[0047] Embodiments of the present invention provide a method, device and storage medium for detecting the status of a WhatsApp number.

[0048] The embodiments disclosed in the present invention will be described in more detail below with reference to the accompanying drawings. Although certain embodiments disclosed in the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be construed as being limited to the embodiments described herein, which are instead provided for a more thorough and complete understanding of the present invention. It should be understood that the drawings and embodiments disclosed in the present invention are only for exemplary purposes and are not intended to limit the scope of protection disclosed in the present invention.

[0049] In the description of the embodiments disclosed in the present invention, the term "including" and similar terms should be understood as open inclusion, that is, "including but not limited to". The term "based on" should be understood as "based at least in part on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment". The terms "first", "second", etc. may refer to different or the same objects. Other explicit and implicit definitions may also be included below.

[0050] For ease of understanding, the specific process of the embodiment of the present invention is described below. Figure 1 , an embodiment of the method for detecting the status of a WhatsApp number in an embodiment of the present invention includes:

[0051] 101. When receiving a service request sent by a client, extract a telephone number to be detected from the service request;

[0052] Specifically, when receiving a service request sent by a client, data verification is performed to ensure that the request contains a valid phone number, for example, verifying whether the phone number meets the format requirements.

[0053] Optionally, the service request includes multiple telephone numbers to be detected, and all telephone numbers to be detected are extracted at one time through a loop or batch processing method, and are subsequently processed one by one.

[0054] Optionally, after extracting the telephone number, data cleaning operations are performed on the number, such as removing prefixes and formatting the number, to ensure accuracy and consistency of subsequent processing.

[0055] Optionally, during the process of extracting the telephone number to be detected, exception handling is performed, such as returning an error message or skipping the request.

[0056] Specifically, Figure 2 This is a schematic diagram of a specific embodiment of step 103 of the method for detecting the status of a WhatsApp number in an embodiment of the present invention. Step 103 also includes the following specific implementation methods:

[0057] 1031. When receiving a service request sent by a client, determine the number of telephone numbers to be processed carried in the service request;

[0058] 1032. When the number is only one, use the to-be-processed phone number as the to-be-detected phone number;

[0059] 1033. When there are multiple numbers, select target phone numbers from the to-be-processed phone numbers in sequence as the to-be-detected phone numbers.

[0060] In steps 1031-1033, by determining the number of telephone numbers to be processed, different processing methods can be adopted according to different situations. When there are multiple numbers, each telephone number is processed in turn, so that the system can handle a large number of telephone number detection requests.

[0061] 102. When the telephone number to be detected is obtained, a preset Client instance is obtained;

[0062] Specifically, a preset wppcontent.js library is started; and a preset Client instance is obtained in the wppcontent.js library.

[0063] The wppcontent.js library is a preset JavaScript library that contains some functions or methods for WhatsApp number status detection. The specific content may include functions such as interacting with the WhatsApp platform, sending detection requests, receiving and parsing number information, etc.

[0064] The Client instance is an instance of an object preset in the wppcontent.js library, which encapsulates the specific method of number detection. The Client instance includes methods for sending detection requests to the WhatsApp platform, as well as methods for processing returned number information, determining number status, and recording detection results.

[0065] Optionally, detect whether Node.js is installed; if the Node.js is installed, initialize the npm project; according to the npm project, install the wppcontent.js library; generate a Client instance in the wppcontent.js library.

[0066] Node.js is a JavaScript runtime environment based on the Chrome V8 engine, which is used to run JavaScript code on the server side. It allows developers to write server-side code in JavaScript, rather than just running it in the browser. Node.js provides a rich library and modules that can easily build high-performance network applications. Detecting whether Node.js is installed may be to ensure that JavaScript code can be executed on the server side.

[0067] Among them, npm is a package management tool for Node.js, which is used to install, share and manage JavaScript modules. With npm, developers can easily install third-party modules, manage project dependencies, and share modules they have written. An "npm project" usually refers to a JavaScript project based on Node.js, in which npm is used to manage the various modules and dependencies required for the project. The steps to initialize an npm project usually include creating a package.json file to describe project information and dependencies so that npm can correctly manage and install these dependencies.

[0068] Optionally, when the phone number to be detected is obtained, an authorization QR code of the Client instance is generated; the authorization QR code is output; when an authorization request in response to the authorization QR code is detected, a preset Client instance is obtained. Authorization is performed by scanning the QR code, thereby ensuring the legitimacy verification of the WhatsApp account.

[0069] Optionally, call the Session service in the Client instance to send a detection request to the WhatsApp platform. For example, first obtain the npm wppcontent.js library, then start the node service to run the js for reviewing messages, start the Client in the wppcontent.js library to initialize the Session service, and save it locally on the user. Use the Client to initialize the QR code, allowing e-commerce companies to use the mobile phone's WhatsApp to scan the code for authorization. The Client listens to the ready service to prompt that the initialization is successful, and uses client.checkNumberStatus to detect whether the number is a valid WhatsApp number. Among them, the Session service refers to the service used to manage user session information, and is used for message review and number detection on the WhatsApp platform.

[0070] 103. According to the number detection algorithm in the Client instance, the number to be detected is used as a parameter to send a detection request to the WhatsApp platform, wherein the WhatsApp platform responds to the detection request and returns the number information of the phone number to be detected;

[0071] Specifically, the phone number to be tested is used as a parameter to construct request data and prepare to send a test request to the WhatsApp platform; a connection with the WhatsApp platform is established; the constructed request data is sent to the WhatsApp platform; response data from the WhatsApp platform is monitored; data returned by the WhatsApp platform is received and parsed; the data returned by the WhatsApp platform is parsed to extract the required number information; the obtained number information is processed and stored, such as number status, registration status, etc.; the obtained number information is fed back to the user, which can be displayed on the interface or notified to the user by other means; after completing the data interaction, the connection with the WhatsApp platform is closed to release resources.

