【问题描述】：

这是我的代码

 -(void)uploadNewImageWithURL:(NSString *)strURL andImage:(UIImage *)image andImageNameWithExtension:(NSString *)strImageName
NSString *path = strURL;
NSData *imageData = UIImageJPEGRepresentation(image, 0.5);

NSDictionary *parameters = @@"booktitle":@"TestUpload", @"author":@"Harry", @"booktype": @"NF", @"message":@"Test for upload1", @"isbn": @"42000004", @"uploadfile":imageData;
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"application/json"];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
[manager POST:path parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) 
    if(image)
        [formData appendPartWithFileData:imageData name:@"image" fileName:strImageName mimeType:@"image/jpeg"];

    
 success:^(AFHTTPRequestOperation *operation, id responseObject) 
    NSLog(@"success = %@", responseObject);
 failure:^(AFHTTPRequestOperation *operation, NSError *error) 
    NSLog(@"error = %@", error);
    NSLog(@"Response = %@", operation);
];

这是回复

【问题讨论】：

manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"application/json"]; responseSerializer 应该是 requestSerializer

【参考方案1】：

您可以使用以下代码通过 AFNetworking 上传图片。

AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:[NSURL URLWithString:siteAPIURL]];
manager.requestSerializer = [AFHTTPRequestSerializer serializer];
manager.responseSerializer = [AFJSONResponseSerializer serializer];

if (headers != nil)

    NSArray *allHeaders = [headers allKeys];

    for (NSString *key in allHeaders)
    
        [manager.requestSerializer setValue:[headers objectForKey:key] forHTTPHeaderField:key];
    




AFHTTPRequestOperation *op = [manager POST:serviceName parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> formData)

    //do not put image inside parameters dictionary as I did, but append it!
    [formData appendPartWithFileData:imgData name:@"profile_picture" fileName:@"photo.jpg" mimeType:@"image/jpeg"];
 success:^(AFHTTPRequestOperation *operation, id responseObject) 
    NSLog(@"Success: %@ ***** %@", operation.responseString, responseObject);
    NSLog(@"JSON: %@", responseObject);

    if (success != nil)
    
        success(operation,responseObject);
    
 failure:^(AFHTTPRequestOperation *operation, NSError *error) 

    if (failure != nil)
    
        failure(operation,error);
    
];
[op start];

【讨论】：

在android中我们发送的是图像文件而不是图像数据（NSdata），那么我们如何在ios中实现这一点？
