Question

我无法通过python（Flask）发送http post请求。

这是我的python代码。

import json
from flask import Flask, render_template, request, jsonify
import requests
app = Flask(__name__)


@app.route("/",methods=['GET','POST'])
def home():
    if request.method == 'POST':
        #user inputs
        value1 = request.form.get('first')
        value2 = request.form.get('second')
        value3 = request.form.get('third')


        #api call 
        url = 'http://myapiurl.com/ws/spm/spm-general'
        payload = {"perfid" : {0}, "section" : {"hostname" : {1}, "iteration" : {2}, "sectionname" : "sysstat_M"}.format(value1,value2,value3)}



        r = requests.post(url, data=json.dumps(payload))

        #print(r.status_code, r.headers['content-type'])
        #print(r.text)

        returnData["result"] = json.loads(r.text)
        return jsonify(returnData)

    return render_template('index.html')





if __name__ == '__main__':
    app.run(debug=True)

我正在使用FLASK。我得到的错误是：

 payload = {"perfid" : {0}, "section" : {"hostname" : {1}, "iteration" : {2},
 "sectionname" : "sysstat_M"}.format(value1,value2,value3)}
AttributeError: 'dict' object has no attribute 'format'

当我在简单的python（没有Flask）中尝试它时，它可以工作，但我无法使用Flask

这是有效的代码：

import json
import requests


url = 'http://myapiurl.com/ws/spm/spm-general'
payload = {"perfid" : 124, "section" : {"hostname" : "10.161.146.94/10.161.146.90", "iteration" : "1", "sectionname" : "sysstat_M"}}

r = requests.post(url, data=json.dumps(payload))


print(r.status_code, r.headers['content-type'])
print(r.text)

Answer 1

您似乎将dict与str混淆了（payload = { "perfid" : value1, "section" : { "hostname" : value2, "iteration" : value3, "sectionname" : "sysstat_M" } }方法）。

只需将变量放入字典文字：

<input class="max1" />
<table>
    <tr>
        <td colspan="5">Deadlift</td>
    </tr>
    <tr>
        <td align="center">
            <span  class="perc1">75</span>% x 3</td>
        <td align="center">
            <span class="perc">78</span>% x 2</td>
        <td align="center">
            <span class="perc">83</span>% x 1</td>
        <td align="center">
            <span class="perc">85</span>% x 1</td>
    </tr>
    <tr>
        <td class="weight1"></td>
        <td class="weight"></td>
        <td class="weight"></td>
        <td class="weight"></td>
    </tr>
</table>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script>
$(document).ready(function () {
    $('input').keyup(function () {
        cal(this);
    });
});

function cal(obj) {
    var cal1, perc1, result;
    cal1 = parseFloat(obj.value);
    perc1 = parseFloat($('.perc1').text());


    result = (cal1*perc1)/100;
    $('.weight1').html(result);
}
</script>

Answer 2

payload = {"perfid" : value1, "section" : {"hostname" : value2, "iteration" : value3, "sectionname" : "sysstat_M"}

format是string的函数，请看一下：https://docs.python.org/2/library/functions.html#format

python请求库中的HTTP Post出错
