loadrunner接口請求後返回中文亂碼入坑

情景：在練習過程中，模擬請求一個接口，在返回中，中文亂碼

代碼如下

	web_reg_save_param("response",
					   "LB={",
					   "RB=}",
					   "Search=All",
					   "Ord=All",
		LAST);
	web_url("Hit the Slopes and Save", 

    "URL=http://api.k780.com:88/?app=life.postcode&appkey=38067&sign=2b8b7baa13bd02f61399f87fd0ae5a0e&postcode=528400", 

    "TargetFrame=Main", 

    "Resource=0", 

    "Mode=HTML", 
    LAST ); 

	// 轉換之前輸出
	lr_output_message("%s",lr_paramarr_random("response"));

	// 手動轉換後輸出
	lr_convert_string_encoding(lr_paramarr_random("response"),"utf-8",NULL,"msg");

	lr_output_message("%s",lr_eval_string("{msg}"));

看下lr_convert_string_encoding 這個函數的用法

int lr_convert_string_encoding( const char *sourceString, const char *fromEncoding, const char *toEncoding, const char *paramName); 

• sourceString The string to convert
• fromEncoding The encoding of the sourceString
• toEncoding The encoding to convert of the string saved in parameter paramName
• paramName The name of the parameter in which the destination string will be saved

lr_convert_string_encoding converts 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 parameter paramName.

Printable characters in the result string are displayed in VuGen and its logs as the actual characters. Non-printable characters are displayed in Hexadecimal. For example:

rc = lr_convert_string_encoding("A", NULL, LR_ENC_UTF8, "stringInUnicode");

The result string displays as A\x00, and not \x41\x00, because the letter A is a printable character.

Add lr_convert_string_encoding manually to a script when needed. It is not recorded.

Possible values for fromEncoding and toEncoding :

Constant	Value
LR_ENC_SYSTEM_LOCALE	NULL
LR_ENC_UTF8	“utf-8”
LR_ENC_UNICODE	“ucs-2”
