如何为将字符串数组作为参数的 .Net Core 3.1 webapi 服务调用定义路由？

Question

I'm create a.NetCore 3.1 Web API Service.

I am having difficulties figuring out the correct routing definition for the service call.

Consider the following definition:

[HttpPut]
[Route("{paramA}/{paramB}")]
public void Sample(string paramA, string[] paramB)
{
}

What is the correct way to define my routing parameters when passing either an array of strings? Should I be using List instead?

Answer 1

I suggest that you could pass the array list by query string:

[HttpPut]   
[Route("{paramA}")]
public void Sample([FromRoute]string paramA, [FromQuery]string[] paramB)
{
}

Send Request like: https://localhost:5001/xxxxxx/aaa?paramB=ss&paramB=sd .

Result:

I recomend you to pass the Arraay strings on the body of the request in a HttpPost, this is the part of the request where you don't have character limitations, when in the url of the query you will have something like 300 character limits.

For example:

HttpPost]
[Route("MyArrayStrings")]
public async string MyArrayStrings([FromBody] string content)
{
    return content;
}

And then, you can use Newtonsoft for serialize the data when sending the request, and for Deserialize when received.
