用了七牛自己生成uptoken的工具，不加returnBody不报错，加了官网的returnBody格式的上传凭证就报错无语了_问答_ThinkSAAS

这是已经JSON.stringify过的，不加returnBody的凭证
var putPolicy = '{'+
'"saveKey":"$(etag)$(ext)",'+
'"scope":"' + minxing.qiniu.scope + '",'+
'"deadline":' + minxing.qiniu.deadline()+','+
'"mimeLimit":"image/image/png"}';
加密后的uptoken完全没问题
这是加了returnBody（还是官网自己写的样例），妈的已上传就 invalid put policy encoding
var putPolicy = '{'+
'"saveKey":"$(etag)$(ext)",'+
'"scope":"' + minxing.qiniu.scope + '",'+
'"returnBody":"{"key": $(key), "hash": $(etag), "w": $(imageInfo.width), "h": $(imageInfo.height)}",'+
'"deadline":' + minxing.qiniu.deadline()+','+
'"mimeLimit":"image/image/png"}';
我就服了。。。求大神指点下，我把returnBody换了各种方式均报错
1 '"returnBody":{"key": $(key), "hash": $(etag), "w": $(imageInfo.width), "h": $(imageInfo.height)},'+
2 '"returnBody":{"key": "$(key)", "hash": "$(etag)", "w": "$(imageInfo.width)", "h": "$(imageInfo.height)"},'+
都不行。。。
1 var putPolicy = '{"saveKey":"$(etag)$(ext)","scope":"' + minxing.qiniu.scope + '","deadline":' + minxing.qiniu.deadline()+',"mimeLimit":"image/image/png","returnBody":{"key":$(key)}}';
2 var putPolicy = '{"saveKey":"$(etag)$(ext)","scope":"' + minxing.qiniu.scope + '","deadline":' + minxing.qiniu.deadline()+',"mimeLimit":"image/image/png","returnBody":{"key":"$(key)"}}';
3 var putPolicy = '{"saveKey":"$(etag)$(ext)","scope":"' + minxing.qiniu.scope + '","deadline":' + minxing.qiniu.deadline()+',"mimeLimit":"image/image/png","returnBody":"{"key":$(key)}"}';
4 3 var putPolicy = '{"saveKey":"$(etag)$(ext)","scope":"' + minxing.qiniu.scope + '","deadline":' + minxing.qiniu.deadline()+',"mimeLimit":"image/image/png","returnBody":"{"key":"$(key)"}"}';
你参考下面博客，第三条returnbody参数，你拷贝到你的程序试试，不可以的话你去七牛页面提交工单吧
