ios - 上传图片 Multipart With Moya Swift Fully 例子

Question

如何在带有 Moya 的 Swift 中使用 multipart/form-data 上传图像

我的代码

var multipartBody: [MultipartFormData]? {
    switch self {
    case .registerWith(let registrationObject ):
        if let profileImageData = registrationObject.profileImageData{
        return [MultipartFormData(provider: .data(profileImageData), name: "profile_picture", fileName: "\(registrationObject.phone).jpg",
            mimeType: "image/jpeg")]
        }
        return nil
    default:
        return nil
    }
}

var task: Task {
    switch self {
    case .registerWith:
        if let multipartBody = multipartBody {
            return .upload(.multipart(multipartBody))
        }else{
            return .request
        }
    default:
        return .request
    }
}

但我需要使用键“profileImage”在正文中发送图像数据

To upload an image in Multipart using Moya version 10.0.0 and above

1-将要上传的文件放在MultipartFormData数组中

// put files in MultipartFormData Arry  
   var multipartBody :[Moya.MultipartFormData]?{
    switch self {
    case .registerWith(let imageData , let name ,let description  ):
        // any additional body data or body parms
        let nameDataProvider = MultipartFormData(provider: .data(name.data(using: .utf8)!), name: "name")
        let emailDataProvider = MultipartFormData(provider: .data(email.data(using: .utf8)!), name: "email")
        // image want to upload it or file as a MultipartFormData
        let imageDataProvider = Moya.MultipartFormData(provider: MultipartFormData.FormDataProvider.data(imageData), name: "avatar", fileName: "photo.jpg", mimeType: "image/jpeg")
            return [ imageDataProvider , descriptionDataProvider ]
    default:
        return []
    }
}

2-使该方法的任务类型为uploadMultipart

var task: Task {
    switch self {
    case .registerWith:
        // for each method multi part use its multipartBody that declared it in step one needed
        return .uploadMultipart(multipartBody!)
    default:
        guard let parameters = self.parameters else {
            return .requestPlain
        }
        return .requestParameters(parameters: parameters.values, encoding: parameters.encoding)
    }
}

To upload an image in Multipart using Moya version 9.0.0 and below

1-将要上传的文件放在MultipartFormData数组中

// put files in MultipartFormData Arry  
var multipartBody: [MultipartFormData]? {
     switch self {
          case .registerWith(let imageData , let name ,let description  ):
              return [MultipartFormData(provider: .data(imageData),
             name: "profile_picture", fileName: "fileName", mimeType: "image/jpeg")]
              default:
               return nil
       } 
}

2- 将 multipartBody 的提供者添加到您需要的方法的请求体中

var parameters: [String: Any]? {
     switch self {
          case .registerWith(let registrationObject ):
          var body = registrationObject.toJSON()!
          // add the file in body 
          body["profile_picture"] = multipartBody?[0].provider
          return body
     }
}

3-使该方法的任务类型为上传

var task: Task {
       switch self {
           case .registerWith:
              //  multipartBody that in First step
             return .upload(.multipart(multipartBody))
        }
}
