oss：获取签名后直传。 使用postman发送第一次请求获取到policy等信息 使用postman发送第二次请求将policy等信息以及本地文件上传至oss 首先我测试了简单上传，accesskey和密码都是正确的，可以上传到oss postman报以下错误： SignatureDoesNotMatch The request signature we calculated does not match the signature you provided. Check your key and signing method. 638DC9AC998B3E363407030E gulimall-zhangsujuan.oss-cn-beijing.aliyuncs.com LTAI5tHbftbCiYrWrsDyiGgB '4574dWM1jSfUKwUL88cH8onNGU4= eyJleHBpcmF0aW9uIjoiMjAyMi0xMi0wNVQxMDoyNDozOC40OTFaIiwiY29uZGl0aW9ucyI6W1siY29udGVudC1sZW5ndGgtcmFuZ2UiLDAsMTA0ODU3NjAwMF0sWyJzdGFydHMtd2l0aCIsIiRrZXkiLCIyMDIyLTEyLTA1LyJdXX0= 65 79 4A 6C 65 48 42 70 63 6D 46 30 61 57 39 75 49 6A 6F 69 4D 6A 41 79 4D 69 30 78 4D 69 30 77 4E 56 51 78 4D 44 6F 79 4E 44 6F 7A 4F 43 34 30 4F 54 46 61 49 69 77 69 59 32 39 75 5A 47 6C 30 61 57 39 75 63 79 49 36 57 31 73 69 59 32 39 75 64 47 56 75 64 43 31 73 5A 57 35 6E 64 47 67 74 63 6D 46 75 5A 32 55 69 4C 44 41 73 4D 54 41 30 4F 44 55 33 4E 6A 41 77 4D 46 30 73 57 79 4A 7A 64 47 46 79 64 48 4D 74 64 32 6C 30 61 43 49 73 49 69 52 72 5A 58 6B 69 4C 43 49 79 4D 44 49 79 4C 54 45 79 4C 54 41 31 4C 79 4A 64 58 58 30 3D