[0072] 104. When the number information is received, judging whether the number to be monitored is a valid WhatsApp number according to the number status in the number information, and obtaining a detection result record;

[0073] Specifically, the number information includes:

[0074] Number status: indicates the current status of the phone number to be detected, such as valid, invalid, unregistered, etc.

[0075] Registration time: If the number status is valid, WhatsApp will provide the time when the number was registered with WhatsApp.

[0076] Last active time: indicates the last time the number was active on WhatsApp, such as the last login, message sent, etc.

[0077] Number of bound devices: indicates the number of WhatsApp devices bound to the number, which can help you understand the multi-device usage of the number.

[0078] User information: basic information about the user of this number, such as nickname, avatar, etc.

[0079] Privacy settings: Indicates the privacy settings of the number, such as whether personal information is disclosed to the public.

[0080] Use the method provided by the wppcontent.js library to detect the status of the number and determine whether it is a valid WhatsApp number. If the detection result is a valid WhatsApp number, the detection result is recorded as "valid"; otherwise, it is recorded as "invalid". Output the detection result record, and the detection result is recorded as valid or invalid.

[0081] Specifically, Figure 3 1 is a schematic diagram of a specific embodiment of step 104 of the method for detecting the status of a WhatsApp number in an embodiment of the present invention. Step 104 also includes the following specific implementation methods:

[0082] 1041. When the number information is received, detect specific information of the number status in the number information;

[0083] 1042. If the specific information is valid, the telephone number to be tested is recorded as a valid WhatsApp number as a test result;

[0084] 1043. If the specific information is invalid, the to-be-tested phone number is recorded as an invalid WhatsApp number as a test result;

[0085] 1044. If the specific information is not valid, and the specific information is not invalid, the to-be-detected phone number is recorded as a detection result as being a non-WhatsApp number.

[0086] In steps 1041-1044, three situations are distinguished: valid WhatsApp numbers, invalid WhatsApp numbers, and non-WhatsApp numbers. Numbers in different states are recorded, providing concise and useful information to users.

[0087] 105. Fill the to-be-detected telephone number and the detection result record into a preset table to obtain a number status table;

[0088] Specifically, a preset number status table is created, including a column of telephone numbers to be tested and a column of test result records;

[0089] When the number information is received and it is determined whether the number to be monitored is a valid WhatsApp number, the phone number to be tested and the test result record are filled into a row of the preset table.

[0090] If the same phone number to be tested already exists in the table, update the test result record corresponding to the row;

[0091] If the phone number does not exist in the table, a new row is added to fill in the phone number and test result record.

[0092] The filling process can traverse each row in the table and compare the phone number to be tested with the phone numbers already in the table. If a matching phone number is found, the test result record of the row is updated. If no matching phone number is found, a new row is added to the end of the table, filling in the phone number to be tested and the test result record.

[0093] The resulting number status table will contain all the phone numbers to be tested and their corresponding test result records, which is used to record and track the status information of each number.

[0094] Specifically, Figure 41 is a schematic diagram of a specific embodiment of step 105 of the method for detecting the status of a WhatsApp number in an embodiment of the present invention. Step 105 also includes the following specific implementation methods:

[0095] 1051. Determine whether the number information carries the most recent active time and basic user information;

[0096] 1052. If the number information carries the most recent active time and the user basic information, a generation operation of a customized push policy is generated according to the most recent active time and the user basic information to obtain policy text information;

[0097] 1053. Fill the policy text information, the telephone number to be detected and the detection result record into a preset table to obtain a number status table.

[0098] Among them, the status detection device of the WhatsApp number will determine whether the number information is accompanied by the most recent active time and the basic information of the user. Basic information includes but is not limited to the user's age, gender, and occupation. If the phone number information contains this data, a personalized push strategy will be generated based on this information. For example, if the user is a young woman, the generated push strategy may contain more information about cosmetics.

[0099] After generating a push strategy, the system will save the strategy in text form. Then, the system will fill these strategy text information, the phone number to be tested and the test result record into a preset table to form a number status table. This helps marketers better understand user behavior habits.

[0100] In steps 107-109, it is determined whether the number information carries the most recent active time and basic user information. A push plan can be formulated for each user based on this information. Customized push strategies can better meet user needs. The generated strategy text information, the phone number to be tested, and the test result records are filled into the preset table. A complete status information file can be established for each number, including test results, customized push strategies, etc. This is helpful for subsequent business decisions.

[0101] 106. Respond to the service request according to the number status table.

[0102] Specifically, when the number status table is obtained, it is rendered and displayed to respond to the service request.

[0103] In the embodiment of the present invention, by extracting the phone number to be detected and sending a detection request, there is no need to manually enter the mobile phone number for verification on the WhatsApp official website, which saves time; by obtaining a preset Client instance and a number detection algorithm, an automated number detection process can be implemented, which improves efficiency and is suitable for big data phone number testing. A large number of business requests and number information can be processed, thereby meeting the needs of rapid promotion of e-commerce companies; the phone number to be detected and the detection result records are filled into a preset table for subsequent analysis and use; through the number detection algorithm of this embodiment, fast, accurate, and automated number detection is implemented, and the detection efficiency of WhatsApp numbers is improved.
