微信小程序无法上传图片

[sysu-lian]

我想使用七牛云实现小程序的图片上传，我测试了你们提供的demo， 1 参数配置如下： { uploadURL: 'https://up-z2.qbox.me', region: 'SCN', // 现使用华南区 shouldUseQiniuFileName: false, domain: 'oqsxl5bup.bkt.clouddn.com', // 这是我的bucket key: 'customFileName.jpg', uptoken: token // 此时的token由后端服务器实时生成 } 2 调试报错如下： WAService.js:3 thirdScriptError Unexpected token u in JSON at position 0;at pages/index/index didPressChooesImage function;at api uploadFile success callback function SyntaxError: Unexpected token u in JSON at position 0 at success (http://1953992292.appservice.open.weixin.qq.com/utils/qiniuUploader.js:101:31) at Object.success (http://1953992292.appservice.open.weixin.qq.com/WAService.js:3:7222) at . (http://1953992292.appservice.open.weixin.qq.com/WAService.js:4:25475) at . (http://1953992292.appservice.open.weixin.qq.com/asdebug.js:1:15029) at http://1953992292.appservice.open.weixin.qq.com/WAService.js:3:7222

3 我仔细核对了你们的sdk使用说明，却并没有找到使用不当地方。在单步调试过程中，发现如下： 微信的 wx.chooseImage函数正确返回了图片的路径filePath wxfile://tmp_1953992292o6zAJs6PljyNcFSJ_PbqvlOfmQZEe98364026356c6875c482c2d282ec664.JPG 但是，执行到你们的函数：qiniuUploader.upload(filePath, (res))，却报错，详见2

4 若是需要我补充调试信息，请尽快告诉我。希望可以得到你们的帮助，谢谢。

It seems that JSON parse failed, I'v updated the error callback at 50f1963b0ba3f7304c5b8d04f33fdcf87c51ea0c, please update the SDK, and check what the error is, or print is directly at qiniuUploader.js:101:31 success callback, I haven't reproduce this error

Thanks for your reply.

1 I have updated the SDK as you advise. But it seems that the problem hasn't been solved. The result as follows.

qiniuUploader.js [sm]:112 parse JSON failed, origin String is: undefined index.js [sm]:93 error: SyntaxError: Unexpected token u in JSON at position 0

2 I think there is something wrong with 'res.data' at qiniuUploader.js:99:5, so I add one code as 'console.log(res)' at qiniuUploader.js: 100:5 , just behind 'var dataString = res.data'. The result as follows.

Object {errMsg: "uploadFile:ok", statusCode: 401}

The error code is 401, Unauthorized ??

3 Looking forward to hear your reply.

抱歉刚用英文回复 401代表 token 出错，比如过期。你可以尝试重新生成一个 token 试试看。 如果依然报错，请检查 token 生成相关代码。 参见：https://segmentfault.com/q/1010000004731359 和 https://segmentfault.com/q/1010000004001375 以及我应该再更新一下报错的内容，现在这个不利于判断错误。。

已确认，是token的key配置参数问题，导致出错。问题已解决，谢谢。
