基于AFNetworking3.0的网络封装
1.创建名为HTTPMethod(自己随便起名字)的头文件
2.导入AFNetworking头文件(在github上下载最新版):
#import "AFNetworking.h"
3.在.h文件里声明类方法:
//参数解释:(1)urlString是你想请求的网址 (2)bodyDic是POST请求时的参数 (3)dataBlock是数据请求成功后用来回调数据的block
+ (void)getDataByString:(NSString *)urlString BodyDic:(NSDictionary *)bodyDic WithDataBlock:(void(^)(id data))dataBlock;
4.方法的实现:
+(void)getDataByString:(NSString *)urlString BodyDic:(NSDictionary *)bodyDic WithDataBlock:(void (^)(id))dataBlock
{
//(1).字符串的转码
urlString = [urlString stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet characterSetWithCharactersInString:urlString]];
//(2).创建管理者对象(session)
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
//(3).设置允许请求的类别
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"text/plain",@"text/json",@"application/json",@"text/javascript",@"text/html", @"application/javascript", @"text/js", nil];
//(4).开始请求
if (!bodyDic) {
//如果bodyDic为空就执行get请求
[manager GET:urlString parameters:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nonnull responseObject) {
dataBlock(responseObject);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(@"请求失败");
}];
}
else
{
[manager POST:urlString parameters:bodyDic success:^(NSURLSessionDataTask * _Nonnull task, id _Nonnull responseObject) {
dataBlock(responseObject);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(@"请求失败");
}];
}
}
