opencpu不一致的json序列化

嗨我想使用robfilter使用。作爲默認robfilter反應不是JSON序列化因此我創建了自己的包使用此功能：opencpu不一致的json序列化

detectOutliers <- function(json, windowWidth) { 
    x <- json 
    robfil <- robust.filter(x[[2]], width=windowWidth, outlier="T", online=FALSE) 
    outlierDf <- data.frame(period=x[[1]], totalAmount=x[[2]], isOutlier=robfil$ol) 
    return(outlierDf) 
}

當一個像

args <- fromJSON('{"json":[{"Period":1393632000,"x":453.2003},{"Period":1396310400,"x":742.9013},{"Period":1398902400,"x":52366.3592},{"Period":1401580800,"x":7660.234},{"Period":1404172800,"x":3967.7503},{"Period":1406851200,"x":2620.771},{"Period":1409529600,"x":1927.5348},{"Period":1412121600,"x":2094.795},{"Period":1414800000,"x":1830.223},{"Period":1417392000,"x":2286.1982},{"Period":1420070400,"x":3047.4511},{"Period":1422748800,"x":2001.4622},{"Period":1425168000,"x":1763.6833},{"Period":1427846400,"x":2033.9456},{"Period":1430438400,"x":4568.8964},{"Period":1433116800,"x":2104.0584},{"Period":1435708800,"x":1522.6288},{"Period":1438387200,"x":533.8585},{"Period":1441065600,"x":667.3039}], "windowWidth":11}') 
outliers <- do.call(detectOutliers, args) 
outliers

本地測試它正確地顯示了以下數據幀，其中每行填充

period totalAmount isOutlier 
1 1393632000 453.2003   0 
2 1396310400 742.9013   0 
3 1398902400 52366.3592   1 
4 1401580800 7660.2340   0 
5 1404172800 3967.7503   0 
.....

toJson(outliers)反過來正確串行化該數據幀。

但在opencpu稱爲像

curl http://opencpuURL/ocpu/library/possibly/R/detectOutliers/json -d \ 
'{"json":[{"Period":1393632000,"x":453.2003},{"Period":1396310400,"x":742.9013},{"Period ":1398902400,"x":52366.3592},{"Period":1401580800,"x":7660.234},{"Period":1404172800,"x":3967.7503},{"Period":1406851200,"x":2620.771},{"Period ":1409529600,"x":1927.5348},{"Period":1412121600,"x":2094.795},{"Period":1414800000,"x":1830.223},{"Period":1417392000,"x":2286.1982},{"Period ":1420070400,"x":3047.4511},{"Period":1422748800,"x":2001.4622},{"Period":1425168000,"x":1763.6833},{"Period":1427846400,"x":2033.9456},{"Period ":1430438400,"x":4568.8964},{"Period":1433116800,"x":2104.0584},{"Period":1435708800,"x":1522.6288},{"Period":1438387200,"x":533.8585},{"Period ":1441065600,"x":667.3039}],"windowWidth":11}' \ 
-H "Content-Type: application/json"

後的結果很奇怪。正如你所看到只包含2場

[ 
    { 
    "period": 1393632000, 
    "totalAmount": 453.2003, 
    "isOutlier": 0 
    }, 
    { 
    "period": 1396310400, 
    "totalAmount": 742.9013, 
    "isOutlier": 0 
    }, 
    { 
    "totalAmount": 52366.3592, 
    "isOutlier": 1 
    }, 
....

這裏有什麼問題一定行？

JSON負載中有一些空格。使用類似於

「{\」json \「：[{\」Period \「：2，\」x \「：1}，{\」Period \「：1，\」x \「：1 }，{\「Perio d \」：3，\「x \」：1}] \「windowWidth \」：「3」}「-H」Content-Type：application/json「
