富源语音转写是异步任务的方式展开，一个是创建任务，一个是获得任务结果。但在访问这两个接口前需要获得授权 `access_token` ，所以共有三个接口。
#
## 1、获得授权access_token
访问这个接口需要提供`appid`和`secret`，这两者需要到富源平台注册应用，然后在应用的右侧获得。
这个`access_token`的有效时间为两个小时，请注意管理避免过期。
#
~~~[api:notDebug]
get:/v1/token
*appid=a44r4aMbO7BZ1NoW#申请的appid
*secret=a4474wRq9BwujRV7hM4SGH0QMyrEJF5J#申请的appsecret
*grant_type=client_credential#类型
<<<
success
{
"accessToken": "a447bdDAUeKORvmt",
"expires": 7200
}
<<<
403
{
"status": 403,
"error": "SecretIsInvalid",
"message": "无效的 secret"
}
~~~
#
##### C#访问示例代码：
~~~CSharp
var client = new RestClient("http://gateway.api.yun2win.com/v1/token?grant_type=client_credential&appid=a44r4aMbO7BZ1NoW&secret=a4474wRq9BwujRV7hM4SGH0QMyrEJF5J");
client.Timeout = -1;
var request = new RestRequest(Method.GET);
request.AlwaysMultipartFormData = true;
IRestResponse response = client.Execute(request);
Console.WriteLine(response.Content);
~~~
#
##### Java访问示例代码：
~~~ java
OkHttpClient client = new OkHttpClient().newBuilder().build();
Request request = new Request.Builder()
.url("http://gateway.api.yun2win.com/v1/token?grant_type=client_credential&appid=a44r4aMbO7BZ1NoW&secret=a4474wRq9BwujRV7hM4SGH0QMyrEJF5J")
.method("GET", null)
.build();
Response response = client.newCall(request).execute();
~~~
#
#### Nodejs访问示例代码：
~~~javascript
var unirest = require('unirest');
var req = unirest('GET', 'http://gateway.api.yun2win.com/v1/token?grant_type=client_credential&appid=a44r4aMbO7BZ1NoW&secret=a4474wRq9BwujRV7hM4SGH0QMyrEJF5J')
.end(function (res) {
if (res.error) throw new Error(res.error);
console.log(res.raw_body);
});
~~~
#
## 2、创建语音转写任务
上传已录制好的音频（暂只支持mp3，不能超过10M），生成语音转写任务。任务创建成功，自动会加入转写队列。
#
~~~[api:notDebug]
post:/api/lasr/long/create
*file:aduio=c:/a.mp3#已录制好的音频
<<<
success
{
"taskId": "a45D16UhKJ4xeSSO",

"status": "处理中"
}
<<<

错误一:
{
"status": 401,
"error": "AccessTokenNoExist",
"message": "必须有 accessToken"
}
错误二:
{
"status": 401,
"error": "AccessTokenIsInvalid",
"message": "无效的 accessToken"
}
错误三:
{
"status": 401,
"error": "AccessTokenHasExpired",
"message": "accessToken 已过期"
}
<<<

错误一:

}
错误二:

"error": "SecretHasDisabled",
"message": "secret 已被禁用"
}
错误三:
{
"status": 403,
"error": "SecretError",
"message": "secret 状态异常"
}
错误四:
{
"status": 403,
"error": "LimitExceeded",
"message": "已超出用量限制"
}
<<<
500
{
"error":"Params_Audio_Missing",
"message:"请补充语音文件audio栏位（mp3)"
}
{
"error":"Audio_Len_Too_Short",
"message:"音频文件太小，长度不能少于1秒"
}
~~~
#
##### C#访问示例代码：
~~~CSharp
var client = new RestClient("http://gateway.api.yun2win.com/api/lasr/long/create");
client.Timeout = -1;
var request = new RestRequest(Method.POST);
request.AddHeader("Authorization", "Bearer a447bdDAUeKORvmt"); // 这里的a447bdDAUeKORvmt就是接口1取得的access_token
request.AddFile("audio", "/Users/test/Desktop/zv1qh-yfbgq.mp3");
IRestResponse response = client.Execute(request);
Console.WriteLine(response.Content);
~~~
#
##### Java访问示例代码：
~~~ java
OkHttpClient client = new OkHttpClient().newBuilder()
.build();
MediaType mediaType = MediaType.parse("text/plain");
RequestBody body = new MultipartBody.Builder().setType(MultipartBody.FORM)
.addFormDataPart("audio","zv1qh-yfbgq.mp3",
RequestBody.create(MediaType.parse("application/octet-stream"),
new File("/Users/test/Desktop/zv1qh-yfbgq.mp3")))
.build();
Request request = new Request.Builder()
.url("http://gateway.api.yun2win.com/api/lasr/long/create")
.method("POST", body)
.addHeader("Authorization", "Bearer a447bdDAUeKORvmt") // 这里的a447bdDAUeKORvmt就是接口1取得的access_token
.build();
Response response = client.newCall(request).execute();
~~~
#
#### Nodejs访问示例代码
~~~javascript
var unirest = require('unirest');
var req = unirest('POST', 'http://gateway.api.yun2win.com/api/lasr/long/create')
.headers({
'Authorization': 'Bearer a447bdDAUeKORvmt' // 这里的a447bdDAUeKORvmt就是接口1取得的access_token
})
.attach('file', '/Users/test/Desktop/zv1qh-yfbgq.mp3')
.end(function (res) {
if (res.error) throw new Error(res.error);
console.log(res.raw_body);
});
~~~
#
## 3、获得语音转写任务的结果
从接口获得了`taskId`，要获得转写结果需要访问下面接口，建议可以不定期请求，请求间隔时间建议请参考最佳实践。
注意taskId是直接写在访问接口地址中，而不是写在query里。
#
~~~[api:notDebug]
get:/api/lasr/long/:taskId/result
*taskId=a45D16UhKJ4xeSSO#任务Id
<<<
success
{
"status": "已完成",
"result": [
{
"begin": "780", // 此段的开始时间，单位毫秒
"end": "2770", // 此段的结束时间，单位毫秒
"text": "这是做一个测试。" // 此段识别的文字
}
]
}
{
"status": "处理中"
}
<<<

{
"status": 401,
"error": "AccessTokenNoExist",
"message": "必须有 accessToken"
}
错误二:

"message": "无效的 accessToken"
