调用GetWithParams出错：Status Code: 403 Code: SignatureDoesNotMatch Message: The request signature we calculated does not match the signature you provided. Check your key and signing method.

你好，感谢你贡献的第三方库，有个问题请教一下。

在获取image object信息时，在调用func (b *Bucket) GetWithParams(path string, params url.Values) (data []byte, err error)方法时，不幸的是出错时，出错误信息如下：Aliyun API Error: RequestId: 5AB3BEB300261B4583E490A5 Status Code: 403 Code: SignatureDoesNotMatch Message: The request signature we calculated does not match the signature you provided. Check your key and signing method.

但是调用func (b *Bucket) Info() (BucketInfo, error)就没有出错

调用代码, 结果出错，但是类库打印的GET URL地址是可以访问，并获取到图片的信息

func GetWithParams(destBucket string, path string, params url.Values) ([]byte, error) {
	client := NewClient()
	bucket := client.Bucket(destBucket)
	return bucket.GetWithParams(path, params)
}

调用代码, 结果正确:

func GetBucketInfo(destBucket string) (oss.BucketInfo, error) {
	client := NewClient()
	bucket := client.Bucket(destBucket)
	return bucket.Info()
}

client secure 设置为false也是出错

func NewClient() *oss.Client {
	return oss.NewOSSClient(oss.Beijing, false, accessKeyId, accessKeySecret, true)
}

期待你的回复，十分感谢！

能给个例子吗？多谢

错误的用例，我们复现一下

没办法提供你accessKeyId与accesskeySecret，不好意思

func test() {
	//oss中的图片地址
	// ossImgURL := "https://f.meishi.51baibao.com/youpin/test/000dd599-33b9-11e7-a0d7-00163e30b7a8.png"
	destBucket := "meishi-oss"
	dir := "youpin/test/"
	filename := "000dd599-33b9-11e7-a0d7-00163e30b7a8.png"
	path := fmt.Sprintf("%s%s", dir, filename)

	v := url.Values{}
	v.Add("x-oss-process", "image/info")

        //没办法提供accessKeyId, accesskeySecret, 权限太大
	accessKeyId := "aaaa"
	accesskeySecret := "bbbb"
	client := oss.NewOSSClient(oss.Beijing, false, accessKeyId, accesskeySecret, true)
	bucket := client.Bucket(destBucket)
	data, err := bucket.GetWithParams(path, v)

	//lib print
	//GET https://meishi-oss.oss-cn-beijing.aliyuncs.com/youpin/test/000dd599-33b9-11e7-a0d7-00163e30b7a8.png?x-oss-process=image%2Finfo ...
	if err != nil {
		panic(err)
	}

	log.Println("data: ", string(data))

}
