前言：之前公司有個(gè)java牛人，和他一起做一個(gè)新的項(xiàng)目凉唐，結(jié)果他的接口協(xié)議，和我之前用過(guò)的完全不一樣，試了很多種方法读整，依舊請(qǐng)求不成功，最后通過(guò)其他途徑找到了解決方法强品，這里就不再?lài)Z叨這坎坷的路了屈糊。

先貼上接口協(xié)議
req包包含包頭head和包體body
{
“head”:{
“sessionID”:”xxx” //會(huì)話(huà)id（暫時(shí)不用）
},
“body”:{
}
}
body為請(qǐng)求具體參數(shù)

resp包包含包頭head和包體body
{
    “head”:{
        “rct”:0,                //返回錯(cuò)誤代碼 0表示正常，其他值為錯(cuò)誤
        “msg”:”正撤蛏危”    //錯(cuò)誤說(shuō)明
    },
    body:{
    }
}

body內(nèi)容為各個(gè)包具體返回信息

body里面就是與后臺(tái)交互的主要內(nèi)容昧诱。

下面是我封裝的網(wǎng)絡(luò)請(qǐng)求的類(lèi)，get和post

+(void)GET:(NSString *)URL parameters:(NSDictionary *)dic success:(httpRequestSuccess)success failure:(httpRequestFailed)failure{
    //創(chuàng)建配置信息
    NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
    //設(shè)置請(qǐng)求超時(shí)時(shí)間：5秒
    configuration.timeoutIntervalForRequest = 10;
    //創(chuàng)建會(huì)話(huà)
    NSURLSession *session = [NSURLSession sessionWithConfiguration: configuration delegate: nil delegateQueue: [NSOperationQueue mainQueue]];
    NSMutableURLRequest * request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@%@",HTTPRootPath,URL]]];
    //設(shè)置請(qǐng)求方式：POST
    [request setHTTPMethod:@"GET"];
    [request setValue:@"application/json" forHTTPHeaderField:@"content-Type"];
    [request setValue:@"application/json;charset=utf-8" forHTTPHeaderField:@"Accept"];
    
    //data的字典形式轉(zhuǎn)化為data
    NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dic options:NSJSONWritingPrettyPrinted error:nil];
    //設(shè)置請(qǐng)求體
    [request setHTTPBody:jsonData];
    
    NSURLSessionDataTask * dataTask =[session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
        if (error == nil) {
            NSDictionary *responseObject = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];
            success(responseObject);
        }else{
            NSLog(@"%@",error);
            failure(error);
        }
    }];
    [dataTask resume];
}
+(void)POST:(NSString *)URL parameters:(NSDictionary *)dic success:(httpRequestSuccess)success failure:(httpRequestFailed)failure{
    //創(chuàng)建配置信息
    NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
    //設(shè)置請(qǐng)求超時(shí)時(shí)間：5秒
    configuration.timeoutIntervalForRequest = 10;
    //創(chuàng)建會(huì)話(huà)
    NSURLSession *session = [NSURLSession sessionWithConfiguration: configuration delegate: nil delegateQueue: [NSOperationQueue mainQueue]];
    NSMutableURLRequest * request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@%@",HTTPRootPath,URL]]];
    //設(shè)置請(qǐng)求方式：POST
    [request setHTTPMethod:@"POST"];
    [request setValue:@"application/json" forHTTPHeaderField:@"content-Type"];
    [request setValue:@"application/json;charset=utf-8" forHTTPHeaderField:@"Accept"];
    
    //data的字典形式轉(zhuǎn)化為data
    NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dic options:NSJSONWritingPrettyPrinted error:nil];
    //設(shè)置請(qǐng)求體
    [request setHTTPBody:jsonData];
    
    NSURLSessionDataTask * dataTask =[session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
        if (error == nil) {
            NSDictionary *responseObject = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];
            success(responseObject);
        }else{
            NSLog(@"%@",error);
            failure(error);
        }
    }];
    [dataTask resume];
}

使用的時(shí)候

NSDictionary *parm = @{@"head":@{@"sessionID":@""},@"body":@{@"userID":user,@"page":[NSString stringWithFormat:@"%d",IndexPage]}};
        [NativeNetWork POST:@"getFirstPageList" parameters:parm success:^(id responseObject) {
            NSLog(@"%@",responseObject);
            NSDictionary * head = [responseObject objectForKey:@"head"];
            NSString *ReturnMessage = [head valueForKey:@"msg"];
            int ReturnCode = [[head valueForKey:@"rtc"] intValue];
            if (ReturnCode == 0) {
                NSDictionary * body = [responseObject objectForKey:@"body"];
                if (IsRefresh) {
                    DataArray = [NSMutableArray arrayWithCapacity:0];
                }
                for (NSDictionary * dic in body) {
                    QuestionModel * model = [[QuestionModel alloc] init];
                    [model setValuesForKeysWithDictionary:dic];
                    [DataArray addObject:model];
                }
                [ListView reloadData];
            }else{
                [self alertViewWithTitle:nil withMessage:ReturnMessage];
            }
        } failure:^(NSError *error) {
            [self alertViewWithTitle:@"獲取列表失敗" withMessage:@"請(qǐng)檢查網(wǎng)絡(luò)"];
        }];
    });
