in this embodiment, the preset activation code may also be entered by the service processing terminal through a scan code.

Step 203, the service processing terminal receives a preset activation code input by a user, and generates a first message according to the preset activation code input by the user;

in this embodiment, the steps specifically include: the business processing terminal carries out abstract operation on the preset activation code to obtain a first abstract value, and generates a first message according to the preset activation code and the first abstract value;

The service processing terminal generating a first signature field value according to each request parameter comprises the following steps:

step a1, the service processing terminal sorts all request parameters according to alphabetical order, wherein a preset activation code is one of the request parameters;

in this embodiment, the request parameter is composed of a parameter identifier and a parameter value thereof;

in this step, the request parameters include: the method comprises the steps of presetting a location parameter, a time zone parameter and an activation code parameter;

for example, the location parameter is local, japan, where local is the location parameter identifier and Japan is the location parameter value;

time zone parameter timezone, p9, wherein timezone is time zone parameter identification, p9 is time zone parameter value;

presetting a product key of an activation code parameter, wherein the product key is a preset activation code mark, and the 5j68dx8v4t4dpo25 is a preset activation code parameter value;

Step a2, the service processing terminal performs form conversion on each request parameter according to a preset format, and connects the request parameters after the form conversion by using a preset symbol to obtain a first character string;

for example, after each request parameter is converted according to the form of parameter identification=parameter value, each parameter after the form conversion is connected by a predetermined symbol & pair, so as to obtain a first character string;

taking the example of each request parameter in the step a1 as an example, the first character string is obtained after conversion according to the step a 2: locale=japan & product key=5j68dx8v4t4dpo25 & timezone=p9;

specifically, in this step, the service processing terminal composes an API key value according to the preset activation code and the token value generated randomly, and adds the API key value to the back of the first string to obtain a second string;

for example, the service processing terminal may, according to the preset activation code 5j68dx8v4t4dpo25 and the randomly generated token value, for example: stg33_shop01FT201900219700101000443990000 forms an API key value of 5j68dx8v4t4dpo25stg33_shop 01FT2019002197001010004439990000, and adds the API key value to the back of the first character string to obtain a second character string; locale=japan & production key=5j68dx8v4t4dpo25 & timezone=p9 & key=5j68dx8v4t4dpo25stg33_sho 01FT2019002197001010004439990000

Step a4, the business processing terminal uses brackets to form a third character string by the second character string, and calculates the third character string to obtain a first signature field value;

for example, the service processing terminal includes the second string locale=japan & product key=5j68dx8v4t4dpo25 & timezone=p9 & key=5j68dx8v4t4dpo25stg33_sho01ft019002197001010439990000 with a bracket to form a third string { locale=japan & product key=5j68dx8v4dpo25 & timezone=p9 & key=5j68dx8v4v4dpo25stg33_sho01ft201900010010004990000 }, and performs an MD5 algorithm on the third string to obtain the first signature field value; sign= "AF72E46a57B8464a954332EFE7FB6D20";

step a4 may also be: the business processing terminal comprises a third character string formed by bracketing the second character string, and carries out operation on the third character string to obtain an operation result, and converts the operation result into capitalization to obtain a first signature field value.

Step 204, the service processing terminal sends the first message to the server;

step 205, the server analyzes the first message to obtain a preset activation code;

in this embodiment, the steps specifically include: the server analyzes the first message to obtain a preset activation code and a first abstract value; in the step, a specific server analyzes a first message to obtain URL data and Json format parameter data, and analyzes the Json format parameter data to obtain a first signature field value and each request parameter; wherein the request parameter comprises a preset activation code;

Step 206, the server verifies the correctness of the first message, judges whether the first message is correct, if yes, executes step 207, if not, reports errors to the service processing terminal, and ends;

in this embodiment, the steps specifically include: the server performs abstract operation on the obtained preset activation code to obtain a second abstract value, judges whether the second abstract value is the same as the first abstract value, if so, the first message is correct, executes step 207, if not, the first message is incorrect, returns error information to the service processing terminal, and ends.

In the step, the algorithm for randomly generating the token value by the server is the same as the algorithm for randomly generating the token value by the service processing terminal;

the process of generating the first signature field verification value by the server is the same as that of generating the first signature field value by the service processing terminal according to each request parameter, and will not be described in detail.

Step 207, the server generates a service processing pointer and a service processing terminal ID (service processing terminal identifier) corresponding to the preset activation code according to the preset activation code, and calculates the service processing pointer and the service processing terminal ID to generate a third abstract value;

step 208, the server generates a response of the first message according to the service processing pointer, the service processing terminal ID and the third abstract value, and sends the response of the first message to the service processing terminal;

the method specifically comprises the following steps: the server generates a corresponding service processing pointer and service processing terminal ID according to the preset activation code, generates a response of the first message according to the service processing pointer and the service processing terminal ID and the state code which is successfully activated, and sends the response of the first message to the service processing terminal.

Step 209, the service processing terminal receives the response of the first message, verifies the correctness of the response of the first message, and stores the service processing pointer and the service processing terminal ID in the response of the first request message when verifying that the response of the first message is correct;

Specifically, the method comprises the following steps: the service processing terminal receives the response of the first message request, analyzes the response of the first message request to obtain a service processing pointer, a service processing terminal ID and a third abstract value, carries out abstract operation on the service processing pointer and the service processing terminal ID to obtain a fourth abstract value, judges whether the third abstract value is the same as the fourth abstract value, stores the service processing pointer and the service processing terminal ID if the third abstract value is the same as the fourth abstract value, and prompts error information by the service processing terminal if the third abstract value is not the same as the fourth abstract value;

for example, the service processing terminal receives the response of the first message request as follows:

{ "meta" { "code": "00", "message": "SUCCESS" }, "data" { "error code": "," error info "," "sign": "25B0890D976A43A8163801B490281DCD", "result" { "activeteTime": "20190829110820", "terminalStatus": "02", "expereTime": "," terminalicode ":" OT04G9h54384uivr "," branchCode ":" OS035610312999"}, and the service processing pointer OS035610312999 and terminal IDOT04G9h54384 uir and the third digest value 25B0890D976A43A8163801B490281DCD are obtained by parsing.

Step 210, the service processing terminal randomly generates a first key pair according to an asymmetric algorithm, saves a private key of the first key pair, and generates a second message according to the service processing pointer, the service processing terminal ID and a public key of the first key pair;
