我们在vue.js应用程序中使用axios来访问Azure功能.现在我们收到这个错误:

No 'Access-Control-Allow-Origin' header is present on the requested resource. 
Origin 'http://localhost:8080' is therefore not allowed access.

我们试图以这种方式在函数中设置响应头:

context.res = {
        body: response.data,
         headers: {   
          'Access-Control-Allow-Credentials': 'true',
          'Access-Control-Allow-Origin': 'http://localhost:8080',
          'Access-Control-Allow-Methods': 'GET',
          'Access-Control-Request-Headers': 'X-Custom-Header'
         }
      }

有没有人遇到过这个错误？

我无法让ifModifiedSince工作.这是我的代码:

func updateDatabase()
{
    let objectRequest = AWSS3GetObjectRequest()
    objectRequest?.key = "wa/wa2016/idahoGmu.tiff"
    objectRequest?.bucket = bucketName

    let dateComponents = NSDateComponents()
    dateComponents.day = 10
    dateComponents.month = 4
    dateComponents.year = 2018
    let date = NSCalendar.current.date(from: dateComponents as DateComponents)

    // TODO This isn't working.  It grabs the file regardless of date.
    objectRequest?.ifModifiedSince = date

    let s3 = AWSS3.default()

    s3.getObject(objectRequest!).continueWith
    {
        (task) -> AnyObject! in if let error = task.error
        {
            print("Error: \(error.localizedDescription)")
        }

        if let result = task.result
        {
            let fileManager = FileManager.default
            let documents …
