飞信 发短信 流程
Sending SMS Flow of Fection
Scratch from youwang’s MFCFetionSDK ,
一点说明：我没有分析过飞信的协议，甚至没有研究过飞信的协议。故不能保证这些东西的准确性。这些程序员角度的流程是从MFCFetionSDK的代码中提取出来的。条件允许的话，可以自己写个飞信发短信的程序；显然，也可以使用现成的MFCFetionSDK。
可能会涉及到的一些技术细节：

------------------------------------------------------------------------
1. Get system config
1.0 Send post data(UTF-8) to: https://nav.fetion.com.cn/nav/getsystemconfig.aspx
1.1 Convert post data to UTF-8 code:
<config><user mobile-no="123456789" /><client type="PC" version="2.3.0230" platform="W5.1" /><servers version="0" /><service-no version="12" /><parameters version="15" /><hints version="13" /><http-applications version="14" /><client-config version="17" /></config>
1.2 Send post data(UTF-8 encoded) to above URL, HTTP POST
1.3 Receive post result (UTF-8 format)
1.4 Convert result to Unicode: system config xml
2. Parse the system config xml
2.1 get "ssi-app-sign-in" nodes
2.2 get "sipc-proxy" nodes
3. Get fection NO.
3.1 HTTP GET, URL= "ssi-app-sign-in".value + "?mobileno=123456789&pwd=111111"
3.2 get above GET result(UTF-8 format) xml
3.3 Convert GET result xml to Unicode
3.4 Parse xml and get "user" nodes and "uri" nodes and "user-id" nodes
3.5 Get "sip:{([0-9]+)}@fetion.com.cn" using RegEx
3.6 Get the fection NO.
4. SIPC
4.1 Init SIPC with "sipc-proxy".value
4.2 Parse the ip and port
4.3 Connect above ip and port using socket
5. Login
5.1 login xml data:
<args><device type="PC" version="6" client-version="2.3.0230" /><caps value="simple-im;im-session;temp-group" /><events value="contact;permission;system-message" /><user-info attributes="all" /><presence><basic value="400" desc="" /></presence></args>
5.2 Generate login request
Format("R %s SIP-C/2.0\r\nF: %s\r\nI: 1\r\nQ: 1 R\r\nL: %d\r\n\r\n"), domain, fetionNo, login xml length)
domain="fetion.com.cn"
fectionNO. from 3.6
5.3 Login data = login request + login xml
5.4 Convert to UTF-8 and send login data to SIPC using socket
5.5 Receive the response from above send using socket and convert from UTF-8 to Unicode, pause when find "\r\n\r\n", the HEADER
5.6 RegEx get matched "L: {([0-9]+)}", to parse out the buffer length
5.7 Get the left data(UTF-8) with the Length(above), convert to Unicode, the CONTENT
5.8 Above(HEADER+CONTENT) as the login response
5.9 Parse out "nonce=\"{([0-9A-Z]+)}\"" using RegEx
5.10 Calculate the NONCE
5.10.1 Get random number, convert to UTF-8 string, get MD5 Hash string in HEX, the nonceMD5
5.10.2 Format("%s:%s:%s", fectionNo, domain, pwd), convert to UTF-8 string, get MD5 Hash string in HEX, the INFO_STRING_MD5
fectionNO. from 3.6
domain="fetion.com.cn"
pwd=111111
5.10.3 Format(":%s:%s", nonce, nonceMD5), convert to UTF-8 string, the NONCE_STRING
nonce from 5.9
nonceMD5 from 5.10.1
5.10.4 INFO_STRING_MD5+NONCE_STRING, the LOGIN_STRING, MD5 of the LOGIN_STRING, the LOGIN_STRING_MD5
5.10.5 Format("REGISTER:%s", fetionNo), convert to UTF-8 string, get MD5 Hash string in HEX, REG_STRING_MD5
5.10.6 Format("%s:%s:%s", LOGIN_STRING_MD5, nonce, REG_STRING_MD5), convert to UTF-8 string, get MD5 Hash string in HEX, the nonceResponse
LOGIN_STRING_MD5 from 5.10.4
nonce from 5.9
REG_STRING_MD5 from 5.10.5
5.11 the second login, login xml data:
<args><device type="PC" version="6" client-version="2.3.0230" /><caps value="simple-im;im-session;temp-group" /><events value="contact;permission;system-message" /><user-info attributes="all" /><presence><basic value="400" desc="" /></presence></args>
5.12 Generate login request
Format("R %s SIP-C/2.0\r\nF: %s\r\nI: 1\r\nQ: 2 R\r\nA: Digest response=\"%s\",cnonce=\"%s\"\r\nL: %d\r\n\r\n", domain, fetionNo, nonceResponse, nonceMD5, login xml length)
domain="fetion.com.cn"
fectionNO. from 3.6
nonceResponse from 5.10
nonceMD5 from 5.10.1
5.13 Login data = login request + login xml
5.14 Convert to UTF-8 and send login data to SIPC using socket
5.15 Receive the response from above send using socket
6. Send SMS to target phone
6.1 Convert sms content to UTF-8 format
6.2 Format("M %s SIP-C/2.0\r\nF: %s\r\nI: 2\r\nQ: 1 M\r\nT: tel:%s\r\nN: SendSMS\r\nL: %d\r\n\r\n", domain, fetionNo, phone, sms length)
domain="fetion.com.cn"
fectionNO. from 3.6
phone: target phone number
sms length: byte count, not character count
6.3 Send login data to SIPC using socket
7. Logout
7.1 logout request data:
Format("R %s SIP-C/2.0\r\nF: %s\r\nI: 1 \r\nQ: 3 R\r\nX: 0\r\n\r\n", domain, fetionNo)
7.2 Send login data to SIPC using socket
Hope it helps~
