【问题标题】：Swift - multipart/form-data POST request(upload) with and without imageSwift - 带和不带图像的多部分/表单数据 POST 请求（上传）

【问题描述】：

我正在尝试使用以下代码上传不带图像的配置文件数据并收到 400 个错误请求。而且，当我上传带有文件图像的配置文件数据时，也会出现同样的错误。

有些格式不匹配请帮忙！！！

Postman Request Image

var body = NSMutableData()
body.append("Content-Disposition: form-data; name=\"profileData\"".data(using: String.Encoding.utf8)!)
body.append("\(inputStr)\r\n".data(using: String.Encoding.utf8, allowLossyConversion: true)!)
body.append("Content-Disposition: form-data; name=\"file\"".data(using: String.Encoding.utf8)!)
body.append("\("")\r\n".data(using: String.Encoding.utf8, allowLossyConversion: true)!)
request.httpBody = body as Data

【解决方案1】：

request.httpMethod = "POST"
        request.setValue("multipart/form-data; boundary=\(boundary)", forHTTPHeaderField: "Content-Type")
        let body = NSMutableData()
        body.append("--\(boundary)\r\n".data(using: String.Encoding.utf8)!)




        let strPhotoUrl = photourl
        let mimetype = "image/jpeg"
        let readPath = Utility.getPhotofolder().stringByAppendingPathComponent(pathComponent:strPhotoUrl) // pass the path of the image 



        let image    = UIImage(named: strPhotoUrl)
        if (image == nil)
        {
            print("image is nil")
            return
        }
        let image_data = UIImagePNGRepresentation(image!)
        if(image_data == nil)
        {   
            return
        }

        body.append("Content-Disposition:form-data; name=\"attachedImage\"; filename=\"\(photourl)\"\r\n".data(using: String.Encoding.utf8)!)
        body.append("Content-Type: \(mimetype)\r\n\r\n".data(using: String.Encoding.utf8)!)
        body.append(image_data!)

        body.append("\r\n".data(using: String.Encoding.utf8)!)

        body.append("--\(boundary)--\r\n".data(using: String.Encoding.utf8)!)

        request.httpBody = body as Data
