XUserGetTokenAndSignatureAsync

Asynchronously retrieves xtokens and signatures for web requests.

Syntax

HRESULT XUserGetTokenAndSignatureAsync(  
         XUserHandle user,  
         XUserGetTokenAndSignatureOptions options,  
         const char* method,  
         const char* url,  
         size_t headerCount,  
         const XUserGetTokenAndSignatureHttpHeader* headers,  
         size_t bodySize,  
         const void* bodyBuffer,  
         XAsyncBlock* async  
)  

Parameters

user   _In_
Type: XUserHandle

A handle to the user that the web request is for.

options   _In_
Type: XUserGetTokenAndSignatureOptions

Options for retrieving the user token and signature.

method   _In_z_
Type: char*

The method type for the web request.

url   _In_z_
Type: char*

The URL for the web request.

headerCount   _In_
Type: size_t

The number of headers in the headers parameter.

headers   _In_reads_opt_(headerCount)
Type: XUserGetTokenAndSignatureHttpHeader*

Headers for the web request.

bodySize   _In_
Type: size_t

The size of the buffer in the bodyBuffer parameter.

bodyBuffer   _In_reads_bytes_opt_(bodySize)
Type: void*

A buffer that contains the body of the web request.

async   _Inout_
Type: XAsyncBlock*

An XAsyncBlock for polling the call's status and retrieving call results.

Return value

Type: HRESULT

Returns S_OK if successful; otherwise, returns an error code. For a list of error codes, see Error Codes.

Remarks

To retrieve the result of calling XUserGetTokenAndSignatureAsync, call XUserGetTokenAndSignatureResult.

To retrieve the required buffer size to hold the results of calling XUserGetTokenAndSignatureAsync, call XUserGetTokenAndSignatureResultSize.

The following example demonstrates how to asynchronously retrieve the token and signature of a user.

HRESULT RequestTokenComplete(XAsyncBlock* abResult)
{
    size_t bufferSize;
    RETURN_IF_FAILED(XUserGetTokenAndSignatureResultSize(abResult, &bufferSize));

    std::vector<uint8_t> buffer(bufferSize);
    XUserGetTokenAndSignatureData* data;
    if (SUCCEEDED_LOG(XUserGetTokenAndSignatureResult(abResult, buffer.size(), buffer.data(), &data, nullptr /*bufferUsed*/)))
    {
        appLog.AddLog("Token: %s\n", data->token);
        if (data->signature != nullptr)
        {    
            appLog.AddLog("Signature: %s\n", data->signature);
        }
    }

    return S_OK;
}

HRESULT RequestTokenAsync(
    XTaskQueueHandle queue,
    const char* url,
    bool forceRefresh)
{
    auto asyncBlock = std::make_unique<XAsyncBlock>();
    ZeroMemory(asyncBlock.get(), sizeof(*asyncBlock));
    asyncBlock->queue = queue;
    asyncBlock->context = this;
    asyncBlock->callback = [](XAsyncBlock* ab)
    {
        LOG_IF_FAILED(static_cast<User*>(ab->context)->RequestTokenComplete(ab));
        delete ab;
    };


    XUserGetTokenAndSignatureOptions options = XUserGetTokenAndSignatureOptions::None;

    if (forceRefresh)
    {
        WI_SET_FLAG(options, XUserGetTokenAndSignatureOptions::ForceRefresh);
    }

    static const XUserGetTokenAndSignatureHttpHeader headers[] =
    {
        { "Accept", "application/json"},
        { "Why", "Because"},
    };

    if (SUCCEEDED_LOG(XUserGetTokenAndSignatureAsync(
        _handle.get(),
        options,
        "GET",
        url,
        ARRAYSIZE(headers),
        headers,
        0,
        nullptr,
        asyncBlock.get())))
    {
        // The call succeeded, so release the std::unique_ptr ownership of XAsyncBlock* since the callback will take over ownership.
        // If the call fails, the std::unique_ptr will keep ownership and delete the XAsyncBlock*
        asyncBlock.release();
    }

    return S_OK;
}
