Question

我有以下UTF-8字节字符串我试图存储在MySQL表（utf8mb4）中，但是从mysql服务器获取失败。

...
db.Exec("SET NAMES 'utf8mb4'; SET CHARACTER SET utf8mb4;")

var badBytes = []byte{
    34, 48, 34, 32, 47, 62, 66, 117, 121, 32, 105, 116, 32, 110, 111, 119, 32,
    240, 159, 147, 149, 32, 60, 97, 32, 104, 114, 101, 102, 61, 34, 104, 116,
}

fmt.Println("UTF8 Valid", utf8.Valid(badBytes))
fmt.Println()
fmt.Println(string(badBytes))
fmt.Println()

res, err := db.Exec("INSERT INTO demo (body) VALUES (?)", string(badBytes))
if err != nil {
    log.Fatal(err)
}

id, err := res.LastInsertId()
fmt.Println(id, err)

输出低于

UTF8 Valid true

Error 1366: Incorrect string value: '\xF0\x9F\x93\x95 <...' for column 'body' at row 1

MySQL表和连接都是utf8mb4：

CREATE TABLE `demo` (
  `id` int(11) unsigned NOT NULL AUTO_INCREMENT,
  `body` text COLLATE utf8mb4_unicode_ci,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;

Like @Rico said我需要指定排序规则（utf8mb4_unicode_ci），因此go-mysql lib默认为Traceback (most recent call last): File "socket.py", line 1, in <module> import socket File "/home/linuxmint/Desktop/socket.py", line 9, in <module> iphost() File "/home/linuxmint/Desktop/socket.py", line 5, in iphost packed = socket.inet_aton('192.168.1.15','127.0.0.1') AttributeError: module 'socket' has no attribute 'inet_aton'并导致我的4byte unicode符文出现问题（mysql＆＃39; s utf8仅支持最多3字节的unicode）。

utf8
