Question

var updFileId = "12345";

$scope.compGridJson = {
  "peers": ["localhost:7051", "localhost:8051"],
  "fcn": "move",
  "args": ["compGridDetails", "{" +
    "\"FromParty\":\"Valuelabs\",\"CreatedState\":\"24/08/2017\",\"FileUId\":\"+updFileId+\",\"Status\":\"ValueLabs Change Request\"}"
  ]
}
$http({
  method: "POST",
  url: "http://localhost:4000/channels/mychannel/chaincodes/changedneww727",
  data: $scope.compGridJson,
  headers: {
    'Authorization': 'Bearer token',
    'Content-Type': 'application/json'
  }
}).success(function(data, status, headers, config) {

}).error(function(data, status, headers, config) {

});

以上是我的代码。在“FileUId”的Json数据中，我正在动态传递数据。但它没有动态获取数据。我为这个价值改变了很多方法，但它不是动态的。我想动态传递“12345”值。可以帮助我。

字符串连接格式不正确。你应该试试：

$scope.compGridJson = {
  "peers": ["localhost:7051", "localhost:8051"],
  "fcn": "move",
  "args": ["compGridDetails", "{" +
    "\"FromParty\":\"Valuelabs\",\"CreatedState\":\"24/08/2017\",\"FileUId\":\""+updFileId+"\",\"Status\":\"ValueLabs Change Request\"}"
  ]
}

您应该使用json.stringify()

$scope.compGridJson = {
        "peers": ["localhost:7051", "localhost:8051"],
        "fcn": "move",
        "args": ["compGridDetails",  JSON.stringify({
                                        FromParty : "Valuelabs",
                                        CreatedState: "24/08/2017",
                                        FileUId : updFileId,
                                        Status : "ValueLabs Change Request"
        })]
      }

无法在json数据中动态传递数据
