Ios 使用AFN网络发送图像和其他参数

我正在用

AFNetworking

更新使用

ASIHTTPRequest

的旧应用程序代码。在我的例子中，我向

API

发送了一组数据，这些数据有不同的类型：Image和other

以下是我到目前为止采用的代码，实现API客户端，请求共享实例，准备params字典并将其发送到远程API：

NSMutableDictionary *params = [NSMutableDictionary dictionary];
[params setValue:@"Some value" forKey:aKey];

[[APIClient sharedInstance]
 postPath:@"/post"
 parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
     //some logic


 } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
     //handle error

 }];

当我想在

params

字典中添加图像时，会出现什么情况

使用

ASIHTTPRequest

，我通常会执行以下操作：

NSData *imgData = UIImagePNGRepresentation(anImage);

NSString *newStr = [anImageName stringByReplacingOccurrencesOfString:@"/"
                                                              withString:@"_"];



[request addData:imgData
    withFileName:[NSString stringWithFormat:@"%@.png",newStr]
  andContentType:@"image/png"
          forKey:anOtherKey];

我翻阅了

AFNetworking

文档，发现他们在

NSMutableRequest

中添加了图像，如下所示：

AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url];
NSData *imageData = UIImageJPEGRepresentation([UIImage imageNamed:@"avatar.jpg"], 0.5);
NSMutableURLRequest *request = [httpClient multipartFormRequestWithMethod:@"POST" path:@"/upload" parameters:nil constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) {
    [formData appendPartWithFileData:imageData name:@"avatar" fileName:@"avatar.jpg" mimeType:@"image/jpeg"];
}];

AFHTTPClient*httpClient=[[AFHTTPClient alloc]initWithBaseURL:url]；
NSData*imageData=UIImageJPEG表示法（[UIImage ImageName:@“avatar.jpg”]，0.5）；
NSMutableURLRequest*request=[httpClient multipartFormRequestWithMethod:@“POST”路径：@“/upload”参数：nil constructingBodyWithBlock:^（id formData）{
[formData appendPartWithFileData:imageData名称：@“avatar”文件名：@“avatar.jpg”mimeType:@“image/jpeg”]；
}];

---

我应该如何巧妙地将这些信息混合在一起，以便将图像数据集成到

APIClient

请求中？Thanx提前。

我使用相同的AFNetworking上传带有一些参数的图像。这个代码对我来说很好用。也许会有帮助

NSData *imageToUpload = UIImageJPEGRepresentation(uploadedImgView.image, 1.0);//(uploadedImgView.image);
if (imageToUpload)
{
    NSDictionary *parameters = [NSDictionary dictionaryWithObjectsAndKeys:keyParameter, @"keyName", nil];

    AFHTTPClient *client= [AFHTTPClient clientWithBaseURL:[NSURL URLWithString:@"http://------"]];

    NSMutableURLRequest *request = [client multipartFormRequestWithMethod:@"POST" path:@"API name as you have" parameters:parameters constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) {
        [formData appendPartWithFileData: imageToUpload name:@"image" fileName:@"temp.jpeg" mimeType:@"image/jpeg"];
    }];

    AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];

    [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject)
     {
         NSDictionary *jsons = [NSJSONSerialization JSONObjectWithData:responseObject options:kNilOptions error:nil];
         //NSLog(@"response: %@",jsons);

     }
                                     failure:^(AFHTTPRequestOperation *operation, NSError *error)
     {
         if([operation.response statusCode] == 403)
         {
             //NSLog(@"Upload Failed");
             return;
         }
         //NSLog(@"error: %@", [operation error]);

     }];

    [operation start];
}

NSData*imageToUpload=uiimagejpeg表示（上传edimgview.image，1.0）//（上传edimgview.image）；
如果（imageToUpload）
{
NSDictionary*参数=[NSDictionary Dictionary WithObjectsAndKeys:keyParameter，@“keyName”，nil]；
AFHTTPClient*客户端=[AFHTTPClient客户端WithBaseURL:[NSURL URLWithString:@]http://------"]];
NSMutableURLRequest*request=[客户端multipartFormRequestWithMethod:@“POST”路径：@“API名称如您所用”参数：参数constructingBodyWithBlock:^（id formData）{
[formData appendPartWithFileData:ImageToPload名称：@“image”文件名：@“temp.jpeg”mimeType:@“image/jpeg”]；
}];
AFHTTPRequestOperation*操作=[[AFHTTPRequestOperation alloc]initWithRequest:request]；
[操作setCompletionBlockWithSuccess:^（AFHTTPRequestOperation*操作，id响应对象）
{
NSDictionary*jsons=[NSJSONSerialization JSONObjectWithData:responseObject选项：针状体错误：nil]；
//NSLog（@“响应：%@”，JSON）；
}
失败：^（AFHTTPRequestOperation*操作，NSError*错误）
{
如果（[operation.response statusCode]==403）
{
//NSLog（@“上传失败”）；
返回；
}
//NSLog（@“错误：%@，[操作错误]）；
}];
[操作启动]；
}

祝你好运

在AFNetworking 2.0.1中，这段代码对我很有用

-(void) saveImage: (NSData *)imageData forImageName: (NSString *) imageName {
    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

    NSString *imagePostUrl = [NSString stringWithFormat:@"%@/v1/image", BASE_URL];
    NSDictionary *parameters = @{@"imageName": imageName};

    NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:imagePostUrl parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
        [formData appendPartWithFileData:imageData name:@"image" fileName:imageName mimeType:@"image/jpeg"];
    }];

    AFHTTPRequestOperation *op = [manager HTTPRequestOperationWithRequest:request success: ^(AFHTTPRequestOperation *operation, id responseObject) {
        DLog(@"response: %@", responseObject);
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        DLog(@"Error: %@", error);
    }];
    op.responseSerializer = [AFHTTPResponseSerializer serializer];
    [[NSOperationQueue mainQueue] addOperation:op];
}

而不是

op.responseSerializer = [AFHTTPResponseSerializer serializer];

您好，您将图像的

键放在哪里？Thanx.@“image”是您要上载的任何图像的键。我应该在path参数中特别添加什么？AFHTTPClient被拆分为。它在2.0中不再存在。
op.responseSerializer = [AFHTTPResponseSerializer serializer];
