用Moya Swift完整示例上传图像多部分
提问于 2017-09-12 20:55:54
如何使用Moya Swift中的多部分/表单数据上载图像
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
}
}但是我需要用"profileImage“键将imageData发送到体内

使用MoyaVersion10.0.0及以上多部分上传图像
1-将要上载到MultipartFormData数组中的文件放到
// 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 []
}
}这个方法的任务类型是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)
}
}使用MoyaVersion9.0.0及以下多部分上传图像
1-将要上载到MultipartFormData数组中的文件放到
// 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-添加multipartBody提供程序以请求所需方法的主体
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-使此方法的任务类型是上载。
var task: Task {
switch self {
case .registerWith:
// multipartBody that in First step
return .upload(.multipart(multipartBody))
}

Hear是使用Moya在快速4.2中上传图像的代码
1)在任务中，moya的部分变化类似于下面的函数
var task: Task {
switch self {
case .signup(let params):
var formData = [MultipartFormData]()
for (key, value) in params {
if let imgData = value as? Data {
formData.append(MultipartFormData(provider: .data(imgData), name: key, fileName: "testImage.jpg", mimeType: "image/jpeg"))
} else {
formData.append(MultipartFormData(provider: .data("\(value)".data(using: .utf8)!), name: key))
}
}
return .uploadMultipart(formData)
case .signIn(let params), .resetPassword(let params), .changePassword(let params), .socialLogin(let params):
return .requestParameters(parameters: params, encoding: URLEncoding.default)
}
}2)如何生成参数
var params = [String:Any]()
params["first_name"] = self.txtFirstName.text
params["last_name"] = self.txtLastName.text
params["email"] = self.txtEmailAddess.text
params["password"] = self.txtPassword.text
if self.imgProfilePic.image != nil {
if let imgData:Data = self.imgProfilePic.image!.pngData() {
params["picture"] = imgData
}
}
else {
params["picture"] = ""
}并将此参数进一步传递给API调用。

您需要将"name："profile_picture"“改为"name：”profileImage“，尝试以下操作。
