这是一个HTTP接口测试中经常会碰到的问题，目前的服务器采用的都是UTF-8编码方式，而我们的客户机Windows系统一般默认采用的编码方式是GBK，这正是我们采用录制方式的时候会发现许多中文乱码的原因。
Loadrunner录制的时候可以通过在Virtual User Gen的Tools->Recoding Options -> Advanced -> Support charset -> UTF-8的设置规避（其实也只是部分规避），下面我们讨论在手写测试脚本时如何解决UTF-8转码的问题。
实践一：在脚本中直接采用中文明文进行请求
web_custom_request("web_custom_request",
"URL=http://172.16.4.191/list?id=环球影院",
"Method=GET",
"TargetFrame=",
"Resource=0",
"Referer=",
"Body=",
LAST);
结果：服务端返回404错误，找不到相应的资源id,明显服务端不能正确响应非UTF8编码方式的请求。
实践二：
为解决这个问题，最关键的是要把本地GBK编码的汉字转换成UTF-8编码格式的信息，为此我们引进loadrunner自带的编码函数lr_convert_string_encoding
Converts a string to a different encoding.
C Language
intlr_convert_string_encoding( const char *sourceString, const char *fromEncoding, const char *toEncoding, const char *paramName);
lr_convert_string_encodingconverts a string encoding between the following encodings: System locale, Unicode, and UTF-8.The function saves the result string, including its terminating NULL, in the parameterparamName.
lr_convert_string_encodingis added manually to a script. when needed. It is not recorded.
Possible values for 'fromEncoding' and 'toEncoding' :
LR_ENC_SYSTEM_LOCALE,
LR_ENC_UTF8,
"str" );
web_custom_request("web_custom_request",
"URL=http://172.16.4.191/list?id={str}",
"Method=GET",
"TargetFrame=",
"Resource=0",
"Referer=",
"EncType=text/xml;charset=UTF-8",
"Body=",
LAST);
Action.c(7): GET /list?id=鐜悆褰遍櫌\x00 HTTP/1.1\r\n
Action.c(7): Content-Type: text/xml;charset=UTF-8\r\n
Action.c(7): User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows)\r\n
Action.c(7): Accept-Encoding: gzip, deflate\r\n
Action.c(7): Accept: */*\r\n
Action.c(7): Connection: Keep-Alive\r\n

Action.c(7): \r\n
lr_convert_string_encoding( "环球影院",
LR_ENC_SYSTEM_LOCALE,
LR_ENC_UTF8,
"str" );
strcpy(tmp,lr_eval_string("{str}"));
lr_save_string(tmp,"sorvalue");
web_custom_request("web_custom_request",
"URL=http://172.16.4.191/list?id={sorvalue}",
"Method=GET",
"TargetFrame=",
"Resource=0",
"Referer=",
"Body=",
LAST);
