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:
