1.局部变量，仅本函数使用，如下的变量preseluseres：
submit_revisions() { char *preseluser,preseluseres[30]; //定义字符变量preseluser，用来表示预选用户,其中变量preseluseres作为preseluser的跳板，直接引用preseluser，就会成为一个常量 //定义字符串变量preseluseres，字符串长度为30 char *preselusertwo,preselusertwoes[30]; preseluser=lr_paramarr_random("selectusers"); //使用lr_paramarr_random函数随机获取selectusers列表中任意一项作为字符变量preseluser的值 preselusertwo = lr_paramarr_random("selectusers"); //随机获取selectusers列表中任意一项作为字符串变量preselusertwo的值 lr_output_message("preseluser=%s",preseluser); //打印preseluser的值 lr_output_message("preselusertwo=%s",preselusertwo); //打印preselusertwo的值 while(1) { if(preselusertwo==preseluser) { preselusertwo = lr_paramarr_random("selectusers"); //重新随机获取值 lr_output_message("preselusertwo=%s",preselusertwo); //打印preselusertwo的值 } else break; //否则退出循环 } sprintf(preseluseres,"Value=%s",preseluser); //使用sprintf函数，将"Value=%s"作为变量preseluseres的值 lr_output_message("preseluseres=%s",preseluseres); //打印preseluseres的值，验证preseluseres值是否正确，真正运行时可以把此行注释掉 web_submit_data("add", "Action=http://192.168.1.102:8000/reversion/revision/add/", "Method=POST", "EncType=multipart/form-data", "RecContentType=text/html", "Referer=http://192.168.1.102:8000/reversion/revision/add/", "Snapshot=t6.inf", "Mode=HTML", ITEMDATA, "Name=csrfmiddlewaretoken", "Value={addrevisionscsrfmiddlewaretoken}", ENDITEM, "Name=csrfmiddlewaretoken", "Value={addrevisionscsrfmiddlewaretoken}", ENDITEM, "Name=date_created_0", "Value={DateParame}", ENDITEM, "Name=date_created_1", "Value={HourMinParam}", ENDITEM, "Name=user", preseluseres, ENDITEM, //引用preseluseres的值 "Name=comment", "Value=123", ENDITEM, "Name=version_set-TOTAL_FORMS", "Value=0", ENDITEM, "Name=version_set-INITIAL_FORMS", "Value=0", ENDITEM, "Name=version_set-MIN_NUM_FORMS", "Value=0", ENDITEM, "Name=version_set-MAX_NUM_FORMS", "Value=1000", ENDITEM, "Name=version_set-__prefix__-revision", "Value=", ENDITEM, "Name=version_set-__prefix__-object_id", "Value=", ENDITEM, "Name=version_set-__prefix__-content_type", "Value=", ENDITEM, "Name=version_set-__prefix__-db", "Value=", ENDITEM, "Name=version_set-__prefix__-format", "Value=", ENDITEM, "Name=version_set-__prefix__-serialized_data", "Value=", ENDITEM, "Name=version_set-__prefix__-object_repr", "Value=", ENDITEM, "Name=version_set-__prefix__-id", "Value=", ENDITEM, "Name=_save", "Value=", ENDITEM, EXTRARES, "Url=/static/xadmin/vendor/font-awesome/fonts/fontawesome-webfont.eot?", "Referer=http://192.168.1.102:8000/reversion/revision/", ENDITEM, LAST); return 0; }
2.其他地方也需要使用时，如下变量preseluseres，之后其他函数中也可以使用变量preseluseres：
char preseluseres[30]; submit_revisions() { char *preseluser; //定义字符变量preseluser，用来表示预选用户,其中变量preseluseres作为preseluser的跳板，直接引用preseluser，就会成为一个常量 //定义字符串变量preseluseres，字符串长度为30 char *preselusertwo,preselusertwoes[30]; preseluser=lr_paramarr_random("selectusers"); //使用lr_paramarr_random函数随机获取selectusers列表中任意一项作为字符变量preseluser的值 preselusertwo = lr_paramarr_random("selectusers"); //随机获取selectusers列表中任意一项作为字符串变量preselusertwo的值 lr_output_message("preseluser=%s",preseluser); //打印preseluser的值 lr_output_message("preselusertwo=%s",preselusertwo); //打印preselusertwo的值 while(1) { if(preselusertwo==preseluser) { preselusertwo = lr_paramarr_random("selectusers"); //重新随机获取值 lr_output_message("preselusertwo=%s",preselusertwo); //打印preselusertwo的值 } else break; //否则退出循环 } sprintf(preseluseres,"Value=%s",preseluser); //使用sprintf函数，将"Value=%s"作为变量preseluseres的值 lr_output_message("preseluseres=%s",preseluseres); //打印preseluseres的值，验证preseluseres值是否正确，真正运行时可以把此行注释掉 web_submit_data("add", "Action=http://192.168.1.102:8000/reversion/revision/add/", "Method=POST", "EncType=multipart/form-data", "RecContentType=text/html", "Referer=http://192.168.1.102:8000/reversion/revision/add/", "Snapshot=t6.inf", "Mode=HTML", ITEMDATA, "Name=csrfmiddlewaretoken", "Value={addrevisionscsrfmiddlewaretoken}", ENDITEM, "Name=csrfmiddlewaretoken", "Value={addrevisionscsrfmiddlewaretoken}", ENDITEM, "Name=date_created_0", "Value={DateParame}", ENDITEM, "Name=date_created_1", "Value={HourMinParam}", ENDITEM, "Name=user", preseluseres, ENDITEM, //引用preseluseres的值 "Name=comment", "Value=123", ENDITEM, "Name=version_set-TOTAL_FORMS", "Value=0", ENDITEM, "Name=version_set-INITIAL_FORMS", "Value=0", ENDITEM, "Name=version_set-MIN_NUM_FORMS", "Value=0", ENDITEM, "Name=version_set-MAX_NUM_FORMS", "Value=1000", ENDITEM, "Name=version_set-__prefix__-revision", "Value=", ENDITEM, "Name=version_set-__prefix__-object_id", "Value=", ENDITEM, "Name=version_set-__prefix__-content_type", "Value=", ENDITEM, "Name=version_set-__prefix__-db", "Value=", ENDITEM, "Name=version_set-__prefix__-format", "Value=", ENDITEM, "Name=version_set-__prefix__-serialized_data", "Value=", ENDITEM, "Name=version_set-__prefix__-object_repr", "Value=", ENDITEM, "Name=version_set-__prefix__-id", "Value=", ENDITEM, "Name=_save", "Value=", ENDITEM, EXTRARES, "Url=/static/xadmin/vendor/font-awesome/fonts/fontawesome-webfont.eot?", "Referer=http://192.168.1.102:8000/reversion/revision/", ENDITEM, LAST); return 0; }
