使用uniappx h5环境，获取手机照片并上传 报错

signFile的返回值大小写不对，o要像这样大写 @gravitywp

        const signData = await this.signFile(filename);
        const formData = new FormData();
        formData.append('x-oss-signature', signData.xOssSignature);
        formData.append('x-oss-date', signData.xOssDate);
        formData.append('x-oss-signature-version', signData.xOssSignatureVersion);
        formData.append('policy', signData.policy);
        formData.append('key', signData.key);
        formData.append('x-oss-credential', signData.xOssCredential);
        formData.append('x-oss-expires', signData.xOssExpires.toString());
        formData.append('file', blob, filename);

加一，浏览器环境上传文件也有这个问题
