[英]How to read a string with cJSON
我正在使用cJSON,但不知何故我无法使用字符串:
void myfile()
{
cJSON* type = NULL;
char text1[]="{\n\"name\": \"Jack (\\\"Bee\\\") Nimble\", \n\"format\": {\"type\": \"rect\", \n\"width\": 1920, \n\"height\": 1080, \n\"interlace\": false,\"frame rate\": 24\n}\n}";
cJSON * root = cJSON_Parse(text);
cJSON * format = cJSON_GetObjectItem(root,"format");
int framerate = cJSON_GetObjectItem(format,"frame rate")->valueint;
type = cJSON_GetObjectItem(format,"type")->valuestring;
char * rendered = cJSON_Print(root);
cJSON_Delete(root);
printf("rate = %d, type = %s \n", framerate, type) ;
}
我只会垃圾。 我也尝试过,但是它甚至没有编译:
char *type[] = cJSON_GetObjectItem(format,"type")->valuestring;
char text[]="{\n\"name\": \"Jack (\\\"Bee\\\") Nimble\", \n\"format\": {\"type\": \"rect\", \n\"width\": 1920, \n\"height\": 1080, \n\"interlace\": false,\"frame rate\": 24\n}\n}";
cJSON * root = cJSON_Parse(text);
cJSON * format = cJSON_GetObjectItem(root,"format");
cJSON * type = cJSON_GetObjectItem(format,"type");
int framerate = cJSON_GetObjectItem(format,"frame rate")->valueint;
char * rendered = cJSON_Print(root);
printf("%s\n", rendered);
printf("rate = %d, type = %s \n", framerate, type->valuestring);
free(rendered);
cJSON_Delete(root);
