提交参数有一下注意：
1、Content-Type参数必须写明。格式为：multipart/form-data; boundary=----footfoodapplicationrequestnetwork，前面四条短线后面自定义字符串，只要不与其他字符串冲突就行。
2、form-data参数格式。
|
buffer.append("------footfoodapplicationrequestnetwork\r\n"); buffer.append("Content-Disposition: form-data; name=\""); buffer.append(parameter.getKey(i)); buffer.append("\"\r\n\r\n"); buffer.append(parameter.getValue(i)); buffer.append("\r\n"); |
参数说明：
第一行为form-data的请求头，也就是boundary前面再加两个短线，貌似必须要加上\r\n。
第二行为form-data的参数名。
3、form-data结束标志。格式为：------footfoodapplicationrequestnetwork--\r\n
在boundary前加两个短线，在后加两个短线和\r\n。
