ASIHTTPRequest封装

不知道现在是否还有用ASI进行网络请求的,上一篇文章说到公司项目比较老,网络请求没有进行封装,每次发送网络请求是这样的

//声明一个属性
@property (nonatomic, strong) ASIHTTPRequest *attentionRequest;

//然后是这样
        [self.attentionRequest clearDelegatesAndCancel];
        self.attentionRequest = [[ASIHTTPRequest alloc] initWithURL:url];
        [self.attentionRequest setDefaultResponseEncoding:NSUTF8StringEncoding];
        self.attentionRequest.delegate  = self;
        self.attentionRequest.didFinishSelector = @selector(setAttentionFinsh:);
        self.attentionRequest.didFailSelector = @selector(setAttentionFail:);
        [self.attentionRequest startAsynchronous];

//下一步是实现方法
- (void)setAttentionFinsh:(ASIHTTPRequest *)request {
}
- (void) setAttentionFail:(ASIHTTPRequest *)request {
}
//最后dealloc时候清楚一下 不然有可能会崩溃
- (void)dealloc {
    [self.attentionRequest clearDelegatesAndCancel];
}

然后一个控制器网络请求多了的话,就是这样子的

@property (nonatomic, retain) ASIHTTPRequest * lunBoRequest;
@property (nonatomic, retain) ASIHTTPRequest * winRequest;
@property (nonatomic,retain) ASIHTTPRequest * eventRequest;
@property (nonatomic,retain) ASIHTTPRequest * allGameListRequest;
@property (nonatomic,retain) ASIHTTPRequest * hotGameListRequest;
@property (nonatomic,retain) ASIHTTPRequest * matchRequest;
@property (nonatomic,retain) ASIHTTPRequest * getGoldCoinRequest;
@property (nonatomic,retain) ASIHTTPRequest * yujirequest;
@property (nonatomic,retain) ASIHTTPRequest * betRequest;
@property (nonatomic,retain) ASIHTTPRequest * mallRequest;

下面要写的就是更多了,虽然每次都是复制,但是感觉程序员这样毕竟太low了,尝试封装了一个网络工具类

+ (ASIHTTPRequest *)getRequestWithUrl:(NSURL *)url success:(successBlock)success failedBlock:(ASIBasicBlock)failed {
    
    __weak ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
    __block successBlock successBlock = success;
    __block ASIBasicBlock failedBlock = failed;
    
    [request setDefaultResponseEncoding:NSUTF8StringEncoding];
    
    [request setCompletionBlock:^{
        
        NSDictionary *dict = [NSJSONSerialization JSONObjectWithData:request.responseData options:0 error:nil];
        
        if ([dict[@"code"] isEqualToString:@"0000"]) {
            if (successBlock) {
                successBlock(dict);
                successBlock = nil;
            }
        }else {
//            show message
            if ([dict[@"message"] length] > 0) {
                [[caiboAppDelegate getAppDelegate] showMessage:[dict valueForKey:@"message"]];
            }
        }
    }];
    
    [request setFailedBlock:^{
        if (failedBlock) {
            
            failedBlock();
            failedBlock = nil;
        }
    }];
    
    [request startAsynchronous];
    
    return request;
}

使用步骤简化成

1 创建属性
@property (nonatomic, strong) ASIHTTPRequest *attentionRequest;
2 发送网络请求
[self. attentionRequest clearDelegatesAndCancel];
self. attentionRequest = [NetWorkTool getRequestWithUrl:(NSURL *)url success:(successBlock)success failedBlock:(ASIBasicBlock)failed];
3 dealloc 销毁
- (void)dealloc {
    [self.attentionRequest clearDelegatesAndCancel];
}

基本可以不用每次都去复制了,block调用完成后,我会把block置空,所以你可以在block中使用self不会循环引用.
项目中尝试了一次自己的网络工具类,结果网络请求一直超时,拿着手机我给直接安装的就一切正常,但是通过二维码安装的就是网络超时,问了一下老大,老大说是ASI的blcok回调会有问题.我也不知道.只能使用代理重新封装一个

网络请求仍然用workTool完成,再创建一个util管理tool.然后通过runtime给NSObject添加一个util属性,你是用的时候只需要

  [self.netWorkNoDuplicateUtil getRequestAndCancleSameRequestWithUrl:url success:^(NSDictionary *dict) {

    } failedBlock:^{
        
    }];

是的,跟AFN一样简单了,你不用再去创建属性,也不用初始化,也不用在dealloc里面取消,我全都帮你做了,你只需要导入头文件直接发网络请求就可以了.使用self也没有问题,我还写了一使用SEL的方法,都可以使用.

这个地方是网络请求成功时候的调用 根据我们公司的json数据写的,用的时候需要修改一下

    if ([dict[@"code"] isEqualToString:@"0000"]) {
        if (self.successBlock && (self.callbackType == kCallbackTypeBlock)) {
            NSLog(@"成功了");
            self.successBlock(dict);
        }else if (self.successSelector && (self.callbackType == kCallbackTypeSelector)) {
            if ([self.controller respondsToSelector:self.successSelector]) {
                [self.controller performSelector:self.successSelector withObject:dict];
            }
        }
