在 facebook 营销 api leadgen_context_cards 边缘不接受 cover_photo

Question

我正在关注 https://developers.facebook.com/docs/marketing-api/guides/lead-ads/create/v2.8 以创建线索广告的背景卡片。文档说它将接受 cover_photo 字段。但是，如果我们尝试使用以下参数

从 Graph API Explorer 创建上下文

https://developers.facebook.com/tools/explorer/xxxxxx?method=POST&path=<PAGE_ID>%2Fleadgen_context_cards&version=v2.8&title=sample-title-1&style=PARAGRAPH_STYLE&content=[%22sample%20content%201%22]&button_text=Get%20Started&cover_photo=http://xxxxx.s3.amazonaws.com/sample/sampleimage.png

显示以下内容

{
  "error": {
    "message": "An unknown error has occurred.",
    "type": "OAuthException",
    "code": 1,
    "fbtrace_id": "xxxxxx"
  }
}

如果我们点击 fgtrace_id 它会显示以下内容

{
  "error": {
    "message": "(#803) Some of the aliases you requested do not exist: xxxxx",
    "type": "OAuthException",
    "code": 803,
    "fbtrace_id": "yyyyyy"
  }
}

如果我们删除 cover_photo 参数，我们就能够创建上下文卡片。

谢谢。

我试过上传实际的图像文件。仍然面临同样的问题。以下是代码和响应。

        HttpClient httpClient = HttpClientBuilder.create().build();
        HttpPost httppost = new HttpPost(GRAPH_FACEBOOK_LEADGEN_CONTEXT_CARDS);

        File file = new File(IMAGE_PATH);
        ContentBody cbFile = new FileBody(file, ContentType.create(MimeTypeUtils.IMAGE_PNG_VALUE));

        MultipartEntityBuilder builder = MultipartEntityBuilder.create();
        builder.addTextBody("access_token", ACCESS_TOKEN);
        builder.addTextBody("title", "sample-title-1");
        builder.addTextBody("style", "PARAGRAPH_STYLE");
        builder.addTextBody("content", "['sample-title-1']");
        builder.addTextBody("button_text", "Get Started");
    // builder.addPart("cover_photo", cbFile);
    // builder.addBinaryBody("cover_photo", file);
    // builder.addBinaryBody("cover_photo", file, ContentType.create(MimeTypeUtils.IMAGE_PNG_VALUE),IMAGE_PATH);
    // builder.addBinaryBody("cover_photo", new FileInputStream(file));

    httppost.setEntity(builder.build());
    System.out.println("executing request " + httppost.getRequestLine());
    HttpResponse response = httpClient.execute(httppost);
    HttpEntity resEntity = response.getEntity();

    System.out.println(response.getStatusLine());
    if (resEntity != null) {
        System.out.println(EntityUtils.toString(resEntity));
    }

回复：

使用以下代码，我可以创建上下文卡片。但是封面照片不见了。

URIBuilder uriBuilder = new URIBuilder(
                GRAPH_FACEBOOK_LEADGEN_CONTEXT_CARDS);
        uriBuilder.setParameter("access_token", ACCESS_TOKEN);
        uriBuilder.setParameter("title", "sample-title-1");
        uriBuilder.setParameter("style", "PARAGRAPH_STYLE");
        uriBuilder.setParameter("content", "['sample-title-1']");
        uriBuilder.setParameter("button_text", "Get Started");
        HttpClient httpClient = HttpClientBuilder.create().build();
        HttpPost httppost = new HttpPost(uriBuilder.build());

        File file = new File(IMAGE_PATH);
        ContentBody cbFile = new FileBody(file,
                ContentType.create(MimeTypeUtils.IMAGE_PNG_VALUE));
        byte[] bytes = FileUtils.readFileToByteArray(file);

        MultipartEntityBuilder builder = MultipartEntityBuilder.create();
         builder.addPart("cover_photo", cbFile);
        // builder.addBinaryBody("cover_photo", file);
        // builder.addBinaryBody("cover_photo", file,
        // ContentType.create(MimeTypeUtils.IMAGE_PNG_VALUE),IMAGE_PATH);
        // builder.addBinaryBody("cover_photo", new FileInputStream(file));
        // builder.addBinaryBody("cover_photo", bytes,
        // ContentType.create(MimeTypeUtils.IMAGE_PNG_VALUE),IMAGE_PATH);

        httppost.setEntity(builder.build());
        httppost.addHeader(new BasicHeader("Content-Type",
                ContentType.MULTIPART_FORM_DATA.getMimeType()));
        System.out.println("executing request " + httppost.getRequestLine());
        HttpResponse response = httpClient.execute(httppost);
        HttpEntity resEntity = response.getEntity();

        System.out.println(response.getStatusLine());
        if (resEntity != null) {
            System.out.println(EntityUtils.toString(resEntity));
        }

根据我在 https://business.facebook.com 的 UI 中的观察。它的第一个上传图片并在 cover_photo_id.

中传递 id

已将未发布的照片上传到 page/photos 并在 context_card 的 cover_photo_id 中传递了生成的 ID。并且有效。

在 facebook 营销 api leadgen_context_cards 边缘不接受 cover_photo

In facebook marketing api leadgen_context_cards edge is not accepting cover_photo
