根据policy凭证在web端上传文件

说明

通过接口获取文件直传的policy凭证 (opens new window)或获取新版本直传的policy凭证 (opens new window)后，可以直接在前端使用表单上传方式将文件上传到BIMFACE的对象存储上。

BIMFACE 控制台就是通过这种方式来实现文件上传的，可以F12→network查看请求详情。

以获取到的policy凭证为以下数据示例：

    "message": null,
    "data": {
        "host": "https://bf-prod-srcfile.oss-cn-beijing.aliyuncs.com",
        "policy": "eyJleHBpcmF0aW9uIjoiMjAxOS0wOC0xNVQwNjowOTozMC41NTFaIiwiY29uZGl0aW9ucyI6W1siY29udGVudC1sZW5ndGgtcmFuZ2UiLDAsMTA3Mzc0MTgyNF0seyJzdWNjZXNzX2FjdGlvbl9zdGF0dXMiOiIyMDAifSxbInN0YXJ0cy13aXRoIiwiJGtleSIsIiJdXX0=",

        "expire": 1565849370,

}

通过表单方式上传时，请求的构造方式为：

名称	对应值
请求url	返回体中的host
name	请求体中的name
key	返回体中的objectKey
policy	返回体中的policy
OSSAccessKeyId	返回体中的accessId
callback	返回体中的callbackBody
signature	返回体中的signature
success_action_status	200
file	需要上传文件的binary数据流
