因为讯飞官方提供的sdk没有Java的,所以我使用的是WebApi。其中有些注意事项官网有写出，可自行查看。
下面是具体的接入过程：
下载这个demo 然后把里面的三个文件复制到项目里
主要用到的是FileUtil.java这个文件

这是我修改过的，有这么几个地方要修改
123这三个属性的值要从控制台获取
5：全维度评测，这个需要开通，和免费数量是区分开的，要单独付费
还有一个就是文本这块（我的项目是前端传值，所以我这里把他原来的注掉了），这个地方需要注意的就是：文本内容要正规，标点符号等都要有，要不然影响评测质量
4：评测级别：这个建议最好用“simple”,如果用"entity"的话返回内容太多了，前端不好解析
这些弄好之后直接调用就可以实现评测，
比较麻烦的地方在语评测的音频处理
官方给的音频是wav格式的，要转换，要不然没法评测
ffempg的使用可以参考这篇文章
ffempg安装使用
命令用官方的就行
ffmpeg -y -i test.wav -acodec pcm_s16le -f s16le -ac 1 -ar 16000 test.pcm
转换好之后就可以用postman测试一下是否调用成功
成功了返回的是一长串结果json
额，公司的全维度评测今天到期了，评测结果我就用官方给的吧
这个是失败的情况，会返回错误编码，这个在官网可以查到对应的原因，方便排错
如果成功了是这样
{"data":{"read_word":{"lan":"en","type":"study","version":"6.5.0.1011","rec_paper":{"read_word":{"except_info":"28680","is_rejected":"false","total_score":"64.725080","sentence":[{"beg_pos":"0","content":"apple","end_pos":"129","word":{"beg_pos":"79","content":"apple","end_pos":"129","total_score":"94.963020"}},{"beg_pos":"129","content":"banana","end_pos":"163","word":{"beg_pos":"163","content":"banana","end_pos":"163","total_score":"0.000000"}},{"beg_pos":"163","content":"orange","end_pos":"226","word":{"beg_pos":"163","content":"orange","end_pos":"226","total_score":"99.212200"}},{"content":"banana","end_pos":"359","word":{"beg_pos":"265","content":"banana","end_pos":"318"},"beg_pos":"226"}],"beg_pos":"0","content":"apple banana orange","end_pos":"359"}}}},"code":"0","desc":"success","sid":"wse00000001@ll36940e324c59000100"}
返回的就是很长的json串（评测级别是"entity"，所以会有很多），中间会有几个关键的参数
这就是评测返回的结果对应的分数字段
到这里就结束了，有不明白的可以留言。感觉写的很清楚了，哈哈！
