如何使用Graph API批处理请求上传内联图像？ [英] How to Upload Inline-Images using Graph API Batch Request?
问题描述
我正在使用Graph API Batch Request上传图片，但无法使用内联图片上传，任何人都可以帮我吗？
批量申请文件： https ：//developers.facebook.com/docs/reference/api/batch/
照片批量上传： http://developers.facebook.com/blog/post/493/
照片批量上传博客帖子代码工作正常，但我想从我的服务器上传图片，而不是从我的电脑，例如：/public_html/image/pic.jpg，我不知道我可以做什么。 / p>
编辑：我正在使用PHP SDK 3.0.1
这是我的代码：
<？php
代码已更改，问题已修复，请参阅以下答案

这是从他们的文档：
上传二进制数据
二进制数据可以指定为批量API请求的
的multipart / mime部分的一部分。批量Graph API允许上传多个
二进制项目作为批量调用的一部分。为此，您需要
将所有二进制项目作为multipart / mime附件添加到
请求中，并且需要每个操作使用
attach_files属性引用其二进制项在操作中。 attach_files
属性可以在其
值中以逗号分隔的附件名称列表。
以下示例显示如何上传2张照片在一个批次中
调用：
curl
-F' access_token = ...'\
-F'batch = [{method：POST，\
relative_url：me / photos，\
body ：message =我的猫照片\
attached_files：file1\
}，
{method：POST，\
relative_url ：我/照片，\
body：message =我的狗照片\
attached_files：file2\
}，
]'
-F'file1=@cat.gif'\
-F'file2=@dog.jpg'\

我看到的第一个问题是，批次不应该是URL的一部分，而是部分参数...
请参见下面的原始批次示例：
$ batch = array（）;
$ req = array（
'method'=>'GET'，
'relative_url'=>'/ me'
）;
$ batch [] = json_encode（$ req）;
$ req = array（
'method'=>'GET'，
'relative_url'=>'/ me / albums'
）;
$ batch [] = json_encode（$ req）;
$ params = array（
'batch'=>'['。implode（'，'，$ batch）']'
）;
尝试{
$ info = $ facebook-> api（'/'，'POST'，$ params）;
} catch（FacebookApiException $ e）{
error_log（$ e）;
$ info = null;
}
if（！empty（$ info））{
if（$ info [0] ['code'] =='200'）{
$ user_profile = json_decode （$信息[0] [ '主体']）;
}
if（$ info [1] ['code'] =='200'）{
$ user_albums = json_decode（$ info [1] ['body']）;
}
echo< pre> User Profile：\\\
;
print_r（$ user_profile）;
echo\\\
Albums\\\
;
print_r（$ user_albums）;
echo< pre>;
}
具体说明如何将$ facebook-> api调用格式化...
编辑：
这是一个批量图片上传工作：
$ files = array（
'/data/Pictures/pic1.jpg'，
'/data/Pictures/pic2.jpg'，
'/data/Pictures/pic3.jpg'
）;
//必须将上传支持设置为true
$ facebook-> setFileUploadSupport（true）;
$ batch = array（）;
$ params = array（）;
$ count = 1;
foreach（$ files as $ file）{
$ req = array（
'method'=>'POST'，
'relative_url'=>'/ me /照片'，
'attached_files'=>'文件'$ count
）;
//将此请求添加到批处理中...
$ batch [] = json_encode（$ req）;
//设置要上传的文件的文件路径
$ params ['file'。$ count] ='@'。真实路径（$文件）;
$ count ++;
}
$ params ['batch'] ='['。 implode（'，'，$ batch）。 ];
尝试{
$ upload = $ facebook-> api（'/'，'post'，$ params）;
} catch（FacebookApiException $ e）{
error_log（$ e）;
$ upload = null;
}
//查看结果...
if（！is_null（$ upload））{
echo< pre> 。 print_r（$ upload，1）。 <预> 中;
echo< hr />;
}
刚刚测试，它的作用就像一个魅力...
I'm trying to upload images using Graph API Batch Request, but i'm unable to upload using inline image, can anyone help me please?
Batch Request Docs: https://developers.facebook.com/docs/reference/api/batch/
Photo batch uploads: http://developers.facebook.com/blog/post/493/
Photo batch uploads blog post code works fine, but i want to upload images from my server and not from my pc, Ex: /public_html/image/pic.jpg and i'm not sure how i can do it.
EDIT: I'm using PHP SDK 3.0.1
Here's my code:
<?php
CODE WAS CHANGED AND THE PROBLEM IS FIXED ALREADY, SEE THE ANSWER BELOW
?>
This is from their docs:
Uploading binary data
Binary data can be specified as part of the multipart/mime portion of the batch API request. The batch Graph API allows uploading multiple binary items as part of a batch call. In order to do this, you need to add all the binary items as multipart/mime attachments to your request, and need each operation to reference its binary items using the "attached_files" property in the operation. The "attached_files" property can take a comma separated list of attachment names in its value.
The following example shows how to upload 2 photos in a single batch call:
curl
–F ‘access_token=…’ \
-F ‘batch=[{"method":"POST", \
"relative_url":"me/photos", \
"body":"message=My cat photo" \
"attached_files":"file1" \
},
{"method":"POST", \
"relative_url":"me/photos", \
"body":"message=My dog photo" \
"attached_files":"file2" \
},
]’
-F ‘file1=@cat.gif’ \
-F 'file2=@dog.jpg' \
https://graph.facebook.com
EDIT 2:
The first issue I see is that the Batch should not be part of the URL, but rather part of the params ...
See the crude batch example below:
$batch = array();
$req = array(
'method' => 'GET',
'relative_url' => '/me'
);
$batch[] = json_encode($req);
$req = array(
'method' => 'GET',
'relative_url' => '/me/albums'
);
$batch[] = json_encode($req);
$params = array(
'batch' => '[' . implode(',',$batch) . ']'
);
try {
$info = $facebook->api('/','POST',$params);
} catch(FacebookApiException $e) {
error_log($e);
$info = null;
}
if(!empty($info)){
if($info[0]['code'] == '200'){
$user_profile = json_decode($info[0]['body']);
}
if($info[1]['code'] == '200'){
$user_albums = json_decode($info[1]['body']);
}
echo "<pre>User Profile:\n";
print_r($user_profile);
echo "\nAlbums\n";
print_r($user_albums);
echo "<pre>";
}
Notice specifically how the $facebook->api call is formatted ...
EDIT:
Here is a working batch picture upload:
$files = array(
'/data/Pictures/pic1.jpg',
'/data/Pictures/pic2.jpg',
'/data/Pictures/pic3.jpg'
);
//Must set upload support to true
$facebook->setFileUploadSupport(true);
$batch = array();
$params = array();
$count = 1;
foreach($files as $file){
$req = array(
'method' => 'POST',
'relative_url' => '/me/photos',
'attached_files' => 'file' . $count
);
//add this request to the batch ...
$batch[] = json_encode($req);
//set the filepath for the file to be uploaded
$params['file'.$count] = '@' . realpath($file);
$count++;
}
$params['batch'] = '[' . implode(',',$batch) . ']';
try{
$upload = $facebook->api('/','post',$params);
} catch(FacebookApiException $e) {
error_log($e);
$upload = null;
}
//View the results ...
if(!is_null($upload)){
echo "<pre>" . print_r($upload,1) . "<pre>";
echo "<hr />";
}
Just tested and it works like a charm ...
