您好，我是 swift4 的新手，并试图通过 alamofire 库以 swift4 语言调用多部分表单数据请求？下面是我的代码

Alamofire.upload(multipartFormData: { multipartFormData in
            multipartFormData.append("1422".data(using: String.Encoding.utf8)!, withName: "u_id")
            multipartFormData.append("How???".data(using: String.Encoding.utf8)!, withName: "firstname")
            multipartFormData.append("We are woking on it!!".data(using: String.Encoding.utf8)!, withName: "description")
        }, to: "URL_TOcall", encodingCompletion: { result in
            print("result  = \(result)")
            switch result {
            case .success(request: let request, streamingFromDisk: false, streamFileURL: nil):
                //Success code
                break

            case .failure:
                print("failed api calling")
                break


            case .success(let request, true, _):
                //Code here
                break

            case .success(let request, _, _):
                // Code here
                break
            }


        })
}

我已经解决了我的问题，这是我没有做的太愚蠢和小事，但是在将allowLossyConversion: false添加到我的字符串转换之后，就解决了问题。

{
 //corrected indentation for code

 Alamofire.upload(multipartFormData: { multipartFormData in
        multipartFormData.append("1422".data(using: String.Encoding.utf8, allowLossyConversion: false)!, withName: "u_id")
        multipartFormData.append("How???".data(using: String.Encoding.utf8, allowLossyConversion: false)!, withName: "firstname")
        multipartFormData.append("We are woking on it!!".data(using: String.Encoding.utf8, allowLossyConversion: false)!, withName: "description")
    }, to: "URL_TOcall", encodingCompletion: { result in
        print("result  = \(result)")
        switch result {
        case .success(request: let request, streamingFromDisk: false, streamFileURL: nil):
            //Success code
            break

        case .failure:
            print("failed api calling")
            break


        case .success(let request, true, _):
            //Code here
            break

        case .success(let request, _, _):
            // Code here
            break
        }
    })
}
