<h3>安装</h3>
<p>go get&nbsp;https://github.com/kirinlabs/HttpRequest</p>
<h3>发送请求</h3>
<p><strong>导入HttpRequest</strong></p>
<div class="cnblogs_Highlighter">
<pre class="brush:go;gutter:true;">import "github.com/kirinlabs/HttpRequest"</pre>
</div>
<p><strong>实例化</strong></p>
<div class="cnblogs_Highlighter">
<pre class="brush:go;gutter:true;">req := HttpRequest.NewRequest()</pre>
</div>
<p><strong>Get请求</strong></p>
<p>然后，尝试获取某个网页。我们来获取 Github 的公共时间线</p>
<p>返回一个res的Response对象和err的Error对象</p>
<div class="cnblogs_Highlighter">
<pre class="brush:go;gutter:true;">res,err := req.Get("https://api.github.com/events")</pre>
</div>
<p><strong>Post 请求</strong></p>
<div class="cnblogs_Highlighter">
<pre class="brush:go;gutter:true;">//无参请求
res,err := req.Post("https://www.baidu.com")


//请求体为文本
res,err := req.Post("https://www.baidu.com","hello")


//请求体为Json字符串
res,err := req.Post("https://www.baidu.com","{\"name\":\"github\"}")


//map传参
res.err := req.Post("https://www.baidu.com",mapinterface{}{
    "name":"github",
    "type":1,
})</pre>
</div>
<p>&nbsp;也可以不用实例化，直接发送请求</p>
<p><strong>快速发送Get请求</strong></p>
<div class="cnblogs_Highlighter">
<pre class="brush:go;gutter:true;">res,err := HttpRequest.Get("https://www.baidu.com")

res,err := HttpRequest.Get("https://www.baidu.com","title=baidu")</pre>
</div>
<p><strong>快速发送Post请求</strong></p>
<div class="cnblogs_Highlighter">
<pre class="brush:go;gutter:true;">res,err := HttpRequest.Post("https://www.baidu.com")

res,err := HttpRequest.Post("https://www.baidu.com","title=baidu&amp;type=pdf")

res,err := HttpRequest.Post("https://www.baidu.com",mapinterface{}{
"title":"baidu",
})
</pre>
</div>
<p><strong>快速发送JSON请求</strong></p>
<div class="cnblogs_Highlighter">
<pre class="brush:go;gutter:true;">res,err := HttpRequest.JSON().Post("https://www.baidu.com",mapinterface{}{
    "title":"baidu",
})

res,err := HttpRequest.JSON().Post("https://www.baidu.com",`{"title":"baidu","type":"pdf"}`)</pre>
</div>
<h3><strong>传递URL参数</strong></h3>
<p>你想为URL的查询字符串(query string)传递数据。如：手工构建URL,http://www.baidu.com/index?key=value。HttpRequest允许你使用第2个参数以字符串"id=100&amp;name=github"或mapinterface{}{"id":10,"name":"github"}字典的形式把数据传递给URL：</p>
<p><strong>手工传参</strong></p>
<div class="cnblogs_Highlighter">
<pre class="brush:go;gutter:true;">res,err := req.Get("https://www.baidu.com/index?name=github")</pre>
</div>
<p><strong>字符串传参</strong></p>
<div class="cnblogs_Highlighter">
<pre class="brush:go;gutter:true;">res,err := req.Get("https://www.baidu.com/index?name=github","id=100&amp;type=1")</pre>
</div>
<p><strong>map传参</strong></p>
<div class="cnblogs_Highlighter">
<pre class="brush:go;gutter:true;">res,err := req.Get("https://www.baidu.com/index?name=github",mapinterface{}{
    "id":10,
    "type":1,
})</pre>
</div>
<h3>响应内容</h3>
<p><strong>能读取服务器响应的内容</strong></p>
<div class="cnblogs_Highlighter">
<pre class="brush:go;gutter:true;">res,err := req.Post("https://api.github.com/events")</pre>
</div>
<p><strong>&nbsp;获取服务器返回的内容</strong></p>
<div class="cnblogs_Highlighter">
<pre class="brush:go;gutter:true;">body,err := res.Body()

