Google Calendar API - PATCH返回200正常但未实际更新事件

我试图将我的webapp的日历与Google日历集成。我正在成功验证用户身份，能够从Google读取事件并从Google中删除事件。我在从我的应用更新事件到Google时遇到问题。Google Calendar API - PATCH返回200正常但未实际更新事件

我使用补丁的方法描述 here我只是想修改我的API调用发送（而不是在PUT调用，它需要对这一事件的所有字段）的字段。

我的Perl代码创建了一个JSON对象来表示我想要更改的内容。然后我向Google提交PATCH请求，并且我收到状态200 OK并从Google返回事件资源。我收到的回应应该是修改的事件资源，但是我修改的字段在响应中未被修改。当我检查Google日历本身时，我再次看到该事件未被修改。

我很困惑，为什么当事件没有更新时，我得到200 OK响应而不是错误。奇怪的是，在响应中，“更新”时间戳记属性已更新，但汇总字段没有更新。

my $ua = LWP::UserAgent->new; 

    my $url = "https://www.googleapis.com/calendar/v3/calendars/primary/events/${id}?access_token=${access_token}"; 

    my $resource{"summary"} = "$g{summary}"; 

    $resource = encode_json(\%resource); 

    my $headers = HTTP::Headers->new(); 
    $headers->header(If_Match => "$etag"); 

    my $request = HTTP::Request->new('PATCH',$url,$headers,$resource); 

    my $response = $ua->request($request); 

    my $status = $response->status_line; 

    my $result = decode_json($response->decoded_content);

从结果“ETAG”值如我所料，这表明日历事件正在（有点）修改谷歌更新。

一些数据::自卸车跟踪：

请求：

$VAR1 = bless({ 
       '_content' => '{"summary":"End of season function MODIFIED"}', 
       '_uri' => bless(do{\(my $o = 'https://www.googleapis.com/calendar/v3/calendars/primary/events/<eventID>?access_token=<access_token>')}, 'URI::https'), 
       '_headers' => bless({ 
             'if-match' => '<etag>' 
             }, 'HTTP::Headers'), 
       '_method' => 'PATCH' 
       }, 'HTTP::Request');

       '_request' => bless({

             '_headers' => bless({ 
                   'user-agent' => 'libwww-perl/6.01', 
                   'if-match' => '<etag>' 
                  }, 'HTTP::Headers'), 
             '_method' => 'PATCH', 
             '_uri_canonical' => $VAR1->{'_request'}{'_uri'} 
             }, 'HTTP::Request') 
       }, 'HTTP::Response');

有人能看到我在做什么错？我确信Google正在接受我的PATCH请求，但由于某种原因我没有看到我想要修改的字段。我已经尝试在其testing page上提交完全相同的JSON对象，并且没有问题使其工作...

我发现解决方案纯粹是通过试验和错误 - 将“Content-Type”标头添加到HTTP标头似乎做的伎俩：

my $headers = HTTP::Headers->new(); 
    $headers->header(If_Match => "$etag"); 
    $headers->header(Content_Type => "application/json");
