The following describes a file processing method, a device, an electronic apparatus, and a storage medium according to an embodiment of the present disclosure with reference to the accompanying drawings.
Fig. 1 is a flowchart of a file processing method according to an embodiment of the present disclosure. As shown in fig. 1, performed by a client, the method comprises the steps of:
s101, acquiring a query request.
The query request comprises a file identifier of the target file to be queried.
Optionally, the client may be a mobile device, a notebook computer, a tablet computer, a Web client, or the like, and may interact with the server to implement functions such as input and display.
Alternatively, the file identifier may include information such as a file name of the target file and content of the target file. The query request is used for acquiring a file to be queried.
In some embodiments, the query request may also include necessary parameter information for the target file, and different target files to be queried may correspond to different necessary parameter information. For example, a cpt report of line C in city B of province A needs to be queried, line C and line B of province A are all necessary parameter information, and the necessary parameter information is added into a query request, so that a more accurate target file can be obtained according to the query request.
In some embodiments, key value pairs ("key=value") may be set to characterize the necessary parameter information, with the parameter name as a key value, each key value uniquely corresponding to one value; and determining which keys are needed according to the necessary parameter information needed by the target file to be queried, and further determining the value corresponding to each key.
S102, sending the query request to the server, and receiving an encrypted character string of the target file returned by the server, wherein the encrypted character string is generated based on the actual first URL address of the target file.
It can be understood that the query request is sent to the server, and the relevant information of the corresponding target file, such as a character string corresponding to the target file, is requested to be obtained from the server according to the query request. Optionally, in order to ensure the security of the target file, the server may encrypt the related information of the target file to obtain a corresponding encrypted string, and after receiving the query request, the server returns the encrypted string of the target file to the client, so as to ensure that the key information in the target file is not revealed.
In some embodiments, the encrypted string may be generated based on a uniform resource locator (Uniform Resource Locator, URL) of the target file, i.e., based on the actual first URL address of the target file. It can be understood that the first URL address may include information such as a name and a key parameter of the target file, and considering that the first URL address may be directly changed, security is poor, so that the encryption processing of related information such as the first URL address and the content of the target file may obtain an encrypted string, which may achieve the purpose of security and confidentiality of basic information of the target file.
Alternatively, encryption processing may be performed using the cryptographic asymmetric encryption algorithm SM2 or the symmetric encryption algorithm SM 4. That is, the related information of the target file returned by the server is an encrypted string encrypted by the SM2 or SM 4.

Further, the encrypted character string may include a file type of the target file, such as txt, excel, word, pdf, JPEG, GIF, PNG or the like; in order to facilitate the processing of the unified format, different field expressions are adopted for different file types, so that the field corresponding to the type can be determined based on the file type of the target file in the encrypted character string.
In some embodiments, a correspondence between each file type and a field may be determined in advance, and after determining the file type in the encrypted string, a field corresponding to the file type may be obtained according to the correspondence, as a target field of the target file.
S104, determining a second URL address which corresponds to the first URL address and is used for removing the key information based on the original character string and the target field.
It can be understood that the original character string includes basic information corresponding to the target file, and the target field reflects the file type corresponding to the target file, so that the original character string can be reconfigured to determine a second URL address of the target file, where key information in the actual first URL address of the target file is removed from the second URL address. That is, the original character string and the target field are processed to obtain the virtual second URL address of the target file, the target file can be located according to the second URL address, and the key information in the first URL address corresponding to the target file is removed from the second URL address, so as to achieve the effect of keeping the key information of the target file secret.
In some embodiments, the original string and the target field may be recoded to obtain the second URL address, or the original string and the target field may be spliced, and the spliced string may be encrypted to obtain the second URL address, which is not limited herein.

S204, inputting the original character string and the target field into a constructor to obtain a class file object.
Alternatively, the constructors may be binary large object (Binary Large Object, blob) constructors, so that class file objects, i.e., blob objects derived from the Blob constructors. It is understood that a class file object refers to a file-like object, and a Blob object is a class file object containing read-only raw data, and is a class file object of immutable raw data.
The Blob constructor may receive two parameters, parameter one is typically a string or binary object, parameter two is a configuration item, and currently there is only one attribute type; the target field in the embodiment of the present disclosure may be determined by the file type, that is, the type of the file, so that the embodiment of the present disclosure inputs the original string and the target field into the Blob building function, and may obtain the corresponding Blob object.
S205, inputting the class file object into the Uniform resource locator creation sentence, and outputting a second URL address.
After the class file object, namely the Blob object is determined according to the original character string and the target field, a second URL address of the target file is determined according to the Blob object, and key information of the target file, such as the name of the target file and necessary parameters, is removed from the second URL address, so that the aim of keeping the target file secret is fulfilled.
Alternatively, the second URL address may be obtained by using a URL creation statement, for example, the Blob Object is input into the window URL/create Object URL () method, which is used to create a URL containing the specified Object, and the method may return a Blob URL through which the specified Object may be accessed, that is, the Blob Object is input into the window URL/create Object URL () method, and the second URL address of the target file may be output, through which the target file may be accessed.
It can be understood that the second URL is a URL address created by the window URL address creation method, which is different from the actual first URL address of the target file, and key information in the first URL address is removed from the second URL address.
In the embodiment of the disclosure, after the original character string and the target field are determined, constructing the Blob object according to the original character string and the target field, wherein the Blob object comprises the basic information of the target file, creating the second URL address according to the Blob object to obtain a new second URL address which can be accessed to the target file, removing the key information in the first URL address from the second URL address, realizing good hiding of the key information of the target file, and improving the access privacy and security of the target file.
