Question

我有Telit调制解调器，我想获取sim电话号码，Telit返回字符串如：

"+CNUM: "","+123456789123456",**145**ok"

Or : "+CNUM: "","+123456789123456",**129**ok"

仅与数字145(International), 129(National)不同。

我想只得到这个号码：+123456789123456，没有＆＃34; + CNUM：＆＃34;＆＃34;，＆＃34;没有，129。

我试过了：

responseBuffer ="+CNUM: "",""+123456789123456"",145";
sscanf(responseBuffer,"%*s %s",phoneNum);   // cut the beginning

如何摆脱字符串的重置，从','到结尾的字符？

Answer 1

感谢@JoachimPileborg，我使用了strtok

responseBuffer ="+CNUM: "",""+123456789123456"",145";
token = strtok(responseBuffer, ",");
if( token != NULL ) 
  token = strtok(NULL, ",");
strcpy(phoneNum,token);

Answer 2

您可以尝试搜索＆＃39; +＆＃39; char并在找到它之后将电话号码存储到字符串指针中。

storePhoneNumber(const char* input, char* dest){
//loop over the input
//look for '+' char
//when found start to store numbers on by one
// put it in to the dest
}

从c中的长字符串获取电话号码作为字符串
