Question

我正在尝试解析以下JSON数据并使用python Function获取URL值。从下面的JSON示例中，我想从Jobs标记下获取URL并将其存储在2个数组中。 1个数组将存储带有颜色标签的URL，其他数组将存储没有颜色标签的URL。一旦两个数组准备就绪，我想返回这两个数组。我是python新手，需要一些帮助。

exports.myMethod2 = functions.https.onCall((data, context) => {
    utilsModule.throwIfNoAuth(context);
    return methodWithTransaction(context, admin);
});

exports.methodWithTransaction = function (context, admin) {
    //this is called only once from outside!
    return rootRef.child("my/data/path").once("value")
        .then(function (indexRef) {
            var usageObj = indexRef.val();
            //update object's state
            usageObj =
                {
                    timestampUtcArray: [1530656089821, 1530656089822],
                    itemsCount: 2,
                    writeTimestamp: 1530656502759
                }
            return usageObj;
        })
        .then(function (usageObj) {
            //her eis the sad part...
            return rootRef.child("my/data/path").transaction(data => {
                //this method always run 25 times and fails.
                //data aways != usageObj though accross the calls usageObj are the same as well data are the same:
                // usageObj =
                //     {
                //         timestampUtcArray: [1530656089821, 1530656089822],
                //         itemsCount: 2,
                //         writeTimestamp: 1530656502759 <-- only timestamp is different
                //     }
                // data =
                //     {
                //         timestampUtcArray: [1530656089821, 1530656089822],
                //         itemsCount: 2,
                //         writeTimestamp: 1530656503421 <-- only timestamp is different
                //     }

                return usageObj;
            }
        })

}

以下是我用于获取作业数据的python代码，但随后无法遍历作业数据以获取所有URL。更改代码一次只能获得1

              ]
            }

我在这里得到第二个URL，但是无法检查此条目是否带有颜色标签

Answer 1

首先，您的JSON格式不正确。您将必须使用JSON formatter来检查其有效性并解决所有问题。

也就是说，您必须使用-p作为字符串读取文件

In [87]: with open('data.json', 'r') as f:
    ...:     data = f.read()
    ...:

然后使用json库将数据加载到dict

In [88]: d = json.loads(data)

然后您可以使用2个列表推导来获取所需的数据

In [90]: no_color = [record['url'] for record in d['jobs'] if 'color' not in record]

In [91]: color = [record['url'] for record in d['jobs'] if 'color' in record]

In [93]: no_color
Out[93]:
['https://tdyt.com/job/CONSOLIDATED/job/yfiyf/',
 'https://ygduey.com/job/CONSOLIDATED/job/Ops-Prod-Jobs/',
 'https://futfu.com/job/CONSOLIDATED/job/TEST-DATA-MGMT/',
 'https://gfutfu.com/job/CONSOLIDATED/job/TESTING-OPS/',
 'https://ytdyt.com/job/CONSOLIDATED/job/Performance_Engineering%20Team/']

In [94]: color
Out[94]: ['https://tduta.com/job/CONSOLIDATED/job/test/']
