问题 This question already has answers here : JSON and dealing with unexported fields (2 answers) Closed 2 years ago . I am trying to parse a JSON response with the following code: type Token struct { access_token string `json:access_token` token_type string `json:token_type` expires_in int `json:expires_in` } homeURL := "https:/blah.com/oauth2/token" v := url.Values{} v.Set("client_id", "xxx") v.Set("client_secret", "xxx") v.Set("grant_type", "xxx") s := v.Encode() req, err := http.NewRequest(

Generating Structures dynamically at compile time

问题 I have to generate a data structure that contains certain fields only under certain condition. This typically always translates to something like the following struct MyStruct { int alwaysHere; #ifdef WHATEVER bool mightBeHere; #endif char somethingElse; #if SOME_CONSTANT > SOME_VALUE uint8_t alywasHereButDifferentSize; #else uint16_t alywasHereButDifferentSize; #endif ... }; From my point of view this gets easily ugly to look at, and unreadable. Without even talking about the code that

问题 Hello can someone help me find what is causing the problem? For some reason the find_hash function is giving me problems. It should be failing the if(table -> buckets_array[i] != NULL){ and if(table -> buckets_array[i] != '\0'){ but it is not and it going to the next check which gives me a segmentation fault. What can be causing the first 2 if's statement to pass since I initially set it to table -> buckets_array[i] = NULL? Edit: Thanks for wildplasser I came up with a much better solution

loading txt files into matlab structure

问题 I have a txt file below as shown in the attached figure: a 0.15 ne 1e25 density 200 pulse_num 2 Is has n rows, 2 data on each row. The first data is a sting that contains the field name, and the second data contains the value. The two data is separated by a space. How do I load this txt file into a matlab structure? Basically I want something like: whatIwant = struct('a', 0.15, 'ne', 1e25, 'density', 200, 'pulse_num', 2) I only know how to load it to a table (using readtable ), and I can

问题 Now I having another problem with that, after I changed my coding as shown below, it still showing out the error. Inside the coding, there was no any red underline, therefore I can't find out where's the error.

Write dynamically allocated structure to file

问题 Suppose we have following structure: struct Something { int i; }; If I want to write in a file any data of this type(dynamically allocated), I do this: struct Something *object = malloc(sizeof(struct Something)); object->i = 0; // set member some value FILE *file = fopen("output_file", "wb"); fwrite(object, sizeof(struct Something), 1 file); fclose(file); Now, my questions: How we do this with a structure what contains pointers? I tested using same method, it worked fine, data could been read
