将JSON字符串转换为字典Not列表
将JSON字符串转换为字典Not列表
提问于 2013-10-21 05:56:21
我尝试传入一个JSON文件并将数据转换为字典。
到目前为止，我所做的是：
import json
json1_file = open('json1')
json1_str = json1_file.read()
json1_data = json.loads(json1_str)我期望json1_data是一个dict类型，但当我用type(json1_data)检查它时，它实际上是一个list类型。
我遗漏了什么？我需要这是一个字典，这样我就可以访问其中的一个密钥。

您可以使用以下内容：
import json
with open('<yourFile>.json', 'r') as JSON:
json_dict = json.load(JSON)
# Now you can use it like dictionary
# For example:
print(json_dict["username"])Stack Overflow用户

我正在使用一个REST API的Python代码，所以这是为那些在类似项目中工作的人准备的。
我使用POST请求从URL提取数据，原始输出为JSON。由于某些原因，输出已经是一个字典，而不是一个列表，我能够立即引用嵌套的字典键，如下所示：
datapoint_1 = json1_data['datapoints']['datapoint_1']datapoint_1在数据点字典中的位置。

使用javascript ajax从get方法传递数据。
**//javascript function
function addnewcustomer(){
//This function run when button click
//get the value from input box using getElementById
var new_cust_name = document.getElementById("new_customer").value;
var new_cust_cont = document.getElementById("new_contact_number").value;
var new_cust_email = document.getElementById("new_email").value;
var new_cust_gender = document.getElementById("new_gender").value;
var new_cust_cityname = document.getElementById("new_cityname").value;
var new_cust_pincode = document.getElementById("new_pincode").value;
var new_cust_state = document.getElementById("new_state").value;
var new_cust_contry = document.getElementById("new_contry").value;
//create json or if we know python that is call dictionary.
var data = {"cust_name":new_cust_name, "cust_cont":new_cust_cont, "cust_email":new_cust_email, "cust_gender":new_cust_gender, "cust_cityname":new_cust_cityname, "cust_pincode":new_cust_pincode, "cust_state":new_cust_state, "cust_contry":new_cust_contry};
//apply stringfy method on json
data = JSON.stringify(data);
//insert data into database using javascript ajax
var send_data = new XMLHttpRequest();
send_data.open("GET", "http://localhost:8000/invoice_system/addnewcustomer/?customerinfo="+data,true);
send_data.send();
send_data.onreadystatechange = function(){
if(send_data.readyState==4 && send_data.status==200){
alert(send_data.responseText);
}
}
}django视图
def addNewCustomer(request):
#if method is get then condition is true and controller check the further line
if request.method == "GET":
#this line catch the json from the javascript ajax.
cust_info = request.GET.get("customerinfo")
#fill the value in variable which is coming from ajax.
#it is a json so first we will get the value from using json.loads method.
#cust_name is a key which is pass by javascript json.
#as we know json is a key value pair. the cust_name is a key which pass by javascript json
cust_name = json.loads(cust_info)['cust_name']
cust_cont = json.loads(cust_info)['cust_cont']
cust_email = json.loads(cust_info)['cust_email']
cust_gender = json.loads(cust_info)['cust_gender']
cust_cityname = json.loads(cust_info)['cust_cityname']
cust_pincode = json.loads(cust_info)['cust_pincode']
cust_state = json.loads(cust_info)['cust_state']
cust_contry = json.loads(cust_info)['cust_contry']
#it print the value of cust_name variable on server
print(cust_name)

print(cust_cityname)
print(cust_pincode)

print(cust_contry)
