如何在 Linux 终端中使用 curl POST 功能在 python 中创建文档

Question

我正在尝试将新记录添加到 python 文档中，我认为我遇到了由 curl post 函数引起的问题。我已将 python 文件和 posting 时收到的错误附加到我的 url。谁能指出我正确的方向。

我不明白错误代码以确定问题是否来自 python 代码，但我确实怀疑 curl url.

python 错误：

Answer 1

问题是，在您的 curl 请求中的 json 中的某个时刻，您使用了 “ 而不是 "。因此 json 解析器抛出一个错误。

所以

"business_name" : “ACME Test INC."

写：

"business_name" : "ACME Test INC."

Answer 2

不确定你是否解决了这个问题，但我们开始吧。 Jakob 是正确的，您使用 “ 而不是 " 接下来，从您要插入的文档中获取值

data = request.json (Contains parsed content)

给你需要的变量赋值比如id

id = data['id']

将所有值存储在一个字典变量中（我认为这样更干净）

document = {"id":myid,"certificate_number":cert_number,"business_name":bus_name,"date":date,"result":result,"sector":sector}

最后，使用 insert_one 并捕获错误

try:
    collection.insert_one(document)
    print("CREATED NEW DOCUMENT")

except Exception as e:
    print("ERROR: ", e)

另外，有几种方法可以解决您提到的 cURL 请求的 "space" 问题。一种方法是简单地在空格之间添加一个 %20，如下所示：

ACME%20TEST%20INC.

希望对您有所帮助。
