Question

我正在使用 rest api 获取数据。我想在响应输出“数据”部分用 null（或其他数字）替换所有 0 值。

headers = {
    "cookie": "JSESSIONID=....",
    "Authorization": "Basic ...",
    "Content-Type": "application/json"
}

response = requests.request("POST", url, json=payload, headers=headers, params=querystring, verify=False).text

响应输出：

{
    "status": {
        "total": 1,
        "matched": 1,
        "processed": 1,
        "completed": true,
        "aborted": false,
        "hasErrors": false,
    },
    "result": [

                        3383,
                    ],
                }
            ],
        },
    ],
}

我需要用“数据”中的空值替换所有 0 值：[] 值。我该怎么做？

此解决方案仅适用于具有所需结构的数据。

data = {} # omitted

for v in data["result"]:
    for v in v["syn_raidLdev_transferRate"]:
        dt = v["data"]
        for i, v in enumerate(dt):
            if v == 0:
                dt[i] = None

print(data)

此外，还有保存结果数据的方法

import json 

     
with open("result.json", "w") as outfile: 
    json.dump(data, outfile)

python更改0值
