Compute signature failed!

在应用刚打开的时候，调用初始化

String stsPath = UrlPath.baseUrl + UrlPath.stsToken;
AliOSSFlutter  alioss = AliOSSFlutter();
alioss.init(stsPath, "http://oss-cn-hangzhou.aliyuncs.com");
//监听初始化
alioss.responseFromInit.listen((data){
    if(data) { 
        logger.i("阿里云oss初始化成功");
    }else{
    logger.i("阿里云oss初始化失败");
    }
});

stsPath是后台提供的一个api接口地址，接口返回值是：

{
    "StatusCode":200,
    "AccessKeyId":"STS.NUYs1PG9rDboZ2t2ixzNp2v6n",
    "AccessKeySecret":"7sZVNpUKeoVKsSLqc3KNpjSJnK2JYUGRfUkH318vYPvq",

}

执行后打印了下面的日志

从日志上面看，初始化已成功：

然后选择图片上传，我封装了下面方法：

  ///oss上传文件
  ///使用：aliossflutter上传
  ///现在存在的bug: https://github.com/jlcool/aliossflutter/issues/27
  /// context flutter的上下文
  /// uid 上传文件所属的uid(一般是登录用户uid)
  /// bucket 上传到oss 的bucket name
  /// type 上传文件的业务类型
  /// key 上传后文件的路径及文件名(即：oss 里面的key)
  /// file 准备上传的文件
  static Future<OssCallBackData> ossUploadFile2(BuildContext context, int uid, String bucket, String type, String key, File file) {
  
      String path = file.path;
      String key = OssHelper.buildOssKey(path, uid);
      AliOSSFlutter  alioss = AliOSSFlutter();
      Map<String, dynamic> ossConfig = getOssConfig(key, type, uid);
      logger.i("上传回调参数：$ossConfig");

      //url签名：
      //type=1 签名私有资源
      //type=0 签名公开的访问URL
      alioss.signUrl(bucket, key);

      //监听url签名
      alioss.responseFromSign.listen((data){
        if(data.success) {
          logger.i("url 签名 ：${data.url}");
        }else{
          logger.i("url 签名失败");
        }
      });
      
      //上传
      //callbackHost    
      //发起回调请求时 Host 头的值，只有在设置了 callbackUrl 时才有效。
      //如果没有配置 callbckHost，则会解析 callbackUrl 中的 url 并将解析出的 host 填充到 callbackHost 中。
      //参考文档：https://help.aliyun.com/document_detail/31989.html?spm=a2c4g.11186623.2.30.6c474c07zQ8Q3w
      alioss.upload(bucket, file.path, key,
        callbackUrl: ossConfig['callbackUrl'],
        callbackBodyType: ossConfig['callbackBodyType'],
        callbackBody: ossConfig['callbackBody'],
        callbackVars: ossConfig['callbackVars']);

      //监听上传
      alioss.responseFromUpload.listen((data) {

        logger.i("data.success：${data.success}");
        logger.i("data.key：${data.key}");
        logger.i("data.msg：${data.msg}");
        logger.i("data.servercallback：${data.servercallback}");

        if(data.success) {
          
            logger.i("上传成功 key: ${data.key} 服务器回调返回值：${data.servercallback}");
          
        }else{
          logger.i("上传失败");
        }

      });

      alioss.responseFromProgress.listen((data){
        if(data.key==key) {
          logger.i("上传进度：${data.getProgress()} ");
        }
      });
  }

执行后，一直在报错，相关的日志如下：

请问我是哪里搞错了？

上面有个可疑的地方，就是“阿里云oss初始化成功”被打印了2次，我又增加一日志看了一下，我使用的没错，是回调里面调用了2次相关的代码和日志，如下：

logger.i("阿里云oss初始化开始");
String stsPath = UrlPath.baseUrl + UrlPath.stsToken;
AliOSSFlutter  alioss = AliOSSFlutter();
alioss.init(stsPath, "http://oss-cn-hangzhou.aliyuncs.com");
//监听初始化
alioss.responseFromInit.listen((data){
  if(data) { 
      logger.i("阿里云oss初始化成功");
  }else{
    logger.i("阿里云oss初始化失败");
  }
});

打印的日志：

今天下午又测试一遍，依然还是不行，真不知道是哪里不对总是报 Compute signature failed!

就一个stsPath https://api4.qqhot.com/sts/token

而且我们线上也一直在用，怎么会错呢？真是奇怪

Jun 21 '20 09:06 gaoyong06

alioss.responseFromInit.listen放到initState里，注意sts返回格式，你们自己用的格式可能和需要的不一致
