Then result is sent to base station as needed, base station sends final result to the terminal of user, allows users to know it
Data message interested.
RESTful frameworks
REST full name are Representational State Transfer, and Chinese means declarative state transfer, what it referred to
It is one group of framework constraints and principle, if a framework meets REST constraints and principle, just it is referred to as we
RESTful frameworks.HTTP is example uniquely related to REST at present, so our REST described herein are also to pass through
The REST that HTTP is realized.
REST full name are the transfers of declarative state, and it is exactly resource to state refer to.Allow a resource can be identified, it is necessary to
There is individual unique mark, this unique mark is exactly URI (Uniform Resource Identifier) in Web.URI both may be used
To regard the address of resource as, the title of resource can also be regarded as.If some information do not use URI to represent, it
Cannot a resource at last, can only be resource some information.URI design should follow addressability principle,
With self descriptiveness, it is necessary to give association instinctively in form.
RESTFul frameworks should follow unified interface principle, and unified interface contains one group of limited predefined operation,
All it is the access that resource is carried out by using identical interface no matter which type of resource.Interface should use the HTTP of standard
Method such as GET, PUT, POST and DELETE, and follow the semanteme of these methods.
JSON
JSON (JavaScript Object Notation) is a kind of data interchange format of lightweight.It is based on
JavaScript（Standard ECMA-262 3rd Edition - December 1999）A subset.JSON is used
The text formatting of language is totally independent of, but also using the custom similar to C language family（Including C, C++, C#,
Java, JavaScript, Perl, Python etc.）.These characteristics make JSON turn into preferable data interchange language.It is easy to people
Read and write, while be also easy to machine parsing and generation (network transfer speeds are fast).

Token authentication generally use dynamic-password technique.So-called dynamic-password technique is changing to traditional static password technology
Enter, user will possess the Token that some things such as system is issued, and the numeral on Token is continually changing, and be taken with certification
Business device is synchronous, therefore it is also constantly to change that user, which signs in the password of system,（I.e. so-called " one-time pad "）.
Dynamic-password technique has two kinds of synchronization scenarios：Time synchronized, event synchronization.
1. time synchronized refers to that Token uses a seed of the time as dynamic password, server end by using
Time is as password caused by a seed certification Token.
2. event synchronization refers to when Token produces dynamic password every time using current counting as a seed, produce every time
After completing dynamic password, the counting can be incremented by automatically.Server end is equally using number as seed when verifying.
Token also preserves identical seed in token with the external world without any data communication, service end, same to use
With identical AES in token, identical encryption data is drawn, then obtains identical random cipher and is verified.Token
Random cipher must be bound with the account of client etc., just can provide whether password matches.When service end does certification, same password
Only allow verification once.
Hex files
Hex full name（Intel HEX）File is made up of the text for meeting Intel HEX file formats line by line
ASCII text file.In Intel HEX files, a HEX is included per a line and is recorded.These records are by corresponding machine language
The hexadecimal code of code and/or constant data numeral composition.Intel HEX files be generally used for transmission will be stored in ROM or
Program and data in person EPROM.Most of EPROM programmers or simulator use Intel HEX files.Existing programming is big
