如何在swift中解析时在参数中添加post-api请求

Question

这是我的api请求：

{
"billDetails": {
"billerId":"EPDCLOB00AN232",
"customerParams":[{"name":"Service Number","value":"116515M025033"}]
}
}

这是代码：

func billerFetchService(){
let parameters = ["billDetails": {
"billerId" : "EPDCLOB00ANP01",
"customerParams" : [{"name":"Service Number","value":"116515M025007621"}]
}
] as [String : Any]

let url = URL(string: "https://app.com/Fetch/fetch")
var req =  URLRequest(url: url!)
req.httpMethod = "POST"
req.addValue("application/json", forHTTPHeaderField: "Contet-Type")
req.addValue("application/json", forHTTPHeaderField: "Accept")
guard let httpBody = try? JSONSerialization.data(withJSONObject: parameters, options: .prettyPrinted) else {return}
req.httpBody = httpBody
let session = URLSession.shared
session.dataTask(with: req, completionHandler: {(data, response, error) in
if response != nil {
// print(response)
}
if let data = data {
do{
var json = try JSONSerialization.jsonObject(with: data, options: .mutableContainers) as! [String: Any]
print("fetching json (json)")
}catch{
print("error")
}
}
}).resume()
}

如果我在parameters错误中添加这样的内容

一行上的连续语句必须用"；"分隔
插入"；"预期表达式

在我犯错误的地方，请帮助我进行代码

Answer 1

您需要

let parameters = ["billDetails": [
"billerId" : "EPDCLOB00ANP01",
"customerParams" : [["name":"Service Number","value":"116515M025007621"]]]]

请将您的参数设置为此

let parameters = ["billDetails":
[
"billerId": "EPDCLOB00ANP01",
"customerParams" : ["name":"Service Number","value":"116515M025007621"]
]
] as [String : Any]
