Azure Bot Service Direct Line API v3.0在开始对话时不断抛出403错误

Question

我一直在尝试将Azure Direct Line API v3.0用于机器人。然而，似乎我不再启用对话，因为我在APi呼叫上收到403消息。这是我的电话：

CREATE TYPE days_of_the_week as enum (
    'Sunday',
    'Monday',
    'Tuesday',
    'Wednesday',
    'Thursday',
    'Friday',
    'Saturday'
);

CREATE TABLE company (
    id SERIAL PRIMARY KEY NOT NULL,
    company_name CHARACTER VARYING(1024) NOT NULL
);

CREATE TABLE company_active (
    id_company integer NOT NULL REFERENCES company(id) ON DELETE CASCADE,
    days days_of_the_week NOT NULL
);

ALTER TABLE company_active
ADD CONSTRAINT company_active_unique UNIQUE (id_company, days);

INSERT INTO company (company_name) VALUES ('test');

INSERT INTO company_active (id_company, days)
SELECT id, 'Monday'::days_of_the_week
FROM company;

INSERT INTO company_active (id_company, days)
SELECT id, 'Tuesday'::days_of_the_week
FROM company;

请注意，过去这几天都会工作。我有通过此API创建的活动的几个活动记录。

但是现在我甚至在获取令牌时不断收到此错误消息：

$.ajax({
        url: "https://directline.botframework.com/v3/directline/tokens/generate",
        method: "POST",
        crossDomain: true,
        cache: false,
        beforeSend: function (xhr) {
            /* Authorization header */
            xhr.setRequestHeader ("Authorization", "Basic " + btoa("Bearer:GI3UQr2GYoA.cwA.wHo.h1AyNQKXSESWZGFrf-yf_Cm3XwDRy38Yn-xzgUton-E"));
        },
        success: function (data) {

        },
        error: function (jqXHR, textStatus, errorThrown) {

        }
    });

我正在使用免费订阅计划，我还剩7天。此外，我已检查订阅状态，其活动状态。我也有超过140美元的信贷。

请让我知道我做错了什么，为什么这会突然停止工作？

提前致谢。

阅读MS提供的有关身份验证的文档：https://docs.microsoft.com/en-us/azure/bot-service/rest-api/bot-framework-rest-direct-line-3-0-authentication?view=azure-bot-service-3.0

它说：

Authorization: Bearer SECRET_OR_TOKEN

所以改变这一行：

xhr.setRequestHeader ("Authorization", "Basic " + btoa("Bearer:GI3UQr2GYoA.cwA.wHo.h1AyNQKXSESWZGFrf-yf_Cm3XwDRy38Yn-xzgUton-E"));

要：

xhr.setRequestHeader ("Authorization", "Bearer GI3UQr2GYoA.cwA.wHo.h1AyNQKXSESWZGFrf-yf_Cm3XwDRy38Yn-xzgUton-E");

它工作正常！
