1. Signature
1.1 Signature Rules
The signature uses the SHA1WithRSA algorithm. The secretKey serves as the key for SHA1WithRSA, and the parameters in param
+ timestamp
serve as the operating objects for SHA1WithRSA. The output obtained is the signature.
Step 1: Retrieve the request parameters in the body, sort the parameters alphabetically, and form a string.
The sorting method "alphabetical order" means sorting from smallest to largest alphabetically, comparing the first letter first, if the same, compare the second letter, and so on.
Remove all double quotes, whether they are from field names or field values.
No spaces in between.
If the field is
null
, it is not included in the signature.
Step 2: Retrieve the
timestamp
parameter from the request header and append it to the result of Step 1.Step 3: Use the secretKey to perform SHA1WithRSA on the result from Step 2 to generate the signature.
1.2 Signature Example
Request Parameters:
{"companyId":1,"lang":"zh-CN","customerNo":"86001308"}
Calculate Signature:
Step 1: Retrieve the request parameters in the body and sort them alphabetically to form the following string: {“companyId”:1,”customerNo”:”86001308”,”lang”:”zh-CN”}
Step 2: Retrieve the
timestamp
parameter from the request header and append it to the result of Step 1, as follows: {companyId:1,customerNo:86001308,lang:zh-CN}1650361143685Step 3: Use the secretKey to perform SHA1WithRSA on the result from Step 2, the result is: Dihl6oOt5UkaHo9sEouquP3EqbukLX2dAOoKTSGicYryTvH1m9r6vtSLHGutZn7u34/06gjhdpbXRFPdjb51GVHvG75qWXZ1P/boL89xtuja6eTEy9q/aS8R270Q1A+m/MOTxdiifCy0IByrSpCs4VJKaj2d8jlJo2GHznsH+q0=
