Fig. 1 shows the block chain of the invention i.e. signal architecture diagram of service platform system 100.In Fig. 1, block chain is
Service platform system 100 is based on cloud 110 and sets up comprising block chain, that is, service platform 120, multiple block chains 130,140,
150 and the storage equipment 170 and search engine 180 that schematically show.Wherein, block chain, that is, service platform system 100 can
To provide alliance's chain or privately owned chain service for user, also act as towards portal.In addition, block chain, that is, service platform 120 is also
The multiple functions such as data management, data analysis, search data are capable of providing, to meet the specific role of user and industry
Demand.Storage equipment 170 can store the index created according to block chain data and according to the block chain i.e. service platform 120
On the index that is created of platform information.
In block chain, that is, service platform system 100, since different types of block chain has different communication protocol, example
Such as, the block chain of fabric type uses customized RPC agreement etc. using the block chain of gRPC agreement, corda type, because
This, existing search engine be only able to achieve the primary foundation with a type of block chain communicate with to the data in the block chain into
Row retrieval.
In order to effectively solve the above problems, the content of present invention is provided for searching for data on block chain, that is, service platform
Method, equipment and corresponding computer readable storage medium.Combine Fig. 2-Fig. 4 description content institute according to the present invention first below
The disclosed method for searching for data on block chain, that is, service platform；Wherein, disclosed block chain, that is, service platform with
At least two block chains communication connection, and at least two blocks chain may belong to different types of block chain (such as, wherein
At least one block chain belongs to fabric type block chain, another block chain belongs to corda type block chain etc.).In Fig. 4
In show the specific implementation process of the disclosed method for searching for data on block chain i.e. service platform:
Before realizing illustrative methods shown in Fig. 4, the content of present invention is implemented first with Fig. 2, shown in Fig. 3 first
Example, second embodiment are obtained and are handled and the block chain information in block chain i.e. the block chain of service platform communication connection.Wherein,
The block chain information in the block chain communicated to connect with block chain, that is, service platform is obtained using first embodiment shown in Fig. 2,
It is specific as follows:
In step 210, the type with the block chain, that is, service platform communication connection block chain is identified.
Under normal conditions, different block chains be can have from the multiple block chains of block chain, that is, service platform communication connection
Type, for example, fabric, corda etc..
In a step 220, communication protocol associated with the block chain is determined based on the type of the block chain.Example
Such as, can at least be adapted to gRPC information transmission protocol for the block chain of fabric type, can for the block chain of corda type
To be adapted to customized RPC agreement etc..
In step 230, client associated with the block chain is stored on the block chain, that is, service platform
In the case where certificate, the block chain data in the corresponding block chain are obtained by the communication protocol, are specifically included:
Either block chain (such as, but not limited to, block in block chain, that is, service platform system 100 as shown in Figure 1
Chain 130) organizer when wishing that user is able to access that block chain data thereon, which sends out the client certificate of oneself
It is sent on block chain i.e. service platform 120.Either block chain in block chain, that is, service platform system 100 as shown in Figure 1
When the organizer of (such as, but not limited to, block chain 140) is not intended to user to be able to access that block chain data thereon, the block chain
The client certificate of oneself will not be sent on block chain i.e. service platform 120.
When block chain, that is, service platform 120 is using communication protocol associated with block chain 130 access block chain 130,
Due to storing the client certificate of block chain 130 on block chain, that is, service platform 120, the block chain, that is, service platform
120 can obtain block chain information from block chain 130.Wherein, the block chain data on block chain 130 both include private data
It also include public data.
Similarly it is found that when the block chain, that is, service platform 120 utilizes communication protocol associated with block chain 140 access region
When block chain 140, since the block chain, that is, service platform 120 is without the client certificate of memory block chain 140, the block
Chain, that is, service platform 120 can not obtain block chain information from block chain 140.
Utilize second embodiment pair shown in Fig. 3 and the block chain in block chain, that is, service platform communication connection block chain
Data creation index is specific as follows:
Step 310: by the block chain data conversion at webpage.
Specifically, by the block chain data conversion obtained using embodiment shown in Fig. 2 at webpage.
