 AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
SetAFHttpManger(manager, YES);

[self HUDShow:@"正在上传头像"];

__weak typeof(self) safeSelf = self;
[manager POST:BASE_HOST(REQUEST_EDIT_HEAD_IMAGE) parameters:dictionary constructingBodyWithBlock:^(id <AFMultipartFormData> formData) {

    NSData *data = UIImagePNGRepresentation(currentHeadImage);

    [formData appendPartWithFileData:data name:@"headImage" fileName:@"headImage.png" mimeType:@"image/png"];

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