相关疑难解决方法(0)

好的,我可以使用OrderedDict了json.dump.也就是说,OrderedDict可以用作JSON的输入.

但它可以用作输出吗？如果是这样的话？在我的情况下,我想load进入OrderedDict,这样我就可以保持文件中键的顺序.

如果没有,是否有某种解决方法？

我正在尝试更新现有的Json文件,但由于某种原因,请求的值没有被更改,但是整个值集(带有新值)被附加到原始文件

jsonFile = open("replayScript.json", "r+")
data = json.load(jsonFile)


tmp = data["location"]
data["location"] = "NewPath"

jsonFile.write(json.dumps(data))

结果是:必需:

{
   "location": "NewPath",
   "Id": "0",
   "resultDir": "",
   "resultFile": "",
   "mode": "replay",
   "className":  "",
   "method":  "METHOD"
}

实际:

{
"location": "/home/karim/storm/project/storm/devqa/default.xml",
"Id": "0",
"resultDir": "",
"resultFile": "",
"mode": "replay",
"className":  "",
"method":  "METHOD"
}
{
    "resultDir": "",
    "location": "pathaaaaaaaaaaaaaaaaaaaaaaaaa",
    "method": "METHOD",
    "className": "",
    "mode": "replay",
    "Id": "0",
    "resultFile": ""
}
