如何向 Facebook Marketing API 发起 POST 调用？

Question

我正在尝试从我的应用程序 POST 调用 Facebook 的图表 API。该方法的相关摘录是：

RestTemplate restTemplate = new RestTemplate();

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
headers.set("Authorization","Bearer "+ accessToken);

HttpEntity<EventSetVM> request = new HttpEntity<>(new EventSetVM(eventSetName), headers);

Map<String, String> params = new HashMap<>();
params.put("name", eventSetName);

String url = "https://graph.facebook.com/v2.8/" +
             businessManagerId +
             "/offline_conversion_data_sets";

EventSetVM eventSetVM = restTemplate.postForObject(url, request, EventSetVM.class, params);

我从 Firefox 的 RESTClient 得到的错误是

{
    "timestamp": 1487779045470,
    "status": 500,
    "error": "Internal Server Error",
    "exception": "org.springframework.web.client.HttpClientErrorException",
    "message": "400 Bad Request",
    "path": "<correct-path-with-no-parameters>"
}

这是怎么回事？

Answer 1

图表 API 要求在您的请求中使用明确的 "access_token" 参数。您需要在参数中添加 access_token 参数。
