当尝试将json值作为输入（值）传递给超级账本调用链代码中的特定键时，出现以下错误：

Error: chaincode argument error: invalid character ':' after array element
Usage:
  peer chaincode invoke [flags]

Flags:
  -C, --channelID string               The channel on which this command should be executed
      --connectionProfile string       Connection profile that provides the necessary connection information for the network. Note: currently only supported for providing peer connection information
  -c, --ctor string                    Constructor message for the chaincode in JSON format (default "{}")
  -h, --help                           help for invoke
  -n, --name string                    Name of the chaincode
      --peerAddresses stringArray      The addresses of the peers to connect to
      --tlsRootCertFiles stringArray   If TLS is enabled, the paths to the TLS root cert files of the peers to connect to. The order and number of certs specified should match the --peerAddresses flag
      --waitForEvent                   Whether to wait for the event from each peer's deliver filtered service signifying that the 'invoke' transaction has been committed successfully
      --waitForEventTimeout duration   Time to wait for the event from each peer's deliver filtered service signifying that the 'invoke' transaction has been committed successfully (default 30s)

Global Flags:
      --cafile string                       Path to file containing PEM-encoded trusted certificate(s) for the ordering endpoint
      --certfile string                     Path to file containing PEM-encoded X509 public key to use for mutual TLS communication with the orderer endpoint
      --clientauth                          Use mutual TLS when communicating with the orderer endpoint
      --connTimeout duration                Timeout for client to connect (default 3s)
      --keyfile string                      Path to file containing PEM-encoded private key to use for mutual TLS communication with the orderer endpoint
  -o, --orderer string                      Ordering service endpoint
      --ordererTLSHostnameOverride string   The hostname override to use when validating the TLS connection to the orderer.
      --tls                                 Use TLS when communicating with the orderer endpoint
      --transient string                    Transient map of arguments in JSON encoding

提供的json是有效的JSON字符串。数组元素的末尾没有任何“：”，但错误。有什么办法可以在PHP中解析

Answer 1

根据https://jsonlint.com，您的JSON无效，它返回：

Error: Parse error on line 41:
...: "AXXXXXXXXX",              "FATHER\'s NAME": "M
----------------------^
Expecting 'STRING', got 'undefined'

如果您替换这两个

"FATHER\'s NAME": "Mylari Rao",
"MOTHER\'s NAME": "Yeshoda",

通过

"FATHER\\'s NAME": "Mylari Rao",
"MOTHER\\'s NAME": "Yeshoda",

或

"FATHER's NAME": "Mylari Rao",
"MOTHER's NAME": "Yeshoda",

然后https://jsonlint.com对此感到满意。

我猜想\如果需要的话就需要转义。只需将其删除即可，因为'不需要转义。错误文本“ invalid character ':' after array element有点误导，因为它不是引起问题的:。

Answer 2

使用一个非常简单的示例，我已使用peer chaincode invoke命令将一个字符串化的JSON对象传递给chaincode函数，如下所示：

peer chaincode invoke -o localhost:7050 -C mychannel -n pmc -c '{"Args":["initLedger","{\"property1\":\"one\",\"property2\":\"two\"}"]}'

Chaincode参数错误：数组元素后的无效字符“：”
