Question

我目前正在使用一个应用程序（python / django / redis）来跟踪和注册农场中谷物的运动。

我的主应用程序运行正常，我现在正在尝试使我的最后一页正常工作。

该页面的目标是让用户在访问网络时将其加载到其“三星”选项卡上，然后进入该字段以收集一些要在localStorage中注册的数据。

完成操作后，他将返回网络并按加载按钮。按下按钮后，它将发送一个发布请求，告诉视图它需要从localStorage收集数据并将其放入Redis键。

这是视图的代码：

def creationField(request):
    if request.method == 'POST':
        driver = webdriver.Chrome() 
        url='XXX.X.X.XX:XXXX/XXXXXXX/XXXXXXX'
        driver.get(url)
        storage = LocalStorage(driver)

        for i in range(1,50) :
            keyCubage = 'Wagon_'+ str(i) + '_cubageWagon'
            keyLimite = 'Wagon_'+ str(i) + '_limiteWagon'
            keyCiterne = 'Wagon_'+ str(i) + '_numCiterne'
            keyPBM = 'Wagon_'+ str(i) + '_pbmWagon'
            keyTar = 'Wagon_'+ str(i) + '_tarWagon'

            cubageWagon = storage.get(keyCubage)
            limiteWagon = storage.get(keyLimite)
            numCiterne = storage.get(keyCiterne)
            pbmWagon = storage.get(keyPBM)
            tarWagon = storage.get(keyTar)

            if (cubageWagon == None or limiteWagon == None or numCiterne == None or pbmWagon == None or tarWagon == None):
                result = "Break"
                break
            else:
                result = "REDIS WORK"
                r = redis.StrictRedis(host=settings.REDIS_AD, port=settings.REDIS_PORT, db='14')
                key = 'Wagon_' + str(i)
                r.hmset(key, {'Cubage': cubageWagon, 'limite': limiteWagon, 'numCiterne': numCiterne, 'pbmWagon': pbmWagon, 'tarWagon': tarWagon})
    return render(request, 'creationField.html', locals())

LocalStorage类：

class LocalStorage:

    def __init__(self, driver) :
        self.driver = driver

    def __len__(self):
        return self.driver.execute_script("return window.localStorage.length;")

    def items(self) :
        return self.driver.execute_script( \
            "var ls = window.localStorage, items = {}; " \
            "for (var i = 0, k; i < ls.length; ++i) " \
            "  items[k = ls.key(i)] = ls.getItem(k); " \
            "return items; ")

    def keys(self) :
        return self.driver.execute_script( \
            "var ls = window.localStorage, keys = []; " \
            "for (var i = 0; i < ls.length; ++i) " \
            "  keys[i] = ls.key(i); " \
            "return keys; ")

    def get(self, key):
        return self.driver.execute_script("return window.localStorage.getItem(arguments[0]);", key)

    def set(self, key, value):
        self.driver.execute_script("window.localStorage.setItem(arguments[0], arguments[1]);", key, value)

    def has(self, key):
        return key in self.keys()

    def remove(self, key):
        self.driver.execute_script("window.localStorage.removeItem(arguments[0]);", key)

    def clear(self):
        self.driver.execute_script("window.localStorage.clear();")

    def __getitem__(self, key) :
        value = self.get(key)
        if value is None :
          raise KeyError(key)
        return value

    def __setitem__(self, key, value):
        self.set(key, value)

    def __contains__(self, key):
        return key in self.keys()

    def __iter__(self):
        return self.items().__iter__()

    def __repr__(self):
        return self.items().__str__()

我很肯定本地存储不是问题，我能够从一些js尝试的内容中进行写入/读取。

我当前的问题是，当我按下加载按钮并将帖子发送给我时，页面崩溃并出现以下错误：

Message: unknown error : unhandled inspector error:{"Code":"-32000", "message","Cannot navigate to invalid URL"}

如果我复制粘贴似乎对他无效的网址，则会加载该文件而不会出现问题，因此我不确定是什么使该网址对他无效？

Answer 1

如果您说您的网址是有效的，并且收到了无效的网址消息，请尝试以下操作：尝试将网址存储到String literals（用r'标记）

url = r'url_path_goes_here'

WebDriverException：代码为“ -3200”的未处理检查器错误
