上传图像二进制 - 使用imageshack api

本文介绍了上传图像二进制 - 使用imageshack api的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

将一个主题从Google群组移到这里，这样可以帮助某个人询问。



imageshack api：



最后的http reqeust正在返回json：

  {success：true，process_time：325，result：{max_filesize：5242880，space_limit：52428800 ，space_used：0，space_left：52428800，passed：0，failed：0，total：0，images：[]}}

这并不好，因为它没有上传：（$ / b
$ b

image object。
，因为这是在imageshack api上的上传图片部分所说的：

请帮忙：（$ / b>

代码 

  var blobUrl; 
 var makeBlob = function（）{
 bigcanvas.toBlob（function（blob ）{
 var reader = ne w window.FileReader（）; 
 reader.readAsBinaryString（blob）; 
 reader.onloadend = function（）{
 blobBinaryString = reader.result; 
 blobUrl = blobBinaryString; 
 Cu.reportError（blobUrl）; 
 uploadBlob（）; 
} 
}）; 
}; 
 
 var uploadedImageUrl; 
 var uploadBlob = function（）{
 HTTP（'POST'，'https://api.imageshack.us/v1/images'，{
 contentType：'application / x-www urlencode（'Stock History'）+'& 
 body：'auth_token ='+ urlencode（auth_token）+'file @ ='+ urlencoded'，
 //'album ='+ urlencode blobUrl，
 onSuccess：function（status，responseXML，responseText，headers，statusText）{

 eval（'var json ='+ responseText）; 
 uploadedImageUrl = json.direct_link;

} 
}）; 
}; 
 
 
 makeBlob（）; // callllll the func


解决方案

此代码上传

可以复制粘贴，但必须更新一些内容：




  • 更新用户名

  • 更新密码

  • b
  • 更新您的API密钥



    • ...

imageshack api: http://api.imageshack.us/

the final http reqeust is returning json:

{"success":true,"process_time":325,"result":{"max_filesize":5242880,"space_limit":52428800,"space_used":0,"space_left":52428800,"passed":0,"failed":0,"total":0,"images":[]}}

which is not good, as it didn't upload :(

it should return an image object. http://api.imageshack.us/#h.ws82a1l6pp9gas this is what the upload image section on the imageshack api says

please help :(

my extension code

解决方案

this code uploads a drawing on a canvas to imageshack

Can copy paste but have to update some things:

  • update username
  • update password
  • uploads drawing from canvas with id "bigcanvas"
  • update your API key

important note for code above

  • should use JSON.parse instead of eval if you want to submit the addon to AMO
  • should also probably change from using window to Services.appShel.hiddenDOMWindow so like new window.FormData(); would become new Services.appShel.hiddenDOMWindow.FormData(); OR var formData = Components.classes["@mozilla.org/files/formdata;1"].createInstance(Components.interfaces.nsIDOMFormData); OR Cu.import('resource://gre/modules/FormData.jsm')
