| 一、form表单上传 |
1.页面代码
<!DOCTYPE html><html lang="en"><head> ???<meta charset="UTF-8"> ???<title>Title</title></head><body><form action="{% url ‘upload‘ %} " method="post" enctype="multipart/form-data"> ???{% csrf_token %} ???<input type="file" name="img"> ???<input type="submit"></form></body></html>2.后端view函数处理
def upload(request): ???if request.method=="GET": ???????return ?render(request,‘upload.html‘) ???elif request.method=="POST": ???????res={"status":"success","code":999} ???????img_obj=request.FILES.get(‘img‘)#获取文件对象 ???????with open(os.path.join(‘static‘,img_obj.name),"wb") as f: ???????????for chunk in img_obj.chunks(chunk_size=1024): ???????????????f.write(chunk) ???????return HttpResponse(json.dumps(res))| 二、利用Jquery中ajax+FormData实现上传文件 |
上传步骤：
1.页面代码
<!DOCTYPE html><html lang="en"><head> ???<meta charset="UTF-8"> ???<title>Title</title></head><body><form action="{% url ‘upload‘ %} " method="post" enctype="multipart/form-data"> ???{% csrf_token %} ???<input type="file" name="img"></form><span style="padding: 5px;color: royalblue" onclick="Jqajax();">jq上传</span><script type="text/javascript" src="/static/jquery-2.1.1.min.js"></script><script type="text/javascript" src="/static/jquery.cookie.js"></script><script> ???function Jqajax() { ??????var file_obj=$(‘input[name="img"]‘)[0].files[0];//获取dom形式的文件对象 ??????var form_obj=new FormData(); ??//创建formdata对象 ??????form_obj.append(‘img‘,file_obj); ??//将文件对象加载formdata中 ???????$.ajaxSetup({ ????????????????????//设置csrf_token ???????????beforeSend: function (xhr, settings) { ???????????????????xhr.setRequestHeader("X-CSRFToken", $.cookie("csrftoken")); ???????????} ???????}); ??????$.ajax({ ??????????type: ‘POST‘, ??????????url: ‘{% url ‘upload‘ %}‘, ??????????data: form_obj,//指明发送的文件对象 ??????????processData: false, // 告诉jquery要传输data对象 ??????????contentType: false, ??// 告诉jquery不需要增加请求头对于contentType的设置 ???????????????success: function (data) { ???????????????????console.log(data) ??????????} ??????}) ???}</script></body></html>后端处理逻辑不变
