params = { "callback": "jQuery18303118265739643302_1690164521076", "fundCode": "400015", "pageIndex": "6", "pageSize": "20", "startDate": "", "endDate": "", "_": "1690165052233" } 请根据这段代码：http://api.fund.eastmoney.com/f10/lsjz?callback=jQuery18303118265739643302_1690164521076&fundCode=400015&pageIndex=6&pageSize=20&startDate=&endDate=&_=1690165052233 重新写出正确的params

根据给出的代码，重新编写正确的 `params` 如下：

params = {
  "callback": "jQuery18303118265739643302_1690164521076",
  "fundCode": "400015",
  "pageIndex": "6",
  "pageSize": "20",
  "startDate": "",
  "endDate": "",
  "_": "1690165052233"
}

根据上述 `params`，可以构建正确的 URL 如下：

http://api.fund.eastmoney.com/f10/lsjz?callback=jQuery18303118265739643302_1690164521076&fundCode=400015&pageIndex=6&pageSize=20&startDate=&endDate=&_=1690165052233

import requests import time headers = { 'user-agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/76.0.3809.132 Safari/537.36', 'referer': 'http://fund.eastmoney.com/400015.html?spm=search' } params = { "callback": "jQuery18303118265739643302_1690164521076", "fundCode": "400015", "pageIndex": "6", "pageSize": "20", "startDate": "", "endDate": "", "_": "1690165052233" } url = 'http://api.fund.eastmoney.com/f10/lsjz' res = requests.get(url, params=params, headers=headers) try: data = res.json() LSJZ = data['Data']['LSJZList'] for i in LSJZ: print("单位净值：", i['DWJZ']) except ValueError: print("无效的JSON数据") 输出的是“无效的JSON数据”

根据你提供的代码，可能是因为获取到的响应数据不是有效的 JSON 格式导致的。可以尝试打印一下获取到的响应内容，看看是否有其他错误信息。

可以修改代码如下：

import requests
import time

headers = {
    'user-agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/76.0.3809.132 Safari/537.36',
    'referer': 'http://fund.eastmoney.com/400015.html?spm=search'
}

params = {
    "callback": "jQuery18303118265739643302_1690164521076",
    "fundCode": "400015",
    "pageIndex": "6",
    "pageSize": "20",
    "startDate": "",
    "endDate": "",
    "_": "1690165052233"
}

url = 'http://api.fund.eastmoney.com/f10/lsjz'
res = requests.get(url, params=params, headers=headers)

try:
    data = res.json()
    print(data)  # 打印获取到的响应内容
    LSJZ = data['Data']['LSJZList']
    for i in LSJZ:
        print("单位净值：", i['DWJZ'])
except ValueError:
    print("无效的JSON数据")

通过打印获取到的响应内容，可以更好地了解返回的数据结构，并找出问题所在。

import requests import time headers = { 'user-agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/76.0.3809.132 Safari/537.36', 'referer': 'http://fund.eastmoney.com/400015.html?spm=search' } params = { "callback": "jQuery18303118265739643302_1690164521076", "fundCode": "400015", "pageIndex": "6", "pageSize": "20", "startDate": "", "endDate": "", "_": "1690165052233" } url = 'http://api.fund.eastmoney.com/f10/lsjz' res = requests.get(url, params=params, headers=headers) LSJZ = res.json()['Data']['LSJZList'] for i in LSJZ: print("单位净值：", i['DWJZ']) 给出的代码还是运行不了，并有以下错误提示： File "C:\Users\刘岩\.spyder-py3\temp.py", line 22, in <module> LSJZ = res.json()['Data']['LSJZList'] File "F:\anaconda\anaconda\lib\site-packages\requests\models.py", line 975, in json raise RequestsJSONDecodeError(e.msg, e.doc, e.pos) JSONDecodeError: Expecting value

这个错误提示表明在尝试解析响应的JSON数据时出现了问题。错误的原因可能是，返回的响应内容不是有效的JSON格式。

为了解决这个问题，你可以添加一些错误处理代码来检查响应是否成功，并确保返回的数据是有效的JSON格式。以下是修改后的代码：

import requests
import time

headers = {
  'user-agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/76.0.3809.132 Safari/537.36',
  'referer': 'http://fund.eastmoney.com/400015.html?spm=search'
}

params = {
  "callback": "jQuery18303118265739643302_1690164521076",
  "fundCode": "400015",
  "pageIndex": "6",
  "pageSize": "20",
  "startDate": "",
  "endDate": "",
  "_": "1690165052233"
}

url = 'http://api.fund.eastmoney.com/f10/lsjz'
res = requests.get(url, params=params, headers=headers)

try:
    data = res.json()
    LSJZ = data['Data']['LSJZList']
    for i in LSJZ:
        print("单位净值：", i['DWJZ'])
except ValueError:
    print("无效的JSON数据")

这个修改后的代码在解析JSON数据之前添加了一个 `try-except` 块。在 `try` 块中，我们尝试解析JSON数据并提取所需的信息。如果解析过程中出现错误，会抛出 `ValueError` 异常。在 `except` 块中，我们捕获这个异常并打印出错误信息。

通过这个修改，代码将能够处理无效的JSON数据，避免触发 `JSONDecodeError` 异常。
