如何使用公共密钥合并 2 个 json 文件

Question

我想合并 2 个 JSON 文件

file1.json 看起来像空值

{
  "tests": [{
    "id": 2,
    "title": "Smoke test",
    "value": "",
    "additional_info": "info..."
  }, {
    "id": 41,
    "title": "Debug test",
    "value": "",
    "additional_info": "info..."
  }, {...

file2.json 具有该值

{
  "values": [{
    "id": 2,
    "value": "passed"
  }, {
    "id": 41,
    "value": "passed"
  }, {...

我正在尝试这段代码

import json

with open("file1.json") as fo:
    data1 = json.load(fo)

with open("file2.json") as fo:
    data2 = json.load(fo)

data1.update(data2)

with open("report.json", "w") as fo:
    json.dump(data1, fo)

但它只是连接来自 file1.json 和 file2.json 的 output

最终结果。json 应该是这样的：

{
  "tests": [{
    "id": 2,
    "title": "Smoke test",
    "value": "passed",
    "additional_info": "info..."
  }, {
    "id": 41,
    "title": "Debug test",
    "value": "passed",
    "additional_info": "info..."
  }, {...

Answer 1

那是因为您正在更新根 json object 并获得

{
    "tests": [...],
    "values": [...]
}

虽然您想要的是从单个“值”更新单个“测试”并获得公正

{
    "tests": [...]
}

因此。

尝试遍历两个 json 中的每个 object。
