(B5) Unicode character string types serialize：It is exactly to turn the call parameters for the character string that type is wchar_t*
Turn to IRpcArgument types.
Specifically, can be by call parameters when the data type of call parameters is Unicode character string types
Unicode character strings are copied in the m_wcharBuffer fields of serializing call parameters, and the m_ that will serialize call parameters
Type fields are arranged to RAT_WSTRING types.
(B6) array type serializes：The call parameters of array type are exactly converted into IRpcArgument types.
Specifically, when the data type of call parameters is array type, the array element of call parameters can be set
In the m_elementNum fields for putting serializing call parameters, and the m_type fields for serializing call parameters are arranged to

As an alternative embodiment, step S104, including：Data type based on call parameters, it will serialize
In call parameters write-in preset field.
In specific implementation process, when performing step S104, two kinds of situations can be divided into, a kind of is to work as call parameters
Data type is the situation of non-object type, and another kind is when the situation that the data type of call parameters is object type.
As an alternative embodiment, when the data type of call parameters is non-object type, it is described based on tune
With the data type of parameter, serializing call parameters are write in preset field, including (two kinds of situations of C1 and C2 hereinafter)：
(C1) if the data type of call parameters is non-array type, sequentially added in preset field the first byte and
Second byte, the information that the first byte is used in the m_type fields of saving sequence call parameters, the second byte are used to preserve
The parameter value of call parameters.
For example, if a call parameters are int types, in the args fields of serializing call parameters, the 1st
Byte is (i.e.：First byte) value is RAT_I32,4 bytes below are (i.e.：Second byte) value be the call parameters value.
(C2) if the data type of call parameters is array type, the first byte, are sequentially added in preset field
Three bytes and the second byte, the information that the first byte is used in the m_type fields of saving sequence call parameters, the 3rd byte
For the number of the array element in call parameters, the second byte is used for the parameter value for preserving call parameters.
For example, if the call parameters are array types, then, in the args fields of serializing call parameters,
1st byte is (i.e.：First byte) value is RAT_BLOB, 4 bytes below are (i.e.：3rd byte) be the array element
Number sizes, then followed by byte (i.e.：Second byte) be the array value.A for example, byte number for having 10 elements
Group, it is respectively that " 1,2,3,4,5,6,7,8,9,10 ", then the memory value for serializing call parameters is " 8 10 0001234
56789 10 ", wherein, the 1st " 8 " represent the value and represent an array type, and " 10 000 " below are 4 words
The integer value of section, wherein " 10 " represent the element number of the array, followed by all bytes (i.e.：“1 2 3 4 5 6 7 8
9 10 " content) is exactly the value of the array.
As an alternative embodiment, when the data type of call parameters is object type, it is described based on calling
The data type of parameter, serializing call parameters are write in preset field, including (i.e.：D hereinafter)：
(D) if the parameter type is object type, then, in the args fields of serializing call parameters, the 1st word
Section is still the information in the m_type fields of the serializing call parameters, and 4 bytes below are the element numbers of the structure,
Then, for each element in the object, if the element is non-array type, above-mentioned steps C1 is performed, if should
Element is array type, then performs above-mentioned steps C2, if the element is an object type again, carries out recurrence again and performs sheet
Step D, perform successively.
After recalls information is obtained based on this method, that is, the encapsulation to call parameters is completed, call end to pass through net
The recalls information is sent to the called terminal of remote process by road, and called terminal is after the recalls information is received, it is necessary to this
Recalls information decapsulates, and is exactly to carry out unserializing to serializing call parameters therein, so as to obtain the remote parties to be performed
The call parameters of religious name and correlation.
For example, called terminal is as follows to the decapsulation process of recalls information：
Called terminal can read the 1st byte in the args fields of recalls information (i.e.：First byte), for judging
The serializing call parameters are object type or non-object type, and when the byte is not equal to RAT_OBJECT values, representing should
It is a non-object type to serialize call parameters, then enters following step D1~D6 and carry out unserializing decoding, when the value
During equal to RAT_OBJECT values, it is an object type to represent the serializing call parameters, then enters following step E and carry out instead
Serializing decoding.
(D1) integer type：When it is RAT_I32 to serialize the m_type field values in call parameters, then the sequence is represented
Change call parameters be an integer type, then read args fields in the second byte (such as：4 words behind 1st byte
Section) content, so as to obtain the value of the call parameters.
(D2) byte Type：When it is RAT_I8 to serialize the m_type field values in call parameters, the serializing is represented
Call parameters are a byte Types, then read args fields in the second byte (such as：1 byte behind 1st byte)
Content, so as to obtain the value of the call parameters.
(D3) floating point type：When it is RAT_SINGLE to serialize the m_type field values in call parameters, the row are represented
Change call parameters be a floating point type, then read args fields in the second byte (such as：4 words behind 1st byte
Section) content, so as to obtain the value of the call parameters.
(D4) ascii character string type：When it is RAT_STRING to serialize the m_type field values in call parameters, generation
The table row call parameters are an ascii strings, then the content in args fields are read, untill reading 0, so as to obtain
Obtain the content of the ascii string.
(D5) Unicode character string types：It is RAT_WSTRING when serializing the m_type field values in call parameters
When, it is a Unicode character string to represent the row call parameters, then reads the content in args fields, be until reading 0
Only, so as to obtaining the content of the Unicode character strings.
(D6) array type：When it is RAT_BLOB to serialize the m_type field values in call parameters, represents rowization and adjust
An array type with the parameter, then read args fields in the second byte (i.e.：Such as：4 words after 1st byte
Section) content, obtain the number n of the array element, then read the content of this n byte, so as to obtain owning for the array
Element value.
(E) object type：When it is RAT_OBJECT to serialize the m_type field values in call parameters, then args is read
Second byte in field (such as：4 bytes behind 1st byte) content, obtain the member of inside n of the object type
Element, then, to this n element, the recursive process performed in above-mentioned steps D1~D6 successively, so as to be called to each serializing
Parameter carries out unserializing, obtains call parameters therein.
By this method, message encapsulation and the decapsulation during RMI are realized, due to this method
It is to be carried out based on binary form, so in network transmission process, required byte number is smaller, has higher biography
Defeated efficiency.
Technical scheme in above-mentioned the embodiment of the present application, at least has the following technical effect that or advantage：
In the embodiment of the present application, a kind of Information encapsulation method in remote procedure call is disclosed, including：Calling
When end carries out remote procedure call, it is determined that the data structure of the recalls information for calling the remote process, the data knot
Preset field is included in structure；Obtain the call parameters for calling the remote process；The call parameters are serialized,
Obtain serializing call parameters；The serializing call parameters are write in the preset field, obtain the recalls information.
When carrying out remote procedure call, recalls information is obtained using this method, then recalls information is sent to remote process by network
Called terminal, information transfer efficiency during remote procedure call can be greatly improved, entered in the prior art so as to solve
During row remote procedure call, the low technical problem of existence information efficiency of transmission.
