我只是想通过 Javascript SDK 将文件从计算机上传到 facebook，下面是我编写的用于在 facebook 上上传图像的代码，我有 Facebook javascript SDK 以及用于服务器端脚本的 PHP语言处理多部分表单数据以上传图像，但我完全不知道如何将图像作为 javascript Facebook SDK 的参数传递

	<script>
         // Wait until the DOM has loaded before querying the document

           var messageToPost;
		   $(document).ready(function(){

			          	var  isLoaded=false;
	  window.fbAsyncInit = function() {
        FB.init({
          appId      : '455772327890425',
          xfbml      : true,
          version    : 'v2.1'
        });
		
		isLoaded=true;
      };
	  
function checkIfLoaded() {
    if(isLoaded) console.log("LOADED!");
    else console.log("NOT YET!");

    return false;
  }
		
      (function(d, s, id){
         var js, fjs = d.getElementsByTagName(s)[0];
         if (d.getElementById(id)) {return;}
         js = d.createElement(s); js.id = id;
         js.src = "//connect.facebook.net/en_US/sdk.js";
         fjs.parentNode.insertBefore(js, fjs);
       }(document, 'script', 'facebook-jssdk'));
       
	   



			
            
			
			setTimeout(function(){alert('after set time out');login(); },2000);
			
			
			 
           
			
						
			
			function login()
			{
				console.log("login called");
               
               FB.login(function (response)
               {
                   accessToken = response.authResponse.accessToken;
                   console.log("inside real login");
               
                   if (response.authResponse) {
                       //fileUpload();
					  
                	  
					   postFB();
                       //Logout();          
                      //alert("Back to Login");
                	   }
                   
                   else {  alert("Login attempt failed!");}
               } , { scope: 'email,user_photos,photo_upload,publish_actions,publish_stream' });

最佳答案

嗯，我不太确定，但我得到了文档:3 https://developers.facebook.com/docs/graph-api/reference/v2.4/album/photos#publish

您可以直接发送图像字节，或使用 URL 让 Facebook 服务器加载它。 :)

使用js-sdk上传图像字节:

FB.api(
    "/{album-id}/photos",
    "POST",
    {
        "source": "{image-data}"
    },
    function (response) {
      if (response && !response.error) {
        /* handle the result */
      }
    }
);

或者，使用 url 而不是上传图像字节:

FB.api(
    "/{album-id}/photos",
    "POST",
    {
        "url": "{image-url}"
    },
    function (response) {
      if (response && !response.error) {
        /* handle the result */
      }
    }
);