fmt.Println(string(body))</pre>
</div>
<p><strong>获取服务器响应状态码</strong></p>
<div class="cnblogs_Highlighter">
<pre class="brush:go;gutter:true;">res.StatusCode()</pre>
</div>
<p><strong>获取服务器响应Headers</strong></p>
<div class="cnblogs_Highlighter">
<pre class="brush:go;gutter:true;">res.Headers()</pre>
</div>
<p>返回一个mapstring的字典</p>
<p><strong>获取请求响应时间</strong></p>
<div class="cnblogs_Highlighter">
<pre class="brush:go;gutter:true;">res.Time()</pre>
</div>
<h3>Json响应内容</h3>
<p>HttpRequest内置JSON解码，来解析JSON数据</p>
<div class="cnblogs_Highlighter">
<pre class="brush:go;gutter:true;">//Format the json return value
body, err := res.Json()

fmt.Println(body)</pre>
</div>
<p>如果JSON解码失败，会返回一个err错误</p>
<h3>定制请求头</h3>
<p>如果想为请求添加HTTP头部信息，只需要简单的传一个map给SetHeaders方法</p>
<div class="cnblogs_Highlighter">
<pre class="brush:go;gutter:true;">req.SetHeaders(mapstring{
    "Content-Type":"application/json",
    "Source":"api",
})</pre>
</div>
<p>注：所有header值必须是字符串，SetHeaders可以多次调用，如果Key重复则会覆盖前面设置的值</p>
<h3>BasicAuth 认证</h3>
<p>如果想为请求添加HTTP头部信息，只需要简单的传一个map给SetHeaders方法</p>
<div class="cnblogs_Highlighter">
<pre class="brush:go;gutter:true;">req.SetBasicAuth("username","password")</pre>
</div>
<p>&nbsp;</p>
<h3>JSON请求</h3>
<p>如果想以json方式发送请求，HttpRequest支持2种方式</p>
<p><strong>设置Header头部信息</strong></p>
<div class="cnblogs_Highlighter">
<pre class="brush:go;gutter:true;">req.SetHeaders(mapstring{"Content-Type":"application/json"})

req.Post("https://www.baidu.com","{\"name\":\"github\"}")</pre>
</div>
<p><strong>调用req.JSON()内置方法</strong></p>
<div class="cnblogs_Highlighter">
<pre class="brush:go;gutter:true;">//直接发磅Json字符串参数
res,err := req.JSON().Post("https://www.baidu.com","{\"name\":\"github\"}")

//自动将Map以Json方式发送参数
res,err := req.JSON().Post("https://www.baidu.com",mapinterface{}{
    "name":"github"
})</pre>
</div>
<h3>Cookie</h3>
<div class="cnblogs_Highlighter">
<pre class="brush:go;gutter:true;">req.SetCookies(mapstring{
    "name":"jason"
})</pre>
</div>
<h3><span style="font-size: 1.17em">超时</span></h3>
<div class="cnblogs_Highlighter">
<pre class="brush:go;gutter:true;">req.SetTimeout(5)</pre>
</div>
<h3>关闭证书验证</h3>
<p>当请求https协议时提示x509: certificate signed by unknown authority时，可关闭证书验证</p>
<div class="cnblogs_Highlighter">
<pre class="brush:go;gutter:true;">req.SetTLSClient(&amp;tls.Config{InsecureSkipVerify: true})</pre>
</div>
<h3>调试模式</h3>
<div class="cnblogs_Highlighter">
<pre class="brush:go;gutter:true;">req.Debug(true)</pre>
</div>
<h3>连接操作</h3>
<p>而且还支持连接操作</p>
<div class="cnblogs_Highlighter">
<pre class="brush:go;gutter:true;">req := HttpRequest.NewRequest().Debug(true).SetTimeout(5).SetHeader()</pre>
</div>
<h3 id="Respone%E5%AF%B9%E8%B1%A1">Respone对象</h3>
<div class="cnblogs_Highlighter">
<pre class="brush:go;gutter:true;">获取返回的Response对象
resp.Response()

获取返回码
resp.StatusCode()

获取Body主体信息   
resp.Body()

获取请求耗时
resp.Time() string   单位是毫秒

获取真实Url
res.Url()
</pre>
</div>
