首先需要注册一个账号并申请成为个人开发者获取APP ID和密匙
百度翻译开放平台进入该网站注册即可
完成之后即可点击开通翻译其他服务
选择通用翻译并选择标准版,然后填入信息即可,服务器地址百度搜索IP地址,然后填写搜到的本机地址就可以了。
百度翻译的API如下,复制粘贴走即可,官网的有个异常没处理,会报错,我这个是修改以后的。
我这个是Java版本的,其他语言可去官网下载

APPID和密匙可在全局变量声明
private static final String APP_ID = "**********";//自己的是啥就输入啥private static final String SECURITY_KEY = "************";
下面就是进行调用,得到的transResult就是翻译结果,目标语言的对应代码也在下面的表中。
但是得到的数据要进行一些处理,代码我就不放上来了,解决思路提醒一下,可以用正则表达式来匹配翻译结果,翻译成英文是没什么问题的,使用正则表达式匹配之后就是翻译后的文本,但是翻译成一些语言时会返回Unicode码,自己写个方法解码就可以了。
TransApi api = new TransApi(APP_ID, SECURITY_KEY);String transResult = api.getTransResult(需翻译的文本字符串, "auto", 目标语言);
如果在运行时出现了错误,根据下面的表所返回的错误码进行修改
免费版本一般容易出现的错误是54003访问频率受限,58000客户端IP非法,和90107认证未通过或未生效。
对于访问频率受限的错误,可通过不多次调用来解决,比如你要翻译一个文本的多个单词,不要一次传一个,一次性全部传入并返回结果即可。
对于58000客户端非法这个错误,去检查下你的客户端地址有没有填错,直接百度搜索IP地址,就可以看到自己的IP,检查下百度翻译开发者信息里面,所使用的服务的IP地址是否和自己IP地址一致。
90107认证未通过或者未生效,去百度翻译官网看看自己开通服务信息有没有填错。
