Overview

Process API can help you import data into a specific DCP through the form of interface docking. By adding the corresponding request parameters to the request according to the interface instructions, the system will return the processing results after the call. The request and response are encoded using the UTF-8 character set.

API Description
v2/process/create Create DCP Data
v2/process/update Update DCP data
v2/process/detail Query the latest DCP data
v2/process/fullDetail Get multilingual DCP data
v2/process/getList Query DCP data list
v2/attachment/upload Upload attachment
v2/attachment/info Query attachment information
v2/attachment/{fileHash} Download attachment

  • Create DCP data

    POST v2/process/create

Create DCP data. The interface has idempotent property, which is determined by the field of requestNo. If the field of requestNo is different, it will be treated as a new request. When calling this interface, you need to ensure that the operator has the create permission. For how to assign permissions, please refer to here. For permission comparison instructions, please refer to here. When orderStatus is FAILURE, developers need to add compensation mechanism. When the orderStatus is SUCCESS, you need to use the dataUUID or dataVID in the returned result to call Query the latest DCP data. The dcpStatus field in DCP details determines whether the call is successful. When the dcpStatus field is "SUCCESS",  it indicates that the call is successful. Otherwise, the call fails, and a compensation mechanism needs to be added. When uploading hash data(DCP type = DCP hash), please make sure the hash value(field: base.datalist.data) is hex string(sha256) , the length of which is 32 bytes.

  • Query DCP data list

    POST v2/process/getList

Query the DCP list and return the results in reverse order of creation time. This interface is implemented by the logic of page turning query. For example, if you need to query the latest 120 pieces of data on the chain, you can use page=1, size=100 and page=2, size=100 to request the interface respectively, and get the first 20 pieces of data in the second request. Similarly, you can also use page=1, size=60 and page=2, size=60 to request the interface to obtain data twice. If you want to further check the details, please use the query latest DCP data interface to query, currently only supports querying the latest updated record. For permission comparison instructions, please refer to here
