通过 Spring Social 使用图像创建 Facebook 事件

查看 spring 社交 facebook api，EventOperations 提供

    createEvent(java.lang.String name, java.lang.String startTime, 
                                                      java.lang.String endTime)

将事件发布到 facebook 的功能。

有没有办法发布活动的更多信息，例如活动图片和活动描述？

Looking over the spring social facebook api, EventOperations offers

    createEvent(java.lang.String name, java.lang.String startTime, 
                                                      java.lang.String endTime)

to post Events to facebook.

Is there a way to post more information for the event, like event image and event description?

查看createEvent方法，它当前不支持附件（事件图像）。然而，它确实调用 GraphApi publish 来实际发布事件：

public String createEvent(String name, String startTime, String endTime) {
    requireAuthorization();
    MultiValueMap<String, Object> data = new LinkedMultiValueMap<String, Object>();
    data.set("name", name);
    data.set("start_time", startTime);
    data.set("end_time", endTime);
    return graphApi.publish("me", "events", data);
}

graphApi.publish(...) 本身（在 Facebook 模板 )将支持任何东西作为 Facebook 准备接受的 {key,value} 对，因为它只是委托给 RestTemplate，并通过常规 HTTP POST 将所有 {key,value} 对提供给 Facebook ：

public String publish(String objectId, String connectionType, MultiValueMap<String, Object> data) {
    MultiValueMap<String, Object> requestData = new LinkedMultiValueMap<String, Object>(data);
    URI uri = URIBuilder.fromUri(GRAPH_API_URL + objectId + "/" + connectionType).build();
    Map<String, Object> response = getRestTemplate().postForObject(uri, requestData, Map.class);
    return (String) response.get("id");
}

因此您可以扩展 EventTemplate 并添加另一个 createEvent 方法，该方法将采用图像名称和图像文件路径，并将其作为附加的 {key,value} 添加到 data MultiMap 中：

data.set( "@" + imageName, "@" + imagePath )

因此该方法看起来接近于：

public String createEvent( String name, 
                           String startTime, 
                           String endTime,
                           String imageName,
                           String imagePath ) {   // or maybe even "File image", where you would derive the path
    requireAuthorization();
    MultiValueMap<String, Object> data = new LinkedMultiValueMap<String, Object>();
    data.set("name", name);
    data.set("start_time", startTime);
    data.set("end_time", endTime);

    data.set( "@" + imageName, "@" + imagePath );  // <<< adding this line

    return graphApi.publish("me", "events", data);
}

这当然不包括您可能想要执行的任何可能的验证等。。
一旦你完成了这项工作（这似乎非常简单），你可以将其捐赠/贡献回 Spring Social =>他们会很高兴:)

Looking at createEvent method, it does not currently support the attachment (event image). It does however call into GraphApi publish to actually publish the event:

public String createEvent(String name, String startTime, String endTime) {
    requireAuthorization();
    MultiValueMap<String, Object> data = new LinkedMultiValueMap<String, Object>();
    data.set("name", name);
    data.set("start_time", startTime);
    data.set("end_time", endTime);
    return graphApi.publish("me", "events", data);
}

graphApi.publish(...) itself ( which is implemented in FacebookTemplate ) would support anything as a {key,value} pair that Facebook is ready to accept, as it just delegates to the RestTemplate, and feeds all the {key,value} pairs to Facebook through a regular HTTP POST:

public String publish(String objectId, String connectionType, MultiValueMap<String, Object> data) {
    MultiValueMap<String, Object> requestData = new LinkedMultiValueMap<String, Object>(data);
    URI uri = URIBuilder.fromUri(GRAPH_API_URL + objectId + "/" + connectionType).build();
    Map<String, Object> response = getRestTemplate().postForObject(uri, requestData, Map.class);
    return (String) response.get("id");
}

Hence you can extend the EventTemplate and add another createEvent method, that would take an image name and an image file path, and would added it as an additional {key,value} to a data MultiMap:

data.set( "@" + imageName, "@" + imagePath )

Hence the method would look close to:

public String createEvent( String name, 
                           String startTime, 
                           String endTime,
                           String imageName,
                           String imagePath ) {   // or maybe even "File image", where you would derive the path
    requireAuthorization();
    MultiValueMap<String, Object> data = new LinkedMultiValueMap<String, Object>();
    data.set("name", name);
    data.set("start_time", startTime);
    data.set("end_time", endTime);

    data.set( "@" + imageName, "@" + imagePath );  // <<< adding this line

    return graphApi.publish("me", "events", data);
}

This of course does not include any possible validation that you might want to do, etc..
Once you have this working, which seems to be pretty straightforward, you can donate / contribute it back to Spring Social => they'd be very pleased :)
