Verify the authenticity of the message. Add a filter to the project where the MVC Controller is located, and rewrite the public override void OnActionExecuting(ActionExecutingContext filterContext) method in the filter to create a new data model. Note: When the server receives the message, it is no longer signature but msg_signature. Example of HTTP request message sent by WeChat server to the server POST /cgi-bin/wxpush? msg_signature=477715d11cdb4164915debcba66cb864d751f3e6×tamp=1409659813&nonce=1372623149 HTTP/1.1Host: qy.weixin.qq.com Method rewriting to implement verification of messages and call WeChat Verification method during access, but the parameters need to be slightly modified. Use the newly created data model in the Action method or in Co

The following are some .NET we have summarized... 9. .net’s method of developing WeChat public platform Introduction: The public platform information interface provides developers with a new message processing method. Only after applying to become a developer can you use the development of the public platform Function, here you need to fill in a URL and a Token. These two pieces of information also require you to have your own server (external network server) resources. The Token can be filled in by the developer arbitrarily. The URL is the link address of the interface configuration information. 10. .net WeChat public account development ##Introduction: This article explains how to use .net to develop a WeChat public account and how to operate it.

The char array stores character sequences in C language and is declared as char array_name[size]. The access element is passed through the subscript operator, and the element ends with the null terminator '\0', which represents the end point of the string. The C language provides a variety of string manipulation functions, such as strlen(), strcpy(), strcat() and strcmp().

The usage methods of symbols in C language cover arithmetic, assignment, conditions, logic, bit operators, etc. Arithmetic operators are used for basic mathematical operations, assignment operators are used for assignment and addition, subtraction, multiplication and division assignment, condition operators are used for different operations according to conditions, logical operators are used for logical operations, bit operators are used for bit-level operations, and special constants are used to represent null pointers, end-of-file markers, and non-numeric values.

In C, the char type is used in strings: 1. Store a single character; 2. Use an array to represent a string and end with a null terminator; 3. Operate through a string operation function; 4. Read or output a string from the keyboard.

In C language, special characters are processed through escape sequences, such as: \n represents line breaks. \t means tab character. Use escape sequences or character constants to represent special characters, such as char c = '\n'. Note that the backslash needs to be escaped twice. Different platforms and compilers may have different escape sequences, please consult the documentation.

In C language, char type conversion can be directly converted to another type by: casting: using casting characters. Automatic type conversion: When one type of data can accommodate another type of value, the compiler automatically converts it.

A strategy to avoid errors caused by default in C switch statements: use enums instead of constants, limiting the value of the case statement to a valid member of the enum. Use fallthrough in the last case statement to let the program continue to execute the following code. For switch statements without fallthrough, always add a default statement for error handling or provide default behavior.

The difference between multithreading and asynchronous is that multithreading executes multiple threads at the same time, while asynchronously performs operations without blocking the current thread. Multithreading is used for compute-intensive tasks, while asynchronously is used for user interaction. The advantage of multi-threading is to improve computing performance, while the advantage of asynchronous is to not block UI threads. Choosing multithreading or asynchronous depends on the nature of the task: Computation-intensive tasks use multithreading, tasks that interact with external resources and need to keep UI responsiveness use asynchronous.

There is no built-in sum function in C language, so it needs to be written by yourself. Sum can be achieved by traversing the array and accumulating elements: Loop version: Sum is calculated using for loop and array length. Pointer version: Use pointers to point to array elements, and efficient summing is achieved through self-increment pointers. Dynamically allocate array version: Dynamically allocate arrays and manage memory yourself, ensuring that allocated memory is freed to prevent memory leaks.
