Django 后台保存 uni-app 前端上传的图片

可能会遇到的错误：

django.http.multipartparser.MultiPartParserError: Invalid boundary in multipart: None

StackOverflow 上面有人的解答：

It looks like you were paying careful attention to the following note in the django-rest-framework docs:

Note: When developing client applications always remember to make sure you're setting the Content-Type header when sending data in an HTTP request.

If you don't set the content type, most clients will default to using 'application/x-www-form-urlencoded', which may not be what you wanted.

解决方法 就是 在提交的时候，不要添加 headers 头部信息。

前端代码如下：

uni.uploadFile({
    url:your_url,
        //  header 注释掉
    // header: {  
    //     'Content-Type': "multipart/form-data",
    // },  
    filePath:that.imgList[0],
    name:'imgs',
    formData:{'uName': that.uName},
    success(res) {
        console.log('上传成功！')
    }
})

后台代码：

def submitOrders(request):
    img = request.FILES.get('imgs')
    uName = request.POST.get('uName')
    print(uName)
    print('img:', img)
    if img:
        img_path = os.path.join('static/image/', img.name)
        with open(img_path, 'wb') as fi:
            for i in img.chunks():
                fi.write(i)
