Question

有这样的要求：

public GetJobsListExcel(jobs: JobViewModel[] ): Promise<string> {
        let JobIds: number[] = [];
        jobs.forEach(x => JobIds.push(x.JobId));
        let url = `/api/job/jobs-list-excel?jobIds=${JobIds}`;
        return this.http.get(url)
            .toPromise()
            .then(response =>
                response.text() as string
            );
    }

它会生成如下参考：/ api / job / jobs-list-excel？ JobIds = $ 1,2,3 e.t.c 你需要的是这样的：/ api / job / jobs-list-excel？ JobIds = 1美元？ JobIds = 2美元？ JobIds = $ 3

我试过大家，不出门，朝什么方向挖？谢谢。

Answer 1

我建议您将JobIds传递给API ,分隔的number列表作为字符串

let url = `/api/job/jobs-list-excel?jobIds=${JobIds.join(',')}`

服务器端split JobIds字符串,（逗号）

Answer 2

如果您需要在问题中提出多个JobIds查询字符串

，这可能会有效

let url = `/api/job/jobs-list-excel?JobIds=${JobIds.join('&JobIds=')}` 
// => "/api/job/jobs-list-excel?JobIds=1&JobIds=2&JobIds=3&JobIds=4"

如何在Angular 2中提出这样的请求？
