获取AccessToken

获取AccessToken

接口说明

• 为每个第三方访问者发放AppId和AppSecret
• 访问者使用AppId和AppSecret通过本接口获取AccessToken

请求URL

/openapi/v2/common/getAccessToken?appid=xxxx&timestamp=xxxx&nonce=xxxx&sign=xxxx

• 接口统一为 UTF-8 编码；
• 接口支持 http 和 https；
• 请求方式为GET。

请求参数

appid & appsecret

• 服务器端生成appid&appsecret对，提供给访问方

timestamp

• 1970-01-01以来的秒数
• 和服务器间隔超过10分钟无效

nonce

• 随机值字符串

加签方式

sign=MD5(appsecret + appid + timeStamp + nonce + appsecret)

返回结果

例子

• appid: “Jx3wQMD1”
• timestamp: “1676874831”
• nonce:”cbQSLn4Ipaa9dUBrMErWAlnGFO3fewY”
• app_secret：”d68397c4fb671bc024e24e1964b067cc35388818”

GET

• sign:”5aef2812c4aa99ac901d66a5edf26e15”

响应

返回值（code）
