记录一些踩坑笔记

1.http.post包有时候会验证https证书的有效性，需要加上一下代码进行跳过https证书的验证.以及跟随302跳转

错误:x509: cannot validate certificate for xxx:xxx:xxx:xxx because it doesn't contain any IP SANs

func Test(url string) {
	tr := &http.Transport{
		TLSClientConfig: &tls.Config{InsecureSkipVerify: true},
	}
	c := &http.Client{
		Transport: tr,
		Timeout:   5 * time.Second,
		CheckRedirect: func(req *http.Request, via []*http.Request) error {
			return http.ErrUseLastResponse
		},
	}
	reqest, err := c.Get(url)
	if err != nil {
		return
	}

	defer reqest.Body.Close()
	if err != nil {
		fmt.Println("出错了！")
		return
	}

	body, err := ioutil.ReadAll(reqest.Body)
	//fmt.Println(string(body))
	pageStr := string(body)
	if reqest.Status == "302 Found" {
		log.Println("有302重定向，重定向内容.", nurl)
	}
	
}

2.golang设置图标与uac权限

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
<assemblyIdentity
    version="1.0.0.0"
    processorArchitecture="x86"
    name="controls"
    type="win32"
/>
<dependency>
    <dependentAssembly>
        <assemblyIdentity
            type="win32"
            name="Microsoft.Windows.Common-Controls"
            version="6.0.0.0"
            processorArchitecture="*"
            publicKeyToken="6595b64144ccf1df"
            language="*"
        />
    </dependentAssembly>
</dependency>
 <trustInfo xmlns="urn:schemas-microsoft-com:asm.v3">
   <security>
     <requestedPrivileges>
      <requestedExecutionLevel level="requireAdministrator" uiAccess="false"/>
      </requestedPrivileges>
   </security>
 </trustInfo>
</assembly>

go get github.com/akavel/rsrc 
执行 rsrc.exe -manifest ico.manifest -o app.syso -ico app.ico 这样会生成一个叫做app.syso的文件,把这个文件和main.go放到一起

然后直接编译即可

3.利用strings.Contains判断字符串是否存在

if strings.Contains("try", "t")  {  //如果存在的话，会返回true
    fmt.Println("t字符存在与try字符串中")
} else {
   fmt.Println("t字符不存在与try字符串中")
	}

4.设置国内软件源 GOPROXY=https://goproxy.cn,direct

5.golang编译时去除文件相关信息

go build -trimpath -ldflags="-w -s"
