      Feature Description

      This API is used to upload an object within 5 GB to a bucket using an HTML form. To call this API, you need to have permission to write to the bucket.
      Note:
      This API requires a signature different from the standard COS request signatures. For more information, see Signature protection and the description of related fields.
      If you upload an object whose name is the same as another object that is already stored in the bucket with versioning disabled, the old object will be overwritten and the response will be returned normally as specified upon successful upload.
      To upload an image, see the PUT Object API examples for data filling.
      

      Versioning

      For a versioning-enabled bucket, COS will automatically generate a unique version ID for the object, and the ID will be returned in the x-cos-version-id response header.
      For a versioning-suspended bucket, COS will always use null as the version ID of the object and will not return the x-cos-version-id response header.

      Request

      Sample request

      POST / HTTP/1.1
      Host: <BucketName-APPID>.cos.<Region>.myqcloud.com
      Date: GMT Date
      Content-Type: multipart/form-data; boundary=Multipart Boundary
      Content-Length: Content Length
      
      
      
      [Multipart Form Data]
      Note:
      Host: <BucketName-APPID>.cos.<Region>.myqcloud.com, where <BucketName-APPID> is the bucket name followed by the APPID, such as examplebucket-1250000000 (see Bucket Overview > Basic Information and Bucket Overview > Bucket Naming Conventions), and <Region> is a COS region (see Regions and Access Endpoints).

      Request form

      The request body of this API is encoded with multipart/form-data. When sending the request with the HTML <form> element, set the value of the enctype attribute to multipart/form-data. After this, use HTML elements (such as <input> and <select>) to add form fields as needed.
      Form fields
      Field
      Description
      Type
      Required
      key
      Object key. If you use the ${filename} wildcard in the object key, the wildcard will be replaced with the name of the object uploaded (see Example 7).
      string
      Yes
      Cache-Control
      Cache directives defined in RFC 2616. It will be stored as object metadata.

      Redirection target URL if the upload succeeds. If this field is set, HTTP status code "303 (Redirect)" and the Location response header will be returned. Location will include the URL specified in this field as well as the bucket, key, and ETag parameters (see Example 8).
      string
      No

      Enum
      No
      x-cos-grant-read
      Grants a user permission to read the object in the format: id="[OwnerUin]" (e.g., id="100000000001"). You can use comma (,) to separate multiple users, for example, id="100000000001",id="100000000002".

      Signature protection

      This API requires signature-related fields to be carried in the request. COS authenticates the messages carried, and if the authentication is passed, COS executes the request. If not, COS returns an error message and discards the request.
      You can generate a signature as follows:

      1. Preparations

      Log in to the CAM console and go to Manage API Key to get the SecretId and SecretKey.

      2. Generate KeyTime

      a. Get the Unix StartTimestamp of the current time. It is the total number of seconds elapsed from January 1, 1970, 00:00:00 UTC till the current time. b. Calculate the Unix EndTimestamp for the signature to expire according to StartTimestamp and the expected validity period of the signature. c. Generate KeyTime by splicing the two timestamps above in StartTimestamp;EndTimestamp format.

      3. Construct a policy

      A policy is a text in JSON format. A typical policy is as follows:
      {
          "expiration": "2019-08-30T09:38:12.414Z",
          "conditions": [
              { "acl": "default" },
              { "bucket": "examplebucket-1250000000" },
              [ "starts-with", "$key", "folder/subfolder/" ],
              [ "starts-with", "$Content-Type", "image/" ],
              [ "starts-with", "$success_action_redirect", "https://my.website/" ],
              [ "eq", "$x-cos-server-side-encryption", "AES256" ],
              { "q-sign-algorithm": "sha1" },
              { "q-ak": "AKIDQjz3ltompVjBni5LitkWHFlFpwkn9U5q" },
              { "q-sign-time": "1567150692;1567157892" }
          ]
      }
      On the Stream Interruption Records page:
      expiration: The policy's expiration time, which is a string in ISO 8601 format.
      conditions: An array of conditions for the policy. The conditions are described below.
      Type
      Description
      Exact Match
      Uses {" key ":" value "} or [" eq "," $ key "," value "], where key is a limited form field and value is a limited value.
      Prefix Match
      Uses [ "starts-with", "$key", "value" ], where key is a limited form field and value is a limited prefix that can be empty.
      Range Match
      Uses [ "content-length-range", minNum, maxNum ] to limit the file size to be within minNum and maxNum.
      Form fields that can be limited are as follows:
      Field
      Description
      Match Type
      Required
      acl
      ACL attribute of the object
      Exact/Prefix
      No
      bucket
      Bucket for upload
      Exact
      No
      key
      Object key. If you use the ${filename} wildcard in the object key during upload, the object key will be processed to the final object key before the policy is verified. Therefore, you should use prefix match in the policy and ${filename} should not appear.
      Exact/Prefix
      No
      content-length-range
      Range of the file length
      Range
      No
      Cache-Control, Content-Type, Content-Disposition, Content-Encoding, Expires
      Headers defined in RFC 2616, which will be returned as response headers when the object is downloaded.

      No
      success_action_redirect
      Redirection target URL when the upload succeeds

      q-sign-algorithm
      Signature hash algorithm. Fixed at sha1
      Exact
      Yes
      q-ak
      SecretId mentioned above
      Exact
      Yes
      q-sign-time
      KeyTime generated above
      Exact
      Yes
      Note:
      Except for bucket, fields that are used for limitation in the policy must be used in the form fields. For example, if { "acl": "default" } is used, acl must be used and set to default in the form.
      For security reasons, we recommend you use all limitable form fields.

      4. Generate SignKey

      Use HMAC-SHA1 with SecretKey as the key and KeyTime as the message to calculate the message digest (hash value, lowercase hexadecimal), that is, the SignKey (e.g., 39acc8c9f34ba5b19bce4e965b370cd3f62d2fba).

      5. Generate StringToSign

      Use SHA1 with the policy text constructed above to calculate the message digest (hash value, lowercase hexadecimal), that is, the StringToSign (e.g., d5d903b8360468bc81c1311f134989bc8c8b5b89).

      6. Generate Signature

      Use HMAC-SHA1 with SignKey (string, not binary) as the key and StringToSign (string, not binary) as the message to calculate the message digest (hash value, lowercase hexadecimal), that is, the Signature (e.g., 7758dc9a832e9d301dca704cacbf9d9f8172fdef).

      7. Attach the signature to the form

      Attach the policy and signature-related information above to the form as described in the following table:
      Parameter
