node.js https POST 和 body-attributes - 如何？

Question

我正在尝试使用我的 node.js 服务器获取令牌。

当有人调用我的服务器的 REST-API 时，将执行下面的代码（在此调用的处理过程中，服务器自己进行了多次调用）。

以下配置适用于 POSTMAN：

URL: https://login.windows.net/MyCompanyTenant.onmicrosoft.com/oauth2/token

Header:

• Cache-Control: no-cache
• Content-Type: application/x-www-form-urlencoded

Body:

• client_id: YourClientIdFromAzureAd
• 资源：https://myCompanyTenant.crm.dynamics.com
• 用户名：yourServiceUser@myCompanyTenant.onmicrosoft.com
• 密码：您的服务用户密码
• grant_type: 密码
• client_secret: YourClientSecretFromAzureAd

现在我尝试构建此请求的失败代码：

function retrieveAuthToken() {
    var deferred = q.defer();   

    var bodyDataString = querystring.stringify({
        grant_type: "password",
        client_id:  someClientId, 
        resource: someUrl,
        username: someUsername,
        password: someUsernamePassword,        
        client_secret: someString
   });
   //I also tried replacing thie bodyDataString by the bodyString from the working request provided by Fiddler

    var options = {
        host: 'login.windows.net',
        path: '/someTenant/oauth2/token',
        method: 'POST',
        headers: {
            "Content-Type": "application/x-www-form-urlencoded",
            "Cache-Control": "no-cache"
        }
    };  

    var request = https.request(options, function(response){
        var body = '';
        response.on('data', function(d) {
            body += d;
        });
        response.on('end', function() {
            var parsed = JSON.parse(body); //todo: try/catch
            rdeferred.resolve(parsed.access_token);
        });               
    });

    request.on('error', function(e) {
        console.log(e.message);
        deferred.reject();
    });

   request.write(bodyDataString ); 
   return deferred.promise;

我没有看到任何错误，我的服务器一直在等待...

您缺少 request.end() 来完成请求。或者作为快捷方式，您可以将单个 request.write(bodyDataString) 更改为 request.end(bodyDataString).
