AFNetworking 3.0 multipartFormRequestWithMethod appendPartWithFileData 丢失请求正文和标头

Question

图像的分段上传在 AFNetwrking 1.0 上运行良好，我需要升级到 3.0。但是，请求参数和正文消失了。好像是在 AFURLRequestSerialization.m 中声明：

[self.request setHTTPBodyStream:self.bodyStream]

即使部件和主体存在于self.bodyStream 中。 setHTTPBodyStream 似乎没有返回错误。

这是代码：

AFHTTPRequestSerializer *requestSerializer = [AFHTTPRequestSerializer serializer];

NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];

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

manager.responseSerializer = [AFHTTPResponseSerializer serializer];

manager.securityPolicy.allowInvalidCertificates = YES; // not recommended for production

manager.securityPolicy.validatesDomainName = NO;

[requestSerializer setValue:@"multipart/form-data" forHTTPHeaderField:@"content-type"];

NSMutableURLRequest *request = [requestSerializer multipartFormRequestWithMethod:@"POST" URLString: ServerPath
                    parameters:sendDictionary constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {

[formData appendPartWithFileData: imageData name:@"file" fileName:@"temp.jpeg" mimeType:@"image/jpeg"];
                         } error:nil];

[request setTimeoutInterval:20000];


NSURLSessionUploadTask *uploadTask;

NSLog(@"Request body %@", [[NSString alloc] initWithData:[request HTTPBody] encoding:NSUTF8StringEncoding]); NSLog(@"Request HTTP Headers: %@", request.allHTTPHeaderFields); NSLog(@"%@", [request HTTPBody]);

uploadTask = [manager

AFNetwrking 3.0 显然必须从 Swift 代码中使用，因为它不再支持手动内存管理。不幸的是，您必须重写 Objective C 代码。
