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];
}
}
