    COS Request Tool

      Feature Overview

      The COS request tool is a web-based debugging tool provided by COS. It is integrated on the TencentCloud API 3.0 Explorer platform for API debugging.
      Note:
      Requests sent by the COS request tool will be sent to the real COS server. As all operations are real, be careful when performing operations such as DELETE.
      The COS request tool supports XML APIs but not JSON APIs.
      JSON APIs were provided by COS for you to access COS before XML APIs were released. Both types of APIs have the same underlying architecture where data is interconnected; however, they are incompatible with each other.
      XML APIs have a richer set of features and strengths over JSON APIs. We strongly recommend you upgrade to XML APIs for COS.

      Directions

      Select the Cloud Object Storage product, select the required API, enter parameters for the API, and click Send Request to get the corresponding response.
      The COS request tool page shows the sections of product, API, parameter, and result from left to right. You can perform operations in different sections and send the request in the result section to get the response and process parameters.
      
      The detailed steps to use the COS request tool are as shown below:
      1. Select the COS product.
      Click Cloud Object Storage in the product section on the far left, and then you can see COS APIs in the API section.
      Note:
      The COS request tool is integrated on the TencentCloud API 3.0 platform that provides API debugging tools for many Tencent Cloud products. You can also select other products to debug their APIs as needed.
      2. Select the API to be debugged.
      You can select the API for debugging as needed. Three types of COS APIs are shown in the API section: service APIs, bucket APIs, and object APIs.
      Take GET Service as an example for service APIs. This API can list the information of all buckets under your account. Your API key is required. To get the bucket information of your account in a specified region, select the corresponding region in the parameter section. For more information on this API, see GET Service (List Buckets).
      Bucket APIs are used to manipulate buckets, such as PUT Bucket lifecycle. For more information, see Bucket APIs.
      Object APIs are used to manipulate objects, such as PUT Object. For more information, see Object APIs.
      3. Enter parameters for the API.
      The parameter section lists the corresponding parameters for the selected API. For more information on the parameters of COS APIs, see API Documentation.
      API key is a required parameter for API calling. When using an API to manipulate resources such as buckets or objects, you need to enter your API key to authorize the API request, which can be obtained on the Manage API Key page in the CAM console.
      Note:
      For each API, the COS request tool displays a red asterisk behind each required parameter. You can also select Only Required Parameters to view required parameters only in the parameter section.
      4. Send a request and view the response.
      After selecting an API and entering parameters, click Send Request on the Online Call tab. Your request will be sent to the server, and the server will manipulate your buckets or objects accordingly.
      Note:
      Requests sent by the COS request tool will be sent to the real COS server. As all operations are real, be careful when performing operations such as DELETE.
      After the request is sent, the returned result and the request parameters will be displayed in the result section. The Request Parameters part lists your HTTP request body; the Response Result part lists the response body of the request; the Signature Process part lists the signature involved in the request and its generation process; and the Curl part lists the statement called by Curl.
      Sample
      For example, a GET Object request is sent to get a file named 0001.txt as shown below. The Request Parameters part lists the corresponding parameters of the request.
      GET https://bucketname-appid.cos.ap-region.myqcloud.com/0001.txt
      Host: bucketname-appid.cos.ap-region.myqcloud.com
      Authorization: q-sign-algorithm=sha1&q-ak=AKIDwqaGoCIWIG4hDWdJUTL5e3hn04xi****&q-sign-time=1543398166;1543405366&q-key-time=1543398166;1543405366&q-header-list=host&q-url-param-list=&q-signature=f50ddd3e0b54a92df9d4efe2d0c3734a8c90****
      The first line shows your HTTP Verb and the link to be accessed; the second line shows the domain name to be accessed; and the last line shows the signature information of the request. For requests of the PUT type, request headers are complicated, but there are some common request headers. For more information, see Common Request Headers.
      The Signature Process part shows the signature involved in this request and its generation process. For more information on signature algorithms, see Request Signature. If you need to generate and debug request signatures, we recommend you use the COS signature tool.
      The response result returned by COS is as follows:
      200 OK
      content-type: text/plain
      content-length: 6
      connection: close
      accept-ranges: bytes

      hello!
      The 200 OK in the first line is the status code returned for the request. If the request fails, the corresponding error code will be returned. For more information, see Error Codes. Other lines are response headers, which vary by API, but there are some common response headers. For more information, see Common Response Headers.

      Notes

      After you click Send Request to send the request with its required parameters entered to the COS server, COS will perform the corresponding operation on your buckets or objects. The operation cannot be undone or reverted; therefore, proceed with caution.
