最近做的一个功能。后台返回了excel文件流，我调用Blob对象生成blob链接进行下载。但是遇到一个很奇怪的问题，在uni-app里提示我Can't find variable: Blob; 但是在PC端H5测试就是完全可行。
请问有人遇到过相同的问题或者类似的问题吗？
代码如下：
uni.request({
url: api.getExcel,
data: {
START_DATE: "2019-08-01 00:00:00",
END_DATE: "2019-08-05 23:00:00"
},
responseType: 'arrayBuffer',
success: res => {
var blob = new Blob([res.data]{type:'application/vnd.openxmlformatsofficedocument.spreadsheetml.sheet; charset=utf-8' })
var downloadElement = document.createElement('a')
var href = window.URL.createObjectURL(blob)
downloadElement.href = href
downloadElement.download = 'result.xlsx'
document.body.appendChild(downloadElement)
downloadElement.click()
document.body.removeChild(downloadElement)
window.URL.revokeObjectURL(href)
}
})
报错信息:
thirdScriptError
