我正在嘗試解析 AWS Lambda 的事件數據，我已將其連接到 SQS，并使用 SQS 發送 JSON 格式。這是我的 AWS Lambda 函數import jsondef lambda_handler(event, context): # print(event) # print(event['Records'][0]) x = event['Records'][0]['body'] print(x) print(type(x))以下是事件數據{ "Records":[ { "messageId":"916f5e95-b2f6-4148-9c62-2ac8e764f06c", "receiptHandle":"AQEBmLuoGWtLtFFgvyCFdSPMJh2HKgHOIPWNUq22EOwCzGT8iILZm97CE6j4J6oR71ZpDr3sgxQcJyVZ+dmmvGl+fFftT9GCJqZYrjMGsR2Q6WsMd8ciI8bTtDXyvsk8ektd7UGfh4gxIZoFp7WUKVRcMEeBkubKd8T4/Io81D0l/AK7MxcEfCj40vWEsex1kkGmMRlBtdSeGyy7fJgUq5CFAYWciiWtbSit8S0Y38xZPmsIFhoxP0egQRoJcW4aUgMi469Gj5+khizetybtgC8vux5NCg/IejxcCueXkQ7LKVF8kfRdqRSUYB6DsOrGgfmZpK4wpXIarByNz0R2p7J88meYpj2IVULv/emXsSYaKG4rXnpbH4J9ijbLWckYLAd7wPDzCYri1ZSTgAz0kchsEw==", "body":"{\n\"name\": \"aniket\",\n\"tag\": \"hello\"\n}", "attributes":{ "ApproximateReceiveCount":"1", "SentTimestamp":"1602046897707", "SenderId":"AIDAR3BXDV4FCWXL56NUU", "ApproximateFirstReceiveTimestamp":"1602046897712" }, "messageAttributes":{ }, "md5OfBody":"98da683a47692b39c1d43bd4fa21ed89", "eventSource":"aws:sqs", "eventSourceARN":"arn:aws:sqs:ap-south-1:126817120010:documentation", "awsRegion":"ap-south-1" } ]} 我正在嘗試訪問數據正文。這就是我得到的"{\n\"name\": \"aniket\",\n\"tag\": \"hello\"\n}"它的類型是字符串。我需要做什么才能將其轉換為正確的 JSON 格式？我還嘗試了以下方法：import jsondef lambda_handler(event, context): data = json.dumps(event['Records'][0]['body']) print(data)這是輸出"{\n\"name\": \"aniket\",\n\"tag\": \"hello\"\n}"但這次的類型是 JSON。預期的格式是{"name": "aniket","tag": "hello"}

你必須使用json.loadsnot json.dumps。
嘗試這個：
import json
event = {
"Records":[
{
"messageId":"916f5e95-b2f6-4148-9c62-2ac8e764f06c",
"receiptHandle":"AQEBmLuoGWtLtFFgvyCFdSPMJh2HKgHOIPWNUq22EOwCzGT8iILZm97CE6j4J6oR71ZpDr3sgxQcJyVZ+dmmvGl+fFftT9GCJqZYrjMGsR2Q6WsMd8ciI8bTtDXyvsk8ektd7UGfh4gxIZoFp7WUKVRcMEeBkubKd8T4/Io81D0l/AK7MxcEfCj40vWEsex1kkGmMRlBtdSeGyy7fJgUq5CFAYWciiWtbSit8S0Y38xZPmsIFhoxP0egQRoJcW4aUgMi469Gj5+khizetybtgC8vux5NCg/IejxcCueXkQ7LKVF8kfRdqRSUYB6DsOrGgfmZpK4wpXIarByNz0R2p7J88meYpj2IVULv/emXsSYaKG4rXnpbH4J9ijbLWckYLAd7wPDzCYri1ZSTgAz0kchsEw==",
"body":"{\n\"name\": \"aniket\",\n\"tag\": \"hello\"\n}",
"attributes":{
"ApproximateReceiveCount":"1",
"SentTimestamp":"1602046897707",
"SenderId":"AIDAR3BXDV4FCWXL56NUU",
"ApproximateFirstReceiveTimestamp":"1602046897712"
},
"messageAttributes":{
},
"md5OfBody":"98da683a47692b39c1d43bd4fa21ed89",
"eventSource":"aws:sqs",
"eventSourceARN":"arn:aws:sqs:ap-south-1:126817120010:documentation",
"awsRegion":"ap-south-1"
}
]
}
parsed = json.loads(event['Records'][0]['body'])
print(json.dumps(parsed, indent=4, sort_keys=True))
輸出：
{
"name": "aniket",
"tag": "hello"
}

嘗試使用 json.loads(string) 反序列化 json。
另外，我認為您不需要指定索引 [0]，因為“body”是一個對象而不是數組。
