AFNetworking 3.0 Multipart 表单数据上传图片报错
AFNetworking 3.0 Multipart form data for uploading image error
我一直在尝试使用多部分表单数据 afnetworking 3.0 将图像上传到我的 AWS 服务器，但显然，我尝试上传的每张图像都以失败告终。代码写在 objective-c 中。
- (NSURLSessionUploadTask *)uploadImageTask:(NSMutableDictionary *)dictionary
{
NSString *s3BucketUrl = [dictionary objectForKey:@"s3BucketUrl"];
NSData *imageData = [dictionary objectForKey:@"imageData"];
NSString *contentType = [dictionary objectForKey:@"contentType"];
NSString *filename = [dictionary objectForKey:@"filename"];
NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:s3BucketUrl parameters:dictionary constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileData:imageData name:@"file" fileName:filename mimeType:contentType];
} error:nil];
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
NSURLSessionUploadTask *uploadTask = [[NSURLSessionUploadTask alloc] init];
uploadTask = [manager
uploadTaskWithStreamedRequest:request
progress:^(NSProgress * _Nonnull uploadProgress) {
// This is not called back on the main queue.
// You are responsible for dispatching to the main queue for UI updates
dispatch_async(dispatch_get_main_queue(), ^{
//Update the progress view
});
}
completionHandler:^(NSURLResponse * _Nonnull response, id _Nullable responseObject, NSError * _Nullable error) {
if (!error) {
if (self.delegate != nil && [self.delegate respondsToSelector:@selector(onUploadImageTask:)])
{
[self.delegate onUploadImageTask:nil];
}
} else {
if (self.delegate != nil && [self.delegate respondsToSelector:@selector(onUploadImageTask:)])
{
[self.delegate onUploadImageTask:error];
}
}
}];
[uploadTask resume];
return uploadTask;
}
我得到的错误是
Error Domain=com.alamofire.error.serialization.response Code=-1011 "Request failed: bad request (400)" UserInfo={NSUnderlyingError=0x170248940 {Error Domain=com.alamofire.error.serialization.response Code=-1016 "Request failed: unacceptable content-type: application/xml" UserInfo={com.alamofire.serialization.response.error.response= { URL: https://....s3.amazonaws.com/ } { status code: 400, headers {
