HTTP CLIENTS AND REMOTE INTERACTION WITH TOOLS

http apis

http.Get(url string) (resp *Response, err error)
http.Head(url string) (resp *Response, err error)
http.Post(url string, bodyType string, body io.Reader) (resp *Response, err error)

POST

package main
import (
    "fmt"
    "log"
    "net/http"
    "net/url"
    "strings"
)
func main()  {
    form := url.Values{}
    form.Add("username","srat")
    form.Add("password","123456")
    url := "http://xxx/login"
    contentType := "application/x-www-form-urlencoded"
    if res,err := http.Post(url,contentType,strings.NewReader(form.Encode()));err!=nil{
        log.Fatal("conn err")
        defer  res.Body.Close()
    }else {
        resp,_ := ioutil.Readall(res.Body)
        fmt.Println(string())
    }
}

或者

form := url.Values{}
    form.Add("username","srat")
    form.Add("password","123456")
    url := "http://xxx/login"
    //contentType := "application/x-www-form-urlencoded"
    if res,err := http.PostForm(url,form);err!=nil{
        log.Fatal("conn err")
    }else {
        resp,_ := ioutil.Readall(res.Body)
        fmt.Println(string(resp))
    }

Using Structured Response Parsing

response结构体

type Response struct {
    Status     string // e.g. "200 OK"
    StatusCode int    // e.g. 200
    Proto      string // e.g. "HTTP/1.0"
    ProtoMajor int    // e.g. 1
    ProtoMinor int    // e.g. 0
    Header Header
    Body io.ReadCloser
    ContentLength int64
    TransferEncoding []string
    Close bool
    Uncompressed bool
    Trailer Header
    Request *Request
    TLS *tls.ConnectionState
}

解析json数据

解析Fofa返回json

package main
import (
    "encoding/base64"
    "encoding/json"
    "fmt"
    "io/ioutil"
    "log"
    "net/http"
    "os"
)
type info struct {
    Mode string `json:"mode"` // tag 即解析json的别名
    Error bool `json:"error"`
    Query string `json:"query"`
    Page int `json:"page"`
    Size int `json:"size"`
    Results [][]string `json:"results"`
}
var (
    key = "xxxxxxxxxxxxxxxxxxxxxxxxxxx"
    mail = "xxxxxxxxxxxxxxx"
    query string
)
func main() {
    a := []byte("domain=nuist.edu.cn")
    query = base64.StdEncoding.EncodeToString(a) // base64
    url := fmt.Sprintf("https://fofa.so/api/v1/search/all?email=%s&key=%s&qbase64=%s",mail,key,query)
    res,err := http.Get(url)
    var i info
    if err != nil{
        log.Fatal(err)
        os.Exit(0)
    }else {
        if resp,err := ioutil.ReadAll(res.Body);err!=nil{
            log.Fatal("err")
            os.Exit(0)
        }else {
            fmt.Println(string(resp))
            if err = json.Unmarshal(resp,&i);err!=nil{ // json反序列化
                fmt.Println(err)
                os.Exit(0)
            }
        }
        results :=i.Results
        for _,v :=range (results){
            fmt.Println(v[0])
        }
    }
}

这里需要注意的点比较多。声名接收json反序列化结构体的时候，成员变量首字符要大写，否则就会出现反序列化赋值无法成功。还有就是Unmarshal接收参数为指针，不能直接传入变量实体。这是个非常简单的Demo版本，好在Fofa的一切查询都是基于语法，后期想要修改也比较容易。
