 76 |       (except as stated in this section) patent license to make, have made,
 77 |       use, offer to sell, sell, import, and otherwise transfer the Work,
 78 |       where such license applies only to those patent claims licensable

 80 |       Contribution(s) alone or by combination of their Contribution(s)
 81 |       with the Work to which such Contribution(s) was submitted. If You
 82 |       institute patent litigation against any entity (including a
 83 |       cross-claim or counterclaim in a lawsuit) alleging that the Work
 84 |       or a Contribution incorporated within the Work constitutes direct
 85 |       or contributory patent infringement, then any patent licenses
 86 |       granted to You under this License for that Work shall terminate
 87 |       as of the date such litigation is filed.
 88 | 
 89 |    4. Redistribution. You may reproduce and distribute copies of the
 90 |       Work or Derivative Works thereof in any medium, with or without
 91 |       modifications, and in Source or Object form, provided that You
 92 |       meet the following conditions:
 93 | 
 94 |       (a) You must give any other recipients of the Work or
 95 |           Derivative Works a copy of this License; and
 96 | 
 97 |       (b) You must cause any modified files to carry prominent notices
 98 |           stating that You changed the files; and
 99 | 
100 |       (c) You must retain, in the Source form of any Derivative Works
101 |           that You distribute, all copyright, patent, trademark, and
102 |           attribution notices from the Source form of the Work,
103 |           excluding those notices that do not pertain to any part of
104 |           the Derivative Works; and
105 | 
106 |       (d) If the Work includes a "NOTICE" text file as part of its
107 |           distribution, then any Derivative Works that You distribute must
108 |           include a readable copy of the attribution notices contained
109 |           within such NOTICE file, excluding those notices that do not
110 |           pertain to any part of the Derivative Works, in at least one
111 |           of the following places: within a NOTICE text file distributed
112 |           as part of the Derivative Works; within the Source form or
113 |           documentation, if provided along with the Derivative Works; or,
114 |           within a display generated by the Derivative Works, if and
115 |           wherever such third-party notices normally appear. The contents
116 |           of the NOTICE file are for informational purposes only and
117 |           do not modify the License. You may add Your own attribution
118 |           notices within Derivative Works that You distribute, alongside
119 |           or as an addendum to the NOTICE text from the Work, provided
120 |           that such additional attribution notices cannot be construed
121 |           as modifying the License.
122 | 
123 |       You may add Your own copyright statement to Your modifications and
124 |       may provide additional or different license terms and conditions
125 |       for use, reproduction, or distribution of Your modifications, or
126 |       for any such Derivative Works as a whole, provided Your use,
127 |       reproduction, and distribution of the Work otherwise complies with
128 |       the conditions stated in this License.
129 | 
130 |    5. Submission of Contributions. Unless You explicitly state otherwise,
131 |       any Contribution intentionally submitted for inclusion in the Work
132 |       by You to the Licensor shall be under the terms and conditions of
133 |       this License, without any additional terms or conditions.
134 |       Notwithstanding the above, nothing herein shall supersede or modify
135 |       the terms of any separate license agreement you may have executed
136 |       with Licensor regarding such Contributions.
137 | 
138 |    6. Trademarks. This License does not grant permission to use the trade
139 |       names, trademarks, service marks, or product names of the Licensor,
140 |       except as required for reasonable and customary use in describing the
141 |       origin of the Work and reproducing the content of the NOTICE file.
142 | 
143 |    7. Disclaimer of Warranty. Unless required by applicable law or
144 |       agreed to in writing, Licensor provides the Work (and each
145 |       Contributor provides its Contributions) on an "AS IS" BASIS,
146 |       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
147 |       implied, including, without limitation, any warranties or conditions
148 |       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
149 |       PARTICULAR PURPOSE. You are solely responsible for determining the
150 |       appropriateness of using or redistributing the Work and assume any
151 |       risks associated with Your exercise of permissions under this License.
152 | 
153 |    8. Limitation of Liability. In no event and under no legal theory,
154 |       whether in tort (including negligence), contract, or otherwise,
155 |       unless required by applicable law (such as deliberate and grossly
156 |       negligent acts) or agreed to in writing, shall any Contributor be
157 |       liable to You for damages, including any direct, indirect, special,
158 |       incidental, or consequential damages of any character arising as a
159 |       result of this License or out of the use or inability to use the
160 |       Work (including but not limited to damages for loss of goodwill,
161 |       work stoppage, computer failure or malfunction, or any and all
162 |       other commercial damages or losses), even if such Contributor
163 |       has been advised of the possibility of such damages.
164 | 
165 |    9. Accepting Warranty or Additional Liability. While redistributing
166 |       the Work or Derivative Works thereof, You may choose to offer,
167 |       and charge a fee for, acceptance of support, warranty, indemnity,
168 |       or other liability obligations and/or rights consistent with this
169 |       License. However, in accepting such obligations, You may act only
170 |       on Your own behalf and on Your sole responsibility, not on behalf
171 |       of any other Contributor, and only if You agree to indemnify,
172 |       defend, and hold each Contributor harmless for any liability
173 |       incurred by, or claims asserted against, such Contributor by reason
174 |       of your accepting any such warranty or additional liability.
175 | 
176 |    END OF TERMS AND CONDITIONS
177 | 
178 |    APPENDIX: How to apply the Apache License to your work.
179 | 
180 |       To apply the Apache License to your work, attach the following
181 |       boilerplate notice, with the fields enclosed by brackets "[]"
182 |       replaced with your own identifying information. (Don't include

