Question

我刚刚用ubuntu 16.04，nginx 1.10.3和php 7.0创建了一个新的vps，并将我的工作站点复制到它。旧网站是在php5.6上运行完美无缺。

问题在于某些东西正在将我的编码加号转换为空格。我可以证明这是真正的请求是使用文档检查器编码+ as％2B但直接卷曲测试也失败了：

Test 1:
curl "my_https_url" --data "details=asdf+%2B+asdf" --compressed
array(1) { ["details"]=> string(11) "asdf   asdf" } <-- 3 spaces

Test 2:
curl "my_https_url" --data-urlencoded "details=asdf+%2B+asdf" --compressed
array(1) { ["details"]=> string(11) "asdf + asdf" } <-- perfect

Test 3:
$.post("my_https_url",{details:"asdf + asdf"})
Document Inspector Encoded Form Data: details=asdf+%2B+asdf
array(1) { ["details"]=> string(11) "asdf   asdf" } <-- 3 spaces

Test 4:
$.post("my_https_url",{details:"asdf %2B asdf"})
Document Inspector Encoded Form Data: details=asdf+%252B+asdf
array(1) { ["details"]=> string(11) "asdf + asdf" } <-- perfect

Test 5:
$.post("my_https_url",{details:"asdf+%2B+asdf"})
Document Inspector Encoded Form Data: details=asdf%2B%252B%2Basdf
array(1) { ["details"]=> string(11) "asdf + asdf" } <-- perfect

Test 6:
$.post("my_https_url",{details:encodeURI("asdf + asdf")})
Document Inspector Encoded Form Data: details=asdf%2520%2B%2520asdf
array(1) { ["details"]=> string(11) "asdf   asdf" } <-- 3 spaces

Test 7:
$.post("my_https_url",{details:encodeURIComponent("asdf + asdf")})
Document Inspector Encoded Form Data: details=details=asdf%2520%252B%2520asdf
array(1) { ["details"]=> string(11) "asdf + asdf" } <-- perfect

Test 8:
$.post("my_https_url",$('<form><input name="details" value="asdf + asdf"></form>').serialize())
Document Inspector Encoded Form Data: details=details=details=asdf+%2B+asdf
array(1) { ["details"]=> string(11) "asdf   asdf" } <-- 3 spaces

Test 9:
$.post("my_https_url",encodeURIComponent($('<form><input name="details" value="asdf + asdf"></form>').serialize()))
Document Inspector Encoded Form Data: details%3Dasdf%2520%252B%2520asdf
array(0) {} <-- not working

<?php
var_dump($_POST);
// I am expecting "asdf + asdf"

是否存在导致此问题的php扩展或是否为nginx？我包括了两者的配置。

Answer 1

在提交数据之前，您需要在值中对特殊字符进行编码。将您的值包裹在encodeURIComponent。

中

$.post("my_https_url",{details:encodeURIComponent("asdf + asdf")})

Answer 2

解决：我忘了我在主域上有一个代理服务器。我为@johnBaker创建了一个绕过代理服务器的子域，它可以正常工作。对代理配置的简单修复，它的工作原理！感谢大家参与我的野鹅追逐。
