OkHttp的使用之{RequestBody、FormBody，flutter厂商推送

RequestBody formBody=builder.build();

Request request=new Request.Builder().url(netUrl).post(formBody).build();

Call call=okHttpClient.newCall(request);

call.enqueue(new Callback() {

@Override

public void onFailure(Call call, IOException e) {

//请求失败的处理

}

@Override

public void onResponse(Call call, Response response) throws IOException {

}

});

}

所以我们还有一种方式可以装取键值对，通过ArrayList这样的数据结构。

//首先要有一个RequestParameter类

public class RequestParameter implements Serializable {

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public String getValue() {

return value;

}

public void setValue(String value) {

this.value = value;

}

private String name;

private String value;

public RequestParameter(String name,String value){

this.name=name;

this.value=value;

}

}

List parameter=new ArrayList<>();

RequestParameter rp1=new RequestParameter(“name”,“哈哈”);

parameter.add(rp1);

RequestParameter rp2=new RequestParameter(“client”,“Android”);

parameter.add(rp2);

//创建一个FormBody.Builder

FormBody.Builder builder=new FormBody.Builder();

if (parameter!=null&¶meter.size()>0){

for (final RequestParameter p : parameter) {

builder.add(p.getName(),p.getValue());

}

}

RequestBody formBody=builder.build();

OkHttpClient okHttpClient=new OkHttpClient();

Request request=new Request.Builder().url(netUrl).post(formBody).build();

Call call=okHttpClient.newCall(request);

call.enqueue(new Callback() {

@Override

public void onFailure(Call call, IOException e) {

//请求失败的处理

}

@Override

public void onResponse(Call call, Response response) throws IOException {

}

});

1.3、MultipartBody—文件上传

---

MultipartBody可以构建与HTML文件上传格式兼容的复杂请求体。

File file=new File(Environment.
getExternalStorageDirectory(), “balabala.png”);

MediaType MEDIA_TYPE_PNG = MediaType.parse(“image/png”);

RequestBody filebody = MultipartBody.create(MEDIA_TYPE_PNG, file);

MultipartBody.Builder multiBuilder=new MultipartBody.Builder();

//这里是 封装上传图片参数

multiBuilder.addFormDataPart(“file”, file.getName(), filebody);

//参数以添加header方式将参数封装，否则上传参数为空

// 设置请求体

multiBuilder.setType(MultipartBody.FORM);

//这里是 封装上传图片参数

multiBuilder.addFormDataPart(“file”, file.getName(), filebody);

// 封装请求参数,这里最重要

HashMap params = new HashMap<>();

params.put(“client”,“Android”);

params.put(“uid”,“1061”);

params.put(“token”,“1911173227afe098143caf4d315a436d”);

params.put(“uuid”,“A000005566DA77”);

//参数以添加header方式将参数封装，否则上传参数为空

if (params != null && !params.isEmpty()) {

for (String key : params.keySet()) {

multiBuilder.addPart(

Headers.of(“Content-Disposition”, “form-data; name=”" + key + “”"),

RequestBody.create(null, params.get(key)));

}

}

RequestBody multiBody=multiBuilder.build();

OkHttpClient okHttpClient=new OkHttpClient();

Request request=new Request.Builder().url(netUrl).post(multiBody).build();

Call call=okHttpClient.newCall(request);

call.enqueue(new Callback() {

@Override

public void onFailure(Call call, IOException e) {

();

Request request=new Request.Builder().url(netUrl).post(multiBody).build();

Call call=okHttpClient.newCall(request);

call.enqueue(new Callback() {

@Override

public void onFailure(Call call, IOException e) {
