Question

I have an Azure Function with route as "project/{category}" which SQLs to my Cosmos DB. So my function.json has

"sqlQuery": "SELECT * from c where c.category = {category}"

Everything is fine when the HTTP endpoint parameter for category has no space like "http://.azurewebsites.net/api/project/rainbow" or "http://.azurewebsites.net/api/project/nospace". It is able to SQL category = rainbow or category = nospace.

But when I have an HTTP endpoint parameter like "http://.azurewebsites.net/api/project/rain%20bow" or "http://.azurewebsites.net/api/project/yes%20space". It does not show anything.

How do I handle parameters to be used in my javascript Azure Function? Replace %20 of context.bindingData.category to actual spaces " ", then run the sqlQuery.

Here is my code

module.exports = async function (context, req) {
    if (context.bindingData.category) {
        context.res = {
            status: 200, /* Defaults to 200 */
            body: context.bindings.inputDocument,
            headers: {
                'Content-Type': 'application/json'
            }
        };
    }
    else {
        context.res = {
            status: 400,
            body: "Error"
        };
    }
};

alpha是Route Constraint，表示Matches uppercase or lowercase Latin alphabet characters (a-z, A-Z)。这是一个可选选项。

现在HttpTrigger有一个限制，它不支持带有扩展名的请求（有关详细信息，请参见this）。

如问题中所述，您可以使用代理来解决此限制，但是您确实需要从路线中删除alpha约束。
