How do i add a CORS rule to the Azure Storage Emul

问题:

To use the Azure Storage (Emulator) Table Service, i need to add a CORS rule for my TypeScript Browser App.

I want to add that rule manually using the REST interface (from Postman, not the Browser with the Same Origin Policy). The documentation does not give the correct URL for the Emulator (https://docs.microsoft.com/en-us/rest/api/storageservices/fileservices/set-table-service-properties). For DML commands it is like in my request (https://docs.microsoft.com/en-us/rest/api/storageservices/fileservices/insert-entity).

The request is:

PUT /devstoreaccount1/?restype=service&comp=properties HTTP/1.1
Host: 127.0.0.1:10002
x-ms-version: 2013-08-15
Content-Type: application/xml
Cache-Control: no-cache
Postman-Token: 280f880b-d6df-bb1d-bc12-eca411e18310

<StorageServiceProperties>
    <Cors>
        <CorsRule>
            <AllowedOrigins>http://localhost:3030</AllowedOrigins>
            <AllowedMethods>GET,PUT,POST</AllowedMethods>
            <MaxAgeInSeconds>500</MaxAgeInSeconds>
            <ExposedHeaders>x-ms-meta-data*,x-ms-meta-target*,x-ms-meta-abc</ExposedHeaders>
            <AllowedHeaders>x-ms-meta-*</AllowedHeaders>
        </CorsRule>
    </Cors>
</StorageServiceProperties>

The result is:

<?xml version="1.0" encoding="utf-8"?>
<m:error xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata">
    <m:code>ResourceNotFound</m:code>
    <m:message xml:lang="en-US">The specified resource does not exist.

Time:2017-01-15T09:13:51.7500394Z</m:message>
</m:error>

What is the correct URL or what am i doing wrong?

回答1:

If you download the Microsoft Azure Storage Explorer, you can set it up by right clicking on "Blob Containers" under your account.

Here is a Powershell script to add a CORS rule to the Azure Storage Emulator. It is not the answer to this question but a solution for my problem:

$ErrorActionPreference = "Stop";

# config

$AccountName='devstoreaccount1'
$AccountKey='Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw=='

# derived config

$BlobEndpoint="http://127.0.0.1:10000/$($AccountName)"
$QueueEndpoint="http://127.0.0.1:10001/$($AccountName)"
$TableEndpoint="http://127.0.0.1:10002/$($AccountName)"

$ConnectionString = "" +
    "DefaultEndpointsProtocol=http;" + 
    "BlobEndpoint=$($BlobEndpoint);" +
    "QueueEndpoint=$($QueueEndpoint);" +
    "TableEndpoint=$($TableEndpoint);" +
    "AccountName=$($AccountName);" +
    "AccountKey=$($AccountKey)"

# authentication

$Context = New-AzureStorageContext `
    -ConnectionString $ConnectionString

# cors rules
$CorsRules = (@{
    AllowedHeaders=@("*");
    AllowedOrigins=@("*");
    ExposedHeaders=@("Content-Length");
    MaxAgeInSeconds=60*60*24;
    AllowedMethods=@("Get", "Post")
})

Set-AzureStorageCORSRule `
    -ServiceType Table `
    -Context $Context `
    -CorsRules $CorsRules

# check
Get-AzureStorageCORSRule `
    -ServiceType Table `
    -Context $Context
