压缩jsonp请求中传递的数据 [英] compress the data passed in jsonp request

问题描述

我正在尝试将大数据（图像数据最多90,000个字符）从一个域传递到我正在使用jsonp的其他域，因为使用jsonp传递的数据大小有限我在数据包中发送数据。有没有办法压缩传递的数据，所以数据包的数量会减少

}，
错误： function （jqXHR，textStatus，errorThrown）{
  if （ window  。 console ） console  .log（ 错误... + textStatus +   + errorThrown） ; 
 
} 
}）; 

解决方案

.ajax（{
类型： GET，
url： http：//sys108/restnew1/RestServiceImpl.svc/GetData，
data：{
imagedata：s
}，
dataType： jsonp，
contentType： application / json; charset = utf-8，
成功： function （data）{

}，
error： function （jqXHR，textStatus，errorThrown）{
if （ window 。 console ） console .log（ 错误... + textStatus + + errorThrown）;

}
}）;

是的，有一些限制。请阅读我的博客了解更多详情

此外，当你是序列化JSON也有一些限制。您可以通过修改web.config文件来避免这种情况，如下所示

 <  配置 >  
 <   system.web.extensions  >  
 <  脚本  ing  > ;  
< webservices> 
< jsonserialization maxjsonlength =   102400 /> 
 < /   webservices  >  
 < /   scripting  >  
 < /   system.web.extensions  >  
 < /   configuration  >  

I am trying to pass large data(image data up to 90,000 characters) from one domain to other for which i am using jsonp, as there''s limitation to size of data passed using jsonp i am sending the data in packets. Is there any way to compress the data being passed so the number of packets will get reduced

     $.ajax({
         type: "GET",
         url: "http://sys108/restnew1/RestServiceImpl.svc/GetData",
         data: {
             imagedata: s
               },
         dataType: "jsonp",
         contentType: "application/json; charset=utf-8",
         success: function (data) {

               },
         error: function (jqXHR, textStatus, errorThrown) {
             if (window.console) console.log("Error... " + textStatus + "        " + errorThrown);

         }
     });

解决方案

.ajax({ type: "GET", url: "http://sys108/restnew1/RestServiceImpl.svc/GetData", data: { imagedata: s }, dataType: "jsonp", contentType: "application/json; charset=utf-8", success: function (data) { }, error: function (jqXHR, textStatus, errorThrown) { if (window.console) console.log("Error... " + textStatus + " " + errorThrown); } });

Yes, there are some limitations. please read my blog for more details

In addition, when you are serializing JSON also have some limitations. you can avoid this by modifying your web.config file as follows

<configuration>
<system.web.extensions>
<scripting>
<webservices>
<jsonserialization maxjsonlength="102400" />
</webservices>
</scripting>
</system.web.extensions>
</configuration>
