Design of the POST operation architecture of the iPhone development application ASIFormDataRequest

IPhoneDeveloping applicationsASIFormDataRequestPOST OperationArchitectureDesign is the content of this article.ASIFormDataRequestPOST OperationArchitectureDesign, methods defined by yourself. The content is mainly implemented based on code. Let's look at the detailed code.
