AWS lambda函数:在php中直接浏览器上传时不会触发put事件

I've successfully created a lambda function that resizes an image and stores into a bucket in s3(bucket name:cropped). Also this lambda function invokes when a file is uploaded into another bucket(bucket name:source).

When i upload an image through aws console into the source bucket the AWS lambda function is triggered and the cropped image is created in cropped bucket.

But when i try with programmatic file upload ( s3 browser file upload) the lambda function is not triggered(cropped image is not creating in cropped bucket) however the image is successfully uploaded into source bucket.

Browser file upload

<form id="upload" action="//s3-us-west-2.amazonaws.com/lambdacushbu" method="POST" enctype="multipart/form-data">

    <input type="hidden" name="Content-Type" value="multipart/form-data" />
<input type="hidden" name="acl" value="private" />
<input type="hidden" name="success_action_status" value="201" />
<input type="hidden" name="policy" value="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" />

<input type="hidden" name="X-amz-date" value="20170324T054410Z" />

<input type="hidden" name="key" value="${filename}" />
    <input type="file" name="file" id="image">
    <br>
    <input type="submit" value="upload" name="upload">
        <span id="status-text"></span>
        <img src=""  id="cropped-image">
</form>

UPDATE

I've tried with normal file upload method ie user uploads file to my server and then it put into aws s3 bucket. Now its working

So i think there is an issue with direct browser upload

图片转代码服务由CSDN问答提供 功能建议

我已成功创建了一个lambda函数,该函数调整图像大小并存储到s3中的存储桶中(存储桶名称:< 代码>裁剪)。 此外,当文件上传到另一个存储桶(存储桶名称: source )时,此lambda函数会调用。

当我 通过aws控制台将图像上传到 source 存储桶中,触发AWS lambda函数,并在 cropped 存储桶中创建裁剪后的图像。

但是当我尝试使用程序化文件上传(s3浏览器文件上传)时,不会触发lambda函数(裁剪后的图像不会在 cropped 存储桶中创建)但是图像已成功上传到 source < / code> bucket。

浏览器文件上传

 &lt; form id =“upload”action =  “//s3-us-west-2.amazonaws.com/lambdacushbu”method =“POST”enctype =“multipart / form-data”&gt; 
 
&lt; input type =“hidden”name =“Content-” 输入“value =”multipart / form-  data“/&gt; 
&lt; input type =”hidden“name =”acl“value =”private“/&gt; 
&lt; input type =”hidden“name =”success_action_status“value =”201“/&gt; \  n&lt; input type =“hidden”name =“policy”value =“”/&gt; 
&lt; input type =“hidden”name =“X-amz-credential”value =“AKIAJRVEARQ / 20170324 / us-west-2  / s3 / aws4_request“/&gt; 
&lt; input type =”hidden“name =”X-amz-algorithm“value =”AWS4-HMAC-SHA256“/&gt; 
&lt; input type =”hidden“name =”  X-amz-date“value =”20170324T054410Z“/&gt; 
&lt; input type =” 隐藏“name =”X-amz-signature“value =”854ea7ec0c456c03509d22a6de39b045e54b71a779af8d88175717d8b54ccebc“/&gt; 
&lt; input type =”hidden“name =”key“value =”$ {filename}“/&gt; 
&lt;输入类型 =“file”name =“file”id =“image”&gt; 
&lt; br&gt; 
&lt; input type =“submit”value =“upload”name =“upload”&gt; 
&lt; span id  =“status-text”&gt;&lt; / span&gt; 
&lt; img src =“”id =“cropped-image”&gt; 
&lt; / form&gt; 
   
 \  n 

UPDATE

我尝试过普通的文件上传方法,即用户将文件上传到我的服务器,然后将其放入aws s3存储桶。 Now 它的工作

所以我认为直接浏览器上传存在问题

    Finally i resolved the issue for the browser direct uploads the events is POST

    For enabling

    1.Go to s3 console and select the bucket.

    2.Go to properties select Events and add a new event with POST

    Create the event with post and choose your lambda function that you want to invoke and save.
