Dart基本认证不工作（dart：io）（更新为工作代码） [英] Dart basic auth not working (dart:io) (UPDATED to working code)

问题描述

我正在使用Harvest API，一个非常标准的网络服务API，我的curl请求正常工作，而我的Dart HttpClient请求不是。这里是我的curl请求（当然是伪装的敏感信息）：

I'm working with the Harvest API, a pretty standard web service API, and my curl requests are working just fine while my Dart HttpClient requests are not. Here is my curl request (with sensitive information disguised, of course):

curl -H "Content-Type: application/json" \
  -H "Accept: application/json" \
  -u "[e-mail]:password" \
  https://my_domain.harvestapp.com/account/who_am_i

UPDATE ---以下代码现在可以正常工作： p>

UPDATE --- The following code now works:

HttpClient client = new HttpClient();
client.addCredentials(
  Uri.parse('https://my_domain.harvestapp.com/account/who_am_i'),
  'realm',
  new HttpClientBasicCredentials('[e-mail]', 'password')
);
client.getUrl(Uri.parse('https://my_domain.harvestapp.com/account/who_am_i'))
  .then((HttpClientRequest req) {
    req.headers
      ..add(HttpHeaders.ACCEPT, 'application/json')
      ..add(HttpHeaders.CONTENT_TYPE, 'application/json');

    return req.close();
  })
  .then((HttpClientResponse res) {
    print(res);
    client.close();
  });
}

显然，我想做的不仅仅是简单的 print 响应，但无论如何， res 对象最终为 null 意味着请求在某些方面失败。有没有什么似乎是错误或失败？

Obviously I would like to do more than simply print the response, but no matter what, the res object ends up being null, which means that the request is failing in some respect. Does anything seem awry or amiss? I'm at a loss for now.

推荐答案

总结原始代码段的变化：

To summarize the changes from the original code snippet:

• 在调用之前调用 HttpClient.addCredentials HttpClient.getUrl c> c $>
  
• 
  
• 在 .then（（HttpClientRequest）） ）


• 确保 addCredentials 和 getUrl 匹配。

• Call HttpClient.addCredentials before calling HttpClient.getUrl
• In the .then((HttpClientRequest)) part, make sure to return req.close()
• Make sure the URLs in addCredentials and getUrl match.
