Network Programming-ASI -- (ASIHTTPRequest) Introduction, cnetwork programming Introduction Although ASIHTTPRequest is about tomorrow, I would like to summarize it a little and clarify my ideas to find out what she was able to do. 1. The ASI is based on the underlying CFNetworking framework and runs very efficiently. 2. prime partner: ASI + SBJson, which is used

First, the bottom realization1> AFN based on OC nsurlconnection and nsurlsession2> ASI 's underlying cfnetwork framework based on pure C language3> ASI has a higher operating performance than AFNIi. data processing for the return of the server1> ASI does not provide direct data processing to the server, directly returns the data\string2> AFN provides a variety of

What is the difference between ASI and AFN?1. Performance (Focus)* ASI based on the underlying cfnetwork framework* AFN based on nsurlconnection* Operating performance: ASI > ASN2. Processing server data1> AFN: Automatic parsing based on data returned by the server* The server returns JSON data, automatically converted to nsdictionary or Nsarray* The server retur

ASIHTTPRequest Although is the past, but still a little summed up, clear the idea, know this once she is able to do.1. ASI is based on the underlying cfnetworking framework and is highly efficient.2. Gold Partner: ASI + Sbjson, ASI is used for network requests, and Sbjson is used to parse the data returned by the server.Reference for use of 3.

The basic use of the ASI is described in the previous section, and the default usage is in the GET request mode. If you have any questions, please click here. A GET request is a parameter that is passed from a URL, and is generally intended to "ask" the server for the data it wants. And the post request, is generally the form data submission, the request data information in the request message, the background server receives the request information, w

The ASI cache is a feature of the ASI, as well as Apple's native Nsurlcache, which also provides a single-instance object [Asidownloadcache Sharedcache]1.ASI conditions for using caching1> must be a GET request2> request succeeded, status code is 2002. How a single request uses the ASI cache//Set URLNsurl *url = [Nsurl

JS magic Hall: ASI (automatic semicolon insertion mechanism) and Front semicolonI. Preface I will see the frontend Technical Expert of the People's Network in zhihu tonight-He Shijun-should I add points to JavaScript statements? The answer, let me once again see the elegant style of Daniel, really admire. However, the Pure admiration is not enough to return to such excellent texts. It is worthy of understanding the meaning of the texts and the princip

I, P, B group of synthetic image group, plus sequence start code and sequence first class data compose image sequence or MPEG 12 basic bitstream es (elementary Stream). Basic code stream can not be transmitted directly to the channel, it needs to be packaged and reused to form a single MPEG 12 transmission stream for transmission, video, audio and data basic stream ES is packaged into a series of unequal PES packets, each PES

In the first two sections, I introduced the ASI "Synchronous and Asynchronous" and "File upload" knowledge, if you have any questions, please click here. This section provides a simple example of downloading a file through the ASI.The interface is very simple, "start": Start downloading; "Stop": Pause download; Support for the continuation of the breakpoint.1. to define a request member property, make a strong reference to the

Objective Trust in C # and Java everyone knows that the semicolon is used as a punctuation (eos,end of statement), and must be semicolon, otherwise the compilation will not pass. But JavaScript has an ASI mechanism that allows us to omit semicolons. ASI mechanism is not to say that in the parsing process, the parser automatically adds a semicolon to the code, but says that the parser in addition to the sem

As the operation of the frequency upgrade machine needs automatic leveling function, so start to do this work. Hardware selection is incremental encoder, 100 pulses per revolution, and later learned that each timer of the STM32 Channel 1 and Channel 2 built-in Quadrature encoder module, can be used directly. Before the company engineers are using a timer to capture the pulse, and then self-processing, I loo
