Email synchronization method and electronic device

An electronic device, comprising:

• one or more processors;
• and
• one or more memories coupled to the one or more processors and storing programming instructions which, when executed by the one or more processors, cause the electronic device to perform operations comprising:
• obtaining an email identifier of an email to be synchronized by an email client installed on the electronic device;
• sending, to a server, a first request comprising the email identifier, wherein the first request is used to request to obtain the email and structure information of a message body of the email, and the structure information is used to represent a data structure of the message body of the email;
• receiving a first response from the server;
• extracting the email and the structure information from the first response;
• determining object identifiers of objects in the message body based on the structure information, wherein the objects in the message body comprise an email body of the email, or the email body of the email and additional information of the email, and wherein the additional information comprises at least one of an embedded resource or an attachment;
• obtaining information of the objects in the message body;
• determining that information of a first object fails to be downloaded, wherein the first object is one of the objects in the message body;
• sending a second request to the server in response to determining that the information of the first object fails to be downloaded, wherein the second request comprises the email identifier and an object identifier of the first object, and the second request is used to request to obtain the information of the first object;
• receiving a second response from the server;
• and
• extracting the information of the first object from the second response.

A non-transitory computer-readable storage medium, comprising computer-readable instructions, wherein the computer-readable instructions, when executed by one or more processors of an electronic device, cause the electronic device to perform operations comprising:

• obtaining an email identifier of an email to be synchronized by an email client installed on the electronic device;
• sending, to a server, a first request comprising the email identifier, wherein the first request is used to request to obtain the email and structure information of a message body of the email, and the structure information is used to represent a data structure of the message body of the email;
• receiving a first response from the server;
• extracting the email and the structure information from the first response;
• determining object identifiers of objects in the message body based on the structure information, wherein the objects in the message body comprise an email body of the email, or the email body of the email and additional information of the email, and wherein the additional information comprises at least one of an embedded resource or an attachment;
• obtaining information of the objects in the message body;
• determining that information of a first object fails to be downloaded, wherein the first object is one of the objects in the message body;
• sending a second request to the server in response to determining that the information of the first object fails to be downloaded, wherein the second request comprises the email identifier and an object identifier of the first object, and the second request is used to request to obtain the information of the first object;
• receiving a second response from the server;
• and
• extracting the information of the first object from the second response.
