<div id="body1588765301379"><div class="section" id="obs_40_0028__section43491717165116"><h4 class="sectiontitle">Scenario</h4><p id="obs_40_0028__p3431154410448">This case describes how to grant other accounts (excluding IAM users under the account) the read permission for an object or a type of objects in an OBS bucket. For details about how to grant permissions to an IAM user, see <a href="obs_40_0027.html">Granting IAM Users Under an Account the Access to a Bucket and Resources in the Bucket</a>.</p>

<div class="section" id="obs_40_0028__section786219432319"><h4 class="sectiontitle">Configuration Precautions</h4><p id="obs_40_0028__p1436151622312">The preset read-only mode of OBS has the following permissions:</p>
|
|
<ul id="obs_40_0028__ul12273198112311"><li id="obs_40_0028__li1327378202314">GetObject: downloading objects</li><li id="obs_40_0028__li127318812235">GetObjectVersion: downloading versioned objects</li></ul>
|
|
<p id="obs_40_0028__p817120327254">After the configuration is complete, you can read (download) specific objects using APIs. However, if you download an object from OBS Console or OBS Browser+, an error is reported indicating that you do not have required permissions.</p>
|
|
<p id="obs_40_0028__p2027615802413">This is because when you log in to OBS Console or OBS Browser+, APIs (such as <strong id="obs_40_0028__b7957153916368">ListAllMyBuckets</strong> and <strong id="obs_40_0028__b13277941123615">ListBucket</strong>) are called to load the bucket list and object list and some other APIs will also be called on other pages, but your permissions do not cover those APIs. In such case, your access is denied or your operation is not allowed.</p>
