PUT请求给出400错误请求错误 [英] PUT request giving 400 Bad Request Error
问题描述
我正在使用Google Contact API
实施Contact应用程序.
现在,我尝试通过发送以下格式的放置请求来更新联系人
I'm implementing a Contact application using Google Contact API
.
Now I'm trying to update a contact by sending a put request in the below format
PUT /m8/feeds/contacts/default/full/{contactId}
If-Match: {lastKnownEtag}
GData-Version: 3.0
Content-Type: application/atom+xml
我将XML作为字符串发送给请求主体. 这是我的xmlString(请求正文)
And I have the XML as a string that I'm going to send as a body of the request. This is my xmlString (Body of the Request)
<?xml version="1.0" encoding="UTF-8"?>
<entry xmlns:gd="http://schemas.google.com/g/2005" gd:etag="*">
<id>http://www.google.com/m8/feeds/contacts/default/base/1785xxxx</id>
<catagory scheme="http://schemas.google.com/g/2005#kind" term="http://schemas.google.com/contact/2008#contact"/>
<gd:name>
<gd:fullname>abc</gd:fullname></gd:name>
<gd:email address="abc@gmail.com" displayName="abc" primary="true" rel="http://schemas.google.com/g/2005#work"/>
<content type="text">Notes</content>
<gd:phoneNumber primary="true" rel="http://schemas.google.com/g/2005#other">9090xxxxxx</gd:phoneNumber>
</entry>
我已经编写了以下代码来发送PUT请求以更新联系人.
I have written the below code to send a PUT request to Update a Contact .
String getUrl = "https://www.google.com/m8/feeds/contacts/default/full/"+contactID+"?oauth_token=" + accessToken;
URL url = new URL(getUrl);
HttpURLConnection con = (HttpURLConnection) url.openConnection();
con.setDoOutput(true);
con.setRequestMethod("PUT");
con.setRequestProperty("Content-Type", "application/atom+xml" );
con.setRequestProperty("GData-Version","3.0");
con.setRequestProperty("IF-MATCH", "*");
OutputStreamWriter output = new OutputStreamWriter(con.getOutputStream());
output.write(xmlString);
// xmlString is the body of the request
output.flush();
output.close();
System.out.println(con.getResponseCode());
当我尝试在OAuth 2.0 Playground
中发送请求时,联系人已成功更新.
但是,当我尝试运行上述程序时,我得到了
When I tried to send the request in OAuth 2.0 Playground
, the contact is updated successfully.
But when I try to run the above program I'm getting
400错误的请求错误
400 Bad Request Error
我不知道我要去哪里.任何帮助将不胜感激!
I don't know where I'm going wrong. Any help would be appreciated!
推荐答案
最后,我找到了我要去的地方.
Finally I have found where I'm going wrong.
我的xmlString无效. <entry>
标记需要另一个名称空间xmlns="http://www.w3.org/2005/Atom"
,在 https://developers.google.com中未提及/contacts/v3 ( Google Contact API ).
这就是为什么我收到400错误的请求错误的原因.
My xmlString invalid. <entry>
tag requires another namespace xmlns="http://www.w3.org/2005/Atom"
which is not mentioned in https://developers.google.com/contacts/v3 (Google Contact API).
That's the reason why I got 400 Bad request error.
有效xmlString
Valid xmlString
<?xml version="1.0" encoding="UTF-8"?>
<entry xmlns:gd="http://schemas.google.com/g/2005" gd:etag="*" xmlns="http://www.w3.org/2005/Atom">
<id>http://www.google.com/m8/feeds/contacts/default/base/1785xxxx </id>
<category scheme="http://schemas.google.com/g/2005#kind" term="http://schemas.google.com/contact/2008#contact" />
<gd:name>
<gd:fullName>name</gd:fullName>
</gd:name>
<gd:email address="juli@gmail.com" displayName="juli" primary="true" rel="http://schemas.google.com/g/2005#work" />
<content type="text">Notes</content>
<gd:phoneNumber primary="true" rel="http://schemas.google.com/g/2005#other">9090xxxxxx</gd:phoneNumber>
</entry>
