strange python issue, 'unicode' object has no attribute 'read'
提问by Lin Ma
Here is my code and does anyone have any ideas what is wrong? I open my JSON contentdirectly by browser and it works,
这是我的代码，有没有人知道有什么问题？我直接通过浏览器打开我的 JSON 内容，它可以工作，
data = requests.get('http://ws.audioscrobbler.com/2.0/?method=library.getartists&api_key=4c22bd45cf5aa6e408e02b3fc1bff690&user=joanofarctan&format=json').text
data = json.load(data)
print type(data)
return data
thanks in advance, Lin
提前致谢，林

This error raised because the datais a unicode/str variable, change the second line of your code to resolve your error:
引发此错误data是因为它是 unicode/str 变量，请更改代码的第二行以解决错误：
data = json.loads(data)
json.loadget a file object in first parameter position and call the readmethod of this.
json.load在第一个参数位置获取一个文件对象并调用readthis的方法。
Also you can call the jsonmethod of the response to fetch data directly:
您也可以调用json响应的方法直接获取数据：
response = requests.get('http://ws.audioscrobbler.com/2.0/?method=library.getartists&api_key=4c22bd45cf5aa6e408e02b3fc1bff690&user=joanofarctan&format=json')
data = response.json()

requests.get(…).textreturns the content as a single (unicode) string. The json.load()function however requires a file-like argument.
requests.get(…).text将内容作为单个（unicode）字符串返回。json.load()然而，该函数需要一个类似文件的参数。
The solution is rather simple: Just use loadsinstead of load:
解决方案相当简单：只需使用loads代替load：
data = json.loads(data)
An even better solution though is to simply call json()on the response object directly. So don't use .textbut .json():
更好的解决方案是直接调用json()响应对象。所以不要使用.text但是.json()：
data = requests.get(…).json()
While this uses json.loadsitself internally, it hides that implementation detail, so you can just focus on getting the JSON response.
虽然json.loads它在内部使用自身，但它隐藏了实现细节，因此您可以专注于获取 JSON 响应。
