javascript - 无法在json数据中动态传递数据

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) {

});

上面是我的代码。在“FileUId”的 Json 数据中，我动态传递数据。但它不是动态获取数据。我为该值更改了很多方法，但它并没有动态获取。我想动态传递“12345”值。有人可以帮助我吗？

您的字符串连接格式不正确。你应该尝试:

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