androind http 请求 struts2 action 返回 json 数据 例子

将数据序列化为JSON格式，序列化操作完成后务使用Myfree()函数来释放内存 void Josn_format() { //cJSON构造方法 cJSON *root = cJSON_CreateObject(); cJSON_AddNumberToObject(root, "ADC1", Dev_data.ai1); cJSON_AddNumberToObject(root, "ADC2", Dev_data.ai2); cJSON_AddNumberToObject(root, "ADC3", Dev_data.ai3); cJSON_AddNumberToObject(root,"DI1", Dev_data.input[0]); cJSON_AddNumberToObject(root,"DI2", Dev_data.input[1]); cJSON_AddNumberToObject(root,"DI3", Dev_data.input[2]); cJSON_AddNumberToObject(root,"DI4", Dev_data.input[3]); cJSON_AddNumberToObject(root,"DI5", Dev_data.input[4]); cJSON_AddNumberToObject(root,"DI6", Dev_data.input[5]); cJSON_AddNumberToObject(root,"DI7", Dev_data.input[6]); cJSON_AddNumberToObject(root,"DI8", Dev_data.input[7]); cJSON_AddNumberToObject(root,"DI9", Dev_data.input[8]); cJSON_AddNumberToObject(root,"DI10", Dev_data.input[9]); cJSON_AddNumberToObject(root,"DI11", Dev_data.input[10]); cJSON_AddNumberToObject(root,"DI12", Dev_data.input[11]); cJSON_AddNumberToObject(root,"DI13", Dev_data.input[12]); cJSON_AddNumberToObject(root,"DI14", Dev_data.input[13]); cJSON_AddNumberToObject(root,"DI15", Dev_data.input[14]); cJSON_AddNumberToObject(root,"DI16", Dev_data.input[15]); char *s = cJSON_PrintUnformatted(root); int size=strlen(s)+1; memcpy(Dev_data.json_string,s,size); cJSON_Delete(root); myfree(s); }

html页面用json想server发送查询请求，，然后server返回结果，用json接收，dhtml显示数据

这个例子也是在网上找到的，csdn和百度文库都有，但是资料不全，没法运行或者没有解释清楚。现在我总算调试通过，把经验共享给大家。
