelector:@selector(networkSuccess:)]){
[self.delegate networkSuccess:net];
}
}else{
if([self.delegate respondsToSelector:@selector(networkFail:)]){
[self.delegate networkFail:@"Get Fail!"];
}
}
} failure:^(NSError *error){
// NSError *newError = [NSError returnErrorWithError:error];
if([self.delegate respondsToSelector:@selector(networkFail:)]){
[self.delegate networkFail:@"cc"];
}
}];
}
@end

十三：所用到的常量一些定义：
Constants.h
#import <Foundation/Foundation.h> #define BASE_URL @"http://110.22.33/ilLoRaWan/" #define USERJWTKEYS @"eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiJsb3JhLWFwcC1zZXJ2ZXIiLCJhdWQiOiJsb3JhLWFwc"
至此！
以上详细的代码，主要就是mode数据层那，修改自己的json的返回数据，与一些字典类型的转换，就没其他的难点了。这样写的主要目的是，思路逻辑更清晰，后期维护也简单，分开着写代码更简洁。
以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持Devmax。
