谢谢你我想你也在遵循指南，使用sencha应用程序手表，让php代码返回给你。我在Sencha论坛上找到了这个答案，Sencha cmd提供的web服务器不支持php，它只是一个基本的HTTP web服务器。答案与另一个问题相同：如果不向我们展示php代码以及调用所述php脚本时浏览器的“网络”选项卡返回的内容，我们无法帮助您。@Alexander Done请同时显示浏览器的“网络”选项卡在调用api.php时返回的内容（屏幕截图）。@Alexander Done我希望您向我们显示的是调用php文件时返回的数据，如中所示。看来你真的不知道自己在做什么。在混合这两种方法之前，你应该先进行基本的PHP调试和基本的ExtJS调试。找到了什么答案？很抱歉，我忘了把链接放在那里，不知怎么的，我再也找不到了，但答案是cmd的Web服务器只会返回代码，而不会处理它，这就是它返回PHP代码的原因。

# sencha.cfg
#
# This is the main configuration file for Sencha Cmd. The properties defined in
# this file are used to initialize Sencha Cmd and should be edited with some
# caution.
#
# On previous versions, this file provided a way to specify the cmd.jvm.* properties
# to control the execution of the JVM. To accommodate all possible execution scenarios
# support for these properties has been removed in favor of using the _JAVA_OPTIONS
# environment variable.
#
#------------------------------------------------------------------------------
# This indicates the platform that Cmd is installed on. This is used for
# platform specific package management.
#
# Possible values: windows, osx, linux, linux-x64
#
# cmd.platform=
#------------------------------------------------------------------------------
# This is the Sencha Cmd version.
#
# THIS PROPERTY SHOULD NOT BE MODIFIED.
cmd.version=6.5.3.6
#------------------------------------------------------------------------------
# This indicates the level of backwards compatibility provided. That is to say,
# apps requiring versions between cmd.minver and cmd.version (inclusive) should
# be able to use this version.
#
# THIS PROPERTY SHOULD NOT BE MODIFIED.
cmd.minver=3.0.0.0
#------------------------------------------------------------------------------
# The folder for the local package repository. By default, this folder is shared
# by all versions of Sencha Cmd. In other words, upgrading Sencha Cmd does not
# affect the local repository.
repo.local.dir=${cmd.dir}/../repo
#------------------------------------------------------------------------------
# This is the default port to use for the Sencha Cmd Web Server.
cmd.web.port=1841
#------------------------------------------------------------------------------
# Java System Properties
#
# By setting any "system.*" properties you can set Java System Properties. For
# general information on these, see:
#
# http://docs.oracle.com/javase/tutorial/essential/environment/sysprop.html
#
#------------------------------------------------------------------------------
# Proxy Settings
#
# The primary reason to set Java System Properties is to handle HTTP Proxies.
# By default, Java uses "http.proxy*" properties to configure HTTP proxies, but
# the "java.net.useSystemProxies" option can be enabled to improve the use of
# system-configured proxy settings based on your platform. If this setting does
# not work for your proxy server setup, try disabling this setting by commenting
# it out and enabling the other settings. See also this information on proxy
# setup:
#
# http://docs.oracle.com/javase/6/docs/technotes/guides/net/proxies.html
#
# NOTE: If you find that you need to adjust these settings, you may want to do
# so in a "sencha.cfg" file one folder above this folder. The settings in that
# file override these settings, so be sure to only copy the settings you need
# to that location. The advantage to putting these settings in that location is
# that they will not be "lost" as you upgrade Cmd.
system.java.net.useSystemProxies=true
# These are the legacy options that come in to play when the above is commented
# out:
#system.http.proxyHost=proxy.mycompany.com
#system.http.proxyPort=80
#system.http.proxyUser=username
#system.http.proxyPassword=password
#------------------------------------------------------------------------------
# Merge Tool Settings
#
# To enable use of a visual merge tool to resolve merge conflicts, set the
# following property to the desired merge tool path:
#
# cmd.merge.tool=p4merge
#
# Next, to configure the arguments for the merge tool, set this property:
#
# cmd.merge.tool.args={base} {user} {generated} {out}
#
# Alternatively, the arguments for several merge tools are defined below and can
# be used in your configuration for simplicity/clarity like so:
#
# cmd.merge.tool.args=${cmd.merge.tool.args.sourcegear}
#
# NOTE: the cmd.merge.tool.args property is split on spaces *then* the tokens
# are replaced by actual files names. This avoids the need to quote arguments to
# handle spaces in paths.
#
# NOTE: Some merge tools (like SmartSynchronize) do not accept the output file
# separately so there is no way to know if the merge was completed. In this case,
# the base file is where the result is written so Cmd just copies the content of
# that file back as the result.
#
# You can add the appropriate lines to customize your Cmd configuration. See
# below for details.
# The arguments for p4merge, see below for download:
# http://www.perforce.com/product/components/perforce-visual-merge-and-diff-tools
cmd.merge.tool.args.p4merge={base} {user} {generated} {out}
# SourceGear (http://www.sourcegear.com/diffmerge/index.html)
cmd.merge.tool.args.sourcegear=--merge --result={out} {user} {base} {generated}
# kdiff3 (http://sourceforge.net/projects/kdiff3/files/kdiff3/)
cmd.merge.tool.args.kdiff3={base} {user} {generated} -o {out}
# Syntevo SmartSynchronize 3 (http://www.syntevo.com/smartsynchronize/index.html).
cmd.merge.tool.args.smartsync={user} {generated} {base}
# TortoiseMerge (part of TortoiseSVN - see http://tortoisesvn.net).
cmd.merge.tool.args.tortoise=-base:{base} -theirs:{generated} -mine:{user} -merged:{out}
# AraxisMerge (see http://www.araxis.com/merge-overview.html):
cmd.merge.tool.args.araxis=-wait -merge -3 -a1 {base} {user} {generated} {out}
# The address where Sencha Inspector is located
inspector.address=http://localhost:1839/
# this variable references a json file containing unicode code points to be
# printed in escaped form during code generation.
cmd.unicode.escapes=${cmd.dir}/unicode-escapes.json
#------------------------------------------------------------------------------
# Customizing Configuration
#
# Customization can be handled any of these ways:
#
# 1. Place customizations in this file (ideally at the bottom) and they will
# configure this instance of Sencha Cmd.
#
# 2. Create a "sencha.cfg" file in the folder above this instance of Sencha Cmd
# to be shared by all installed versions.
#
# 3. Create a "~/.sencha/cmd/sencha.cfg" file. On Windows, the "~" maps to your
# %HOMEDRIVE%%HOMEPATH% folder (e.g., "C:\Users\Me").
#
# Your personal settings take priority over common settings (item #2) which both
# take priority of instance settings (this file).
