我正在尝试使用 Google 的日历 API 制作应用程序。我按照这里的指示。我可以请求获取授权码，但我似乎无法形成有效的请求来获取访问令牌。我不断得到回应{"error" : "invalid_request"}。这是我正在发出的 POST 请求：

POST /o/oauth2/token HTTP/1.1
Host: accounts.google.com
Content-Type: application/x-www-form-urlencoded

code=4/vxQqw9JMYEnXvI8A_93OV7kBSg6h.8r2yJUkMc18dshQV0ieZDAraZNwsbwI&
client_id=[my client id]&
client_secret=[my client secret]&
redirect_uri=http://localhost:8080/auth&
grant_type=authorization_code

下面是通过 curl 调用 url 的输出。我的实际应用程序是用 Node.js 编写的，但我从 curl 获得的响应与通过应用程序所做的响应相同。我四处搜索并看到有类似问题的人，但仍然无法弄清楚我做错了什么。

curl -v -k --header "Content-Type: application/x-www-form-urlencoded" --data-urlencode "code=4/vxQqw9JMYEnXvI8A_93OV7kBSg6h.8r2yJUkMc18dshQV0ieZDAraZNwsbwI&client_id=[my client id]&client_secret=[my client secret]&redirect_uri=http://localhost:8080/auth&grant_type=authorization_code" https://accounts.google.com/o/oauth2/token

请求正文应该是这样的单行：

code=4/vxQqw9JMYEnXvI8A_93OV7kBSg6h.8r2yJUkMc18dshQV0ieZDAraZNwsbwI&client_id=[my client id]&
client_secret=[my client secret]&redirect_uri=http://localhost:8080/auth&grant_type=authorization_code

您没有对您的发布请求进行 URL 编码。我可以通过

 redirect_uri=http://localhost:8080/auth

冒号和斜杠没有 %99。我对 wget 有同样的问题。我以为它会为我进行 URL 编码，但它不会。此外，在您的自定义 POST 中，您不能在 & 号和下一个表单 post 值之间添加换行符。它必须全部在一条线上。这也是我使用 wget 的问题。
