Request为初始化网络请求数据的类

GET

如果你想发这样一个GET请求 http://test-leway.zjseek.com.cn:8000/api/goods/goodsList?type=1&pageSize=10&page=1&categoryId=-1&areaName=浙江

你可以这样定义一个GoodsListRequest

	#import "Request.h"
	@interface GoodsListRequest : Request
	@property(nonatomic,retain) NSString *type;
	@property(nonatomic,retain) NSNumber *page;
	@property(nonatomic,retain) NSNumber *pageSize;
	@property(nonatomic,retain) NSString *categoryId;
	@property(nonatomic,retain) NSString *areaName;
	@end
	
	
	#import "GoodsListRequest.h"
	@implementation GoodsListRequest
	/**
	 *  初始化 GoodsListRequest 的参数
	 */
	-(void)loadRequest{
	    [super loadRequest];
	    //self.HOST = @"test-leway.zjseek.com.cn:8000"; 不设置host 就采用宏定义的全局host
	    self.PATH = @"/api/goods/goodsList";
	    self.METHOD = @"GET";
	    self.type = @"1";
	    self.categoryId = @"-1";
	    self.areaName = @"浙江";
	    self.pageSize = @10;
	}
	@end
	
loadRequest方法里面初始化HOST，PATH，METHOD以及各种变量。EasyIOS会自动进行拼接为`http://test-leway.zjseek.com.cn:8000/api/goods/goodsList?type=1&pageSize=10&page=1&categoryId=-1&areaName=浙江`

POST

如果你想POST文件
你可以这样定义一个ImagePostRequest

	#import "Request.h"
	@interface ImagePostRequest : Request
	@property(nonatomic,retain) NSString *name;
	@end
	
	
	#import "ImagePostRequest.h"
	@implementation ImagePostRequest
	/**
	 *  初始化 GoodsListRequest 的参数
	 */
	-(void)loadRequest{
	    [super loadRequest];
	    //self.HOST = @"test-leway.zjseek.com.cn:8000"; 不设置host 就采用宏定义的全局host
	    self.PATH = @"/api/goods/goodsList";
	    self.METHOD = @"POST"; //设置为post
	    self.name = @"图片";
	    NSString *localPath1 = [NSString stringWithFormat:@"%@/%@",$.documentPath,@"face1.png"];
	    NSString *localPath2 = [NSString stringWithFormat:@"%@/%@",$.documentPath,@"face2.png"];
	    self.requestFiles = @{@"image1":[NSURL fileURLWithPath:localPath1],
	    					   @"image2":[NSURL fileURLWithPath:localPath2]};
	}
	@end

requestFiles方法里面返回一个文件字典。EasyIOS会自动进行识别上传

激活请求

如果你想快速的激活一个Request

	
	self.sceneModel.request.requestNeedActive = YES;

一个在SceneModel中使用的例子

-(void)loadSceneModel{
    [super loadSceneModel];
    [self.action useCache];
    self.userData = nil;
    
    @weakify(self);
    _request = [UserRequest RequestWithBlock:^{
        @strongify(self);
        if(self.request.userId.isNotEmpty){
            [self SEND_IQ_ACTION:self.request];
        }
    }];
    
    [[RACObserve(self.request, state) //监控 网络请求的状态
      filter:^BOOL(NSNumber *state) {
          @strongify(self);
          return self.request.succeed;
      }]
     subscribeNext:^(NSNumber *state) {
         @strongify(self);
         NSError *error;
         self.userData = [[UserEntity alloc] initWithDictionary:[self.request.output objectForKey:@"data"] error:&error];//Model的ORM操作，dictionary to object
     }];
}
