Question

这将返回错误代码401或500。在我出错的地方，有人可以帮助我吗？

http_client client(L"https://oxford-speech.cloudapp.net/token/issueToken/");    
uri_builder query;
query.append_query(L"grant_type", L"client_credentials");       
query.append_query(L"client_id", L"test-app");
query.append_query(L"client_secret", L"<client secret goes here>");
query.append_query(L"scope", L"https://speech.platform.bing.com");
query.append_query(L"content_type", L"application/x-www-form-urlencoded");

http_request msg(methods::POST);
msg.headers().set_content_type(L"application/x-www-form-urlencoded");
msg.set_request_uri(query.to_string());

std::wstring str = msg.to_string();
return client.request(msg);

谢谢大家。我把代码更改为以下，我得到了令牌！

pplx::task<void> getAccessToken()
{
istream bodyStream;
http_client client(L"https://api.cognitive.microsoft.com/sts/v1.0/issueToken");
http_request req(methods::POST);
req.headers().add(L"Ocp-Apim-Subscription-Key", L"YOUR_KEY");

return client.request(req)

.then([](http_response response)
{
    if (response.status_code() != status_codes::OK)
    {
        return pplx::task_from_result();
    }
    istream bodyStream = response.body();
    container_buffer<std::string> inStringBuffer;       
    return bodyStream.read_line(inStringBuffer)

.then([inStringBuffer](size_t bytesRead)
{
    const std::string &text = inStringBuffer.collection();
    std::cout << text;
});

});
};

这是我上次尝试的请求的通用JSON表示（2016年9月）。你的要求看起来很不一样。摘自Woundify settings file