Step 320: obtaining one or more keywords by carrying out word segmentation processing to the webpage.
As an example, block chain data can use but be not limited only to be stored using key assignments (key/value) format,
Then carrying out the keyword of word segmentation processing generation to block chain data is also the data with key assignments format.Therefore, for alliance's chain
In the block chain of type for the different type of data, which further includes the first attribute as defined above, when
When first attribute of block chain data shows that the block chain data are private data, so that associated with the block chain data every
Affiliated block chain information in one index shows block chain belonging to the block chain data, can be had to illustrate the index only
There is the user of Service Ticket to search；When the first attribute of block chain data shows that the block chain data are public data, with
Affiliated block chain information in the block chain data associated each index is set as default value, to show that the index can be with
It is searched by any user.
Step 330: the content of each of one or more of keywords keyword, the block chain data is plucked
It wants, the affiliated block chain information of uniform resource location corresponding with the block chain data and the block chain data
Generate corresponding index.
Next, in the database by index generated storage.Wherein, the database and above-mentioned block chain service flat
Platform communication connection.
As a result, when keyword, which is, has the data of key assignments format, the format for each index which receives
Specific example it is as shown in the table:
| Keyword | Synopsis | Corresponding uniform resource location | Affiliated block chain information |
| KW1 | content_URL1 | URL1 | Block chain 130 |
Table one
The exemplary index that table one generates after showing any private data on block chain 130 by word segmentation processing,
In, the keyword in the index is KW1, and the actual storage address of the block chain data is URL1, and affiliated block chain information shows
The block chain data are from block chain 130 as shown in Figure 1, and the synopsis of the block chain data is content_
URL1.Above-mentioned indexed format is merely exemplary and not restrictive, and others can also be used in practical application scene
Indexed format is to meet the needs of of the invention.
In the concrete realization, one or more keywords are generated due to that can segment in either block chain data, it is every
One block chain data can correspond to one or more index with identical URL, in addition, different block chain data may divide
Word generates the index of multiple keywords having the same, it follows that can store in the database for storing index
A plurality of index and a plurality of index with identical URL, different keywords with same keyword, difference URL.
Alliances' chain such as such as Fabric, Corda is in all block chain data in the block platform chain of current mainstream
Whole data all do access privilege control.And in general, enterprise-level block chain usually using alliance's platform chain, to whole numbers
According to having done access authority.For example, an insurance sales system realized using block chain, the insurance valence in block chain
The information such as lattice, clause are desirable to be capable of retrieval and inquisition, without authorization；But other information, such as user information, transaction letter
The information such as breath, Claims Resolution record need to access permission control, are otherwise both unfavorable for protecting and customer privacy or are unfavorable for protecting
Protect the business secret of insurance company.
Therefore, for the different type of data in the block chain of alliance's chain type, the storage of index is specifically included:
Shown in embodiment as disclosed, in the case where block chain data are stored using key assignments format, the block
Chain data further include the first attribute as defined above.
For example, either block chain data can distinguish the first attribute of public data and private data comprising one, for example,
First attribute indicates that the block chain data are public data when being 0, and indicates the block chain data when first attribute is 1
For private data.Administrator is allowed real-time dynamicly to be adjusted among block chain operational process as a result, to improve number
According to Dynamic Maintenance.
It, will be with the block chain in the case where the first attribute of block chain data shows that the block chain data are public datas
In the open region of the associated index storage of data in the database.
It, will be with the block chain in the case where the first attribute of block chain data shows that the block chain data are private datas
The associated index of data is stored in the privacy area in the database.
It in the present embodiment, will be associated with the block chain data all when the first attribute of block chain data is 0
Index is stored in the open region of database.It, will be related to the block chain data when the first attribute of block chain data is 1
All indexes of connection are stored in the privacy area of database.
It is thus achieved that the differentiation for index stores, and then the access control to block chain data is realized, while just
The search to the private data in the block chain belonging to it is realized in block chain user.In addition, the organizer of block chain can be with
Some potential users are authorized to realize the search to the private data in the block chain.
