Quickblox：上传图片 REST API

Question

http://quickblox.com/developers/Content#Upload_a_file

当我从文件创建的响应中发布我的表单（encode=multipart/form-data action=params 字段时......类似于“http://qbprod.s3.amazonaws.com/?AWSAccessKeyId=AKIAIY7KFM23XGXJ7R7A&Policy=eyAiZXhwaXJhdGlvbiI6ICIyMDEyLTA0LTIzVDE0OjIyOjM0WiIsCiAgICAgICJjb25kaXRpb25zIjogWwogICAgICAgIHsiYnVja2V0IjogInFicHJvZCJ9LAogICAgICAgIFsiZXEiLCAiJGtleSIsICIzMGE4YmNkN2M3MTQ0MTdlYjYyYjk1MzUwZDdlMTNiOTAwIl0sCiAgICAgICAgeyJhY2wiOiAiYXV0aGVudGljYXRlZC1yZWFkIn0sCiAgICAgICAgWyJlcSIsICIkQ29udGVudC1UeXBlIiwgImltYWdlL2pwZWciXSwKICAgICAgICB7InN1Y2Nlc3NfYWN0aW9uX3N0YXR1cyI6ICIyMDEifQogICAgICBdCiAgICB9&Signature=eBtgK1jAzsGNcFjpqEGiTLnm008%3D&key=30a8bcd7c714417eb62b95350d7e13b900&Content-Type=image%2Fjpeg&acl=authenticated-read&success_action_status=201”+ Expires 字段。

响应是： ...我们计算的请求签名与您提供的签名不匹配。检查您的密钥和签名方法。 ...

我做错了什么？ 谁能帮我上传？

你应该从这个字符串发出一个 POST 请求：

    POST http://qbprod.s3.amazonaws.com
