尽管字符串是有效的 UTF8,但字节序列无效

Invalid byte sequence allthough string is a valid UTF8

我正在尝试将 txt 写入 postgres 批量导入器。该代码当前崩溃,因为应该插入到 postgres 的字符串不是有效的 UTF8:pq: invalid byte sequence for encoding UTF8: 0x00

在我的代码中,我正在检查字符串是否为有效的 UTF8。

我错过了什么?

代码:

for {
        line, more := <-lineChannel

        splitLine := strings.SplitN(line, ":", 2)

        if len(splitLine) == 2 {
            if utf8.Valid([]byte(splitLine[0])) && utf8.Valid([]byte(splitLine[1])) {
                lineCount++
                _, err = stmt.Exec(splitLine[0], splitLine[1])

                if lineCount%int64(copySize) == 0 {

                    _, err = stmt.Exec()
                    if err != nil {
                        log.Fatal("Failed at stmt.Exec", err)
                    }

                    err = stmt.Close()
                    if err != nil {
                        log.Fatal("Failed at stmt.Close", err)
                    }

                    err = txn.Commit()
                    if err != nil {
                        log.Fatal("failed at txn.Commit", err)
                    }

                    txn, err = db.Begin()
                    if err != nil {
                        log.Fatal("failed at db.Begin", err)
                    }

                    stmt, err = txn.Prepare(pq.CopyIn("pwned", "username", "password"))
                    if err != nil {
                        log.Fatal("failed at txn.Prepare", err)
                    }

                    if lineCount%(int64(copySize)*10) == 0 {
                        log.Printf("Inserted %v lines", lineCount)
                    }
                }

                if err != nil {
                    log.Println("error:", splitLine[0], splitLine[1])
                    log.Fatal(err)
                }
            }

编辑: 出错的行:

行:username@hotmail.whatever:hushpuppieslove

分割线[0] + 分割线[1]: username@hotmail.whatever hushpuppieslove

0x00 是空字符,postgres 不允许在字符串中使用。来自 the docs:

The NULL (0) character is not allowed because text data types cannot store such bytes.

您需要删除空字符。
