[英]How to parse a json with escaped string into smaller json with node js or python
I'm using AWS step functions and want to parse the following json with a node js or python lambda function (the language is irrelevant, I just need the results): I'm using AWS step functions and want to parse the following json with a node js or python lambda function (the language is irrelevant, I just need the results):
{
"stage": "dev",
"server": {
"instanceId": "i-xxxx",
"status": "running"
},
"message": [
{
"MessageId": "xxx",
"ReceiptHandle": "xxx",
"MD5OfBody": "xxx",
"Body": "{\n \"stage\": \"DEV\",\n \"id\": \"5\",\n \"results\": \"D:\\\\Temp\\\\results\"\n}",
"Attributes": {
"SenderId": "xxxx",
"ApproximateFirstReceiveTimestamp": "xxx",
"ApproximateReceiveCount": "1",
"SentTimestamp": "xxx",
"SequenceNumber": "xxx",
"MessageDeduplicationId": "20",
"MessageGroupId": "20"
}
}
]
}
I just need the "message.Body"-Part.我只需要“message.Body”部分。 I'd like to split this into three vars for further actions:
我想将其拆分为三个变量以进行进一步操作:
{
"stage":"DEV",
"id":"5",
"results":"D:\\Temp\\results"
}
Could someone help me with this?有人可以帮我解决这个问题吗? I just spent the last hour with JSON.stringify, parse, unescape and so on, unfortunately without success:(
我刚刚花了最后一个小时 JSON.stringify, parse, unescape 等等,不幸的是没有成功:(
Thank you in advance!先感谢您!
Does this work?这行得通吗?
import json
jsondata = {
"stage": "dev",
"server": {
"instanceId": "i-xxxx",
"status": "running"
},
"message": [
{
"MessageId": "xxx",
"ReceiptHandle": "xxx",
"MD5OfBody": "xxx",
"Body": "{\n \"stage\": \"DEV\",\n \"id\": \"5\",\n \"results\": \"D:\\\\Temp\\\\results\"\n}",
"Attributes": {
"SenderId": "xxxx",
"ApproximateFirstReceiveTimestamp": "xxx",
"ApproximateReceiveCount": "1",
"SentTimestamp": "xxx",
"SequenceNumber": "xxx",
"MessageDeduplicationId": "20",
"MessageGroupId": "20"
}
}
]
}
jsonbody = json.loads(jsondata.get('message')[0].get('Body'))
print(jsonbody)
# {'stage': 'DEV', 'id': '5', 'results': 'D:\\Temp\\results'}
Here is my way of implementing it in Python,这是我在 Python 中实现它的方式,
import json
dic = {
"stage": "dev",
"server": {
"instanceId": "i-xxxx",
"status": "running"
},
"message": [
{
"MessageId": "xxx",
"ReceiptHandle": "xxx",
"MD5OfBody": "xxx",
"Body": "{\n \"stage\": \"DEV\",\n \"id\": \"5\",\n \"results\": \"D:\\\\Temp\\\\results\"\n}",
"Attributes": {
"SenderId": "xxxx",
"ApproximateFirstReceiveTimestamp": "xxx",
"ApproximateReceiveCount": "1",
"SentTimestamp": "xxx",
"SequenceNumber": "xxx",
"MessageDeduplicationId": "20",
"MessageGroupId": "20"
}
}
]
}
message_body_str = dic['message'][0]['Body']
print(json.dumps(json.loads(message_body_str)))
