最近一直在看ASI请求数据这一块，都快蒙了都，其实我一直都是在懵懂的。

上个月，刚进公司，同事扔给了我一份代码，打开我懵掉了，完全看不懂，因为从来没用过ASI请求，

之前都是用的AFN，封装好的工具类，用起来很简单。

公司的代码一切都很好，就是请求这点儿，搞的不尽人意，可能同事也没弄过，好多请求的地方都没顾及到，

交给我的BUG，完全都是再请求结束，或者请求开始时的判断。

我问了好多朋友，同学，都说不曾用过，只是让我百度，goole  可是，没辙吖，找不到。

于是，自己摸索一天，找到了解决方案，

其实他的请求方法很简单：

- (void)setStartedBlock:(ASIBasicBlock)aStartedBlock

{

[startedBlockrelease];

startedBlock = [aStartedBlock copy];

}

- (void)setHeadersReceivedBlock:(ASIHeadersBlock)aReceivedBlock

{

[headersReceivedBlockrelease];

headersReceivedBlock = [aReceivedBlock copy];

}

- (void)setCompletionBlock:(ASIBasicBlock)aCompletionBlock

{

[completionBlockrelease];

completionBlock = [aCompletionBlock copy];

}

- (void)setFailedBlock:(ASIBasicBlock)aFailedBlock

{

[failureBlockrelease];

failureBlock = [aFailedBlock copy];

}

- (void)setBytesReceivedBlock:(ASIProgressBlock)aBytesReceivedBlock

{

[bytesReceivedBlockrelease];

bytesReceivedBlock = [aBytesReceivedBlock copy];

}

- (void)setBytesSentBlock:(ASIProgressBlock)aBytesSentBlock

{

[bytesSentBlockrelease];

bytesSentBlock = [aBytesSentBlock copy];

}

- (void)setDownloadSizeIncrementedBlock:(ASISizeBlock)aDownloadSizeIncrementedBlock{

[downloadSizeIncrementedBlockrelease];

downloadSizeIncrementedBlock = [aDownloadSizeIncrementedBlock copy];

}

- (void)setUploadSizeIncrementedBlock:(ASISizeBlock)anUploadSizeIncrementedBlock

{

[uploadSizeIncrementedBlockrelease];

uploadSizeIncrementedBlock = [anUploadSizeIncrementedBlock copy];

}

- (void)setDataReceivedBlock:(ASIDataBlock)aReceivedBlock

{

[dataReceivedBlockrelease];

dataReceivedBlock = [aReceivedBlock copy];

}

- (void)setAuthenticationNeededBlock:(ASIBasicBlock)anAuthenticationBlock

{

[authenticationNeededBlockrelease];

authenticationNeededBlock = [anAuthenticationBlock copy];

}

- (void)setProxyAuthenticationNeededBlock:(ASIBasicBlock)aProxyAuthenticationBlock

{

[proxyAuthenticationNeededBlockrelease];

proxyAuthenticationNeededBlock = [aProxyAuthenticationBlock copy];

}

- (void)setRequestRedirectedBlock:(ASIBasicBlock)aRedirectBlock

{

[requestRedirectedBlockrelease];

requestRedirectedBlock = [aRedirectBlock copy];

}

主要的就这些，我们常用的，就是：

//开始请求

- (void)setStartedBlock:(ASIBasicBlock)aStartedBlock

{

[startedBlockrelease];

startedBlock = [aStartedBlock copy];

}

//请求完成

- (void)setCompletionBlock:(ASIBasicBlock)aCompletionBlock

{

[completionBlockrelease];

completionBlock = [aCompletionBlock copy];

}

 //请求失败

- (void)setFailedBlock:(ASIBasicBlock)aFailedBlock

{

[failureBlockrelease];

failureBlock = [aFailedBlock copy];

}

所以，希望可以帮到大家都ASI的了解。
