今天在爬取文章的時(shí)候眉反，在將數(shù)據(jù)插入mysql數(shù)據(jù)庫的時(shí)候笆呆，出現(xiàn)了Incorrect string value: '\xF0\x9F\x98\xAD",...' for column 'commentContent' at row 1 這個(gè)錯(cuò)誤呵曹，Google了下發(fā)現(xiàn)原來是因?yàn)閿?shù)據(jù)庫編碼問題導(dǎo)致的脏款，原因在于我們的評(píng)論數(shù)據(jù)中存在emoj表情酱讶，而這些表情是按照四個(gè)字節(jié)一個(gè)單位進(jìn)行編碼的退盯，而我們通常使用的utf-8編碼在mysql數(shù)據(jù)庫中默認(rèn)是按照3個(gè)字節(jié)一個(gè)單位進(jìn)行編碼的，正是這個(gè)原因?qū)е聦?shù)據(jù)存入mysql數(shù)據(jù)庫的時(shí)候出現(xiàn)錯(cuò)誤浴麻，那么這個(gè)問題我們應(yīng)該怎么解決呢得问？
分為下面三個(gè)步驟來解決：
(1)修改mysql數(shù)據(jù)庫的編碼為uft8mb4
(2)修改數(shù)據(jù)表的編碼為utf8mb4
(3)修改連接數(shù)據(jù)庫的連接代碼
其中：
(1)修改mysql數(shù)據(jù)庫的編碼為uft8mb4
ALTER SCHEMA ak47_cms DEFAULT CHARACTER SET utf8mb4 DEFAULT COLLATE utf8mb4_general_ci ;
修改方法：
參看：http://blog.csdn.net/poice00/article/details/52129351
(2)：修改數(shù)據(jù)表的編碼為utf8mb4
執(zhí)行命令：ALTER TABLE TABLE_NAME CONVERT TO CHARACTER SET utf8mb4;
(3)：修改連接數(shù)據(jù)庫的連接代碼
