Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
The existing stock market software usually adopts the same data interface, needs to use different fields in different scenes, but transmits the same fields through the same data interface, thereby transmitting a large number of unnecessary fields.
In order to solve the above problems, as shown in fig. 1, the present invention provides an extensible method for transmitting and displaying stock market data, which uses an Interface Description Language (IDL) file to define a protocol field of the stock market data and define an enable bit setting Interface, and then uses a translator to translate the IDL file into source codes of various programming languages. The source code defines the enable bit of each field, and defines the enable bit of each field to set the function, so that the code can call the function conveniently to set whether the field is transmitted on the network. The enable bits correspond to the bits of the byte, so that each byte may contain 8 enable bits. If 32 fields are included in the data returned by a certain interface, but in a certain scene, I only need to use 4 fields. Then the remaining 28 enable bits are turned off when requested by the client. The server side obtains the enable bit after the request of the receiving end, and only returns the corresponding 4 fields according to the setting state of the enable bit when the server side returns data, thereby greatly saving the flow.
Specifically, as shown in fig. 1, the present invention provides an extensible stock market data transmission display method, including:
s1, defining a protocol file by adopting an interface description language, wherein the protocol file comprises protocol fields of stock market data;
IDL is an abbreviation of Interface Description Language, refers to Interface Description Language, is a part of CORBA specification, and is the basis of cross-platform development. IDL is a computer language used to describe the interfaces of software components. IDLs describe interfaces in a neutral way so that objects running on different platforms and programs written in different languages can communicate with each other; for example, one component is written in C + + and another component is written in Java. IDLs are typically used to remotely invoke software. In this case, object components on different operating systems are typically called by the remote client terminal, and may be written in different computer languages. The IDL establishes a bridge for communication between two different operating systems.
Specifically, in the embodiment of the present invention, the stock market data may be described by IDL, for example, IDL description language is defined:
here we describe the most common data request in stock market transmission, namely to obtain real-time market for a batch of stocks. It can be seen that we set the precision for floating point numbers in the structure. And simultaneously, providing a function interface, and setting a unified request and response structure body which is used for assisting in transmitting the request enable bit in the follow-up process. And the precision is the display precision of the client.
In particular, a security quote may be defined in the protocol file, the security quote including fields of one or more of: the market price is the price of opening, closing, yesterday closing, highest price, lowest price, current price, stop price rising, stop price falling, volume of bargain, price of buying in five gear, quantity of buying in five gear, price of selling in five gear or quantity of selling in five gear. In the embodiment of the present invention, the protocol text contains fields shown in the above codes.
S2, translating the protocol file into a source code of a preset language by using a translator, wherein the source code defines the enabling bit of each protocol field and defines an enabling bit setting interface;
specifically, the IDL file defined in step S1 is translated using a translator pair, which is:

in the above example, we translate the defined IDL file into the source code of C + + language, and in the generated C + + file we define the following interfaces:
an enable bit setting interface, such as SetEnable _ sdtsecccode, sets whether the field is transmitted over the network;
an enable bit acquisition interface, GetEnable, for acquiring the enable bit of the whole structure;
coding and decoding other ports such as floating point number according to the mode of aligning to integer by a coding function and an Encode;
decoding a function, Decode, performing inverse operation on the floating point number to obtain an original value;
json coding, EncodeToJson, converting fields according to the precision of floating point numbers, and facilitating display of small programs and other web terminals;
json decoding, DecodeFromJson, converting Json type data into structure numerical values;
as can be seen from the above codes, the enable bit setting interface includes an enable bit setting function of the corresponding protocol field, and the client performs enable setting on the corresponding protocol field by using the enable bit setting function.
Meanwhile, an enable bit acquisition interface is also defined in the source code, and the server side acquires enable bit information of the data request by using the enable bit acquisition interface.
S3, the client end utilizes the enabling bit setting interface to enable and set the protocol field of the data to be requested, and initiates a data request to the server end, wherein the data request comprises the enabling bit information of the protocol field of the requested data;
specifically, when a client needs to request data from a server, a request and influence structure is defined by a translator, so that an enable bit is set. Specifically, the method comprises the following steps:
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；
}；
the Request structure body inherits the protocol Request and encodes and decodes the PMAP enabling bit, so that the client can conveniently transmit the enabling bit to the server. And the client encodes the enabling bit through an Encode function.
S4, the server receives the data request and obtains the enabling bit information, the enabling bit information is used for the server to determine the protocol field of the data requested by the client;
and after the server receives the data request of the client, the server acquires the PMAP from the network parameters through a Decode function. And obtaining an enabling bit of the whole structure body through an enabling bit obtaining function GetEnable, wherein the enabling bit identifies a protocol field of the client needing to request data. And when data is transmitted, determining transmission parameters according to the enable bit.
And S5, the server determines the data of the protocol field requested by the client according to the enabling bit information, and returns the data of the protocol field to the client.
And the server side returns the data requested by the client side to the client side.
Further, in the existing stock market software, the single-precision and double-precision data transmission fixedly uses 4 bytes and 8 bytes, and the flow is wasted for small-value floating point numbers. Specifically, for the stock market, fields such as opening price, closing price, yesterday closing price, highest price, lowest price, stop-and-go price, volume of bargain, etc., are all floating point types. However, floating point numbers are fixedly transmitted in a network by using 4 bytes or 8 bytes, but if integer transmission is adopted, 1 or 2 bytes are often required for transmission. Therefore, before transmitting data, the server side transmits the data according to the precision specified in the protocol, such as the value: 12.88, precision: 2, to convert to a reshape 1288, the number that would have required 8 direct transmissions now only needs 2 bytes. And after the coding and decoding functions of the server are automatically converted, sending the converted coding and decoding functions to the client. The client automatically converts the numbers into 12.88 according to the specified precision, and then restores the numbers.
In order to achieve the above object, as shown in the embodiments in steps S1 and S2, the method further defines the display precision of the floating point number of each protocol field in the protocol file, and the source code further includes an encoding function and a decoding function, where the encoding function is used to encode, at the server end, the corresponding floating point number according to the display precision of the floating point number of each protocol field in an alignment-to-integer manner to obtain an integer number, and the decoding function is used to decode, at the client end, the integer number back to the floating point number according to the display precision of the floating point number of each protocol field.
In addition, Json coding and decoding functions can be set, fields can be converted according to the precision of floating point numbers, and web end display of small programs and the like is facilitated. Specifically, in order to achieve the above object, the method further defines the display precision of the floating point number of each protocol field in the protocol file, the source code further includes a Json encoding function and a Json decoding function, the Json encoding function is used for encoding and converting the corresponding floating point number according to the display precision of the floating point number of each protocol field at the server end to obtain Json type data, and the Json decoding function is used for converting the received Json type data into a structure value at the client end so as to be displayed at the client end.
Furthermore, in the existing security software, the display precision of the floating point number of the client depends on the prior convention, and the subsequent expansion is not facilitated. In order to solve the problems, when the stock quotation is displayed, the stock quotation is displayed according to the precision of each field, and at the moment, the client can directly call the precision acquisition function from the IDL translation file to obtain the display precision of each field, so that the stock quotation is displayed on the client. Specifically, the method of the present invention further comprises:
and S6, after receiving and decoding the floating point number by the client, displaying the floating point number on the client according to the display precision.
