Preparations for Using the SDK

Download the SDK and import it to a local development tool. For details, see Preparation.

Set parameters such as appKey, appSecret, method, and url.

**Table 1** Parameters
Type	Description	Example
Path parameter	The path parameter is part of the URL. Use it to replace the parameter in {} in the URL.	Parameter: param = xxx Original URL: http://Domain name/p1/{param}/p2 Actual URL: http://Domain name/p1/xxx/p2
Query parameter	The query parameter is a supplementary part of the URL.	Parameter: param = xxx Parameter 2: param2 = xxx2 Example 1: Add the query parameter to a method (use the SDK of each language as an example). Example: request.addQueryStringParam("param"," xxx"); Example 2: Add a question mark (?) and the parameter to the end of the URL. If there are multiple parameters, separate them with ampersands (&). Original URL: http://Domain name/p1 Actual URL: http://Domain name/p1?param=xxx&param2=xxx2
Header parameter	The header parameter is part of the request header. The parameter name is case insensitive.	Parameter: param = xxx Add a header parameter to a method or add a header parameter when constructing a request (subject to the SDK of each language). Example: request.addHeader("param"," xxx");
Body parameter	The request body parameter is a JSON string in the SDK. This parameter is unavailable in earlier versions.	"{}"

Modify the SDK and obtain the signature parameter Authorization in the request header after the request is signed. In addition, add the x-Authorization parameter with the same value as Authorization. For details about how to obtain the Authorization parameter and add the x-Authorization parameter, see Preparation.
