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) { 

}); 

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

字符串连接不正确。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\"}" 
    ] 
}

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" 
     })] 
     }
