swift - 如何从Swift中的字符串中删除单引号？

我从API响应接收值，如下所示

{
    "first_name" = "active EQ 'true'";
}

我需要在另一个API中将该值作为查询参数发送。但是当发送请求时，我看到URL没有被编码。我希望active EQ 'true'应该被URL编码为active%20EQ%20%27true%27。
我试过了。我看到反斜杠被添加为转义符，但没有按预期编码。

let k = "active EQ 'true'"
let j = k.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)
print("j is \(j)")

我期望输出为addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed) and it resulted in "active%20EQ%20\'true\'，但实际输出为active%20EQ%20%27true%27

最佳答案

先从字符串中省略“'”。检查以下代码：

let k = "active EQ 'true' "
let i = k.replacingOccurrences(of: "'", with: "")
let j = i.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)
print("j is \(j!)")
