使用 golang 记录器（最好是 logrus）在文件中记录 JSON object

Question

如何使用 Golang 中的 logger(logrus) 将 Json 行（ Json 对象由行分隔）写入文件。

代码

f, err := os.OpenFile("data.json", os.O_RDWR|os.O_CREATE|os.O_APPEND, 0666)
    if err != nil {
        log.Fatalf("error opening file: %v", err)
    }
    defer f.Close()

    log.SetFormatter(&log.JSONFormatter{})
    log.SetOutput(f)
    log.Println("data_point:0,Add:0,Mload:0")

Output in data.json文件收到

{"level":"info","msg":"data_point:0,Add:0,Mload:0","time":"2022-02-05T22:38:51+05:30"}
{"level":"info","msg":"data_point:0,Add:0,Mload:0","time":"2022-02-05T22:38:51+05:30"}

Output 格式应该是

{"data_point":0,"Add":0,"Mload":0}
{"data_point":0,"Add":0,"Mload":0}
{"data_point":0,"Add":0,"Mload":0}
