我正在寻找一种方法来执行这个

curl -u username:password -H "Content-Type: application/binary" \
   --data-binary @file.dat -X POST \
   "https://helpdesk.zendesk.com/api/v2/uploads.json?filename=myfile.dat&token={optional_token}"

我试过用这个

[afnetworkmanager POST:url parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {

        [formData appendPartWithFileData:attachment.attachmentData name:@"image" fileName:attachment.fileName mimeType:attachment.mimeType];

    } success:^(AFHTTPRequestOperation *operation, id responseObject) {
       // TODO:

    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
       // TODO:
    }];

但这并没有帮助。目前我收到一条错误消息

{
>     "Cache-Control" = "max-age=0, private, must-revalidate";
>     Connection = "keep-alive";
>     "Content-Length" = 345;

>     "X-Zendesk-API-Warn" = "Removed restricted keys [\"image\"] from parameters according to whitelist"; } },

> NSLocalizedDescription=Request failed: unacceptable content-type:

我不明白我错在哪里。

我最终通过使用 AFURLSessionManager 来实现它。这是完整的代码：

NSString *uploadAttachmentURL = @"https://mydomain.zendesk.com/api/v2/uploads.json?filename=screenshot.jpeg";

        NSData *imageData = UIImageJPEGRepresentation(image, 1.0);

        NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
        _afHTTPSessionManager = [[AFHTTPSessionManager alloc] initWithSessionConfiguration:configuration];

        // hack to allow 'text/plain' content-type to work
        NSMutableSet *contentTypes = [NSMutableSet setWithSet:_AFOpManager.responseSerializer.acceptableContentTypes];
        [contentTypes addObject:@"text/plain"];
        _afHTTPSessionManager.responseSerializer.acceptableContentTypes = contentTypes;

        [_afHTTPSessionManager.requestSerializer setAuthorizationHeaderFieldWithUsername:@"[USERNAME]" password:@"[PASSWORD]"];



        [_afHTTPSessionManager POST:uploadAttachmentURL parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
            [formData appendPartWithFileData:imageData name:@"screenshot" fileName:@"photo.jpg" mimeType:@"image/jpeg"];
        } success:^(NSURLSessionDataTask *task, id responseObject) {
            DDLogError(@"screenshot operation success!  %@", responseObject);
        } failure:^(NSURLSessionDataTask *task, NSError *error) {
            DDLogError(@"Operation Error: %@", error);
        }];

NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];

    configuration.HTTPAdditionalHeaders = @{@"CS090-Version":[NSString stringWithFormat:@"ios_%@",VERSION];

    AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc]initWithSessionConfiguration:configuration];


    manager.responseSerializer.acceptableContentTypes  = [NSSet setWithObject:@"text/html"];

    NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:apiURL parameters:nil constructingBodyWithBlock:nil error:nil];

    NSURLSessionUploadTask *uploadTask;
    uploadTask = [manager uploadTaskWithRequest:request fromData:imgData progress:nil completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {
        if (error) {
            NSLog(@"Error: %@", error);
        } else {
            NSLog(@"%@ %@", response, responseObject);
        }
    }];

    [uploadTask resume];
