我有一个类似
的JSON文件{
"unknown1":
[
{"text": "random text again",
"time": "Thu May 15 19:21:59 +0000 2016"},
"text": "akmfkdlm safsa fasffalmfa",
"time": "Thu May 21 09:53:51 +0000 2016"}
]
"unknown2":
[
"text": "fsda lmfalmfa",
"time": "Thu May 21 09:53:51 +0000 2016"},
]
}
JSON中的第一项是随机(未知)标签,可以有任意数量的这些未知数。在这些未知数内总是有一堆text
/ time
配对。
我正在尝试将每个text
发送到我的REST post服务,该服务接受格式为
text: "foo bar bat",
mime_type: "text/html",
extract_type: "HP" # HP, MP
所以当我尝试运行我的代码并且不确定该怎么做时,我收到此错误。
这是我的代码:
import json
import requests
with open('locations_stripped.json') as data_file:
data = json.load(data_file)
headers = {'Content-Type' : 'application/json'}
for thing in data:
for text, time in data.iteritems():
print text
body = [{ "text": text , "mime_type": "text/html", "extract_type": "HP"}]
r = requests.post('localhost:3003/api/extract/run', data=body, headers=headers)
print (r.content)
这是错误:
$ python filterrest.py
unknown1
Traceback (most recent call last):

for k, vs in to_key_val_list(data):
ValueError: too many values to unpack
有一点需要注意的是它是打印错误的文本(“unknown1”而不是“随机文本”),我不知道如何让它只打印文本。
对此有何帮助?
更新
根据每个人的回答/评论我改变了我的代码
...
for thing in data:
for text in data[thing]:
print text['text']
并按照我的预期打印文本['text']。问题在于我在做我的要求的方式。我将我的代码更改为测试并将数据设置为我知道应该工作的内容(我通过Postman运行)。
更改了代码:
r = requests.post('localhost:3003/api/extract/run', data='Hello. Where does the brown fox go?', headers=headers)
预期回应:
[
{
"score": 0.30253747367501777,
"tag": "HP",
}
]
相反,打印的内容看起来像整个HTML页面。

假设你有一个有效的json。您首先需要遍历与“未知”键对应的列表,现在此列表再次包含字典
使用text
time
个密钥。
for unknown_key in data:
for obj in data[unknown_key]:
body = { "text": obj['text'] , "mime_type": "text/html", "extract_type": "HP"}
r = requests.post('localhost:3003/api/extract/run', data=body, headers=headers)
print (r.content)

关于问题的第1部分:
multiple
通过此循环,您无法获得$allowed_filenames = [
'AGL_001.txt',
];
if(isset($_FILES['upload1']['name'])){
//$errors= array();
$file_name = $_FILES['upload1']['name'];
$file_size =$_FILES['upload1']['size'];
$file_tmp =$_FILES['upload1']['tmp_name'];
$file_type=$_FILES['upload1']['type'];
$file_ext=strtolower(end(explode('.',$_FILES['upload1']['name'])));
//$img_loc = $file_name.'.'.$file_ext;
if (in_array($file_name, $allowed_filenames)) {
move_uploaded_file($file_tmp,"uploads/".$file_name);
} else {
// log an error
}
}
。您的更新:
for thing in data:
for text, time in data.iteritems():
是对的。你的text
是对的。下一个问题是:
for thing in data:
for text in data[thing]:
print text['text']
现在查看模块请求:
的文档通常,您希望发送一些表单编码数据 - 非常类似于HTML 形成。为此,只需将字典传递给data参数即可。您的 数据字典将在请求时自动进行表单编码 是
有很多时候你想发送不是的数据 形式编码。如果传入字符串而不是dict,则传入该数据 将直接发布。
对于关键字参数headers
,您必须提供body = [{ "text": text , "mime_type": "text/html", "extract_type": "HP"}]
r = requests.post('localhost:3003/api/extract/run', data=body, headers=headers)
或有效的json data
。问题中的变量dict
一直是str
,而您的更新中的变量是无效的json body
。有两种解决方案:
list
或者
str
但请求 doc说:
您可以直接传递它,而不是自己编码 使用json参数(在版本2.4.2中添加),它将是 自动编码
因此,从版本 2.4.2 开始,最好使用关键字参数body = { "text": text , "mime_type": "text/html", "extract_type": "HP"}
# Dont't forget: dict will be used to send form-encoded data
# It will work. But not a intended solution for json data
r = requests.post('localhost:3003/api/extract/run', data=body, headers=headers)
代替import json
body = { "text": text , "mime_type": "text/html", "extract_type": "HP"}
r = requests.post('localhost:3003/api/extract/run', data=json.dumps(body), headers=headers)
来发送json数据。所以它是最好的溶剂:
json
<强>综述强>
我使用这个来源:
data
代码:
body = { "text": text , "mime_type": "text/html", "extract_type": "HP"}
r = requests.post('localhost:3003/api/extract/run', json=body, headers=headers)
P / S:我不了解你的服务器,所以我无法测试它。我希望,它有效。
