您无权执行此操作。无效的访问令牌DialogFlow v2 [英] You are not authorized for this operation. Invalid access token DialogFlow v2

问题描述

我正在尝试使用DialogFlow v2端点，但是由于某种原因我没有得到授权消息，因此我可以使用以下命令生成访问令牌：

I am trying to use DialogFlow v2 endpoint but for some reason I am getting not authorized message, eventhou I am able to generate access token using the following command:

最初，我正在运行此命令来为我的本地计算机授权该服务，以便能够对该服务进行授权： gcloud auth activate-service-account --key-file =< service-account-key-file .json> ，然后通过以下命令获取访问令牌： gcloud auth print-access-token 和此访问令牌，我将其附加在以下代码上：

Initially I am running this to authorize the service for my local machine to be able to authorize to the service: gcloud auth activate-service-account --key-file=<service-account-key-file.json> then I get access token by following command: gcloud auth print-access-token and this access token I am attaching on the following code:

fetch(configs.baseUrl + "query?v=20150910", {
    body: JSON.stringify({query: text, lang: "en", sessionId: "somerandomthing"}),
    headers: {
        'content-type': 'application/json',
        "Authorization": "Bearer " + accessToken,
    },
    method: 'POST',
})
    .then(response => response.json())
    .then(data => {
        console.log(data.result.fulfillment.speech);
        return data.result.fulfillment.speech;
    })
    .catch(error => console.error(error))

我不知道这是与DialogFlow V2进行通讯的正确方法吗？
请您让我知道我在做什么错，为什么它说我没有被授权，因为我已经通过上述命令进行了授权并且能够获得访问令牌！

I dont know if this is the right way to achieve a communication with DialogFlow V2? Please if you could let me know what I am doing wrong and why I it says I am not authorised since I am authorizing by the above commands and been able to get access token!

编辑：

经过几处更改，我的代码最终看起来像这样：

After few changes my code finally looks like this:

fetch("https://dialogflow.googleapis.com/v2beta1/projects/xxx/agent/sessions/xxx/:detectIntent", {
        body: JSON.stringify({queryInput: "Hello"}),
        headers: {
            'content-type': 'application/json',
            "Authorization": "Bearer xxxx",
        },
        method: 'POST',
    })
        .then(response => response.json())
        .then(data => {
            console.log(data.result.fulfillment.speech);
            return data.result.fulfillment.speech;
        })
        .catch(error => console.error(error))

我收到的新错误消息是：

and the new error message I get is:

{
  "error": {
    "code": 400,
    "message": "Invalid value at 'query_input' (type.googleapis.com/google.cloud.dialogflow.v2beta1.QueryInput), \"Hello\"",
    "status": "INVALID_ARGUMENT",
    "details": [
      {
        "@type": "type.googleapis.com/google.rpc.BadRequest",
        "fieldViolations": [
          {
            "field": "query_input",
            "description": "Invalid value at 'query_input' (type.googleapis.com/google.cloud.dialogflow.v2beta1.QueryInput), \"Saanko yhteystiedot?\""
          }
        ]
      }
    ]
  }
}

推荐答案

您没有显示正在使用的 baseUrl ，但这看起来像V1 API而不是V2 API。您应该将代码迁移到V2 。

You don't show the baseUrl you're using, but that looks like the V1 API rather than the V2 API. You should migrate your code to V2.

还要记住，访问令牌已过期，因此您需要定期生成一个新令牌。您无法请求长期令牌（这被认为是不安全的），但是应该让您的代码调用 gcloud auth print-access-token （或使用库来执行

Keep in mind, also, that the access token expires, so you will need to generate a new one periodically. You cannot request a "long lived" token (this is considered insecure), but should have your code call gcloud auth print-access-token (or use a library to do the same thing) before the previous one expires.

更新，将其移至V2之后：

Update based on your code once you've moved it to V2:

queryInput 参数不直接使用字符串。必须将其设置为 QueryInput对象。这是一个枚举，因此只能设置一个指定的字段。看来您想要文本字段，该字段需要 TextInput对象。

The queryInput parameter doesn't take a string directly. It must be set to a QueryInput object. This is an enum, so can only have one of the fields specified set. It looks like you want the text field which requires a TextInput object.

所以您的 body 参数可能可以这样设置：

So your body parameter might be setup something like this:

var body = {
  queryInput: {
    text: {
      text: "Hello",
      language: "en-US"
    }
  }
};
var bodyStr = JSON.stringify(body);

，然后在您的 request（）中进行设置选项。

and then set in your request() options.
