我正在设置一些Azure HTTP触发器函数来接收JSON数据

我希望访问并将一些数据向前传递到服务总线队列，以便进行下游处理

我已经能够将出站绑定添加到服务总线，但是在没有得到500内部服务器错误的情况下，无法放置代码以将来自HTTp触发器函数的消息放置在队列上。这是由于函数的异步性质造成的吗

如何实现call-HTTP-Trigger-that-passes-data-forwards-to-a-ServiceB总线队列功能

module.exports = async function (context, req) {
    context.log('JavaScript HTTP trigger function processed a request.');

    if (req.query.name || (req.body && req.body.name)) {

        context.log('Incoming data from Webhook' + req);
        context.bindings.outputSbMsg = "Message placed on Service Bus Queue";
        context.log('Message placed on Service Bus Queue');

        context.res = {
            // status: 200, /* Defaults to 200 */
            body: "Hello " + (req.query.name || req.body.name)
        };
    }
    else {
        context.res = {
            status: 400,
            body: "Please pass a name on the query string or in the request body"
        };
    }
};

我确实像您一样尝试部署，但不幸的是，即使只是在运行get查询时，我仍然会遇到500个内部服务器错误

以下是文件在monent中的外观：

配置出站服务总线队列时，我发现从现有名称空间中选择服务总线队列名称空间很奇怪。在下一步中，我无法选择实际队列，即使之前已经创建了观测sbq
输入其他队列名称（如testqueue）也不起作用。它没有被创建，并且发生相同的500内部服务器错误，即使是在门户中直接测试功能时也是如此
错误消息：

这是否意味着没有使用/部署local.settings.json文件

然后，您将发现一条消息进入服务总线队列：

看来你的代码没有问题，你能显示你的function.json文件吗？你是在本地还是在azure上运行代码？@tobiasperson所以你在azure上运行？@tobiasperson它应该有一些错误输出，你能展示它吗？我在Visual Studio代码中编写代码并将其上传到现有的函数App/Function。我将文件的内容添加到上面的原始帖子中。我看不出它们有什么奇怪的地方，现在你们的代码和我的代码有什么不同了。“选择现有服务总线队列”问题如何？@TobiasPersson Ok，请检查详细信息错误。首先，转到
