In above-mentioned example, the idl file of definition is translated into the source code of C Plus Plus by we, in the c++ file of generation
In, we define such as lower interface:
Interface is arranged in enable bit, and the field is arranged whether in network transmission in such as SetEnable_sDtSecCode；
Enable bit obtains interface, and GetEnable obtains the enable bit of total body；
Coding function, Encode, to other ports such as floating number according to snapping to integer mode encoding and decoding；
Decoding functions, Decode carry out inverse operation to floating number and obtain original value；
Json coding, EncodeToJson convert field according to floating number precision, the web terminals such as small routine are facilitated to show；
Json decoding, DecodeFromJson are converted into structural body numerical value from Json categorical data；
From above-mentioned code as it can be seen that enable bit setting interface includes the enable bit setting function of respective protocol field,
Client carries out enabled setting to respective protocol field using enable bit setting function.
Meanwhile also definition has enable bit to obtain interface in the source code, the server end utilizes the enable bit
Obtain the enable bit information that interface obtains the request of data.
S3, client using enable bit setting interface to needing the protocol fields of request data to carry out enabled setting,
And request of data is initiated to server end, it include the enable bit letter of the protocol fields of requested data in the request of data
Breath；
Specifically, when client is needed to server request data, request is defined by translater and influences structural body,
To which enable bit be arranged.Specifically:
struct QuoteReq:public Thoth::protocol::Message,public Thoth::
protocol::Request
{
public:
QuoteReq()
{
}
void SetRequestPMAP(const PMAP&xPMAP){xMAP.SetRequestPMAP(xPMAP)；}
void Encode(Thoth::protocol::BaseOutputStream&os)const
{
::Thoth::protocol::BaseOutputStream ostream(os.getBaseBuffer())；
ostream.SetRequestPMAP(xMAP)；
ostream.Write((uint16_t)0,vDtSecCode)；
}
void Decode(Thoth::protocol::BaseInputStream&is)
{
::Thoth::protocol::BaseInputStream istream(is.getBaseBuffer())；
istream.GetRequestPMAP(xMAP)；
istream.Read((uint16_t)0,vDtSecCode)；
}
public:
PMAP xMAP；
std::vector<std::string>vDtSecCode；
}；
struct QuoteRsp:public Thoth::protocol::Message,public Thoth::
protocol::Response{
public:
QuoteRsp()
{
}
void Encode(Thoth::protocol::BaseOutputStream&os)const
{
::Thoth::protocol::BaseOutputStream ostream(os.getBaseBuffer())；
ostream.Write((uint16_t)0,vQuote)；
}
void Decode(Thoth::protocol::BaseInputStream&is)
{
::Thoth::protocol::BaseInputStream istream(is.getBaseBuffer())；
istream.GetRequestPMAP(xMAP)；
istream.Read((uint16_t)0,vQuote)；
}
public:
std::vector<SecQuote>vQuote；
}；
Appealing structure body is inherited in Thoth::protocol::Request, which will carry out volume solution to PMAP enable bit
Code facilitates client transmitting enable bit to server-side.Client encodes enable bit by Encode function.
Request of data described in S4, the received server-side simultaneously obtains the enable bit information, and the enable bit information is used
Determine that the client needs the protocol fields of request data in the server；
After received server-side to the request of data of client, server-side is obtained from network parameter by Decode function
Get PMAP.The enable bit that function GetEnable obtains total body is obtained by enable bit, the enable bit identifies institute
State the protocol fields that client needs request data.When data are transmitted, configured transmission is determined according to enable bit.
S5, the server end determine the data of client institute request protocol field according to the enable bit information,
And the data of the protocol fields are returned to the client.
The requested data of the client are returned to the client by server end.
Further, in existing quotation software, the data transmission of single precision and double precision is fixed to use 4 bytes
With 8 bytes, flow is wasted very much for fractional value floating number.Specifically, in quotation, such as opening price, closing price,
Yesterday receives valence, highest price, lowest price, limit-up valence, limit down valence, exchange hand etc. field, is floating point type.But floating number is in network
It is fixed to generally require 1 or 2 byte transmission i.e. but if transmitting using integer using 4 bytes or 8 bytes when transmission
It can.So server-side is before transmitting the data, and according to the precision specified in agreement, such as numerical value: 12.88, precision: 2, it is converted into
Integer 1288, the original number for needing 8 directly to transmit only need 2 bytes now.The coding/decoding function of server-side is automatic
After conversion, it is sent to client.Number is automatically converted to 12.88, is restored by client according to specified precision.
To achieve the goals above, as shown in the embodiment in step S1 and S2, the method for the present invention is in the document of agreement
In there is also defined each protocol fields floating number display precision, further include having coding function and decoding letter in the source code
Number, the coding function be used for server end according to the display precision of the floating number of each protocol fields by corresponding floating number according to
It snaps to integer mode to be encoded to obtain integer, the decoding functions are used in client according to each protocol fields
The integer number decoder is returned floating number by the display precision of floating number.
In addition it can which Json coding/decoding function is arranged, field can be converted according to floating number precision, facilitate small routine etc.
Web terminal is shown.Specifically, to achieve the goals above, the method for the present invention there is also defined each agreement word in the document of agreement
The display precision of the floating number of section further includes having Json coding function and Json decoding functions in the source code, the Json
Coding function is for converting corresponding floating-point encoding according to the display precision of the floating number of each protocol fields in server end
To Json categorical data, the Json decoding functions are used to that the received Json categorical data to be converted into structure in client
Body numerical value in client to show.
Further, in existing security software, client floating number display precision is unfavorable for subsequent by making an appointment
Extension.To solve the above-mentioned problems, the method for the present invention is shown when showing quotation according to the precision of each field
Show, client can call precision to obtain function and obtain the display precision of each field directly from the translated document of IDL at this time,
To be shown in client.Specifically, the method for the present invention further include:
S6, the client are received and are decoded after obtaining floating number, shown according to the display precision in client described in
