SWIFT URL 字符串构建

Question

如何构建如下 URL:

/sap/opu/odata/SAP/ZTM_FOR_MOBILITY_SRV/BusinessPartnerSet('BP-CR-EM01')/?$format=json

我特别想要零件 - BusinessPartnerSet('BP-CR-EM01')。

BP-CR-EM01 值为动态值。

let newUrl = url  + "'\(businessPartners[myIndex].partnerId)'"

url 具有固定的 URL 和 + 运算符，后跟动态值。请帮我提出你的建议。

我推荐使用URLComponents

var components = URLComponents(string: "http://mycompany.com")!
components.path = "/sap/opu/odata/SAP/ZTM_FOR_MOBILITY_SRV/BusinessPartnerSet('\(businessPartners[myIndex].partnerId)')/"
components.queryItems = [URLQueryItem(name: "$format", value:"json")]
if let url = components.url {
    print(url)
    // or if you need the string
    print(url.absoluteString)
}