 8 | - [ ] TODO 
 9 |   
10 | ### agent features
11 | - [X] HTTP proxy(support GET PUT POST DELETE to target server)    
12 | - [ ] HTTPS proxy(support GET PUT POST DELETE to target server)    
13 | - [X] FTP adaptor(support GET POST DELETE to target server)    
14 | - [ ] SFTP adaptor(support GET POST DELETE to target server)

21 | - [ ] download log file  
22 | - [ ] client and target mapping(host->host:port)
23 |  
24 | ## Example     
25 | First, put target method(m), target url(u) to agent server's url as query string.    
26 | Then, write the body follow the target server's requirements.    
27 | Finally, get the response from target server.    
28 | 
29 | ```go
30 | 	var m, u string
31 |

33 | 	m = base64.StdEncoding.EncodeToString([]byte("PUT"))
34 | 	u = base64.StdEncoding.EncodeToString([]byte(u))
35 | 	client := &http.Client{}
36 | 	req, err := http.NewRequest(http.MethodPost, "http://localhost:8000/agent?m="+m+"&u="+u, strings.NewReader("PUT http://localhost:8001/test?a=1&b=2"))
37 | 	if nil != err {

41 | 	resp, err := client.Do(req)
42 | 	if nil != err {
43 | 		fmt.Printf("%v\n", err)
44 | 		return
45 | 	}
46 | 	fmt.Println(resp.StatusCode == 200) //check the response status
47 | 	fmt.Printf("PUT:\n %v\n", resp)
48 | 	buf := new(bytes.Buffer)
49 | 	n, err := buf.ReadFrom(resp.Body)
50 | 	if nil != err {

54 | 	fmt.Println(n)
55 | 	s := buf.String()
56 | 	fmt.Println(s)
57 | 	buf.Reset()
58 | 	
59 | 	
60 | 	m = base64.StdEncoding.EncodeToString([]byte(http.MethodGet))
61 | 	u = "ftp://cme:CMEpassword1&@172.16.4.14:2121/a/admin.go"
62 | 	u = base64.StdEncoding.EncodeToString([]byte(u))
63 | 	req, err = http.NewRequest(http.MethodPost, "http://localhost:8000/agent?m="+m+"&u="+u, nil)
64 | 	if nil != err {

71 | 		return
72 | 	}
73 | 	fmt.Println(resp.StatusCode == 200) //check the response status
74 | 	fmt.Printf("GET:\n %v\n", resp)
75 | 	buf = new(bytes.Buffer)
76 | 	n, err = buf.ReadFrom(resp.Body)
77 | 	if nil != err {
78 | 		fmt.Printf("%v\n", err)
79 | 		return
80 | 	}
81 | 	fmt.Println(n)
82 | 	s = buf.String()
83 | 	fmt.Println(s)
84 | 	buf.Reset()
